Oil filter chewed up the case

[LOUD MOUSE]

What I think.
Smooth the surface of the case.
Install a totally different filter. (good one of course)
Install only one washer (the wider one of the 2) at the cover end of the shaft/filter and allow the steel bearing surface of the filter to do as HONDA intended. (just contact the case)
Just what I recommend. ..................lm

I am still pondering what to do. I now see that there is a steel collar in the filter and presumably one in the case but it’s badly damaged. I am thinking of just touching the surface on the case with a piloted counter bore to clean up the surface and put a good oil filter assembly back in. If I can get case surface cleaned up then I would be ok without the washer epoxied to the case.

Thanks LM. That’s what I’ll do. I’ll take a few pics of the process of cleaning up the case and the post the final result.

I await your pic. ............lm

I McGivered up a tool using the oil filter shaft and a high speed cutting tool I had and faced the oil filter shaft boss. I had to take about .030 before it would clean up nice. I am feeling good about how it came out. Time to put it back together

will you need to now use a washer to shim up the extra space? if so, on inside or outside and what about chain alingment?


Thanks for sharing, and you get this months official mc guyver award..

Hi,

I encountered the same issue, for another reason. The oil filter chain alignment is adjustable by two (three) ways :

1) the mentioned and suggested method, shimming by washers.
2) relocate the position of the sprocket on the filter
3) relocate the position on the crank sprocket.

Nr 3, is difficult but possible (shimming the gear on the crank), Nr. 1 as mentioned, is a gentle solution, easy to accomplish. Nr.2 is also a nice way to do it, and if you have a fridge and a press, not very difficult to do.

I like your creativity for cutting the surface, nice job.

Thanks for everyone’s time on this,

I was considering shimming but think it’s not needed. There is quite a bit of clearance in the stock setup and I doubt a little more will be a problem. Too little clearance would be a problem and is what I think led to the problem in the first place. Also the thrust must be generally toward the clutch cover given the placement of the factory thrust washer so there shouldn’t be a need for a thrust washer next to the case. While it probably wouldn’t hurt if I got the clearance right I am paranoid about not getting it right and having problems again. I think the sprockets align themselves as long as there isn’t something holding them out of alignment. I’ll put it back together with a good filter and see how it goes. Now I need to figure out how to get an inspection mirror in there so I can keep an eye on it.
