Shim spider or run Thundershift ABC clutch bolt?? Help

prairieguy · Jan 8, 2012

So here is my problem I love running Dalton adjustable weights bc I ride around home lots below 3000ft and make quite a few trips to the mountains and like to pull as much primary weight as I can when I’m there to make my sled rev 7350 but when running Daltons and the stock yellow/white spring the engagement is way too high for me! I have been using the gold spring to help the engagement but feel the gold spring does not pull as hard midrange as the yell/white arctic cat spring.
So me and the brother are both looking into shimming the spider over to get the correct .20 gap and bring the engagement back to stock with the Daltons but I have been researching and some guys are saying just run thundershifts ABC clutch bolt, but no one has really said how good they really do work!!! I’m looking for help on what to do? Buy the clutch bolt and adjust the primary that way or pull the clutch off and get the local dealer to shim the spider for me which they have never done before for someone!!! Since I do not have the tools to do it myself and live in northern sask and am very limited to performance shops!

ABC kit work awesome. Can adjust as the belt wears and no chance of breaking the spider when removing it. Just remember if you want to take the clutch cover off remove the ABC kit first. It does a number on the cover bushing.

x2^ Go for the ABC kit.

X3 ABC kit is working awesome on my 7. I did not realize how far off my clearance was until I got the kit. Super smooth engagement now. Works great, worth the money and super simple to install and adjust.

For you guys that have been running the ABC kit for a while, are you adjusting it for belt clearance and adjust the deflection as your belts get thinner and getting more life (with proper engagement) out of the same belt?

ABC kit

Easy to adjust belt clearance with ABC kit. I have had no issues. Just make sure you tighten the lock collar securly.

Just know there is more to it than just belt to sheve. untucking the weights I find helps alot.IMO

your talking about the distance between the roller and weights Thunder101?

Thunder101 · Jan 17, 2012

Yes. more roller to weight and your belt grip goes up in low range. This is also why Cats have light tip weights bc they lack in low range and have lots at shift out. If you have a friend with the tools shim it, or if your going to oun a cat for years to come buy the tools. I made my oun spider grunt tool. Look on HCS Dono was selling the revised shim and had some good write ups about the angle of the weight to the roller. 50thou it what I remember.:face-icon-small-ton and 10-20thou max for belt to sheave. The prairies blow this time year dont they :face-icon-small-fro Im in Stoon -37 today

I had one on my M7. With all the Mods I did to that sled the ABC was the only product that delivered 100% on the advertisement.

ND. If you maintain 0.20 clearance your deflection will not change that much. That said. Yes and Yes to your questions.

I have a 09 HCR , Have had the ABC adjuster for three years. I was always takeing spider on and off, to shim. never seem to get same width belts. Abc is so much easier then yanging clutch off, and pulling spider off, and hopefully picking the right shimm.I have had no issues and perfect belt clearance all the time.

Hey guys, anyone try the 911 billet cover? Looks like for $240 you get the ABC bolt and a billet cover with a much improved oilite bushing... Looks like that would be the ticket.

if ya had someone to balance it..Racinstation..??
im to far north..

Anyone had any issues with the ABC bolt? I took a look at my buddies before his sled was stolen, and I thought the collar making contact with the cover would eventually make a mess of things.

Anyone?

Oh yeah, I've had that damn thing tighten down on the clutch a couple of times. It is a pain in the ***. I delt with readjusting it twice and said, "no more."

The concept is fantastic, and when it works properly it is good however; out in the west with the heavy, wet snow pushing on the side panel in a L side carve it just can't take it IMO.

Edit: Before I get attacked.... I know how to clean, loctite and properly tighten an allen head set screw.

loctite on collar worked for me

Clearence

You can run less clearance and have great success 15 to 10 thou. Works good

I've been using 911 covers since just after Duane came out with them on different motors/sleds, 9-post and 6-post. Bought the first one used at Rum River Grass Drags and they deliver 110% on promise. The easiest way I know of to make a clutch last longer that the sled ever will. I change my shim stack one time using a cut-down Bearcat spacer but now any other adjustmets are made with the cover combination. And Lonn having the idea to balance the clutch with Thundershift fasteners and washers is brilliant.
