Triumph Overdrive Speedo Angle Drive 120694 Premium. High quality Smiths style right angle gearbox drive fitted to all Overdrive models factory part number 120694. This is the best made angle drive available. European made fits and functions properly. Many inferior reproductions last only a short time either wearing out teeth or even exploding due to improper alignment.
Sports and Classics not only sells parts but uses the very best parts available for our restorations. Part is fitted to A type and J type overdrives on the following TVR and Triumph models listed below. Part number 120694.
IMPORTANT Unit must be lightly greased prior to installation do not use oil on drives or cables. Smiths recommends Castrol LM grease ie lithium based or Esso 119. Important do not over tighten cable. Some cables internal core drives are too long and cause damage to speedo from excess pressure.
Finally some experts believe a copper spacing washer is required when fitting a new angle drive. Others claim no washer is required on Triumph models. The bulletin in question was issued by BMC for Austin Healey models with A Type overdrive. We have not found a similar bulletin for Triumph models. It should be considered on A Type overdrives. You may request this copper washer when ordering ( 3H350) and we will supply at no charge.
