2 ton fan drive

Hi growlyone,
welcome to the Forum.
Scan below should help.
Early drives had double row ball races for bearings and later ones had bushings.
Should be a slinger for oil control but if the bushings are worn I guess more oil would be passed thru the bushes and so leak oil out the front. Worn bushes and a resulting a worn front cover shaft bore, engine blow by and clogged engine breather would add to the leak problem too. Early engines had a pitifully small breather that was later enlarged to no doubt overcome some of these issues.

The section on the second page "Assembling the Fan Shaft Assembly Complete" should get you there.
Unit is likely stuck by solidified dirty oil residue. Maybe try tapping the drive housing around, to attempt to turn it with a soft face hammer first.

Click on the attachment and click again for enlargement, click again for further enlargement.

Download this or any data you want to refer back to while it is up, soon I will run out of post space again and will need to delete some of the older data.

Hope this helps.
Cheers,
Eddie B.

Hi edb

Could you please tell me what book that info came out of?? Is there a service book for the 2 ton?
I have parts book.

I have this but it’s useless.[attachment=46523]907FB80B-1B4F-4D91-871C-67CFF85D435E.jpg[/attachment]

For what's its worth; back in 1972 I had the fan drive off and disassembled. Bearing was bad and no oil seal, only a slinger. Found a bearing in the parts dept along with an oil seal that would "about" fit the housing.
Went to visit my nephew who was teaching industrial arts in a good size high school. He turned out a new shaft, fit bearing to shaft and to housing. Cut housing for oil seal and shaft for good fit. Broached shaft for fan hub to mount to. Put it together and it's been running ever since with out a drop of oil leak. I'm sure there are others who have repaired fan drives in some similar manner, but that was the fix on mine. It was so loose that fan had rubbed on back side of rad. core, good luck!! Bill Walter
