Water in Case 630 differential

Report to Moderator

Took the brakes off today because oil was seaping out of vent hole on bottom of the brake cover casting. On the right side one cover stud thread broke out before the nut did so I just took it out instead. When I got it out it was draining water from the differential housing. I caught about 6 Qts of water and 16 Qts of oil from this hole. Where did the water come from? The engine block is still full because I checked. I was afarid of in internal crack that was leaking water throtug the torque tube, but it doesn"t look like the torque tube on the 630 communicates with the differential like on the older tractors with wet clutch.

As soon as I am finished with the brakes I am going to remove the top cover on the differential and flush it, or should this be done first? The water did not look rusty like it does from a radiator that has been run in an engine with no antifreeze. I hate to look inside for fear of what I might find.

Also, could not find the drain plug where am I over looking it?

That is what I had planned to do. I guess you did remove the inspection plate and look inside. That is probably worth the cost of the large gasket, or maybe I will be able to see inside with a flash light well enough when I pull the bearing carriers out to relace the seals as part of my brake repair procedure this weekend.

So what did you find in the housing when you got inside. Much damage, little damage? What, if anything, did you replace because of the water?

Today's Featured Article - Recollections of a John Deere GP - by Charlie Cook. I grew up on my dad's 280 acre general farm in Western Michigan. Dad's only tractor when I was very young was the old GP. My first recollection of this tractor was when dad allowed my brother and myself to ride on the tractor with him driving. One of us would sit on the left fender (away from the clutch) and other would sit on the gas tank and hold onto the crankcase breather pipe. ... [Read Article]
