Chain alignment

[Brent]

Hi I have a max 11 and am having a problem with the front chain on RH side of machine. Changed the tensioner, new chain but when I turn tensioner pops up then the chain loosens and bangs. seems the chain from the adjuster to the front sprocket is a bit cock eyed. Is ther a way to adjust chain alignment or am I missing something?

I've never had to align mine but then it has never had a bearing or axle job yet.I don't think misalignment could pop the tensioner and it sounds like tensioner problems.Try measuring the sprocket from a fixed point on the left hand side and see how alignment looks there.I do however think it is possible to get a misalignment when changing axles/bearings unless original position is marked carefully.Just my thoughts,I'll turn it over the the bearing/axle experts.

Also check to make sure the locking collars are still on the bearing(s). Your axle could be sliding in and out of the frame / tub some causing the misalignment.

When you changed your tensioner did you just replace the nylon slider or the whole assembly? Could the "teeth" on the back of the tensioner be worn.

Finally, are you getting both sides of the tensioner all the way down in the notches when you press them down?

Just a few thoughts.

Try measuring the distance from either edge of the drive sprockets to the inside edge of the outer frame rail. Then measure the same way on the tensioner.

Example: if the distance from the inside edge of the front sprocket to the inside of the frame rail is 2 5/16" then the measurement taken the same way at the corresponding sprocket at the center axle should be really close to the same 2 5/16". Then use the shims to allign the adjuster as close as possible to 2 5/16" measured from the same side of the sprocket to the frame rail.

When you drive the machine the chain will "want" to run in a straight line between the axle sprockets. If the tensioner is not lined up, the same force that pulls the chain in a straight line will become a prying force and cause the tensioner to tilt thereby popping it loose. I am going by what I have observed while working on Mudbugs Max IV. Your machine may be different, but on any machine the components must be such that the chains run straight between the sprockets. Hope this helps
