Hi, im new and trying to figure out how the heck to loosen that slotted set screw in the crankcase to get to the secondary oil filter! I dont have any slotted drivers that big.
Thanks

 

They actually make a tool for that. It fits in the slot and has a hex nut on the end so you can use a socket or a wrench.

When I finally got mine out a replaced it with a different style that has a hex on the top.

 

do you know what its called or where to find it please?

 

here ya go:

These are the first ones I came across. Make sure they are for your EVO before you order

 

it's called a drag link socket
these 2 are on ebay used for
$3.99

 

Yup, a drag link socket. I made mine for free.

 

What makes it EVO specific? I would think they'd fit any cone motor - Shovelhead or EVO.

 

I would think that the tool would be, but I'm unsure of the threads on the cap.

 

I'll have to check it out. Thanks for bringing that up.

 

Be very careful putting the new one in. You can strip it very easily. Depending on the condition of your tappet screen, you might wanna replace it and the spring. Brake cleaner usual cleans it up nicely.
