Oil Filter O ring

Post by Martin.S »

I've been searching but can't find the dimensions for the oil filter sealing ring 042846 as the club doesn't stock it- does anyone know?

Nope because they are that rare I suspect not many have ever seen one. However you can measure the tunnel and the filter length and come to calculated guess. It wasn't an o-ring by the way it is a rubber washer.

I know where there is one but I doubt Shifter will want to strip the Model 8 just to measure it.

Ok, if anybody has one can they measure it so the club can have some made.
Or if any one has seen one(Shifter!) how about taking a guess to what the dimensions could be so we can get an idea of what it should look like. :)

Measuring up - the filter is some 1/4" shorter than the tunnel - are you all running around with the oil by passing the filter due to this missing seal?

Other than Shifter I suspect the answer is yes! If you can find a suitable flat washer or even a fat O ring that will work we could list it as Pt No 042846 Ring sealing oil filter.

I'm still looking for NOS but failing that it wouldn't be too difficult to make some if only their thickness was known.
Something like Neoprene could be used - it can be sourced in solid sheets and in a foam form.
A hole cutter could be used to cut the O/D and a Dremmel could trim the I/D - The O/D being a tad under the tunnel diameter and the inner big enough that when compressed doesn't obscure the pump port - its just the thickness dimension we need to know. For the mesh filters I suppose the thickness wouldn't matter so much as the spring will compensate
I'm thinking that the Neoprene sticky backed foam might be good as it would compress quite easily - what are your thoughts?

P.S - just came across this - https://www.rhnuttall.co.uk/washers/neo ... e-washers/
