: John this is a common problem.
: There are 2 different laygears used in
: the GT-6.
: The corrective action on the big TR
: box, which shares this problem, is to
: fit replacement bearings with an outer
: race, if the bores aren't too badly
: worn.
: This mod doesn't require the bore be
: machined, but I've not found a like
: bearing suitable for the spit box.
: In lieu of metal spraying to restore
: the bore, you could consider opening up
: the bore diameter to accept pressed in
: hard sleeves to act as the outer race.
: This would require some serious
: precision machining.
: Also consider that once the
: bearings/bore get worn, the gear starts
: running off center and the gear teeth
: wear.
: Depending on how badly worn the gears
: are, you could wind up with a little
: main gear noise after all is done.
: One other point to check closely are
: the thrust surfaces. They will look
: fine but are often worn to the point
: that you'll wind up with too much
: end-float, with the standard washers.
: What gearbox, early, late, ## off the
: top of the case?

: I need to replace the lay gear in my
: transmission. The bores are worn
: oversize. So far I haven't had any luck
: locating a replacement. Has anyone
: tried to have the bores of the gear
: metal sprayed and ground back, sleeved,
: or used larger needle bearings?
