It will by all that have reported on it. Alba and Sparks sell the manual adjuster. I don't have the noise yet but will probably add it to my Sparks clutch order.

BTW, how long does the noise last?

I've never heard it either til yesterday, now it does it on every cold start. It lasts only a second or two on mine, but it can't be good for the motor. I can't believe some of the Micky Mouse engineering on these things.

 

The hydraulic tensioner seems to be a very popular style with many mfg's. Not defending, just stating. Just don't rev the motor when cold and you more than likely will not jump a timing gear.

Mine does the same thing with less than 50 miles on it.

 

Mine has done it from day one with about 175 miles on it now.

 

Mine started doing this after a trip to the dunes! It rattled so bad I really thought my engine was shot!! I bought the Alba manual tensioner plus their oil that they suggest and switched to a Napa filter. My machine runs so smooth and quiet! I just put on over 200 miles in Taylor park and was flawless!! I am good friends with my Polaris dealer and he even commented "boy your engine sounds so smooth and quiet compared to others"!! Its easy to install and I think it is a wise upgrade worth the money!

 

Part number for the napa filter?

 

a manual tensioner with fix it immediately. better oil helps but it will come back when the oil is ready to change.

 

is this item/condition covered under warranty. Mine started making clatter on start up last week. Only 250 miles. Sounds horrible for several seconds. I hate to spend $200 & the time to fix something that I could get done for free.

 

Dealer told me normal not covered by warranty unless it breaks . Same old story. Mine has done it since new now have 1850 miles still rattlin

 

I am in the automotive business & a hydraulic tensioner that can not hold pressure is considered faulty. I guess the bean counters @ Polaris have figured out that it will cost less money for them to replace a few engines than many faulty tensioners.

 

Wix filter ....alba manual tensior...and good oil = quiet like a mouse ! All the time every time !

 

100% agree. its crazy how nice and smooth these motors are when the chain slop and Polaris oil is out.

 

How often do you have to adjust the manual tensioner. I have the Castrol 15W50 oil & the K&N oil filter.

 

I have come across 2 schools of thought on this.....

1) Check when ever you start to hear that familiar tapping sound.

2) Check at the same interval of valve lash adjustment.

In any case, I have read where guys riding street bikes going over 15,000 miles with no adjustment needed and still going.

 

Don't have the answer to that ....put a ton of time on mine so far and only checked it once and it was still spot on.....everyone will probably have different results for that cause wear and stretch will vary engine to engine

 

Are there any aftermarket hydraulic tensioners out yet?

 

My opinion is if you are going to replace an automatic tensioner (of any type, hydraulic or mechanical), why replace with same technology? A manual tensioner will not fail catastrophically like an adjustable can. And even if the adjustment becomes out of spec, it would be a gradual change, giving you time to "hear" the chain slap before failure, it is not going to just collapse.

New and improved.....isn't always the case. In this case old school IS better.

I understand not being familiar with the manual version and automatic seems better, but given the frequency of maintenance needed for this manual device (very little after initial chain stretch of a new motor), there is no reason to use an adjustable unit.

 

From a quick Google search, looks like Weller Racing and Boondockers have them.

 

Does anyone have a rattling stock tensioner they'd be willing to send me if I pay the postage?

 

I need to find out replacement procedure, torque & chain tension specs. If it is as easy as I hear I will probably go with manual. So far in the service manual all I have found is location.

 

Here is a step by step for initial installation by Nate at Alba, see post #2:
http://www.rzrforums.net/alba-racing/146292-manual-cam-chain-tensioner-xp-900-1000-rzr.html

At first may seem a bit involved, but really all components are easy to get to. And the 2 guys that I have found selling the manual tensioners, Alba and Sparks, are very responsive and helpful.

 

Thanks for the info. Looks like sparks is approx $54 less than alba. part in the photos looks pretty much the same. Waiting on wells racing to respond on their product. Was unable to locate the boondocker tensioner but heard it was pushing $200.

It's actually Weller Racing.

HD Automatic Timing Chain Tensioner - XP900 / XP1000

 

Paul463 , why do you want the tensioner if you don't mind me asking?

 

topgun, thank you for the correction. . I was able to locate the web site & send them an email asking for more specific information on quality & specs on their tensioner. All they had listed was part# WEL4XP011 for $149.99 Just wanted to know how they were pitching their product against OE & manual tensioners ie: spring tension or ratcheting

 

If you get a response, please post it. I'm curious also.

Weller Racing Automatic Tensioner - Polaris XP 900 / XP 1000 - Easy to install - No messing with manual tensioners! - Works on XP900 and XP 1000

 

will do

 

The OE tensioner allows the chain guide to reset to far back which leads to chain slip and loss of timing. Our tensioner retains the hydraulic properties but has been rebuilt to a specific measurement internally that will not allow the guide to fall back.

Thank You,
Kyle Anderson

Sincerely,
Weller Racing

 

Seen that at work many times on 2.7 Chrysler motors. 6 foot long timing chain stretches enough to let the tensioner get to the reset point and CRUNCH, 24 bent valves.:rm_thumbdown:

 

So what is the right wix/napa part number? I run a Wix 51356 on mine. Another guy in a different post said the 51356 wouldn't thread all the way on his. He had to use the 51357 wix. Same with the Napa. Some run the 1356, others the 1357. What's the difference?

 

I read in another post on here the 1357 has a check in it to keep the oil from draining back out when engine not running.

 

I put Mobil 1 20w50 in mine and no more rattle...not sure how the thicker oil we be when winter gets here though..

 

On my 4th RZR using Mobil 1 15-50 with Mobil 1 M1-110 or Wix 51356 filter. Never had any problems.[emoji106]
