Can anyone advise me on how to dismantle a Regina 6 speed block that I want to use for a rebuild. It is in great condition but feels really gritty when rotated.
On the back there is a plate with 3 notches which I assume unscrews - I could use a hammer and screwdriver but suspect there is a tool ( there usually is ! ).
Thanks

The plate doesn't unscrew.

Not a task I've ever undertaken, more fiddly than I have patience for.

Thanks gas
I had some advice from a friend to just run in some oil. It does run fine so I may do that and avoid a messy job.

I think the advice is to "flush" with WD and then when dry run some oil in.
Re: Regreasing a 6 speed block
if the bearings are loose it is worth removing the cover plate and adjusting the shims so that the bearing clearance isn't so slack, and sometimes to renew the ball bearings if they are in very bad condition but in general terms it isn't worth dismantling a freewheel just to lubricate it.
If you want to lubricate it, I'd suggest cleaning it (if necessary) and then lubricating it using an aerosol semi-fluid grease; this will penetrate whilst it still has the solvent in it, but once that has evaporated, it will leave a more persistent lubricant in the bearings.
By contrast oil simply runs out of a freewheel when it is first used.

Re: Regreasing a 6 speed block
As Sheldon says, if you do take one to bits, it's the front plate, not the back one, that unscrews. We used to take Regina ones to bits because you could replace the pawls and so on when they broke. Quite fun putting them back together - requires cotton thread to hold the pawls down so that you can reassemble the thing. Haven't done it for years. As above though, just lubricate assembled.

Can you recommend any semi-fluid grease products for this?
