4010 inframe overhaul

4010 guy · Mar 2, 2010

I have a 4010 that has shown some leakage out of one of the weep holes on the left side of the block. I've been told that this is the first sign of a possible overhaul. i also have some raw oil comming out of the exhaust manifold - figure it might be a worn valve rod guide. Someone told me i could do an "inframe" overhaul - get's everything taken care of except the cam shaft seals.

Anyone out there with any experience doing this? Good idea or not? Difficult to do? Thanks for the help.

Occasional leakage from a weep hole is nothing to get too concerned over. The weep holes are there just for that reason, but if the leakage is more than occasional then the sleeve O-rings are failing, and most likely, due to the age of the 4010, the grooves that the O-rings sit in are eroded away also and new o-rings won't fix it. There is a way to fix it, but I doubt you will be doing it without taking the block to a machine shop.

If the tractor is a diesel, that raw oil might just be unburned fuel. Take the tractor out and make it WORK hard for awhile and it may clear up.

In frame overhauls are half-azz fixes. You can never get things cleaned up like they should be.You can't replace the cam bearings.You can't replace the rear main seal.Can't mic the main bearings. At the cost of parts today, I'd pull it out and do it right or leave it alone.

I agree with Mr T work your tractor and see if it clears up. Tractors that are just started and never really warmed up will show some sighs of this. Most of these JDs weeped a little and slobbered oil some. Rarely do you find one without oil stains around that area. Ive seen them do this for OOOH 3 or 4 thousand hours. So get that baby tore down quick you don't have much time. ED

Well, actually you can mic the mains. It just takes a special micrometer to do it. There are some that have very thin tips that can be slid up the sides of the journal after the insert is removed or another style that is a right angle and the thimble measures from the angle to the journal.

How many people do you know that has a set of these $200.00 bad boys though. Really wasn't trying to say it couldn't be done but does a tool like this ever pay for itself? Not for me as I said,I don't do in frame overhauls, it's a half azz job at best.

I've got to agree with you. I've never really understood the fascination with doing inframe's on smaller tractor engines. You're really only saving a few hours work and if one goes about it right, most are not that heavy to lift. Really, many times I think one does as much or more work trying to work around things inframe as if they just removed it. Then you can do the cam bearings, rear seal, etc with ease.
If it was an 855 Cummins... I can see doing an inframe, but not a small engine.
