Ok guys I just bought a D2 3j. I need parts and repair manuals reproductions are fine. Where is the best place to get them I am going to be swapping the pony for another that needs a bearing so I will need to find numbers and I will be asking where to find that next.

Any tips and tricks for swapping the pony would be greatly appreciated!

I need oil and temp gauges Is there a direct replacement for these ? Don’t need replicas just something that works preferablely that fit original holes if possible

Also I need to clean pony gas tank. I am going to do the home grown version of electrolysis and then use what looks like an epoxy gas tank sealer. Has anyone done this and what was your results ?

I would like to add a fuel bowl with shut off under gas tank since my shut off currently doesn’t work Has anyone done this and is there one that fits cleanly up under the pony tank

Lots of questions I now but so much to learn and fix on my machine

Thanks

Manuals, you need to search Ebay for them, with your serial number you can get the correct used manuals.
Why do you need to swap the pony? Do a SEARCH on here. Neil has some pretty extensive writeups on a couple of D@ projects he is working on. Both the J series and the U series.
Need to post your Serial number as there are a couple of variations over the basic block.
Gauges? Aftermarket will get you by for a while, may need to make adapter plates.
I sand blasted the inside of mine and it has never rusted much in 15 years. Keep it as full as practical.
Any aftermarket fuel bowl will fit up under there.
Post some pictures when you get that figured out!

Try for original CAT manuals and parts book. For what you will spend on the reproductions you can usually find originals. Even if they are dog eared they are more legible than most of the reproductions.

By now it is rare to find a machine that still has the original large gauges. Almost all will already have the adapter ring to use a standard 2"?? Gauge. That is what is available from CAT and the last time I bought one from them, I got ANOTHER adapter ring and waited on a backorder of a few machine screws and lock washers I didn't know was on the order.

I use RED KOTE compound in the gas tanks. It uses acetone as the final prep and you can thin the single part material with acetone if you don't have anything larger than pinholes to seal up. Any that you pour back out you can reseal in the can and use later on other projects.

For cleaning i used very hot water and strong degreaser with a handful of nuts or even gravel and sand and shake and tumble until all the loose stuff is removed. I am interested in hearing more about your electrolysis process.
D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time😄

My serial number is 3J 1846

Im swapping the pony because the original died with a clunk last time I tried to start it. It also has a crack in the water jacket and I found on in much better shape. With two I’ll have options to keep it running and rebuild one to close to new standards

I have the original gauges but they don’t work and I’m putting this girl back to work so I need functioning gauges. I will eventually get the originals rebuilt

I think I have found a sediment bowl that should tuck up nicely under the tank I will definitely post when I get it installed

If your looking to get your guages rebuilt I had my guages rebuilt by a place in Ca.
Palo Alto speedometer. The guages were for my cat twenty two. They did a great job!
Just my .02 cents

What did they charge to rebuild the gauges?

Ok! A clunk is never good.
There were a couple in the "For Sale" section a while ago.
A D2 pony is the same as the D4 pony which will get you most of the parts you are looking for to rebuild/swap to get a running engine.

The "died with a clunk" is directly related to the lack of a gas valve or failure to use it. If the gas supply isn't shut off, after the pony stops, the motion of the tractor will shake the float and needle so the gas in the tank leaks into the pony cylinders and migrates into the oil sump. Next startup or maybe the next few startups take out the connecting rod bearings and you get that expensive clunk!

Shut off the gas every time. I believe it is best to shut it off and let the pony idle until it burns the gas out of the carb bowl. This leaves less varnish behind when the pony is not used regularly so the gas in the bowl evaporates between uses. I never use my mag switches. If someone wanted to play a trick on me they could switch it off and I would be cranking away trying to start the pony and wondering what was wrong!

I’ll remember that for when I’m ready to have them rebuilt

I was pretty sure the clunk was bad. I put new oil in the pony before I started it but obviously the damage was already done it just waited for me to get home to unload it off of the trailer to die. I have a motor on the way so I’m good there I will definitely be putting a new shut off on the tank before I fire her up again. Thanks

Hal, the main bearing assembly design is poor on the D2 / D4 pony engine. Two checks are axial play (how much does the crank move forwards and backwards - 010 to 015 / 025 max) and radial play (how much does the crank move up and down - 005-010 / 015 max). If you good engine moves more than that, pull the top cover and check the dowels that locate the main bearings, which are plain round. If the dowels are loose, they can permit fore-and-aft movement of the crank. If they are and the bearings are still serviceable (essentially a snug fit in the bore, and not beyond service level on radial play), then just turn the bearing enough so that you can drill a new dowel hole. Replace the dowels (get them from Cat). You don't want your replacement pony to also go clunk....
Also, if the mag shaft breaks, that can be a sign of main bearing wear / slop

I let a buddy drive my tractor at a show, later I was roping like a fool, wanting to cuss before I discovered the mag switch. Like you, I never turn it off.
