Title: Peerless 930-010 Advice needed!
Post by: Davehuge on September 06, 2019, 10:32:02 am

Hi all

I just got a Peerless 930-010 6 speed gearbox. When I opened it up I found the aluminum casing is badly worn, where the axle exits the gearbox.

I can see there's slots where bearings could be fitted, one on each axle. Can I just go ahead and fit bearings on each axle?

Thanks, Dave.

I've attached a photo...

I don't understand why there's no bearing in there?

Surely a steel driveshaft rotating in an aluminum casing isn't going to last long?  :confused:

Yes you can install bearings in the housing.

Hi Negrey

Thanks. Got the bearings and installed them. Looks and feels much better.   8)

Dave, 

   To answer your question:  The aluminum alloy Peerless uses for their transaxle cases has a small amount of silicone in it so that the aluminum bore that the axle rides through is actually a "bushing."  Most OEMs don't want to pay extra for bearings, so they specify no-bearings, and the aluminum alloy works fine for light-duty lawn mowing. 

   I also notice that the bearings in your picture look like ball bearings.  Peerless also offers needle bearings for these axles for better load-carrying capabilities.
