Falco 58 front forks

Post  Royston on Mon Oct 14, 2013 8:12 am

Hi all ,I have noticed that when I removed front wheel for refurbishment that the right hand lower fork had some play in it so I want to replace the bushes, so how easy is this for a novice such as myself and where can I obtain them from. Roy:cry:

It's a right old game. If it ain't too bad, leave it alone. There are two bushes in each leg which have to line reamed (the club has a 30 inch reamer). But getting the top bush in & out is not for the novice. The fork legs wear also, so how do they look? Might you get away with their replacement? Bushes would have to be custom made. Fork legs also require a lot of work to replace.

FORK BUSHES

Post  piston 197 on Mon Oct 14, 2013 3:19 pm

Back about 10 years ago when I was working in engineering and had access to machinery I reconditioned these forks for myself and other members ( did about a dozen sets,
I used to replace the tube with 1.250" hydraulic tube, if you turn the weld off the bottom of the slider about 1/2" above the bottom lug the tubes can be removed from the bottom casting. By using oversized tube it is possible to re-use the old bushes if not too worn and ream them out bigger with the inline tool ( currently with a member in Hertfordshire)I used to make new bushes out of whale brand Tufnol, they are made about .005" undersize and then reamed in situ
Easy enough job it you have the equipment, but not a home job, it is always the bottom bush that is worn the most,

Fork bushes

Post  myquest on Tue Oct 15, 2013 8:28 am

Somewhere in these archives is a write-up & photos of how I replaced my Falcon 81's stanchion bushes with Oilite units in April 2011.
Not a quick job, as they require turning & reaming to fit.The stock bushes were obtained from Simply Bearings Ltd.
Prior to this, I lightly honed the outer fork bores to ease ridges and/or scores.

Mike , the item will be of no relevance, totally different fork bush set up on the 58 to the 81, the 58 uses tufnol bushes held in with oil nipples and press fit in the upper fork while the bottom slider slides up the inside of them .The 81 uses soldered on bronze bushes on the upper portion while the lower sliders slide over the outside of these bushes. different bushes different material and different action and method of fixing.

Falcon forks

Ah - well done, John - I wondered who'd be first to spot that...
Apologies, to all. I didn't read the original post properly. More haste, less speed.

I'll get me coat...
