Grease

[TinCanMan]

When replacing the front wheel propeller drive shaft and couplings on an L3750 should grease be applied to the splines or should they be assembled dry?

I would grease it.

I equate it to any other splined shaft connection....a little lube is a good thing.

You're not going to take it apart again, so best to give everything a little bit of slickness.

Yep a little grease will help with wear and moisture intrusion issues.

I would definitely apply grease to reduce wear.

Thanks to all, grease it is.
