Volvo Penta DIY outdrive pressure tester-gctid394314

[Guest]

Hey all,

I've made a pressure tester for my outdrive, well 90% of one. I am unable to find the piece or pieces necessary to mate to the top and bottom plugs. I do know that the plugs are 3/8 -16. I'm trying to find a nipple that size but no one seems to make that particular part.

Any ideas on where to go next or what to do?

You'll be leaving the drain plug installed, and will use the dip stick port for the gauge and check valve.

The threads are standard 3/8" NC.

Oil must be drained for the pressure leak-down test. The vacuum leak-down test doesn't care.

Contact Tom Green, and ask if he'll sell you just the tester unit, gauge and check valve.

Here is one of Tom's testers.

I've used Toms kit recently, works great. Good to know your seals are working.
