Hi new addition Swing arm B33 please what is this clutch and how do I remove this part , do I need a puller for the centre
Here's the friction plate centre
Looks like a Suzuki type clutch conversion for the bsa
Cheers Roy , it's got a alloy gear wheel but does the original centre just pull off the gearbox shaft
Hi people could I put an original clutch back on has anyone got one please
And does the original clutch splined collar just pull off as it seems stuck on
The vast majority of people nowadays are junking the original 6-spring clutch as they are all getting a bit tired now and can be fiddly to set up properly. Having s as I'd that I have two machines where they are ok particularly with decent gearbox.
The Pearson Suzuki or NEB are exotic mods.
Triumph 3 or 4 spring conversions are popular and less expensive (still not cheap).
What is wrong with the one you have now?
I am worried about the alloy gear wheel and it's durability can you tell me what this pipe is for coming out of the engine casing please LHS btw
Plus I guess the chain is not as original I would like to replace when I check it's bend over full length it looks worn
Hi Neil, is this a Pearson clutch ?

It looks like you have the 4 spring clutch hub on your conversion, so I believe part no. 61-1912 (Clutch Hub Puller) would be required as the mainshaft is tapered along with being keyed.

The pipes in your picture are (upper shiny one) oil return from cylinder head and lower one with rubber pipe attached is engine breather. You must have an early engine there, because on later B engines, the breather was on the outer timing cover.
Hi , fitting belt conversion , selling the clutch if anyone wants it
Any ideas about the engine breather pipe as it drops oil all the time even when the bike isn't running but only when the bike is on the side stand please help lol
Isn't that brass feed used as an oiler for the rear chain?
What does your timing cover look correct?
Whose belt drive are you using? Is it new and spec'd for your machine?
I hear mixed reviews, have contemplated but not tried. Not sure if it is a Pearson as I've not seen one fully stripped down before.
If it's a Pearson let me know , I can add more photos if people are interested
Genuinely speaking,the clutch you have are very good and work exceptionally well , alloy sprocket is fine as Long as the sprockets and chain is running perfectly in line if not it will ware out spkt in very quick time ,
( a great deal of racing rear wheel sprockets are alloy and last hell of a long time )
The clutch Center on your bike looks like a std bsa 4 spring clutch type ,
The breather pipe on the drive side was ditched for that reason ,( oil) it went to timing cover ,that alone had at least 3x modifications to help keep oil in and breath at same time ,it all good fun if you don't weaken 😊
Hi Roy can you give advice on this breather as on the side stand it constantly drips oil onto the floor , say one drip every 30mins , is there a way of changing the breathing IE updating
Sam if poss post up a photo of your timing cover ,let's see what one you have , is your bike up and running ,
If not it's possibly crankcase has wet sumped and oil level is up close to main bearing and leaking past ,as even as standard there is no oil seal that side ,only the distance piece behind the engine sprocket being a close fit to crankcase to stop oil passing by , there are few options , if you are stripping engine completely to help this situation, fit a sealed main bearing (bearing number 6205 RS ) or/ and machine case and fit garter seal ,
Cheers for the help , might rebuild next year
An article I remember reading a while ago. Trevor is quite up on these things too (afraid I am too sketchy on specifics) so it is good that Roy is sharing.
