Yes, Just running the Stock spring w/ the Dalton Weights.

 

Try the epi red or white. But thats just a guess.

Your stock spring has rates of 55/110
The EPI red has rates of 54/140
The EPI white has rates of 91/155

I would start with the red. If that isnt enough then return it and go with the white.

 

Thanks Danny, It turns out I already have a new EPI red spring still in the boxI bought and never used, I will give it a try.

 

Red primary or red secondary????

 

That's funny youasked me that, I was Justlooking at it and yes it is for the secondary.At least thats what the EPI installation kit says.

 

If its about 3" long its a primary and if its about 5 to 6" long its a secondary.

 

The spring is3 3/4" of an inch long

 

Thats a primary i believe.

 

BCS24 is the primary.

 

It could be, Its possible I got some things mixed up. A have a lot of spare parts floating around.

 

If you can get it in the primary then its a primary spring.

 

Also i can measure an epi red secondary for you tomorrow and let you know the exact length.

 

That would be great danny, I dont have a part number, just installation instructions.

 

Not a problem. Let me get to my shop and i will measure it tomorrow. But the primary is about half the size of the secondary. But i will measure it tomorrow.

 

danny, you overlooked the simplest check on primary vs. secondary. the secondary is larger in diameter 2 1/4" vs. the primary's 2" diameter. the length of the red EPI secondary is 5 1/2". the green/yellow dalton primary is 3 3/8". i don't have a stock primary to check since i gave it to a buddy with a brute force.

kevin, if it's 3 3/4" long, its the primary spring. that spring will have nearly identical engagement as the stock spring, but like danny said, it has a higher spring rate, so it'll raise your RPM's a bit during shift out. you've got the 650 helix and the red EPI primary to try out, both are easy to install and check. just make sure you get everything lined up and the helix stays put when you put the secondary back together. i sit on the ground, put the helix on (make sure its seated on the teeth it engages), then use the spring to put pressure against it to keep it from coming off those teeth. use both of your feet to push the secondary on the shaft and thread the bolt on by hand. its awkward the first few times, but it gets easier to do the secondary work after a few times.

 

Yeah Brian i forgot about the diameter...DUH im retarded sometimes.

Kevin-Let us know your findings so if anyone else is having the same problems, they can see your results. KS

 

You guys are givin me nightmares......hahahaha.

 

One thing I found on my 1004 outty the other day, was the fiber bushings were worn out in the secondary. This let the sec bind up on takeoff. It would rev high when first kicked, then the revs would fall real bad, letting me believe the pri spring didn't have enuf rate. I had it clutched correctly a while back, and this came up. I took the sec off and found the bushings were worn, enuf to let the helix wear. I replaced the inner part of the sec, which was the one with worn bushings, then it was right back to where it needed to be again, shifting perfectly. We really do need a roller secondary, with a steel helix, to help with some of this problem.

 

Dave-ARe we off on what we posted?

 

No, no...LOL. I've just got clutch weights, springs, multi-angle helix's spinnin' in my head all winter from dealing with my sled....missed all the quad talk.

 

Thanks everybody, Your right wake I have had the secondary apart a few timesnow and it's no fun, I will definately let everyone know of all my findings, What worked and what didn't,

Its tough to tune when you just want to play.

 

Was glad to see talk about clutching for sand ben trying to get mine setup. Lots of good info here. ben ordering parts will start the clutch fun when the snow go's. We run 300' or 500' tracks.Kevin why is your rene only 2 wheel drive? What kind of paddle tires you run?

 

Hey Robert, Nice to see a fellow sand runner. It's all about weight. I don't need the 4X4 on the hill, I have run times in and out of 4X4 and what we found on the up hill drags was a loss of 4 miles an hour. They just seems to fight each other at high speeds not to mention the front doesn't sped a lot of time on the ground any way. As far as paddles I run 10 paddle and 12 paddle depending on sand conditions (wet or Dry). with the 10 paddle I don't get out of the hole as fast but it gives me the drive up the hill, and with the 12 paddle it gets a little scary out of the hole but by mid hill I loss top speed and drive. This where the clutching comes in to play, I am going to see if I can fix this.

 

Has anyone ever weighed the stock Rene weights and the Dalton Pro clutch weights DBO800R kit? I have, 3 stock wts. were 33 grams, 3 were 34. 3 Dalton were 34 with no rivet. wheres the difference? I installed the Dalton kit with steel rivets like the directions called for and lost 3 tenths off my 300' times. Shift out was to soon 6500 rpm . Thats with green spring and stock 25" tires. Shouldn't the weights be lighter? I decidedto sand 2 grams off 3 stock weights and install with Dalton and use orange EPI spring in pri. red in sec. with 650 helix. hope to get 2200 engagement with 7300 shift out. By the way Wally World has digital gram scale in the cooking gadgitaile 30 bucks. Going to test and tuneFri.

 

if you are looking for a higher shift out, you definitely don't want to add rivets to the dalton weights. i'd ditch the red secondary for what you are doing. i think that and the 650 helix will slow down your shift out way too much and you'll lose even more time. a shift out of 6500 is way too low, even for stock everything. did you use the three 33 gram weights or the three 34 gram weights from the stock weights? a 7300 rpm shift out shouldn't be hard to get, but if you need even lighter weights, you could try some stock 650 weights or the dalton 650 weights. the stock 650 weights aren't as aggressive in the profile as the dalton 800 weights. i took some pictures last weekend that i'll post when i get some more time comparing a stock 800 weight to the dalton 800 weight to a stock 650 weight.
