Clutch plates

[Pauarc]

When you fit keyed washer should it have be loose on shaft I have douts the fin washer was there I think I am going to take the clutch out to find out if it’s there

Just when for a test run to try clutch adjustment a bit better cold but worse when hot 🥵 could it be the oil getting to sticky when hot in the 70s I used 20/50? Any thoughts it has putoline s4 mineral oil 10w40 in now

The oil gets thinner when hot, would be unusual to have a change in that to make it worse as ordinarily the clutch works more consistently when warmed.

It may be wise to remove, inspect and quantify the thrust washers etc to establish if anything is out of order there as characteristics seem odd.

Before any removal it would be worth pulling and pushing the clutch assembly in and out in order to assess if there's any/much end float on there. This is what the thrust washers etc are trying to control to give repeatability in clutch operation.

Now I have decided that I’m going to remove clutch and see if I can find something I will see if there’s any end float

The thin thrust washer is between the bearing and the basket.

It just goes on shaft first before putting the clutch basket on, located between back of clutch and bearing.

Don't believe a manual. It is number 18 in this link >>> https://www.cmsnl.com/honda-cb750k2-four-england_model14363/partslist/E18.html

I have added some pictures I must be missing something I have a 25mm shim

I am not sure what the washer is in picture number 3 you have posted. Can you post a picture of that washer on its own and not on the shaft.

I have just fitted a shaft to a set of crank cases and the thrust washer i was on about is the other side of the bearing so, forget about that one as, you will not even see if on a clutch change

There is also this fitted between the clutch basket and the bearing.

Shim washer

I am not sure were this shim washer has come from. Once everything is in you have a bevelled washer with outside stamped on it, then the clutch locking washer and then the locking nut.
