Replacing main shaft trans brgs

[24 Roadster]

How is the best (maybe only) way to replace the transmission rear drive shaft bearing on a 24 DB?  Does the large nut have to come off the shaft or can the gears slide off and the bearing removed?  If the large nut has to come off, what is the best way to do this.  That is, how do you keep the shaft from turning?

 

Thanks,

I've not done this but am curious if you have the trans installed or removed?  Either way I would try to wedge a piece of wood in there between the case and gears to stop the gears from turning.  I've done that when tearing down/rebuilding engines and want to keep the crankshaft from turning.

As it turns out there was very little torque on the main shaft nut.  The nut retainer (cotter pin) was the main thing holding the nut.  I have the bearings out and will be replacing with sealed bearings.  The trans was installed while doing this.  The engine was not.

Good to know.  I'm glad it was easy.  Was the body on the chassis?  It sounds like it could be done with just removing the driveshaft.

Often times an air wrench will take the nut off. I am very reluctant to use one, but find with transmission flange nuts and pinion flange nuts this saves alot of effort and problems. Rob
