Midship bearing.

Post by Keith Clements »

In all the years of Jowett motoring I have never replaced this bearing. But having driven back from the Castle Combe circuit with vibration I had to have a look to find out what was wrong.

Well I had not expected to find five things wrong.

1. I knew the rear UJ was not correct so that was replaced.
2. But whilst doing that I noticed the overdrive support had fractured so that was redesigned and fixed.
3. Then I noticed play in the flange connecting to the overdrive. This was a loose nut on the end of the propshaft even though the split pin was still in place. Obviously poor assembly.
4. But after tightening that there was still play so the prop shaft had to come out to change the bearing.
5. In addition the rubbers supporting the midship housing were worn. So I found the metalastic bushes that had been there when the overdrive had originally been fitted. These needed to be welded back in.

Suitably sized box spanner over the end of the shaft to press the bearing home.

You have to be quick with the MIG welder as the bushes contain rubber!

The slot cut out of the support at the bottom is to allow insertion of the bolts holding the overdrive flange.

Simply Bearings supplied the SKF 5G88506 BALL BEARING 30x62x16 outer width and 24 inner race width.

Scott may remember we suspected a midship problem before going on the Baltic trip and strapped a spare prop onto the chassis.
