BW 35 check valve

[john gosnell]

Has anybody info on fitting a check valve on the BW 35 gear box to stop drain back, I understand that one can be fitted to the return pipe on the oil cooler if so what type/part number should be used

Regards John

The part number is RTC0035, but they are no longer available. I've only come across one fitted to all the boxes I've dismantled in the last 10 years or so.

Is there an alternative valve and if so where would it have been fitted

The only other valve is the ball and spring in the valve block, which doesn't have a very good track record either.
