Final drive

Post by Rincon » Mon Jul 09, 2018 6:54 am

almost ready to re attach the final drive to main frame. Do I need to use a sealant for final drive to main frame or is it metal to metal contact. The pinon shaft might leak ?

my jd440ic final drives simply showed a thin coating of paint

edit
mine are dry so JimB sounds right, but sure others will advise further

I don't have a 450C manual to check however, my 450E manual calls for using sealant there and at some other points on the final drive. I think you have "wet" steering clutches like the E model. If that is the case, I would think you need sealant.

Thanks, My manual did not say. But maybe I need to re read somewhere. Yes wet cluthches. I would assume it needs sealant.

My manual also didn't say to use a sealant and I didn't. Clean it and torque it.

I won't say there isn't seepage though. I highly doubt I will ever have a rust problem on the belly pan.
