    Posted: 7 hours 46 minutes ago at 8:48am
I have the wet bellhousing and I need seals for the crankshaft . There are 2 separate seals … one facing the engine and the other facing the bellhousing. They are identical National # 77286HC I’ve tried a few places to match them up but I need the Original Allis Chalmers part number for them. All I can find is the seal for a dry bellhousing housing.
Reliance sent a seal they say is a double lip but it sure doesn’t look like one . Any help appreciated or where to find the parts manual

What is the serial number of the tractor and engine? Four, or six cylinder?
That's All Folks!

74029500 seal from Minnpar is about $50. Pretty sure the 670 had same rear seal as 685/11000 series.

Yes...I concur with Trevor....that part number should be 74029500...available from Minparr.  should be applicable to tractor serial numbers 27201-27950 and 34U27951-up. My parts books do not show any configuration of 2 seals....have no idea of what you might have going on there?  Yes that seal is the same for both the 3500 and 11000 engines
