hi all,
      new to this,has the title states,when i tighten the nut on the clutch drum it locks with the basket,i’ve looked in the haynes manual and it says i should have a plain washer,bearing washer and another plain washer,which i am missing one plain washer,but even with the plain washer missing it’s like i don’t have enough room at the end of the shaft to put the locking tab on to safely engage with the splines,any help would greatly be appreciated.

Greetings from Tennessee  

thanks for the welcome

Have a look at the vin number on your engine and let us know what model we’re talking about.

On the CT1 there are a couple of thrust washers that go onto the clutch assembly first #18 and 19, often the back one slips down on assembly and stops the collar #17 seating fully on.
 

Yes, somewhat important to know what you have.  If it's a UK/Euro model, it could have a "CT" VIN and be a 1974 or 1975 model more equivalent to the 1974-75 US DT175 than than the earlier US CT Series.

If UK/Euro model, there is likely an asterisk at the beginning and end of the frame number.

hi
sorry for the late reply,the vin is,*ct1-311098*,it is missing a thrust washer assuming this is the right clutch,i will try to upload some pictures when i can figure how to do it,can anyone point me in the right direction to a diagram of the clutch and part numbers,thanks to this forum i’ve found out 74/75/76 clutches are not the same

forgot to mention it’s a uk bike

Check out post #2 from MarkT on this thread regarding UK VINs.

Best thing to do is to try and find an original parts list for your bike - fleabay is good for this, although you might find you end up buying one from mainland Europe. An original Yamaha service manual is a good investment as well.
