I bought a 75 4000. It s an 8 speed diesel with independent PTO.
It has a leak coming from the "nub" located at the 5 o clock position on the hydraulic pump cover behind the right foot rest. Has anyone ever encountered or fixed a similar leak? If there s an o-ring sealing this, I don t know how to get to it.
Any advice is appreciated!

I don t usually like doing things halfway but I m this case I decided to roll the dice. I was able to pry the pump about 1/16" away from the tractor and I squirted some gasket maker up into the crack. I don t have high hopes that it will fix it but it was worth the experiment to me. Time will tell. I will report back when I ve determined whether it holds the fluid in (at least in the short run.

That is a dowel pin that helps locate the pump, you would possibly have to remove the pump to get to it. From what I remember should be a blind hole, there is no seal or "O"ring on it. Could be the pump gasket is broken at that point.

Today's Featured Article - Restoration Story: 1964 JD 2010 Dsl - Part 2 - by Jim Nielsen. Despite having to disassemble the majority of my John Deere 2010's diesel engine, I was still hopeful I could leave the engine-complete with crankshaft and camshaft-in the tractor. This would make the whole engine rebuild job much easier-and much less expensive! I soon found however, that the #4 conrod bearing had disintegrated, taking with it chunks of the crankshaft journal. As a resul ... [Read Article]
