Help! Turbo pro eating belts. What to look for?

[MATCO]

Around 1500 miles on my turbo pro I started losing belts rapidly. About 1 every 100 miles of hard backcountry riding. However my buddy has the exact same setup and has 800 miles on his belt in the same conditions.

What should I be checking?

Why would this problem suddenly happen?
So far I have gone through 3 belts in the last week.
Also, I have developed a intermittent bog at WOT. Only happens sometimes at high boost. Not as much when the boost in down but still there. Maybe related maybe not.

Any help is appreciated.

Thanks

Check your motor mounts.

Motor mounts and torque arm are the first things to check for sure. The turbo sled eats em up.

Which belt?

 

[MATCO]

They do seem worn out. What do you recommend replacing them with?

Which belt?

Tried both Polaris and cat belts. The Polaris belts pull cords and the cat belts break cords and strip the cogs off back side of belt.

I'm running stock mounts with a boost-it torque arm. No problems.

 

[MATCO]

I don't have access to boost it products as they will not ship to USA so I guess I will buy all new stock mounts and a SLP torque arm. Hopefully that will hold the beast in place so I can stop buying belts.

Has anyone ever seen this issue cause a intermittent bog at WOT? It seems that the belt issue started the same time as the bog.

 

[Hairy Mark]

i think that you fix the motor mounts you will fix both problems.

Being your going to deal with SLP buy this tool

Unfortunately you need some feeler gauges to use it and I dont know where you'll find those??

 

[joshkoltes]

You say this happened out of nowhere, your sure you didn't clip a rock? Mine was out of alignment due to impact I ended up having to shim the right rear mount .030 forward to bring it back at one time

clutch spring?

belts

My 3" track sled ( 174 ) is also hard on drive belts .
I went with a TKI kit and am using a much lower gear ratio. 2.43 I think..
Used to smell my drive belt getting hot/ready to come apart on long full throttle runs in the very deep snow.
Now i can run the throttle taped and do not smell the belt and it has lasted a complete 5 day trip with great snow conditions.
Liked the lower ratio so much a purchased a second kit for my sons turbo 13 pro. Stock Polaris 163 track. Not as hard on belts but still eats em up.

My thoughts only. Works for me.

Do you "break it in"?

 

[Polarisrocks]

Is the belt blowing up? If you're pulling strings on the inside the clutch needs to come out. if your pulling strings on the outside reshim the clutch in. Your alignment tool if not gonna work with a turbo sled. Shim in out .020 thou at a time till you get it.

I think both your clutches need rebuilding. They are most likely worn out. After that, check your parallelism.

 

[Danny Dangles]

I have recently started pulling cords on the outside of my belts (2500+ boosted miles on my sled.) It was great otherwise up until this point. Motor mounts are all recent, I really need to add a boost it torque arm as well. Which alignment tool do you guys recommend? Will I be looking at shimming my primary or secondary?

 

[kgra]

Only the secondary is adjusted for belt alignment.

 

[Polarisrocks]

There are washers behind the secondary on the jack shaft. Polaris sells several different thicknesses for this adjustment. If you have a turbo on that sled it is pulling harder on the motor mounts and usually the alignment bars are out the window. If you have a lead adjustment you may want to increase it a bit. Lead is how far the motor is adjusted ahead so under full load/shift the motor is torqued back to a zero perfect aligned position. If your torque stops are too tight it wont let it come back to the zero spot. '

I replaced all my mounts and found the stock torque arm was broken. I also added the slp arm and now that motor will not move. Put on 40 miles and the belt still looks brand new.
Before I could grab the primary and move the engine around.
After the engine will not move at all.
Best $99 I spent is the slp torque arm.
