AJS & Matchless Owners Club

Hello every one.
I have just bought a 61 G5 and I am keen to change the oil. I ha be removed the oil filter cap , and removed a long spring , filter cap and the shorter felt filter. I have ordered a long felt filter , short spring and cap for the non spring side. I am now. Puzzled by the lack of this cap when I pulled out my old filter. Is it likely to be stuck in there still ? Any tips for pulling it out ? I don’t want to assume it’s in there and sitting correctly and neither do I want to end up with 2 caps in there .
Any a£vice greatfully received
Thanks
John

Welcome, John.
If the cup didn't come out it's still there if it was already fitted, and they don't wear so I'd leave it there.

Have a look at pages 18 and 19 in the workshop manual here which suggests using long-nose pliers to remove the cup:

Having just done it this afternoon, use an old bicycle spoke with the end cut to make a hook, also useful to remove the oil pump if you ever need to. There should be a rubber washer that sits right at the end of the gallery, you should pull it out and replace it as it will have gone hard, a good torch will be a bonus here. More often than not though, there will be nothing left in there. You should have: a screw cap, a spring, a cap then the filter then a seating cap 042062 and a rubber washer. Unless you have the one piece filter in which case you will have the filter assembly and a rubber washer.

Thank you Red Gauntlet. I've just done the oil change on my Model 8 for the first time and made a guess about how the filter went back in, based on what I thought might make sense. I'm not sure whether it was installed correctly before or not but you have confirmed that I've got it right now. I feel it was as much by good luck as good judgement. At any rate, the oil is circulating nicely and the engine sounds better for it.
