Rd125lc Mk3 1GU gearbox question

[flagman1971]

Hello my 1GU sometimes hard to get neutral. Does anyone know (to help me source parts) are the gearbox components the same on mk1, 2 and 3 RD?
Also is the DT125 35E from 1986/7 the same gearbox as the mk3 RD125LC 1GU?
Any help or advice would be great. I don’t want to buy some DT bits that don’t fit

Did you fix this Henry?

If the engine has been rebuilt and the bearing on the gear drum changed, it can cause problems if not seated perfectly.
Many of the parts in this area go back to the MK1  DT and have 10V part numbers
