Hello gentlemen,
I'm looking for the fork oil seals for a Matchless 1947 G3L.
In my last ride of 50km I got oil all over my t-shirt from the forks, so I can't ride this bike anymore without the proper seal.
The thing is I bought a set of seals but I've made a mistake, I got the wrong ones or they're for another part of the forks (see pic).
I'm not sure how they look 'cause I got this bike without them.

So if anybody could tell me which ones are the right seals that would be great.

Thanks

First off, I am FAR from an expert about these bikes!

That seal in your hand, in the third pic, is for the slider. NOT the top fastening bolt for each fork leg. If that top nut/bolt in your fingers in the second pic is where you are looking for a seal?
I do not have any kind of seal at the top of either of my fork legs.

Other than the red fiber washers on the drain screws and dampener rod assembly fixing bolt [ if so equipped! ], I don't know of any other seals...

Makes me want to ask you a question..... Just how much oil are you putting in each fork, after you have drained it?

You will have to drain the oil out the forks before refilling them, otherwise you will overfill them. They should have 6 fluid oz (refill) or 6-1/2 if filled after strip and clean. The top bolts have a groove for an o-ring, but oil shouldn't get there normally. I use 20W50 in the forks.

There should be a steel washer under the top nut on your forks.
Part number 40-G12M-FF190 Washer, plain, fork inner tube top bolt.

Without it, your forks may well leak oil, although it does sound they may have too much oil ?

Thanks guys,
I followed the manual when filling the forks with oil, I don't remember the quantity but I added SAE 20 oil, maybe it's too thin.
It does have the metal washer under the top nut.

I'm not sure how oil can get there, it will have to get too much air pressure to force the oil out.

I'll empty the forks and put something more like SAE 50, Also I'll add that o-ring around the nut, although I don't see it in any manual.

Your picture doesn't show the metal washer.
50 weight oil will be too thick, 20 sounds about right.

Its most likely to be the quantity that is the culprit,
too much and some has to get out somewhere,
oil doesn't compress
