Yes I remember the original sleeve gear being quite easy to tap out of the bearing. When I tried to install the new sleeve gear in the new bearing it would not "tap in". I should have stopped there and investigated.Workshop manual 065146
Section D5, Step 10: "Remove the sleeve gear by tapping gently through the bearing into the gearbox"
Section D9, Step 8: "Fit the countershaft (sleeve gear) through the bearing and seal. Fit sprocket spacer in place inside seal"
I've done quite a few - never had to press a sleeve gear into a bearing and would not if the need arose - too much chance of damaging the case pressing it in and later pressing it out. Of course, they are not supposed to be loose in the bearing. Generally, you start it into the bearing wiggling and once in a little it will slide in with no wiggle at all. Sometimes they will get part way in a get stuck - usually means a bit of grit, lint, or maybe dust - pull it out, clean and try again.
In truth, even if it was an easy slip fit in the bearing it wouldn't matter as the bearing spacer and sprocket are sandwiched together and tightened.
No damage to the case when pressing the gear into the bearing as I had the inner race supported with a 1 1/4" pipe nipple.
The challenge, as I see it, will be to get the sleeve gear out of the bearing after the whole assembly is pressed out of the case. Of course the bearing will be damaged by pressing against the balls anyway.
First order of business is to get the sleeve bearing out of the case.
