Hello, I am in the process of trying to remove a swinging arm splindle with no joy I am assuming it is frozen to the inner races within the needle bearings, I am guessing it is going to come down to some heating to free it.
Your experience would be appreciated.
Thanks,
M.
 
Hello.

  There is graphite easing oil called EAZITE or alernatively Plusgas  .. They beat the daylights out of WD40 as they have a much lower vecosity.. I think they are both based on ETHER so don't nod off when using....  Both are used on diesel marine engines here in the UK....

    Or nip to your local model shop and buy some plane fuel and mix a little graphite grease with it !

                    You heard it here FIRST

thrash the living snot out of it with the biggest hammer you can find & a sacrificial drift.  :D

Then FFS don't make the mistake we did & reassemble it with the same spacers & inners.
 
Timbo is quite right, PlusGas or Lusol, ignore WD40 or it's derivatives, it just aint up to the mark, but go gently with the big fuck off hammer, gentle but firm persuasion is the way to go, not brute force and fucking ignorance!.

Since there is a nut on both ends why not use one to pull it out?
remove both get 4 or 5 washers load up one end and and remove by tightening the nut.
( air gun would come in handy).... Might work??? :D

I had the same problem with my 79 triple. I think the previous owner had installed the needle bearings by driving them in which distorted the bearings and cages. The spindle was a very tight fit. When you install the new bearings best to use a threaded rod and carefully pull them into place.

Sorry Dennis dont understand how knackered bearings would stop the spindle coming out.

Sounds more like the bush has rusted on to the spindle.
The needle roller bearings and the spindle don't touch each other.
 
Why do you all think it has needle rollers? It's a 3C, they had phosphor bronze bushes didn't they?

Mine did when I bought it, but when the needle rollers became available as spare parts I installed them, and so did quite a few others according to the Stanco parts bloke in Melbourne.

Hi Dave and Grant, wasn't thinking clearly there sorry. It would be the bush that contacts the rollers. So it would be the spindle seized on the bush. On my bike the bearings had likely been driven in, distorting them so that the bushes had to be forced in. I assume they should be a sliding fit otherwise they would not serve much purpose would they? When I removed the swing arm the bushes were a very tight fit in the bearing so that the only rotational movement was between the spindle and the bush. I would assume that the spindle should turn freely in the bush and the bush should turn freely in the bearing. Is that how it goes?

Dennis,

The spindle might spin freely in the bush, but neither should spin at all when all is tightened.

The force applied to the nuts at either end should lock most of it rigid, leaving only the needle rollers to rotate around the stationary bush.
