A couple of spare hours, and with my little helper to hand, was enough to get the accelerator rod mechanism cleaned up and back in. The small mount (circled in red) that fixes to the brake and clutch pedal mounting had completely seized solid. It was so solidily stuck that when I initially tried to press the ‘gas’ pedal it would flex the firewall/bulkhead rather than pivot in its mounting. It took a vice, several soaks of WD40 and a week to free off and enable the small mount to rotate around the rod, freely.
The rod was treated to a clean up by wire brush and two grades of wet and dry then a coating of sprayed on grease to keep things lubricated and clean-ish. It was the first time this piece of the car had ever been removed in 46 years, evidence being the over spray on the special rubber grommet on the firewall, which will need replacing.
Installation was reverse of the removal, just less of the cursing as the youngster was present. The heater proved to be equally tricky to get back in as it was quite heavy to lever upwards and be aligned with it’s mounting holes for the bolts to go in. Next step, will be the re-install of the clutch and brake pedals.
