SEEMS EVERY TIME I GET INTO THE DEEP STUFF THE REVERSE DOES NOT WANT TO WORK RIGHT, IT WILL SUCK THE BELT RIGHT INTO THE SECONDARY ,IVE TRIED TO CHANGE THE BELT DEFLECTION AND IT DOES NOT HELP,I GOT TO LIFT THE SLED UP AND PUT IT IN FORWARD TO GET THE BELT UNSTUCK. IF I'M ON PAVEMENT OR HARD PACK SNOW IT WILL BACK UP FINE, YOU WOULD THINK WHEN YOU GOT IN DEEP STUFF IT WOULD SPIN THE TRACK ,JUST LIKE GOING FORWARD WHEN YOU GET STUCK. ANYONE KNOW HOW TO FIX THIS?
ANYONE HAVE TROUBLE WITH THE REV.

Im having the Same problem. Wondering if my helix is is a ER helix. Anyone know what this is caused by. I run a strait 48 if that matters

Yes to use engine reverse u have to have an ER helix. They have a notch for the rollers to lock into when u go into reverse so the clutch wont open.
I'm running a ER helix

what helix and spring r u running? any delrin washers?
running derlin washer on both sides of spring. a 720 helix and a black/red spring

well now im stumped! the only thing i can think of is that the rollers arent locking into that cutout and still letting it crawl up the ramps. it cant be ur spring binding cuz u have the delrin washers. only other thing is becuz ur in the powder there is no resistance on the drive train to help the rollers lock into the cutout. dont really know what u can do about that. i live in wisconsin and hardly ever run into that problem. sorry man. maybe someone else can help u out.
the only thing I was thinking about doing is cutting it a little deeper as you said it maybe its jumping out. so cutting it a little deeper may keep it in there?
I just had it out to change the helix and clean it up, the rollers looked good.

what r u running for rpms? u may want to try a stiffer secondary spring to keep it from shifting out so fast. only problem with that is it will bring ur rpms up.
my RPM"S are good right around 7800 its got to be popping out for some reason. and I dont know why.

Ok, everyone is stumped. Lets discuss how the team secondary works with ER.
Nobody has ever described it in detail to me, but this is my perception:
When the engine is in ER, and throttle is applied, making the primary engage the belt and begin spinning the belt backwards..... The secondary clutch's movable sheave will rotate which engages the 2 rollers in the ER cuts of the helix, locking them in so long as drive force is applied in reverse direction, or until forward force is applied.
So if all this is correct, (and please, someone say so if I am off) then it's reasonable to assume something is keeping your secondary from engaging into the ER cuts properly, or at least some of the time. (rather than "popping out")
The first 2 things that come to my mind are: weak spring pressure from either a sacked out spring, or broken spring, and the second being rotational friction.
When you reverse on hard pack or pavement there is much more traction, and load on your drive train which must be overcoming the issue. In the loose snow, your clutch is compressing before the rollers can lock into the ER cuts.

Im not sure if river is doing the same but mine will suck the belt down into the secondary like if you put the clutch tool in and opened the sheves way open then jammed the belt down in there. Did it so bad this last ride, it wouldnt even take off forward afterwards. Weird stuff. I know my spring is good. Has 150 mile on it. Installed this year. Maybe we need to look at the starting pressure on the secondary spring.
I think your on the right track Dan,... I have been sitting here scratching my head trying to figure out how in the heck it could be popping out of that cut as that cut is pretty good size. It would make sense however that if it is never locking in to begin with that the force could be rotating it open... a very strange circumstance, but that would explain it. So then if that is the case, what would be preventing the clutch from counter-rotating and locking into that cut?
One question I have is; Is your secondary holding the belt an 1/8 inch above the top of the sheave as it is supposed to when you come to a stop? (completely closing)

Good question Seth, if the secondary is not fully closing the rollers could be having trouble engaging into the ER cuts.
And Seth....is that the 94 Ford your user name originated from?? lol
hahaha, no, not at all
that's the name the haters on BCR have been giving me in appreciation of all my work here on SW... 94tempoboy.....
lol.... rock that tempo!
BWAAAhahahahahahahahahahaha
See sig line for significance of the "94 Ford"
back to topic now.... lol... still an interesting problem we have here...
