Getting the slipper assembly in & out : is there a knack?

[colmo]

I ran my BJ4WE last night, but had to replace the spur as the motor came loose and shredded it.

It was a bugger to get out, and a complete nightmare to get back in (very little time between heats!) - I ended up running my B4 in the 4wd final as a result.

Is there a trick to doing this job more easily?

Also looking at ball ended drivers for getting at those accursed motor screws (blocked by the battery posts...argh!)

It is a bit tricky to get the slipper back in but I found if you put the rear shaft in before you slide the bearings into the top of the housing, hold it there with 1 hand then lift the front shaft up til it hits the top deck you can just get it in without loosening the top decks.

As for the allen driver I got one from RS Components 2.5mm long ball end driver and it does the job perfect! Plus if I remember rightly it was only £4.

Trick is to get it in right first time to prevent motor from moving. (No disrespect)

I used to use a combination of a ball end driver and then a cut down Allen Key to get the final bite.

The Spur Can be changed easily, as you pull the slipper assembly out you need to rotate the wheels so that the prop shaft pins point up/down and it flies out.
