speedo drive

[jeff-d]

hi, can anyone tell me the spanner size for the speedometer drive housing nut its a brass nut not the plastic one, just taken the car (A 1959 morris minor with 948 gearbox )out on a test run after more than 2 years of fixing it up to a good standard and found that the speedo is not working i attached a drill at the gearbox side of the speedo cable and the speedo is working, so the problem must be on the pinion and bush but i am having a job finding a tool that fits the large nut so what do you use a socket a spanner or a ring spanner and what size would it be, also when i took the old pinion and bush speedometer drive housing out it had a plastic nut head and i replaced it with a brass housing i wonder if that would of made a difference or is there different ones for different models cheers
