THRUST WASHER, 2nd gear, 0.121" - 0.124"
Part Number: 153239
Notes: 153239 is part of the steel 2nd gear bush upgrade originally introduced by Triumph for use in Stag boxes and Police spec gearboxes for 2500 saloons. It works very well in TR boxes and is as near bomb proof as anything. Triumph use selective thrust washers (129941 & 129944) to obtain correct end float for 2nd and 3rd speed gears. If the thickest has to be used, the 2nd speed gear can be moved 0.017” further away from the mainshaft splines and this reduces the life of its synchro ring, 113431, by around 50%. The gearboxes are getting on in years and wear is appearing where it didn’t in the “old days”. Using the thicker 153239 helps to redress this problem and restore the working life of marginal synchromesh. Any serious TR gearbox rebuilder will find 153239 & 153239A a very useful aid and should consider them instead of fitting ever thicker 2nd gear adjustment washers. It is recommended that all 3 brass bushes be replaced with steel ones. 1st & 3rd gears should use 153238 instead of 129940.... See more
