M931 Leaking fan clutch

[RDUKW]

My M931 has developed a leak at the fan clutch when it engages. It is leaking from between the shaft and the clutch. Can these be rebuilt? I am on a time crunch as I have to take my Class A test on Thursday and I'm worried they will fail me if the fan comes on and I start losing air. Any advice is greatly appreciated.

Thanks
Ryan

Yes they should google bendex if that is what type it is and yes rebuild cause new is maybe 600.00

The data tag is hard to read but it definitely is not Bendix on the tag. Are these standard orings that can be bought from McMaster Carr.

Worst case, disconnect and plug the air line. Then use the bolts provided and mechanically engage the fan for your test.

Thank you for reminding me about that.

Okay I found some info I will share with others for problems in the future. The clutch is made by Evans and is Model # FC367E. Comfort Air in Michigan has the parts to rebuild them http://comfortairgr.com. Also comfort Air has a pdf on their site with a manual for rebuilding the clutch as well http://comfortairgr.com/wp-content/uploads/2013/01/fan-clutch.pdf. I ended up ordering the oring kit with out the end cap seal and it came to around $15. They have any part required to repair the clutch it sounds like.

So for my test I will get a AN plug to cap the line and install the 2 locking bolts. The AN plug sounds like a nice part to have in the truck anyways for future failures.

RDUKW did you ever get a chance to try rebuilding the clutch yet. Just wondering mine is doing the same thing.
