Here we go again! I’m looking for a 3 synchro primary and idler gear to suit a 1071 190 gear box. Anyone have anything available?

Many thanks Tim

I've a few A series primaries and idlers - what the difference between 3 synch and 4 synch for these?

Same length pin either side of the gear.

Tim, does this mean that DPU’s primary and idler might be available...?

Mine are all unequal length shafts, so can’t help.

When I dismantled my 846 box, someone had done this to make a later unequal pin length gear fit..

Apparently it is possible to use the longer pin four sync idler with the right circlip
