900/1000 engine complaint
To whom it concerns,
I have a 2015 Polaris RZR S 900 EPS and after about 400 miles it has developed a major engine rattle on start up after setting for a few days. I talked to the local dealer mechanic and was told the cam chain tensioner bleeds off leaving chain loose until it gets oil pressure to tighten after start up. He said all 900/1000 have to same problem and all do it. I returned again yesterday to see if they had any ideas how to correct the problem and was told to use the Polaris extreme oil 5 50 weight and it will help some but won’t correct the problem. I asked about an oil filter with an anti drain flap and was told using any filter but a Polaris would void the warranty. I told him the Polaris warranty is a joke anyway being past my 6 months and would try the extreme oil and a filter with anti drain flap. He asked me to report back if it works.
I then told him I did an internet search of the problem and everyone is having the same problem with the 900 and 1000 engines. Some have even jumped timing and blown up the engine upon start up. He said yes that is true he had 1 jump timing and ruin the engine on start up. After market companies have come up with a tensioner that has a manual adjustment that fixes the problem, but I don’t think I should have to pay to repair a defective engine part that Polaris knows about and will do nothing.
My question, will there be a recall on the bad chain tensioner or will Polaris stand behind any machine that has a failure due to the problem? Please advise.
Sincerely’
Vern Scott Phillips
