I just had my skidoo secondary apart to inspect and clean and printed out the pinned BIEGE SECONDARY chart. When I looked at the pretension rates, they didn't appear to follow any order and are just random numbers. On the inside of the clutch hub are three holes A B C .Hole B puts the most tension on the spring, with hole A next and hole C the weakest setting. On the helix are six hole positions. Hole number 1 puts the most pretension on the spring and the tension goes down progressively as you go down to hole number 6. Therefore the highest pretension you could get would be holes B and 1,which should be around 30 to 32 pounds. The lowest pretension you could get would be at holes C and 6, which would be about 2 pounds. The chart should read as follows. Holes B1-30 lbs.,B2-25 lbs., B3- 20lbs., B4-16lbs., B5-11 lbs., B6-6lbs. Holes A1-28lbs., A2-23lbs., A3-18lbs., A4-14lbs. A5-9lbs., A6-4lbs. Holes C1-26lbs., C2-21lbs., C3-16lbs., C4-12lbs., C5-7lbs., C6-2lbs. If someone could print this out properly and make a chart out of it and pin it at the top, it would be great, as I don't know the procedure.

Your calculations are wrong lonewolf. It does work out at random,in addition the poundage is not just what it takes to pull off the spring, its an average taken between the pull off and the release poundage.

I'm sorry,but I have to dissagree with you on this. If you take your clutch apart and look at it and the position of the holes I've mentioned and then look at how the spring is tightened, you'll see exactly what I mean. How in the world can B4 be 30lbs. and B3 a one hole tighter setting be only 6lbs. See what I mean? Also on the weakest hole C , how can hole C4 be 26lbs. and the tighter setting of C2 only 7lbs? I spent a lot of time measuring and that chart just doesn,t seem right.

heres a chart for the beige spring
Lonewolf, I see your logic but remember you have to preload the spring to get it behind the cam ramp before you push the sheave down . As you move the spring around to different holes you might also be preloading back a different distance or degrees of wind to catch the next cam ramp, that changes things.
I've noticed even the chart is not always exact as springs wear or are made different. The last few new biege springs I got from doo have read a little low at the chart settings, I usually just tell people to put them in at B6 and don't worry about it.

Hillppounder is correct, if you don't think he is then get your self a fish scale and work out the different settings. Its when you pre-load the spring and need to prte-load to the next cam that gives you the big variances.

Sorry for that one guys. You are all right and I had it wrong. When I was doing the spring changes I was using an oil filter wrench on the helix and I guess it was so much easier that I was jumping over to the wrong cam angle. Ooops.

I dont understand why youd need an oil filter wrench on the helix, it doesnt turn? I just wrap the clutch 1/3 of a turn and push the helix down and install the snap ring and washer.

I guess I do it different. I hold the clutch solid and then give the helix a turn with the oil filter wrench while turning the spring compressor I made till I can install the little key in place. The wrench is only used till the helix starts on the cam ramps, then I take it off. It works very smoothly especially if your a Lonewolf. :D :D
