Speedo Right Angle Drive - Triumph TR4-6 GT6 Vitesse MGB. 120694

Speedo Right Angle Drive - Triumph TR4-6  GT6  Vitesse MGB.   120694

This speedometer angle drive was fitted to many British cars where there was insufficient room to run the speedometer cable directly into the gearbox. The original angle drives quickly developed a reputation for being prone to failure.

This resulted in a thorough investigation that in the end resulted in the Technical Service Bulletin (TSB) of February 29, 1968.

The TSB explains that the 3H550 ‘washer-adaptor to gearbox’ must be fitted with the angle drive. If the washer is left out the end load on the angle drive will be excessive and it will fail. 

Recommend to replace washer 538532  at same time.
