OK ClevTrev, tell us why they aren't(?!). Because they are made wrong?

I can only conclude that the drawings they were made to are incorrect.
The gears I am referring to are G10 and G7 the fixed gears on the layshaft. These were purchased in the last year, and I have just got round to fitting them. The gears were ordered with a layshaft, at the same time.
To start with, one of the gears would not go on to the shaft, so the gear had to be filed out to fit.
With G10 in place, tried to put shaft into bearing, would not enter. Half a thou oversize. ( Both ends)
Used old shaft, gear G10 had to be further reworked to make it fit the old shaft.
Then putting the gearbox into checking fixture, found could not get 1st gear, no way. G9 would not enter G10.
Found another G 9 and that would just enter. BUT, then find that only one of the dogs was touching the G9 , the other 8 dogs were up to .025" away from touching. That means the gear would only be driven by the one dog, which I think would be a disaster waiting. Ditto for the G7.
That means there are three useless parts to go back.
So it would appear that the drawings must be wrong, given that the parts are now made to drawing. At least, that`s what we are told. I may be wrong. But I just hope no one else has fitted any of these gears, that might have appeared to assemble.
