Question to anyone who has installed the HD oil cooler. What size allen key did you have to use to screw in the oil filter threaded adapter. I cant seen to find an allen key to fit right.
Any ideas!
Thanks HiTech

 

Allen key is a large one..I did a search on the forum and found that the head of a 1/4" bolt was perfect. double nutted the threads and was able to use a socket on it.

 

7/16"

 

It takes a 7/16. I did the bolt with two nuts trick to put it on but when I needed to remove it (leaking oil) that trick did not work. It took a bit of searching but I found one.

It the one at the far left of the allen socket rack!

 

No the allen socket on the far left would the 5/8 allen socket you use on Mercury out drives wouldn't it??

 

Use a 7/16 all thread coupler to tighten it.

 

I've looked for one of these everywhere (Lowe's, Home Depot, Ace) and couldn't find one. They seemed to have every OD except 7/16". Where did you find yours?

 

If you have the one I bought (26155-09) it uses an allen wrench size is 11 mm

 

Order it from SEARS online and pick up at nearest store...
