HELP NEEDED. When setting up the Rupp secondary clutch, are there different coloured springs to use (mine are all rusted) or are they all the same and you just use the numbered holes for different motors? Thanks.

The secondary springs,have different numbers of coils,some heavy wound,some light wound! The different engines,tell you what hole to put it in.The chart below,tells you what hole to run the secondary in,with which engine.

But still I ask, How do you differentiate between the secondary springs AND how do you determine which one to use. I know there are different springs for the primary, but nowhere have I seen anything about different springs for the secondary. I'm beginning to think that all secondary springs are the same, that the only way to adjust them is to use the different numbered holes as per the chart.

Yes it was. As I said ALL the secondary springs I have are ALL the same. The only springs with any differences are the ones for the Primary clutch (different colours) as shown on the chart. There's nothing on the chart about secondary springs. Only hole number.

Alan I use the holes to set spring tension I set my magnum at 16 lbs. 14 to 16 lbs. should be fine. Lower h.p. sleds like my silver bullet [24 hp] I set at 8 to 10 lbs. Hope that helps.

Actually,.........there are 2 different Rupp secondary springs. A large diameter and a small diameter spring. Generally speaking, the small diameter spring works in the 1 & 2 holes,...the large diameter spring in the 3,4, 5 holes. The secondary will bind and will not open completely if you have the wrong spring for the secondary hole application you are using.

Thank you nitrofa340!! I actually had a conversation about the secondary springs,about a year ago,with another member on this board. I told him I was having trouble with shift out on some of my sleds[was going by the info I posted above];he said check your springs.I did,& what he told me was 100% true.Yes,THERE is a difference in the springs.

Thanks guys. I did go ahead and install one of the springs I had, in the number 3 hole. When I checked the tension it took only about 10 pounds to move the sheave. When I recalibrated in the number 4 hole, it took about 14.5 pounds to move it. I figured that's close enough. So that's where it's staying. Secondary clutch DONE !

Here are 2 different secondary springs,one has 4 coils,the other 5.The 4 coil spring is approx 3/16" in diameter. The 5 coil is about 11/64" in diameter. Rupprat,when you got the 14 lbs,was that on a 440,340,295 or what? Nitro? Magnum? Common sled. Just curious.A friend of mine,who has a shop,told me 10-12 lbs. I've heard different numbers,but don't know what is correct.Do you race your sleds or trail ride.I'm sure there is a different tension for the application.

My 76 Nitro secondary, the spring looked to be rust colored. Oh, that is rust. I did see a small amount of blue on it though. Don't know if it is correct, but just thought I would throw it out there.

Alan, I have nothing to add on the springs, just glad to see you recovering enough to work on your sleds. Take care of yourself, from Brandon and Jeff.
