Good day all,

Been away for awhile working so have not had time to read or partake in some of the news here .

Here is my story I have been working on my pup/pony motor when I have the chance and things have been going well. Everything seems to be in fair shape. Have stripped everything down to clean , check and repaint

Was in the process of taking apart my governor . .I got the front plate off with the fly weights, things were dry but in good shape, will oil as per instructions before re-assembly. Took the back off and noticed that the locking tab and nut were rusted, so I took these off and will clean them up before re-installing them. This is were things started to go wrong. Is says in the manual to press or tap the whole rod assembly from the back of the housing threw to the front in order to dissemble the rest of the components. Well the cap at the end of the push rod is brass. So in my great wisdom, NOT, I tapped on it with a piece of hardwood. It didn't come, so I hit it HARDER. Big mistake, as I have now mushroomed the cap,and it is loose on the bearing that is somehow attached to the push rod, which I have yet to figure out how.

My question is this. Is the assembly always this hard to dislodge from the governor housing and how do you get the brass cap with the sooooo small bearing to release from the push rod so I can continue to dismantle. Somehow I feel I just destroyed something perfectly good before I attempted to clean, check and paint. Also is the brass cap and wee bearing still available?

Oh, and yes I should have known better.

Any help would be appreciated,
Cobalt Kid

What model D4 are you working on, because the parts book shows a different governor on the "older" D4's (4G, 2T, 7J etc) compared to the "newer" 6U/ 7U, I'm sure those parts will be out there, though if Cat has them it might be cheaper to buy a good secondhand governor😆. My advice is quit trying to take it apart unless it is all seized up or worn out unless your surname is Hilton or Rockerfeller, because other than repeated good flushes with gas or kerosene, and then replacing the oil that has usually evaporated over the past 60 years, those governors are pretty basic, certainly the one on my D2 was, and provided the butterfly wings are OK, and the push rod slides OK actuating the throttle rod, there's not too much to them.

How much oil does your book say to use, I was told about 2 dessertspoons full, and I used ATF in mine.
regards
Mike

Good day Mike,

Thanks for the advice. I am working on a 7U35147 Don't know exact year?
I was thinking the same thing, maybe getting a good used one from Gemdozer as he is not too far away and he does have good used parts, and his prices are fair.
As for the oil, I think I recall 2 teaspoons of motor oil.

Thanks again,
Cobalt Kid

Your 7U35147 would be a 1955 according to the ACMOC book (darn handy little book I might add too!).👍

Try Florin Tractor Parts in Sacramento for those bits you need if Gemdozer is unable to help, talk to Judy or Dana, they never fail to amaze me with what they have in stock, and more importantly, how reasonable their prices are for new parts.

I'd double check that oil volume, 2 teaspoons sounds too little to me, plus I was told it was to be placed at the "butterfly" end, but I put some at the other end of the governor shaft too when I reassembled mine just to make sure it had some lubrication from start up.

Well thanks to all.
Now I have the year of my dozer, an exploded view of my governor, the amount of oil to be used for lubrication, a place to call for the cap and bearing assembly, or perhaps a complete used one from Gemdozer.

You guys are good,
Thanks again,

Lucky we checked on the oil quantity Kid, though my Mom always said, "believe nothing you hear, little that you read, and all that you see"😆 Though I reckon phildirt sounds like a pretty honest sort of fella and not one to deliberately lead us astray, that oil quantity for the governor is one of the tightest held secrets of Cat Inc. for some reason, it just was never written down too often in any service book.

Look at my post above - page 249, item 14-

That's where my infomation came from- right from the D-315 manual.

Don't seem to be too big of a secret.
