Russ,
A regular 2-armed puller will do the job, at least for the bearing behind the clutch and the layshaft bearings. You will need some form of seperating tool to grasp the bearing of the output shaft. Factory tool is a ring and a spring clip fitted in the groove of the bearing. The ring is then pulled.
At the layshaft, use the 1st and 5th gears to shift the bearing races, just pull them off together.

Russ,
You will find that the ball bearing on the 5th gear output shaft needs cosiderable effort to remove, because when it is drawn off, the shrunk fit spacer/retainer has to come off with it and that is a really tight interference fit. An engineering firm removed both that bearing and the layshaft roller inner races using a press. A press was also used to fit the new layshaft inner races because I found that even when heated to 150 deg C, they shrunk as soon as they touched the shaft and went tight - I was not inclined to drift them on - even with the engineering firm's press, they took some moving. The clutch end bearing, as Piet said, will come off with a sturdy 2 or 3 legged puller.
That was my experience with them - hope that helps.
Regards, Andy
