Oil Filler Cap & Insert

[peterb]

I am looking for an answer from someone who has had similar difficulties and resolved them...

My aftermarket oil fill cap threads itself into a slip-fit insert that has a single '0' ring. The insert is now spinning freely after almost 4-years of service without problems.

I took the valve cover off; removed the insert and cleaned everything up. The insert has 2 set-screws that are a bit below the lip of the hole and are thus not really grabbing onto anything well.

I am thinking of trying to replace the '0' ring and use a 'multi-metal epoxy' to try to keep the insert firmly seated so the cap can be unscrewed.

Does this sound feasible? Is there a better solution? Thanks.

As the adapter functioned properly for four years and now is turning, a new o-ring may fix the problem. The old is probably sacked a bit letting the adapter sit lower in the hole.
In addition O-rings come in various thicknesses for each diameter. A thicker ring may lift the adapter allowing the set screws to engage the cover.
A good auto supply house will have an assortment to choose from. They're cheap, it will cost little to experiment.
Good luck

I put the Wunderlich chrome filler plug on. It uses an allen key to put it on and off. The insert decided to pull out one day and I cleaned up the O ring and put it back in. No problems since.

I did run across another filler plug from another manufacturer that requires the valve cover to come off and the new seat is retained with set screws from the inside. This might be a better way to go than adhesive. I'm trying to remember who made this one.

just putting in my two cents.

I have one of these on my RS. It works as advertised and doesn't leak but....

The two set screws do not really hold the insert real securely. If I over tighten the cap, the insert will move. When removing the cap, I usually apply a slight "rap" to the hex key to prevent the insert from rotating with the cap.

Satisfied but not overly impressed.

I had same problem but only when the dealer did the service and tighted the plug with a wrench. I just tighten the filler cap with the hand tool they provide with the kit until I feel the cap "bottom out" on the seat. The O-ring compresses a little bit and maintains tension in the connection - i've never had it come loose and when doing this I've never had the seat rotate when undoing the plug.

It is something these days, to have a truely genuine resolution to a problem that seems to come from nowhere. All I did for several years was open and close the after-market oil filler cap - during oil changes or top-ups.

Eventually, tho, the insert started turning for some unknown reason - the set screws were tight! After several people suggested possible solutions [silcone; bearing retainer compound; multi-metal epoxy - all for setting the insert], I eventually located the original invoice and e-mailed and called the folks who made the after-market unit.

Well, let me tell you, Tricia at Moto-Techniques in TX is SUPER!! She not only assisted me as best anyone could, she stated the company NEVER wants anyone to have a problem with their [USA made :usa ] products, and she sent an installation jig to assist in installing the replacement insert.

Check them out for your needs. Moto-Techniques is tops in my book!! http://www.moto-techniques.com/ :wow
