Polaris 800 Crank Problems?

Dear Ralph:
Is there a problem with the cranks on the 00-01-02 800 Polaris? I know of five that have broken the P.T.O. side after 3000 – 5000 miles. Also, does Polaris know about this and did they fix it for 03-04? Would I be better off to put a single pipe and reeds on a 700 because my 800 was stock and it blew apart? Do the 700′s and 800′s have the same bottom end? Please help me make an informed decision. The magazine is great! Keep it up. It’s nice to get the straight goods not just brand bashing.

First, I would have to say yes, there has been a number of PTO end failures on big block Polaris twins. Some of the earlier 600s and all of the 700 and 800 share the same basic bottom end, but we see most of the crank issues on the 800s. Presumably due to the higher output and stronger vibrations of the bigger pistons and more powerful engine. We had the PTO end break on our 2004 Switchback 800 and found availability of PTO ends and complete crankshafts to be questionable. Allsport Polaris (509-926-5044) has developed a good fix for this, and now has a good stock of parts (PTO ends and complete cranks) on hand.

Is this a huge problem? No, but there is room for improvement. Every brand does have a percentage of failures in every model they build, Polaris included. I tend to believe if you increase the output of a 700 that you’d pretty much be in the same boat as an 800 in terms of output and stress on the crank. For instance, we’ve had an 800 Polaris twin ever since they came out. Our first year 2000 RMK 800 136” lost the crank the following season in the first few weeks, then we had zero issues until the 2004 went down. The 2001 800 LE ran great, a 2002 RMK 800 continues to run strong, our 2003 RMK 800 is tricked out and running strong, and our 2004 Switchback, well, you already know about that one.

  1. Yes my crank broke on my pro x 2 800 with only 1200 miles on it and i know of 22 other poeple who have had the same problem and polaris wont stand behind them . that is why I sold all three of my sleds and bought ski doo’s for me and my kids. i also sold my outlaw because it has the polaris name on it.I feel with all the problems they should at least call a recall . Just look on the net at all the problems and you will see what I am talking about.

  2. I own an 01 xc sp 600 edge and it was spun/twisted two cranks in a row. The last crank only had about 400 miles on it. It has never broke a crank, they just spin/twist and though the sled out of time. Need less to say I am not very happy about it.
