Thread: Puller for R380 mainshaft collar?

Then needs a strong puller attached to it. Presume there is something available to make the job easy. If so, could anyone suggest what and also where to obtain one?

Dont be afraid to use a little heat.

Problem is cannot use much heat because the collar is half way into aluminium housing, which conducts it rapidly and also slghtly too much will melt it and destroy the housing for future use.

Hydraulic bearing puller from trade tools or any of the tool places will do it easily.

Regular hydraulic gear and bearing puller will do it.

I have one like this which I used to rebuild an R380. Made it a breeze. FWIW I used a press as well.

Looks like the sort of clamp in the left corner of box in the illustration of this puller is the important part that should make the job easy. Cannot get the hook end of ordinary puller legs into the collar groove because when the collar is in place, it is partly inside the aluminium rear section of the transmission case.
