Clutch Locking Washer - Cannot Align
« on: December 28, 2020, 05:45:00 PM »
I've just replaced the plates on my clutch. Everything was going great until I tightened the clutch centre castle nut. The torque settings I understand should be in the range 29 lb ft to 32.6 lb ft (CB400F).

However, I am unable to get any of the locking washer "tangs" to align. If I start at 29 lb ft and increase the torque in increments to 32.6 lb ft, non of the tangs will align.

I can get a tang to align at 26 lb ft and another at around 35 lb ft.

When I stripped the clutch down, the tangs were not aligned. The PO had just bent a tang upwards with half in the recess and half outside! So it appears they had set at a recommended torque setting and just bashed the hell out of a tang for a partial lock.

So my questions:

(1) are my torque settings correct for a CB400F (29 lb ft to 32.6 lb ft)?
(2) if correct, any ideas why I cannot get a single tang to align between 29 lb ft and 32.6 lb ft?
(3) can I (should I) use a lower (26 lb ft) or higher (35 lb ft) to facilitate alignment

Thanks

Dave

Go up to or beyond the 35 ftlb until the tabs align.
