Setting up the distributer on my rebuilt 1275 engine I had bought new plug wires. The screws that hold the wires in the cap were frozen in place and I sheared the head off one of the screws. No problem I thought as I has a spare cap from my TR3A rebuild.
I had the distributer set in the correct location, fitted the cap and cut the wires to length. I was not really happy with the orientation of the cap to the engine so I thought I must have the drive gear off by a tooth. Removed the distributer and support then tried to get the drive gear out. On the TR3A it is a simple matter pulling up and turning it to the new location. As I started to pull it out I noticed it was getting crooked then it slipped into the sump. Had nor realized there was a thread at the bottom of the drive to assist the removal of the gear.
Sump came off again gear was reset and then I realized that the MG distributer cap and the TR cap are not clocked the same. There is a 90 degree difference in the caps.
1. The MG and Triumph caps are different.
2. Screw a 5/16" bolt into the distributer gear if you are pulling it out while you have the sump in position.
