loop frame clutch ctr/shaft

Hi, does anybody know an easy way (easier than beating seven shades out of it with a mallet?) to get the splined clutch hub back onto the input shaft of the 4speed g/box. I had to use a puller to get it off and after replacing all of the bearings in the box I do not want to start hitting it!

Have you tried warming the hub up and leaving the box in the freezing cold garage.
Pop the hub in the oven at 150 degrees for a while, then rush it out to meet it’s mate.

Thanks Don, yes I think thats my next move, perhaps just needed someone to think the same!

Have you tried it yet? And if so did it work?
