Hi....
I removed the Clutch case on my Hybrid today.. How much movement should there be on the clutch basket when moving it by hand?

Approximately 4mm IIRC

Hi Mark Back lash and the rotational play you mention are 2 different things. Backlash - as I understand it - is the clearance between the teeth on the primary drive gears. The correct backlash stops them jamming and helps oil to penetrate between the gear teeth. The rotational play you mention is due to he rubber discs that sit in the back of the clutch basket;  20170217_192833_zps3pdsbx9e by David Miller, on Flickr You can rotate the basket slightly without the gear on the back moving. Worn, compressed rubbers will allow more movement. I don't know what the acceptable amount of rotation is, but I've read 4-6 mm is acceptable ? When I rebuilt my engines I fitted billet clutch baskets, and I wasn't gonna use 30 odd year old rubbers, so I replaced with new Wiseco rubbers - no rotational play now but no obvious side effects. If your basket tangs ae in good nic and not badly worn, and there are no other clutch problems it's probably fine. If you intend to replace a knacked basket, then I would change the rubbers at the same time  Dusty |

Thanks dusty.... My terminology is not up to speed yet.. Glad you knew what i meant anyway... my clutch basket does have 'some' play/slop in it.. 3-5mm... I am going to see how things go with the other parts first then i will be onto the motor...
Thanks...

No problem mate😉
I think 3 -5 mm is probably fairly standard unless the basket has been rebuilt at some point.
Dusty😁

4 to 6mm is factory rotational setup. Those rubber pucks (when oem :-) are of dissimilar size for that reason.
IMO many setups were 'cured' for no valid reason beyond the perception of a problem
Aftermarket pucks are typically of same size.. and unsurprisingly; don't live near as long as oems do.

Suppose but that's only a Photo not revealing much beyond that it is indeed a fitted clutch assly.
Suggest that if not already? Fit the Larger Yama friction plates.. 30% ~ increase in friction surface deals well with uprated horsepower.

Looks like too much play to me Carl +1...seen worse, but whilst it pieces I’d still pop some in... Gav |

Bare, you really do offer your advice far too often without realising what people are really questioning. I can sort of understand why you missed the fact a video was posted, but you assumed the poster was in error for posting a photo? Additionally, what makes you think he needs an updated clutch? Do you know they are using an updated engine that would benefit this? On a standard engine an uprated clutch has no benefit. Jon |
