anyone know which type of molyslip grease to reassemble the front forks for an f-frame? is it right you coat the rubber?
copaslip, speed grease, red rubber grease, high load bearing grease,
machine tool and spindle, white marine grease?

[david james]

if anyone knows i would be grateful for an answer, hoping to get it back together this weekend!

thanks for that , i take it cv is constant velocity joint grease?; obviously not to be used near the rubber, i’ll use special rubber grease,
got the screwdriver from halfords no 2 philips by 250mm
for about five quid.as the screw came undone so easily i thought i’d carry on and do the whole thing

Do you know it has always puzzled me that black CV grease is not recommended on the rubber parts, when on a BMC car CV joint the parts are protected by a CV boot made of rubber, and does little or no harm ? These are always full of the stuff!

[david james]

that’s very true, on the old mini the rubber boot lasted longer than the joint!

Towards the bottom of the Bicyclehub page about fork renovation, nest to the picture of upturned yellow forks they say – “Use Molyslip or CV grease to lubricate the inside of the fork tube…. In my experience Molyslip does not affect the rubber, or deteriorate it. However, ordinary lithium grease may well swell and soften the rubber so do not use it. “

haven’t got the bottom bearing retainer off yet (waiting for c spanner) but i was under the impression if you lubricate the top bearing and bottom with whatever grease it cannot get on the rubber spring as it has it’s own “tube” ie separated. if this is wrong i’m more than happy to be corrected!

[david james]

looking at the official way of removing the bottom splined bearing retainer by putting a screwdriver blade in one of the grooves and belting it with a hammer didn’t appeal to me much so i got a jubilee clip (a good quality one) tightened it on the retainer as hard as possible (oil or lubricate the thread taking care not to get lubricant on the mating surfaces) ,then grip with a pair of water pump pliers or molegrips preferably with a rounded jaw.the threads actually help the pliers grip and mine came undone a treat.i would try this method first as buying a “c” spanner is not an easy task go into halfords and ask for one and you’re met with a blank stare, i went into a specialist toolshop and they didn’t have one, there are some on ebay but there’s no way of measuring which size you need.
