MG TD TF 1500 - Speedo pinion oil leak to cable

I have taken my TD speedo out for rebuild and the rebuilder notes there is oil in the unit. A review of the Moss catalogue and the WSM does not show any part for a seal or O ring at the speedo pinion. How does one correct an oil leak which travels up the cable to the speedo head?

John - You can send the speedo pinion w/the surround to From The Frame Up (http://www.fromtheframeup.com/)and they will modify it to accept an 'O' ring. Cheers - Dave

I did this mod from FTFU about 4 years ago. I had a persistent leak from the pinion that made a mess on the right underside of my car. Now, does not leak a drop. Worth the money.

Thanks both for your suggestion and endorsement. I have pulled the pinion and it is on its way to FTFU. Had to chisel away part of my 38 year old homemade floor board to get clearance to get it out but the task is completed.

I have just fitted the FTFU speedo pinion and nary a drop of oil. This was great advice from the wise men on this site. Great service from the company as well. Now I have to pull the speedo apart to clean out all the gearbox oil which has migrated into it!!

What ever you do dont use a solvent to wash out the speedo you will watch all the roller numerals disappear if you do.

I am reactivating this thread to ask a question. I just got my modified speedometer pinion back from FTFU and it did not come with an O-ring installed. Can someone tell me what size O-ring you used.

Thanks

The o ring is inside the assembly. No need to add anything. Call FTFU on Monday.
