1100 manual chain tensioner installation

mt_archery_guy · Nov 3, 2013

I just installed a manual chain tensioner on a 2014 1100 and thought I would share some info and photos. I put the sled on its side to do this. I detached the oil tank from the chain case and moved it aside. While I had this all apart, I installed a fill plug and a drain plug. I drilled a access hole in the bottom of the plastic to get the the drain plug.

whos tensioner did you use?

mt_archery_guy · Nov 4, 2013

It's an Arctic Cat tensioner for a 600 sno pro.

What a great idea. I have constantly complained about the lack of a drain and fill plug on this chain case. Turns out with a little thinking the solution was very simple all along. Good work!!!!!!

What did you do to combat the rubbing of the bolt head on the oil return line.
Our's rub here and only time before it rubs a wear point into the aluminum return line

Build a shorter bolt!

I built a shorter adjusting bolt and zip tied some heater hose on the line to protect it.

is this a recall or just something some people are doing?

Preventative

Just some security for when I'm 6 bowls back!

It appears that you have a non Arctic Cat adjuster- the cat style accepts a rounded bolt face- and makes it a bit tricky to cut shorter leaving you with a flat face to come in contact with the spring loaded adjuster.

I also notices the proctective over on the spline- just for the install? as I also put on the new chain from Cat
Thanks

That is an OSP tensioner. I haven't seen a chaincase fail with any manual tensioner and a HD chain yet.

Spline cover

It's a back up in the event the two springs cannot hold the shift fork/collar in place.

Are you using the stock spring on that osp manual adjuster. What is the best tension to run.

Sage Crusher · Nov 9, 2013

The tensioner in the first post is the stock Cat style- it has a different spring in it as it has to wrap around the arm to hold outward even tension. Everything in the stock auto adjuster in tossed.
As a rule of thumb- finger tight gives the best results.

I've had a few PM's on where to drill the hole for the adjusting bolt. I drilled it .560" in from the edge of the case. Attached is a photo...best I could get in tight quarters.

No not finger tight on these snopro tensioners you go till there is no
lash between the block and the chaincase . Finger tight will cause too tight of a chain

Use the adjuster bolt

I installed the threaded block into the inner half of the case. Then took a bolt with the same thread and ground it to a point. Then I threaded the bolt in from the inside and snugged it so that it left a divot or pilot if you will. Then proceded to drill the hole from the inside out with a 90* air drill.

Is finger tight also to tight if you are using the Evo mounts & TCL delete?

trdehmer · Nov 22, 2013

I ran my OSP manual adjuster finger tight. That gives about 1/8" of chain deflection/movement.

mt_archery_guy · Nov 23, 2013

When I put in arctic cat manual adjuster, the return spring holds a fair amount of pressure against the chain. I ended up going about another full turn in tighter with my fingers. I'm not quite sure if that is where it needs to be. Here is a photo with it set that way.

Thanks-in the past- you didn't want the chain slapping the case and a reverse rotation of the track took all the slack out and finger from there.
So now when the cover is back on and a few hundered miles when we adjust- measurment will have to be finger tight...it's all we got
