Rebuilding the original 100,000 mile Moss gearbox |

Being a rivet, and held in place by deformation of the rivet's shank, it is at best a soft steel, and prone to further deformation and/or wear over time. In my XK150, after 100,000 miles, the rivet was severely worn, and thus allowed the first gear wheel to over-travel. The www.xklovers.org website contained details of the cause of the jamming, and the solution. In 1993-94, Rob Reilly first documented his experience with fixing the jamming first gear problem with his XK120 Moss gearbox. |

I consider myself fortunate that I was always able to work the jamming free without excessive force. But the problem had to be fixed. Rob Reilly's document and extensive photos and
drawings gave me the confidence to dismantle and rebuild my gearbox
myself. I'd had previous experience with a Riley Pathfinder gearbox
rebuild, and with rebuilding an Alfa Romeo Giulia gearbox that had not been assembled correctly and locked out fifth gear. 2. A suggested way to deform the stop rivet shank after the rivet has been sized and then inserted in the second gear synchro sleeve. |
