Default Caterpillar Sixty

Hello All,

A Cat Sixty is one of those machines that leaves an everlasting impression on you the first time you see and hear one run. From the first time I saw one running at a show I wanted one.

I purchased this Caterpiller Sixty last week from the widow of Don Green in Northeast, Ohio. I did not know Don but from what I understand from some of his friends, he put a great deal of time and work into restoring this machine. We had it running last night and it really runs and drives nice.

I would like to get an operators manual and a parts book. Does anyone know where I can find a reprint?

Dan

Dan,

You will need to double the size of the barn you plan to build.....

Congrats, will it pull the Advance?

The "shop" is half finished and at 30' x 45' it is already going to be too small. Amy is in complete agreement regarding this. It will be temporary storage until the tractor shed is built next summer.

I believe the Cat will have no problem pulling the Advance around.

Dan:

What is the serial number of the 60. Looking at the fly wheel it is a later cat. The parts books and operators books are different depending on serial number and year. I may have an extra set if you want originals or if not you can go to Jensales and they have reproductions. I have a dozen or more 60's so I know what you are talking about when you said you had to have one.

From what I understand the serial number is located in two different spots of the tractor.
- One on the crank case casting - too faint/rough to de-cypher
- One on the front left side of the frame - covered by the "bumper" framework

Please confirm these are the proper locations for the serial number to be located.

Depending on the year of the tractor it should have a brass tag on either the fender or the seat that has the number stamped in it that ends in either a PA for Peoria built or A for San Leandro built. The later tractors did also have a second serial number tag (brass) between the inspection covers for the engine on the I believe left side. If you post some pictures of the manifolds and left side of the engine we should be able to narrow down the age.

It appears you have the older model of the 60 as indicated by the brass pushrod tubes and the Best style track pads. A look at the exhaust manifold could confirm this.

There should a serial number on a machined pad on the front right of the engine just above the engine side cover. There is also a serial number stamped on the front right frame rail. Reading the frame rail number is pretty hit or miss as that area gets pretty beat up typically.

Attached are a few more pictures of the sixty.

There is something wrong with the carburetor.
1. The tractor runs fine with a carburetor from another sixty.
2. The carburetor that came with the tractor (third picture) has been rebuilt but the engine will only run with the carb choked.
3. If the needle valve on the top the float bowl is adjusted so the spring has very little pressure on it, it will run with intermittent choking.
4. If the adjusting cap for the needle valve on the top the float bowl is completely removed the engine will run without choking it. But poorly.
5. Any suggestions to get the carburetor to work better?
a. Adjust float level?
b. Needle valve problem?

Dan, I never worked on a 60 carb, but have on a 20 carb, smaller version of the one in your photos. I have the problem with the 20, but going through it and making sure everything was set right made a world of difference.
I have the care of a friends 60 and last year it ran real bad,, this year it runs a lot better. We changed the oil, treated the fuel( I think this was the biggest problem) and put Marvel Mystery oil, in oil, fuel and primers as a person who helped the owner rebuild it told us it helped greatly as this engine is still very tight.

Talking Re: Caterpillar Sixty

Dan,
I will tell you two BIG reasons why I'm a steam man:
1) Carburetors
2) Magnetos

Big ol' 60 Cat is an impressive machine, am sure you'll get 'er straightened out, even though it has an example of 1 & 2 above.

Mike

Dan,
I have never worked on your type of carb before. However I have seen this problem before with a lot of the John Deere's. I have always narrowed the problem down to one of two issues.
When the carb was rebuilt a passage was missed,
A jet or passage is plugged OR there is a internal leak related to a jet passage. on the JD it is usually the brass power nozzle that does not fit tight in the cast body. These can be fixed by putting a little solder on them and turning it to fit. By choking the carb you are increasing the velocity internally, which in turn allow it to draw fuel.
I used to glass bead all my carbs before I rebuilt them, I have got to the point that I started to see that the glass would/could get into a passage and I would have a terrible time getting it cleaned out.
I can only tell you that you are going to have to disassemble your carb and inspect it very close.
I hope that this helps.
Matt

Matt and Terry have summed it up. You need to really clean your carb after a good soaking with carb cleaner. Take the float bowl off after removing the main needle adjustjng knob.
Inside (after removing the float) you will probably need to take the needle seat assembly off by removing the 4 screws. A new gasket will be in order there but you can cut your own.
Clean every passage nook and cranny in there. Some compressed air will be helpfull. Sometimes a welding tip cleaner set works well to clean out the passages starting small and working up as sometimes things a full of varnish and can be completely blocked. Just clean everything you can see and reassemble. Also don't overlook the incoming strainer and needle valve assembly for dirt and crud, the gas has to get to the carb before it can do it's job. Hope this helps.

Hi Dan,
nice machine you have there. They sure make great stack music when loaded.
Hope the scan below may help with regards to the correct orientation of the float in the bowl and the method of fuel level adjustment.
Can only back the advice above to be sure ALL passages are clear and ALL jets are present.
Regards,
Eddie B.

I forgot to add make sure your vacuum fuel pump is working OK. I know you can have no vacuum leaks.

You've got a little something funny going on with your exhaust manifold and I can't quite put my finger on it. It looks like the newer style exhaust manifold and has been modified to work with the old style intake manifold. I didn't know such a thing was possible.

If it is the old style manifold then he has boxed out the intake preheat port and you're missing that apparatus that goes down to the aircleaner.

The flywheel is certainly off the newer 60's with as many holes as it has but your track pads are also most certainly the old track pads from the Best style.

Not that any of that really matters in the grand scheme of things but I'm always curious about what farmer brown did to keep his equipment going.

I got the carburator straightened out. The gasket between the float chamber and the bronze body of the carburator was missing a hole that allows fuel to pass between the two parts. Now the engine starts easily and runs well.
