Title: Rubber fuel tank buffer rubber struggle !
Post by: Stephen Foster on 30.09. 2012 19:50
Struggling fitting new grommets into swinging arm frame !

Any suggestions please ?
They just dont seem to want to enter the holes either side of the top frame rail !

I would first check that they are the correct size for the holes, many after market parts don't fit. Otherwise try coating them with washing up liquid first.

Hi Stephen,

Vaseline works good also, and it dries away completely afterwards

(and now you're gonna see the jokes come in......!)

both the above are good also after lubricating in either above ways position the buffers and squeeze them in together with a clamp across both of them.
even originals were tight

 Don't forget to take your boots off when you go to the bedroom for the vaso.
Sorry, morris knew I would  ;)
I use a lanoline spray for such things.
Cheers

I'm not completely sure if my 2.5 gallon tank came off an A65 Catalina or if it was from an A10 Scrambler, but I am rather sure it was not stock with my bike, a registered '55 with a replacement '60 frame. What I found after fitting the bumpers was that they were definately too wide to fit in the tunnel. I ended up shaving away the excess thickness with one of those long razor-knife blades where you break off the end to get a sharp edge. Not rocket science, but I thought it wa clever at the time.

Depends on what you're going to the bedroom for, Muskrat. In circles where vaseline is popular, they love a bit of leather gear too (so I heard...) *whistle*

I had the same problem. Solved it the same way. You sometimes need to cut some corners to get somewhere.... (or some rubber in this case)

spraying the rubbers with silicone spray makes fitting and removal of the tank easier.

Stephen ,I use washing up liguid ,just a spot works well and doesn't damage the rubber, they used to use it for fitting the old style rubber windscreens with a string etc.I fitted my tank rubbers only last week using this ,hope you get it done regards BobH

Rubber grease works well but is a bugger to get off.
Rubbers lubricant ( as bought from a chemist ) is even better and washes off with water but might take a bit of explaining *roll*

Some washing up liquid has a surprising amount of salt in it & can cause unwanted corrosion.
