Clutch Pressure Plate

[Blaster8821]

A week ago I blew out my clutches on my Blaster, I had ran them for about 6 hours total and then they started to slip again. I have done clutches on 3 other Blasters and have been successful so I know how to do them. When I took the cover off, I could smell the plates had been slipping. I bought a new set of clutches again and when I was reassembling it, I noticed that the push rod nut is sloppy in the clutch pressure plate like in the 2nd image. is this normal or should I get a new one clutch pressure plate? the clutch plate and friction plate are the ones that had just fried an week ago (3rd and 4th image)

Also if you look at the plate it has uneven wear on the back side of the pressure plate. (might be hard to see in the image) I use a torque wrench and evenly torque the springs to 4.5 foot pounds

I fear that the plate has been warped by the temperature created from the excessive slipping!

Should I be replacing everything involving the clutches then?

not on someones initial opinion/suggestion to check over the internet, you need to investigate further before jumping to conclusions



use a flat edge and check the plate for warpage.

did you have the rod adjusted correctly ?
if not readjusted after you installed the new plates it could have been allowing the plates to slip.

did you soak the plates overnight in the oil you planned to use ?

were the dots on pressure plate and inner hub aligned ?

Yeah I adjusted the rod so that the clutch lever (on the case) was aligned with tear drop looking thing on the case. Also went in to make sure it wasn't out of adjustment. it looked fine but double checked everything just to be safe. Ran it down a dirt road and it did it again in 5 mins or less. I soaked them for about 20 mins before putting them in (the new ones have be for about 15 hours) so it could have been the problem but i'm not sure.
And the dots are lined up.

You could also set the pressure plate on something verry flat lije a thick piece of glass or granite if you have it. Set it with tbe bosses/tabs down. If it rocks like grama in her favorite crochet chair its warped.

The biggest question to me is why the nut in the center of the pressure plate so sloppy? I don't remember my buddy's blaster's clutch looking like this.

20 minutes is 23 hours and forty minutes short of the required soak time.

you're missing the washer under the nut, part # 19 in this diagram............

the pressure plate is hex shaped for the inner nut to lock into, the outer nut should not be down inside that hex, kept from doing that by the washer, and completely accessable to hold with a wrench for adjustment lock.
I'm not sure how you even locked it down with it being inside the hex like it is ?
if you look closely to your pic above, you can see the marks from the original washer left on the pressure plate

I have the washer. I had to replace part #6 because I dropped it on the garage floor and it chipped. I have it all up and running now! thanks for the help!
