Hi there,

 

My name is Vern and im in Alaska. I have a 2019 ranger 1000 xp HL crew. So the machine had zero issues with clutch or shifting. then the belt blew. i got the new Polaris belt installed with no issues. i cleaned everything and made sure all belt debris was removed. installed new belt.  now it lurches in gear and is hard to shift if at all. when i insert clutch spacing tool in secondary and relieve belt pressure then in shifts when off no problem. the secondary is spinning fast when in park or neutral. i did try adding and removing shims from secondary also without any change.  the primary moves in and out without issue. it appears there is no issue with primary or secondary. im stumped. can u help please.

ENGINE OFF.  Look at primary (PRI) pulley.....does the belt fit "tight" and rubs on the slider sheave......this is what makes the secondary (SEC) pulley spin in neutral.  Manually spin the SEC pulley.....does it bind and drag at the PRI pulley? 

Options for the problem:

Some aftermarket belts are cut wrong and the inside groves do NOT match the pulley groves and/or the number of groves are different than the pulley groves.  Count both groves and location.

The PRI pulley is NOT opening wide enough.  Did the belt shred with strings?  Sometimes the strings (cords) get UNDER the sliding sheave and bind....keeping the PRI pulley from opening wide enough.

Mechanical wear on the slinger weights, the pins, slides, bad rub wear spots inside...requires PRI tear down and tools.

Remove belt and hand squeeze the PRI sheave.....no binds and pops back to the idle position with a clunk at the stop.

Start motor (no belt installed)  rev up and watch the PRI sheave movement.  Should close up and then slam back at idle.

Don't know about the ranger. But when I changed the belt on my cfmoto. Once everything was back together I had to spin the secondary sheave backwards 4 or 5 turns. To tighten the belt on the sheaves.

When the belt went out it shredded and bits of cord and rubber was in the primary sheave. Had to clean that out.

Also use a green sos pad to scuff up the sheaves.

 

That's all I got. Best of luck and keep us posted on the progress.

      I have a 2016 Cub Cadet 750 Challenger Crew. My in tank fuel pump is inoperative. Can I put in an external inline electric fuel pump to replace the intank one? The inline ones are about $350. An inline electric one is about $25. Both are easy to replace just really expensive for the intank one. Any kind of inline external pump I should look at? What PSI is needed? Thanks for any help

      I have a 2018 Massimo Buck 400 with 278 miles. 
      Having issues with my brakes. Took the buggy hunting and when I let my foot off the gas pedal it pulls without pressing on the brake. I looked and the pads on all 4 wheels are all toast. The E-Brake hasn’t been on since I have had it. I am guessing it may be a master cylinder issue because all 4 pads are gone. They all seem to have worn evenly that’s why I think the master cylinder. Just got the machine used from a older couple and they said it sat for some time in there pole barn. Possibly the brake lines? Calipers? I took one brake apart and when I depressed the caliper it didn’t stay. Any help is muck appreciated.

      Just bought my first SxS 4 days ago. Looking forward to hitting some trails and back roads. Having a few issues with the machine(Vector 500), but nothing serious. Just setup and tweaking. I would like to by some accessories, but I don’t seem to be able to find much which is machine specific. Or at least my machine. Does hisun offer accessories? Any advice would be appreciated.

      Just bought a used UTV, my first SxS.  It is extremely LOUD!   Was thinking of wearing shooting ear muffs to muffle the noise but then my passenger( wife) and I couldn't hear each other over the shouting we have to do now.... On the other hand we sometime ride with my brother and his wife and would like to be able to communicate. We throught about FRS and/or GMRS radios (we are licensed for GMRS) but we'd have to wear earphones under our ear muffs. My state doesn't require helmets to ride UTVs.
      I suppose if everyone has a cheap FRS/gmrs bubble pack radio with a ear phone we could all talk to one another. Just wear an ear plug in the other ear or ear muffs.
      Looking for suggestions.
