I have a friend who has a 98 Sportsman 500 that is popping in the transmission when put in reverse under a load. In forward, there is no popping at all. Any ideas on what to look for? Thanks in advance!

 

its the silent chain in the trans.

 

Yeah,

We tore into it this weekend and found about an inch of mud in there! We will have to replace the input shaft, reverse gear silent chain, and the reverse sprocket. While we are in there we are gonna replace all the ball bearings and needle bearings along with all the seals and the nylon chain tensioner shoe. DO NOT BUY BEARINGS AND SEALS FROM POLARIS. You can get better bearings cheaper locally at any bearing shop.

Thanks for the reply

 

yes my 02 scrambler was doing the xact same thing. i just tanked out the tranny tonite, and slpit ther cases. i discovered that it was the silent (reverse) chain. it was so loose that it was nearly falling off the sprockets. time fer a new one!
