So ive been Trying to tighten my chain but for some reason it just wont move in either direction....first off is there a built in stop on the housing? or does it just need to be taken apart to clean out what ever debris is keeping it from turning...any advice would rock

 

brand of bike would help

 

Robbed from another site....

First of all you need 2 people to adjust it. (or something that was the same weight as you or the rider)
1- loosten the two large bolts/nuts on the rear of the carrier bearing.
2- sit on the bike and bounce the suspention a few times to settle it.
3- while you are sitting on the bike, put the bike in gear.
4- roll the bike backwards until the top of the chain is tite. This will move all the slack to the bottom.
5- in your tool kit (if you still have it) there is a steel rod. Have your assistant insert the rod in the hole you can see in the carrier, it is located behind the rear sprocket. You may have to adjust the position of the rear sprocket to see it.
6- Now, you should be able to move the carrier. Keep the top of the chain tite and measure the slak (up and down movement) of the chain on the lower side.
7- adjust the tention until you have 3/4 to 1 in of movement.

NOTE - you can use the rear sprocket hub to move the carrier if you want. Just put the bike in neutral. Use the hub to "bump" the carrier. Just remember to gather all the slack to the bottom to measure it.

 

I appreciate the advice but let me clarify. I have tighten the chain a few times before but what I'm having problems with is the tensioner is not moving at all in any direction. What do I do

 

Oh and its a bomb ds650 pipelayer

 

I don't have a repair manual yet, so .... My guess would be that the cammed chain tightener that sits inside the axle tube has dried up/sticky grease where it's meant to rotate, and that's stopping it from moving. Otherwise, you have bigger problems that would stop it from moving. I would try loostening the bolts as much as you can and spray some PB Blaster or WD40 in there. When you're done, make sure you lube the chain tightener up again. WD40 is not a lubricant. BRP indicates to lube that area, but it dosent's say wheither it's oil or grease. I would assume grease. Good Luck.
