iS there anywhere I can get a Cush-drive shaft puller in the uk I know Keith Lynas has them across the pond

In the UK - unlikely, I've never heard of anyone having one in stock

 

If you're able you can make something that will do the job

Where it mentions the plate with the hole in (preferably round in shape) it is also a benefit to machine a recess into the area around the hole so that when the plate is pulled forward to locate against the two collars, the collars fit snugly into the recess which helps prevent them from being pulled out of the groove when you start to apply pressure with the puller

A bit Heath Robinson, but it'll do the job.

Thank you for the replies, thought it was a bit of a long shot, looks like I will have to make something then

Reviving an old post.

Recently I had the need to remove three cush drives from 72 and a 73 MAR.  

Using the proper puller, obtained frim Alex Snoop, the first drive was easily removed.  This motor had previously been diassembled.  The second motor also had been disassembled previously and this one removed easily also.

On my own 73 MAR, which had never had the cush drive removed since it was built in 72, it was a bear to remove.  Even with the correct tools the drive spine would not release from the taper.  I applied heat from a propane torch while the pullier held tension.  After talking with Alex on the phone, he suggested a large hammer striking the actual gear puller end to shock the taper loose.  The puller was tensioned via an 18" breaker bar, so there was certainly tension applied to remove the spline cush drive from the crank.

Accepting the fact that I may need to cut the drive and hope it split to release, we gave one last effort using the puller.  The puller threads got a fresh coat of grease.  Tension was applied and still it remained stuck.

As before, the amount of tension was very high.  While ensuring the clamp was secure that was keeping the puller jaws from slipping outward, the drive released almost exploding off the crankshaft.

The cush drive spline was inspected and five cracks were found running along each spline.  A replacement was installed after the seal was replaced and the tapers were lapped together.

Ensure, when removing these drives to stay off to the side in an effort to prevent injury.

It is now reassembled, and hopefully will have no issues.  The reason the drive needed to be removed was to replace the crank seal.  The seal, while still working, was loose in the case and easily removed.
