Intake valve clearance is commonly found to be tight. It causes hard starting. When choosing shims try to stay exact or on wider end of spec. They intake valves tend to tighten up over time. Also you might find that temporarily installing tensioner before rotating engine to install 2nd cam bolts will prevent the timing chain from jumping time. Great video!
Ok so go the timing down fine... double checked it gave it a good couple manual rotations. Started the engine. Tock tick tick tick tick. Same damn sound. Pulled the valve cover. Checked clearances. Exhaust 010 010 008 008. Timing chain side Intake 000 000 000 000. Timing chain side They are out of spec on exhaust. Is that the tick tick tick?
question about setting the crank in relation to tdc compression stroke. how do i know where the crank must be so the ecm knows that the 1 cylinder is on compression stroke? im into an engine and am not sure if im on compression or exhaust intake stroke.
Great question. To time everything correctly, you'll want to put the PTO or CLUTCH side piston at it's highest point. Line up the timing mark on the flywheel like we show in the video and verify with a screwdriver. From there, you just need to set the cams up the same way we show in the video, and that will give you TDC on the compression stroke for the PTO side cylinder. The ECM will know what to do from there. -Charles
You can replace the hose with something else. Check out our OEM parts page to find out if we have a hose for your specific model: www.rockymountainatvmc.com/oem-parts
If anyone can tell me what those three Allen key bolts right next to pto shaft are used for it would be appreciated. I can not find anything online. And also does a 2014 rzr 900 have some kind of oil pressure release?
Hello I have a polaris rzr xp 900 2012 do you know if 2012 bottom crank case fit my let me know because I can't find the 2012 bottom crank case thank you
The top and bottom come as a pair. Looks like the case halves aren't shipping right now. You might have to keep an eye out for something used or see if a machine shop can repair yours.
@rmatvmc the case I bought from ebay it's a 2013 xp900 and my it's a 2012 xp900 sorry I didn't tape correct but my it's broken from inside so do you think can fit the 2013 case to my 2012?
Hey i keep going back and forth with this video... I purchased a 2012 rzr 900 xp that sounded like it had chain slap.. I suspect the stock tensioner took an early retirement. I purchased and alba racing tensioner... I put it in and still had the slap.(everything was top dead center). SO... I took the cams completely out and started from scratch watching your video... top dead center is easy.. Getting the cams aligned with the slots and home fashioned tool to keep them straightis fine... i run into this issue.. When I take the rear alignment tool for the slots out.. the intake cams jumps forward causing the chain to slip gears... it also jumps out of the alignment that i just worked so hard to get... what am i doing wrong? I have watched this video of you doing the timing at least 15 times... I just can not see where I am making my mistake..
You can find the Polaris OEM parts finder here: www.rockymountainatvmc.com/oem-parts/Polaris Just enter your machines year and model, then go to the engine, crankcase schematic.
Awsome video thats exactly what i was looking for.
Glad the video was helpful! Thank you for watching.

Exhaust
010 010 008 008. Timing chain side
Intake
000 000 000 000. Timing chain side
They are out of spec on exhaust. Is that the tick tick tick?
Where do I order different size shims
@@timwise1758 most times a dealer will swap you, mine did. Otherwise you can order a complete kit that has many sizes online.

@@rmatvmc perfect. that was my conundrum, i wasnt sure of the ecm would assume it was still on the actual compression stroke
I have a problem with the water hose, it broke and I can't find the original. Could I put one that doesn't have the same mold as the original?

Are all these steps the same for a Ranger 900 xp?

Did you see that I released the tension with a wrench on the intake cam? I'm guessing that might be the issue.

Like to see a video of 800s rebuild engine
Where can I buy blue/yellow bearing ?

It would have been wise to turn the engine after torque of lower half.

I’m confused when did he put in the valves
Welp. Ive decided buying a new motor would be cheaper. From factory piston arms were not torqued down all the way to the crank.
Was the motor from Rev6? Cause i heard they were junk. Plus after talking with one of there techs, they do a shitty job. They reuse all TTY bolts
