Triumph TR3B (TCF) TR4-4A-5-250 Uprated Laygears - 4 Synchro
Most TR owners know that the Stag and Police spec saloon gearboxes were uprated by the modifications to the weak zones of the laygear and shaft, and the replacement of the bimetal thrust washers with needle bearing thrusts. The rear end of the shaft and gearbox became 'metric', so this conversion would be quite difficult. Uprated laygears come complete with 3 bearings and fittings. The twin bearings fitted to the rear end each have twice the load capacity of the original (150339). They fit the standard gearbox and layshaft, so no modifications are required. If your gearbox has suffered such a failure, you will appreciate this as a 'fit and forget' solution.
