I was woundering how you can tell how much pound pressure is on the spring on the secondary clutch? How do you put that pressure on it?


Thanks Bimmer1

do you want torsional(rotational resistance),,,or side pressure(amount required to compress sheave towards open position?

looking for 12 to 14 lbs of resistance, I think it's rotational

use a BERKLEY hand held fish scale, hook it into the balance holes in outer edge of sheave, lock brake on then gently start pulling while observing resistace until the sheave begins to move, this is the rotational resistance(torsional) you seek, this is adjusted by varying the outer tip of secondary spring among the holes, 1 being softest, 4 being stiffest, i assume you know how to reassemble secondary after disassembling to change location of spring???????

Thank you. I have reassemble them before but didn't know how to get the pound resistance.

Not at all trying to be a wiseguy, but I have seen some real colossal misunderstandings in my time...

1. The belt must be off the secondary.

2. Give it a couple rotations by hand to make sure it is free turning, not restrained by corrosion, belt dust buildup, etc.

3. Use a padded vice grip or a small woodworking clamp to squeeze a piece of heavy cord or fishing line next to the movable sheave (you do not want to scratch up the secondary) if you cannot get a hook to hold in one of the balance holes.

4. You want to be pulling at the outside circumference of the secondary clutch. If you put a C-clamp on it and then hook to the top of the C-clamp you are getting a longer lever on the spring and changing the pounds of pull at which the sheave will move.

5. On secondary clutches that COMPRESS the secondary spring when the clutch closes, the reading you get with the same spring will vary depending on the helix installed.

6. The condition of the rollers and buttons and bushings will also affect this measurement.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :bowdown: :bowdown: :bowdown: :smilielol: :smilielol: :smilielol: :smilielol: all he wanted was a way to measure the load, 3 and 4 are useless excersises in futility, you'll scratch it more trying those idea's than ever with a fishscale :werd:

On a secondary clutch with a stamped steel sheave, I am not able to get a hook from a fishing scale into a balancing hole.

But, thanks for the advice and the cute icons.

Don't bother with the scale method on the polaris secondary. Always start with the secondary spring in #2 position, and adjust tighter if slightly higher rpm needed, or the rpm fall then recover when the secondary shifts.

he was originally looking for 12-14 lbs, hence my reply

I use a punch that fits in the balance hole and hook a fish gage to it. Circumfrence is the same so the lever effect doesn't apply. 12-14 lbs is either #2 or likely#3 hole. Buttons and bushings must be good. I know too much info. :Wow1:

"Circumfrence is the same so the lever effect doesn't apply".


I use a punch or allen wrench in one of the balance holes also. Just be sure the fish scale hook is touching the outer surface of the moveable sheave and not on the end of the punch. You WOULD gain leverage if you hooked on the end of the punch.
