Thread: Weiand oil change

Tweet

Ay way to drain oil on Weiand supercharger without taking it off. Never done one before. How often would it need changing. Nothing on their site. Thanks

Do you have the Pro-street model with the sight glass on the front? If so, the oil should be at the bottom of the sight glass. It fills from a plug on the top of the unit. The rear bearings are sealed and do not require any maintenance.

It is a pdf with all the good info you'll need..

Good Luck,

I think it's either the 122 or 124. I can't find any markings on it that identify the model. There is a black nut on the top right front with a screwdriver slit in it that has a dip stick attached. About half way up on the front and back toward the center there are "bungs" (like differential). I know the back and front have separate reservoirs and you remove the back bung to check the rear reservoir oil. I know the oil is supposed to be level with the back hole. It does not have a dip stick in the back. There is no sight glass on the unit. Don't see any drain plugs. It's a lot like sex, a lot of confusion and I want to make sure I'm doing it right.
