Bottom filter bolt

The thread in the case where the bottom filter bolt (Allen head) goes, seems to be going south. I have to retap the threaded hole every time I replace the oil filter, because I feel a lot of resistance when I try to thread the bolt in the hole. Anoyne tried to replace the tree bolts that hold the cover with threaded studs and then use some spring washers and nuts to hold the filter cover ?

That sounds like a good idea. Threadlock the studs in and use spring washers for the nuts. :thumbsup:

I agree with your concept just put in a small length of all thread cut to the correct length and red loctite her in. Then the filter cover can be held on with a nylon lock nut and washer. :thumbsup:

Awesome idea. I just repaired the allen bolt on my fiancee's 250F, I used Permatex's stripped bolt repair kit. If I would have thought about the stud thing I might have tried that instead.

great idea. will keep it in mind

The only drawback I see is that oil may not drain well from the filter cavity, leaving the potential for a messy oil change.

:thumbsup: How about you install a thread insert Helcoil and a new bolt as long as you can get the Tap in there and still turn it you should be good. You can even count the threads so you don't run the insert in too deep. One of these day you are going to have to strap on the "Big Balls" and fix it right. The tap you are cleaning the threads with now is just taking more and more metal out of the hole. :thumbsup:

That's the problem. When you use that bottom hole for a drain all the dirt and crude drains out the hole and some of it gets in the threads and dada over time the threads get funked up.

When I change the oil filter on my bike I lay the bike over to the left so no oil drains out the bottom filter hole.
