Hello, i have a 99 polaris 325 magnum 2x4, and the timing chain broke and i put a new one on it, but for the life of me i cannot get it back in time? Any help would be greatly appreciated thanks!

 

I guess you mean at least a 2000 model 325..The lower cam sprocket has a mark that lines up with the mark on the bottom of the engine case. This is tdc on the piston. Install the chain and position the cam lobes downward with the index pin slightly inward. You can move the upper sprocket and chain around(without moving the crank shaft) to where both lines on the upper sprocket are horizontal with the top of the head and the sprocket slips on the index pin. If you get off a tooth or two,just pull the sprocket back off and wiggle the chain around a tad. After the cam is secure,install the tensioner.

 

On the crank it has a single slash mark, and a double slash mark, and i only see one cam sprocket? It also has only one single slash mark? Sorry in not much of an atv mech...lol

 

It says its a 99, watercooled linhai engine?

 

Sohc i guess?

 

If it's a CHINESE atv you need to get help in that section of the forum..The 325 Polaris engine is made by Fuji and oil cooled..

 

Hmm thats weird, its a polaris 325 magnum, could it possibly have a different engine on it?

 

The 325 Polaris is certainly not water cooled!It's oil cooled. The upper cam sprocket has TWO lines that align up parallel with the head..

 

Oh ok, i just bought it and it seems that it used to be 4x4 also but now 2x4, someone must have put a chinese engine on it, it has a radiator and everything.

 

You sure it's not a black finned oil cooler that looks like this? http://compare.ebay.com/like/300439918314?var=lv&ltyp=AllFixedPriceItemTypes&var=sbar
