Might have jumped the cam chain I've read if you turn the wrong direction it will jump timing. Man that sucks hope you didn't damage anything inside. Good luck

 

It's at the shop. They should know by tomorrow.

What all could get damaged?

 

Hopefully it's just the timing chain as desertdog mentioned. It has happened to others when turning the clutch after a belt failure.

 

If it is such a big No No there should be a dummie sticker on the clutch cover. There is enough dummies stickers everywhere else on it. Lol

 

Isn't that the truth....that would actually be a helpful one lol!

 

Bingo!

Manual tensioner.

Does it require constant adjustment? Or set once and done?

 

You rolled the primary Clockwise or counterclockwise ? I agree there should be a warning sticker or How about a cam chain tensioner that does not bleed down letting that happen.

There are aftermarket manual tensioners you just have to upgrade....

Rotated clockwise.

 

Nothing other to report other than zero compression. I tried to find out more but I don't think they took the cover off yet.

 

subbed, your only supposed to turn it counter clockwise right? I'm going to pull my cover and draw some arrows on it with permanent marker this weekend. Free mod!

Alba has a new automatic timing chain tensioner (uses a spring not oil pressure), for a little more than their manual tensioner.

Yep, there should be a sticker.

 

Yep! Great idea.

 

sounds like possible bent valves..or jumped time so far that valves are not closing on compression stroke.

 

I'd say jumped a few for sure. It was just running before it was parked.

What would make a crunching/grinding sound if you spun it backwards? Teeth on the cam gears? Or crank gears?

 

If it jumped timing enough and then you tried to start it, bent or broken valves and possibly broken piston.

Also, a mechanical tensioner won't prevent a timing jump from turning the primary the wrong way (clockwise). When you turn the primary counter clockwise (direction of engine rotation), slack would be created on the cam chain on the rear of the engine where the tensioner is. The tensioner takes up that slack while the engine is turning or running. What happens when you turn the engine backward (primary clockwise), is it puts the slack in the chain on the front side of the motor where there is no chain tensioner, thus the timing chain jump usually on the exhaust cam. The only way you could stop this is a tensioner on both sides of the chain.

 

Oh Ya. Ok shes screwed then. Lol

 

So...when replacing a broken belt one should only turn the secondary (transmission) pulley? I'm scared to mess with anything in there after reading stories like this. However to replace a belt one must rotate one or the other to get belt in place.

 

Put belt on primary. Then on the bottom of the secondary. Then roll the secondary counter clockwise.

 

So far I have been lucky but I put a manual one on right after I got my 1000. Also I had them on both of my 900's. Purchased all three of the manual tensioners from Swingarm1 ( Tim ) he has them in stock.

 

But that still does cure this problem.

 

It may not prevent it 100% but I've helped rebuild enough 900 engines and timed them with the stock tensioners and manual tensioners to see the difference. I have changed a lot of belts over the years and yet to have a engine jump time.

 

So you agree with Ken though Nathan?

 

Yes what he is saying is correct the tensioner only pushes on one of the two chain guides. If I had a pic I would show what it looks like under the side cover. My point is the manual tensioner at least applies a constant tension while the engine isn't running and helps reduce the chance of it jumping.

 

I heard it also bleeds down after time. Does the thread sealant totally cure this? I've heard both. Some say never adjust again some say adjust at valve service time.

I guess while you're do the valve service I'd say it's one thing to check for sure.

I have the SAL extended warranty but heard they aren't the best to deal with.

 

I have worked on hundreds of engines with timing chains and as long as the tensioner does not bleed off then you can turn engine in either direction, with the manual tensioner the chain is always tight and the only way the chain could jump is if manual chain tensioner is not adjusted correctly. There should not be any slack on either side with manual chain tensioner if adjusted correctly.. Also they do work great! JMO

 

Correct I have yet to see an engine with a manual tensioner jump time. As I stated earlier when you see the difference between the two while timing an engine you'll understand. As dartersracing said there is no slack for the cams to jump.

 

Ok great. I'm loading up the ammo for the dealer to battle aftermarket warranty.

So technically. This should never have happen. Would everyone agree? If the tensioner was holding pressure and doing its job the chain should have been tight.

Correct?

My argument is if the chain tensioner was keeping the chain tight this would not have happen. I say I go to SAL with this. It's the truth. No need to make up some excuses.

 

On Polaris machines the stock tensioners never hold pressure and that is why it says every where to only turn counter clockwise to prevent damage..I'm sure lots of people turn clockwise and get lucky.
