Recommended Posts

forgive me for this simple question but the clutch on my TY seems really heavy,i have fitted a all Yamaha O/E parts as follows

clutch cable

plates

steels

springs

I had a tang on the basket repaired and refitted.

in the manual it says back the cable off

remove LH engine cover

loosen adj nut and screw in adj screw all way in ,take up slack with middle cable adj the wind adj screw out till it stops the back of a further 1/8 turn and lock the nut,take up remaining slack with middle cable adj and adj on clutch lever bracket.

problem is nearly all if not all adj on cable is taken u and clutch still feels v heavy,what am i doing wrong?

for the adjustment problem:

you didn't mention the ball between the pushrod and the mushroom rod. They can fall out unnoticed while you work on the clutch

 

for the heavy action:

inspect the camshaft for wear where the rod end rubs

you might have been sold springs that fit, but are stiffer than TY175 springs. A lot of Yamaha models use similar but stiffer springs. Try the old springs

lube the cable

 

Because you have a combination of heavy action and lack of adjustment, it is also possible that you have too much plate stack height. Compare the thickness and quantity of the old plates with the new plates

i'm messing with the same issue. Today, I started wondering if the PO had lost that ball. My clutch arm rotates about 30 degrees w/o any noticable effect. I have everything adjusted to get the most out of the lever travel, and the clutch still drags.

there's no freeplay left.

i was able to buy a nos clutch arm/cam on ebay for $14 yesterday which i may throw in just to see what happens.i Have that same manual, and the adjustment instructions threw me at first. I had to look at a junk motor to figure out what hey were talking about. 

 

can anyone tell me if the long clutch rod can wear?

Bent, i've seen, but I think they're hardened? I figured i would measure mine to be sure it was the correct length, but can't find a spec for it anywhere.

if anyone knows what size that ball is, that might be good to know as well.

 

sorry if i shanghaied the OP

According to Partzilla's site the ball size is 3/16.

I replaced the pushrod in my 250 when I rebuilt it as there was some wear on the end & a new 1 was cheap. I can't tell you what else uses the same pushrod to give you an idea of cost as the part description comes up as the ball as well

Ok I will check for the ball bearing ad I did the job with the bike laying on it'd side so maybe if it's not there I will get one . Unfortunately I don't have the parts I replaced they were in such bad condition and as I bought a complete clutch from a TY specialist and it was all yamaha wrapped I didn't consider it wouldn't be correct. I guess I could slack the springs off and see if it's them . without running the bike just to see if springs are too hard. I will check the adjuster for wear. Annoying as I'm selling it and just trying to get it as it should be
