2007,2008,2009 Derby cover

[fasteddiej]

I am looking for someone that can put a plug in the derby cover so oil can be added without pulling the derby cover. Has any one herd of this?

[fxstdavew]

No I don't know anyone but I would think any machine could help. with that said you can't tell if you need to add any oil unless you pull the cover so I don't see why it's needed.

[randyman]

I believe Baker makes one.

The cover is probably too thin to accept a threaded plug.
I don't suppose you could pump oil in through the drain plug because of pressure build up could you?

I have one that goes on the adjuster inspection cover. Has a filler like an oil tank.

[EagleFTE]

How do you know if it is filled to the proper level?  Or do you just put in the spec'd amount in onces?

Never thought much about it before, but why not just drill one of the cover screws all the way through.   It would be a small hole but after all you don't have that much fluid in there to replace anyway.   You would have to use sealant on the screw to prevent leakage.
