'J' Type Overdrive oil pressure testing

[rvwp]

Hi Guys,

Having completed the rebuild of an 'J' type overdrive now mounted to the gearbox on the bench, I need to set up a power drive to the output shaft and check its operation before fitting to my 4A.

Whilst the overdrive may function during this test, I would also like to check the oil pressure. However, a pressure gauge has to be connected to the test point to do this.

Before committing to purchase a pretty expensive adapted gauge available from ODS Ltd and others, for a one of use, I was wondering if anybody had been down this route and   had such a gauge that they would hire me rather buy one.

Thanks 

Rich

Did you read this? https://static1.squarespace.com/static/5c6dec53b10f25d4edf0b3f7/t/5d019676f90de40001aae0a2/1560385143542/J+Type+Overdrive+Part+IV.pdf

Suggests using a LH rear brake hose from a TR4A-6 adapted to the gauge.

Then talk to this forum member.

Yes Peter, used Buckeyed triumph as a guide when rebuilding the overdrive.

Problem is I don't have an old rear hose to modify or a gauge of the correct range! To buy both of these would be more expensive than getting the proper item from ORS.

Thanks

Does the J type, use the same as the A Type, I know D types are different.

Hi John,

I'm guessing not as ORS Ltd quote different part numbers for the A and J pressure gauges. The difference is probably the pressure point plug thread.
