Diy 25/30 Conversion

[Ruthr33]

Hate starting new topics every question I have so I'll try to keep them here.

Got my second hand rb30 on a engine stand. Tapped and pulled the crank gear off. Can I buy a a rb25 one to replace it or does it have to be rb30?

Pulled the oil pump of to shim the spring 2mm and replace the front seal. I got a bit excited and pulled the pump apart to check for any wearing. I'll clean it up and put back togeather. Do the screws have a torque setting and do they have to be lock tighted?

20/25/26/30 same crank sprocket.

Do the oil pump screws up tight AF and use loctite.

The RB20/25/30 crank gears are all the same, the RB26 crank gear is different.

Torque specs for the screws are 3.7-5.0 Nm and i would recommend using red loctite on the screws.
