Hello all! Well, I am well into the belly pump reseal project that I said I was going to start. Been taking photos and videos along the way for others who decide they want to take this challenge on. So far it has been pretty easy going. Managed to get the pump out without smashing my fingers or worse.. Cleaned up everything inside and out, pump itself looks good (functioned fine before, just leaked). Replaced the seal on the pump drive. Now, the seal listed on the Case-IH site for the hydraulic control arm is part number 19812D which crosses to a SKF 7512. I ordered this seal and it is not even CLOSE (See photo). Guess I will have to try to reuse the original that was in it. Was still soft and pliable, so I doctored the mating surface up in the casting with a little RTV to try to give it some help. Got my gasket made, and reassembled the pump.
Removed the pump driveshaft seal retainer/carrier and drove out the double lip seal. Still waiting on the two replacements to come in the mail, so am at a standstill. I am about to begin taking the clutch and driveshaft out to replace the input shaft seal as well since I am in there (should have done it when I had the tractor split 3 years ago)... Live and learn. Any pointers for those who have done it in the past through the belly? I don't have the proper equipment here to split the tractor safely, otherwise I would do that. Done a little research in the archives, but figured maybe someone had done it recently that could give me some insight.
Been taking video of the whole process so I intend on posting that up when all finished. I sure appreciate everyone's help through this ordeal. Hope to be the last time I am in the clutch housing for a LONG time.
Also included a photo of the tool we made at my friends place to get the drive cog loose on the pump drive shaft.. A little welding and we are in business.
