Hardy - Chief Dev. Engineer}3/JH.13.4.40. 10.B.V. Clutch Throwout Bearing. This is to confirm that we have asked you to fit one of the standard B.V. type throwout bearings and housings to the above chassis in place of the existing early type which has failed. Also that we have asked you to remove 0.100 from the front end of the trunnion housing GB.4084 in order to give the bijur oil a better chance of reaching the ball bearing.
