I believe the cam chain tensioner on the 400ex is automatic, as with most if not all of the newer quads.
chcek out your loacl partshouse and get a timing book
Yes it would all the models are almost the exact same.
the answer is yes. since the tensioner is hydraulic and require oil supplied from the oil pump to add pressure to the sleeve/guide.
0 to 50 on a good day
not gospel but 4.0 sohc engine is an interference major damage if timing chain or timing chain tensioner breaks
on the front of the frame and on the bottom of the motor by the sprocket
0.028
There is a bolt in the center of the tensioner (silver). Turn it counterclockwise to loosen it, and then turn the tab with the hex hole in it to the left as well. You'll need a hex-key for this second step.
take the plug out of the side of the bottom where the stator is,is a lite and find T[top dead center] then find T on your cam and align then with the chain any more questions mattgalloway2009@gmail.com
Are you replacing a whole clutch or just the clutch plates?
there is 2 clamps. one on the front and one on the back
1. For a 2.4 Quad you have a plunger that bolts on which gets it's pressure from the oil pump. The tensioner just needs to be reseated no bolts required it will set next to a piston type plunger and all you need to do is manualy turn the engine 2 to 3 turns and if the plunger is good the little piston should come out and put pressure on the tensioner and tighten the chain. If it does not come out assuming you have plenty of oil in your engine then you need to replace the tensioner which is around $40.00. Tensioner has a round hole in it and slides over a pin on the inside housing and if the plunger is working it will reload the tensioner. After engine restart you may hear the chain as if it is loose but the oil pressure will balance out the needed plunger pressure aganist the timing chain and will quiet down.
