Post a picture of your primary clutch. I want to see the cover plate
Ya 100%. So probably should go with yellow spring to Increase belt tension. Or from what I’ve read going with the 45 degree helix would also increase the belt tension. Which is better for hauling…does it make a difference?There's 3 choices of helixes. Also, the white spring is a lighter spring @ 58 lbs. This is for over 4000' altitude. It's no wonder it's in a tighter hole. It's too light! As far as the rollers, they seem loose to me but for the life of me I can't remember what mine were like when I had mine apart last November.
Thanks MN! I’ve got a yellow spring in order as well as some rollers. I figured while I have it apart might as well replace. I also ordered a puller and have been putting penetrating oil on the drive shaft. I notice the sheaves are kinda glazed, probably from belt slipping. Will scotchbrite pad help get this off? Or would steel wool be the better option?53 helix is pretty common on these and I don't think that's your issue. I would use a yellow secondary in the middle hole and start with that. I didn't watch this videos but the rollers are usually loose so I wouldn't concern yourself with that.. definitely wouldn't cause slipping anyway.
I've never made a tool to remove primary covers, it's definitely not something that is necessary. And if you don't have a puller you can remove the cover and take out the weights with the clutch still on the machine. I'd definitely want to check your weights and probably put new bushings in them regardless. The pin/bolt for the weight can sometimes wear also and will swing the weight to the side. The rollers in the spider are a wear part also. It's good to inspect them and if they're ok blow them out with compressed air. You can clean the clutch face by running the engine with no belt and use a scotchbrite pad on the spinning sheeves. I'd say most of your problem is probably from the weak secondary spring but I'd still inspect the primary clutch, it is a wear item but an inspection and maintenance can go a long ways if you do it before irreparable damage happens.
I'd just buy a puller, if you're going to have snowmobiles for a while it is money well spent. Cat green puller will work for all these 9 towers and also the new 6 towers up til the metric change in 2010, so mid 90"s sleds to 2009. My puller gets used alot.
The dishwasher!!! Awesome!! If my wife catches me with my clutch in the dishwasher…😬Although some guys use steel wool, the scotchbrite pads are recommended more often. If you use steel wool, use 0000. I have washed mine in the dishwasher afterwards. Yes, the dishwasher. Don't tell my wife though.
