GOLD STAR GEARBOX

[Goldie]

I had to strip down my RRT2 gearbox because the mainshaft picked up on the bush in the mainshaft pinnion.

On re-assembly I find that it will not select 1st gear, all the other gears and neutral are fine.

I have the gear selector in the right position.

When moving the gearbox selector to get 1st gear with a screwdriver it seems to start moving the quadrant but will not click in, and stays in neutral.

I only took out the gearbox mainshaft and reamed out the bush in place before putting the mainshaft back in.

There is a spacer behind the 1st gear pinnion and another between the mainshaft pinnion and the innercover bearing.

I have tried changing these around, because I did get them mixed up on dismantling with one being slightly thicker with a bigger OD, but still could not select 1st gear.

Any ideas???

Spinning the mainshaft will help selecting each gear. Are you doing this?The dogs need a little help to engage.Can you spin it up with a rattle gun connected to the mainshaft via a socket.

Thanks, all fixed.
It was the spacer behind the 1st gear pinnion stopping the dogs from engaging.
