Every decade or so..

Somehow summer slipped into fall and suddenly it was Thanksgiving again.  Time to gather firewood.  Ole Yeller has been the tool of choice for gathering and processing firewood.  The farm jeep hauls chainsaws and fuel and tows trailers full of wood to the splitter.  Even though we have farm tractors that can be used, the jeep is the better tool for the job.

Ole Yeller doesn't get much attention.  It sets in the barn, waiting for the next job.  It has been a constant helper, starting and running without missing a beat.  But late this summer the jeep didn't want to start.  Once it did start, it ran fine and we continued to just go about business as usual.

When Evan came down for a "jeep day", Barry thought a quick check of Ole Yeller was in order.  The jeep started perfectly and so it was just assumed Ole Yeller had a case of bad gas.  But a couple of days later, the jeep wouldn't start at all.

Jeeps, like old cars and tractors are pretty simple machines.  If you have fuel, spark and compression (timing) they will run.  So Barry started to check those things.  First, he pulled a plug wire and used a screwdriver to ground it to the block.  Cranking the engine produced a spark.  It was possible that the spark wasn't strong enough to jump the plug gap.  Barry pulled the distributor cap and the cap and rotor contacts appeared tarnished.  Not a good sign.  He pulled the plugs, three of which were slightly rusted in place.  Not a good sign.  The plugs were worn with a much larger gap than normal and needed to be replaced.

Maybe it was a time for a tune-up.  Barry couldn't remember when Ole Yeller had been tuned.  A note to Evan and a check of the Farm Jeep chronicles showed the plugs had been changed in '03.  Almost a decade!  Definitely time for a tune up.

After a trip to the local NAPA parts store, Barry pulled the wires and reinserted them in the new cap. He also install the new rotor and plugs.  Trying to start produced nothing?  Maybe he replaced the plug wires incorrectly.  A quick check of the manual and Blue showed the plugs were wrong!

With only four wires the switch is pretty easy.  Try again.  Nothing.  OK, time to check the fuel.  It is dark in the barn (even with the lights on) and but it didn't appear much, if any fuel was getting past the carburetor.  The after-market fuel filter is clear and appeared to have a number of rust particles inside the case.  A quick trip to town produced a replacement filter.

Clearly, fuel flow was an issue.  After the filter change, cranking the engine produced a visible flow of fuel.  But the engine still didn't start.  OK, time to check the timing.  At least with a quick check and adjustment of the points that seems fine.  But no engine fire.  Time to head to the Internet.

A note posted on the CJ2a forum said to recheck all my work, including making sure the plug wires were correct.  There was also a link to a very good paper on timing the engine and in there was a note on how if the distributor had been changed or the oil pump replaced, it might not have been installed in the original position.  This would not change the way the engine operated but it WOULD change the location of the plug wires on the distributor cap.

It was at this point that Barry remembered an email from Evan early in the process which said "Are you sure you didn't have the plug wires in the correct order before you fixed them? I seem to remember battling this before (although it could have been on the '49) and that there was something odd with the firing order."

Barry moved the wires one position clockwise AND the engine fired immediately!  What a marvelous machine.

NOTE TO THE GRANDKIDS:  When you do a tuneup in 2022/23 be sure to watch for those pesky non-standard plug wires...

The Art of the Farm Jeep

Farm Jeep as art?  We have always considered the iconic Willys jeep a beautiful piece of metal sculpture.  A grill and tailgate are part of our garage art collection.  But early last summer, Richard Saxton from the Colorado based arts group M12 (m12studio.org) contacted us at about a real farm jeep arts project.  M12 was planning an exhibition with the University of Toledo's Center for the Visual Arts gallery and had been researching jeeps and their agriculture connections.  We were able to provide some names and contact information for some Farm Jeep historians and collectors who contributed materials to the exhibition.  A description of the short-term exhibit is here - UT News

We drove to Toledo to see the exhibit and had an opportunity to meet Ben Pond, the director of the gallery, and to talk to the students involved in the exhibit.  Some great pictures of the exhibit are here - www.facebook.com/CVAGallery . 

John Ittel's beautiful 1954 CJ3B with a Newgren 3-point hitch is a perfect example of a farm jeep. What made a lovely-to-look-at and interesting exhibit even more special was the opportunity for the students (and the public through pictures) to see the farm jeep in action. Through a tree planting exercise, one can see both the connection to agriculture and the "universal" nature of the jeep. 

The pictures (here) show the "universal jeep" as a pickup, hauling the small trees to be planted, a passenger vehicle, hauling students, and as a tractor.  As a tractor it carries the implement (in this case an auger powered by the PTO (power take off)) to the field and engages the implement with the ground to create the holes for planting.

The planting exercise also gave us a chance to discuss some of the reasons why don't see modern versions of the farm jeep.  Evan is showing why the jeep wasn’t favored by farmers as a tractor.  His location at the back of the jeep approximates where a farmer would be located while driving a conventional tractor, providing easy visual access to the implement.  From the jeep’s driver’s seat, it is much harder to see where the implement is making contact with ground.

We  enjoyed our visit  and discussion with the students and seeing the work of M12 and the CVA Gallery.   It did validate what we have believed all along.  A farm jeep is really a work of art.

Summertime fun - more tractor shows & fun with hydraulics

The first tractor show in May was so much fun, we were determined to attend a couple of more this summer.  It was also a good reason to acquire a jeep hauler (18' tandem axle car hauler) for those out of town trips. 

At all three shows, we were the only "farm jeep" on display, so got lots of attention and visitors.  Having learned from the first show, we continued to use a combination of ads, signs and our notebook to explain the various bits of "farm jeep" equipment.



More fun with hydraulics

It was clear from reactions at the shows we need to display the jeep with a plow on the back to really give people a clear idea of a jeep as a tractor.  That means we need to get the lift working, again. 

Over the years we have used different pumps to power the lift, but wanted to use an authentic pump and eventually found a Newgren pump and bracket.  The pump was sent to a repair shop for reconditioning and was determined to be "worn out" and not repairable.  This sent us on another search for a replacement pump.

One of the joys of working on old jeeps is that you get to meet interesting and extremely knowledgeable people.  Our friend Lonnie knows his Newgren history and told us that the pump was the same as that used on the International Harvester model "C" tractor.  After some time search for a pump, we found one on e-bay.

The pump has been sitting in a box for a while and we did mount it, but did not connect it to the crankshaft before the first show.  So with no other shows planned, Barry decided to hook the pump up and give it a try.  The pump is connected to the crankshaft by a solid rubber disc, which allows for some movement and alignment.

The first test was a failure.  Barry suspected that the pump might be running backwards (it seemed to be pressurizing the tank).  He reversed the pump manifold, but the ram did not move.  At this point, Barry consulted with his friends over at the Tractor by Net (TBN) hydraulic forum about possible solutions.

At the suggestion of the TBN folks, we disconnected the hoses and placed them in a 5 gallon bucket half full of hydraulic fluid.  The bubbles coming from the pressure side showed that the pump was working (and rotating correctly), but not primed.  By pouring some fluid into the "suction hose" we were able to prime the pump and could see it working!

Uplifting

The Newgren lift hydraulic system is pretty basic.  The pump supplies pressure to a control valve located on the top of the reservoir.  When the control valve is in the "hold" (neutral) position, fluid enters the control valve and "dumps" directly into the reservoir.  When the lever is moved to raise the implement, the pump pressure is directed by the valve to the top of the ram, pushing the ram rod out and raising the implement arms up. When the control valve is in the "lower" position, fluid in the ram is returned to the reservoir and the ram rod is pushed in by the weight of the implement.

Since we know the pump is working, we could reconnect the hoses (pressure side to the control valve and return side to the bottom of the reservoir).  After adding fluid to the reservoir and working the control valve a few times, the arms moved up.  Success!  Sort of.

Any pressure on the arms would stop the upward movement.  No way this is going to lift a 200 pound plow.  We may still have a problem if the pump isn't providing high enough pressure.  Or the control valve, although we have taken it apart and cleaned it, may not be working correctly.  And we have leaks in the system.  Unfortunately, those leaks appear to be coming from the top of the reservoir, which means lowering (un-installing) the entire lift.

We have had the lift in and out of two jeeps on several occasions.  While not a terribly difficult task, it is a hard balancing act, not unlike removing a transmission.  So before we attack the leak, we are going to try and build something along the lines of a transmission jack to help us get the job done.

Stay tuned.

Farm Jeep Goes To An Antique Machinery Show

There is Blue, in the middle of a row of fine antique tractors!  After years of saying we were going to take the jeep to a tractor show, we finally did it.

Following up on our last post, Thursday was final preparation day.  The hydraulic pump was bolted on the mount in front of the crankshaft pulley, but not connected and the 265 lb front bumper weight installed (with the help of the engine hoist).  Finally, we gave Blue a quick bath to get the dust off.

One goal of Farm Jeep has been to collect and share information and stories about jeeps being used on the farm.  At most shows, tractors are lined up and each exhibitor determines what, if any, information to provide.  Most provide signs with the owner's information and the date the tractor was built but very few provide additional details.  Believing few people would have seen a farm jeep, Barry resorted to pre-retirement skills and created a short paper-based PowerPoint presentation to accompany Blue.

It had been the plan to drive Blue to the Brown County show, since we can get there on back roads, with only a short stretch of busy highway.  But between the valve and clutch noises, we felt it best to give Blue a ride on a trailer.  So early Friday Barry picked up the rental trailer and loaded up Blue for the 30 minute trip.  It was an easy drive and Barry was soon standing in front of the registration desk asking where he could park Blue.  He explained it was equipped as a tractor and didn't want to exhibit it in the old trucks and cars section.  After a couple of phone calls, he was told to park at the end of a line of John Deere tractors.

Along with the PowerPoint slides, Barry had 3 old ads mounted in picture frames to help tell the story.  After watching people's interest, he determined that a better plan was a loose-leaf notebook with copies of ads from the Web site would be a better idea.  The combination worked very well for the second and third days.  We were the best documented tractor and it was really appreciated by the many visitors stopping by.

People seeing the jeep fell into 3 main groups; those who had never heard of a jeep "tractor", those who had heard, but never seen and then a very few who had used a jeep on the farm or had neighbors or friends who had farm jeeps.  This latter group provide to be the most fun, and it was clear Blue brought back some great memories.

There was a large group of "I'm sorry I sold my jeep and I sure wish I still had it" visitors who also told stories.  There were several vets who wanted to talk about their military jeep adventures and a WWII vet recalling his days in the muddy fields of Europe.  It is  unfortunate that we didn't have a way to record some of the stories.

Friday and Saturday were extremely busy, but by Sunday noon, most of the tractors had been loaded up for home.  We stayed until after lunch, then loaded up for a quick trip home.  It was great fun and we anticipate doing more shows in the area.  Next year will will drive Blue to this one.

All Dressed Up and Someplace To Go!

The Brown County Antique Machinery show is held the first weekend in May each year.  We have been trying to make that show for the past several years, but have never been quite prepared.  We aren't finished, but we are going to take Blue on a road trip "as is". 

Blue is running and even though we are planning to change the motor, it is road worthy.  It lacks a working hydraulic pump and the cable to control the governor.  At least people can see a real Farm Jeep.

The first task was to install the PTO shaft.  This is normally a very simple job, involving installing and bolting the rear shaft flange on the gear box and bolting the shaft in place.  A some point, the splined shaft on the rear of the gear box had been damaged.  The gear box had to be removed and the bolt hole had to be re-tapped.  So the normal 30 minute job turned into a 3 hour task.

The gearbox turned easily, so we filled it with gear oil and started the jeep.  The PTO worked perfectly.  Except for a small leak on the back of the box.  We will need to remove the box and see if it is a quick fix or a tear down.

Several years ago, we find a Willys belt pulley assembly on e-Bay.  It was mis-identified as being for a tractor, but we had done enough research to know a Jeep pulley when we saw one.  It was a paper pulley, instead of the more common steel type, and it had to be rebuilt.  There is still a company - www.paperpulleys.com - that rebuilds paper pulley drums and we had them build a pulley using our frame.  The drum has been sitting on a shelf for a few years.

The pulley gear box had been on the shelf too and we decided to just clean it off and install it as a show item.  The assembly was a simple bolt-on process and the drum turns freely.  We need to paint the gearbox, but that can wait.

In the picture above, you can see the lift arm to the right of the drum being held in place by an original adjustable link.  The second link is rusted solid and will need some work.  For this show, we have used the reproduction links we had on hand.  This should at least give folks a idea of how the lift operates.

Other than a quick bath, we are ready to go.  We will report on our first outing

Farm Jeep Spring

Farm Jeep is coming out of its winter hibernation.  With the garage doors opened we changed the coil on the stand engine, to prepare it for the 12 volt 3a.  After a test start, we removed the engine from the stand and will prepare it for the exchange.  That means removing the face plate, which is a 2a style, and replacing it with 3a face plate.





Too much of a bling thing..

Getting the 3a to be street legal was a year-long struggle.  Among the requirements was working wipers.  The easiest fix was to install two "universal"12 volt wiper motors.  This project was chronicled in an earlier post.  Somehow, those chromed motors stuck out like a sore thumb on the windshield.  There had to be something better.

Original windshield equipment included a vacuum wiper motor on the driver's side and a manual "hand" wiper on the passenger side.  Using a vacuum motor would mean changing the fuel pump (to power the motor) and might be a future change.  For now, we are going to use a painted motor with a built-in switch.

An original hand wiper appeared on e-bay and we purchased it with the idea of restoring it.  However, it was too far gone and a reproduction was our only option.  The reproduction is for the 2a, with the shorter, split windshield.  It is 2" too short to work on the 3a.  A 2" section of rod was welded in the middle to make it the proper length.  We need to find a grommet to finish mounting the wiper.




Ahead is an engine exchange and maybe a wiring re-route to accommodate the governor cable.
