chain adjustment

[andybike]

when adjusting the chain,can you turn the adjusters clockwise and anti clockwise or doesnt it matter which way you turn them?

thanks in advance

If I'm right in thinking your talking about the concentric cam drive chain adjusters, if the bike is set up stock, anticlockwaise is tightening the chain and clockwise slackens it.
:-g

lets say the concentric adjusters are at 9 o'clock position,instead of tightening the chain by going towards the 6 o'clock position can i tighten the chain by going back through the 9 o'clock position and tighten the chain by going towards the 12 o'clock.....if that makes sense?

:knkknk: Let me get back to you on this, I'm going to try it on mine and see

[andybike]

my thinking is that the chain looked a bit too close so if you adjust the adjusters through 9-12 o'clock in stead of the 9-6 o'clock position you would get more clearance between the chain and top of swingarm.

just 1 of my silly idea's lol

Hi Andy, let's see if we can clear this up.

Is your bike up on a centerstand? No centerstand? Get the back end up using a jack of some sort.

With the back wheel up, loosen the pinch bolts at the end of the swingarm. Stick that big 12mm allen wrench in the allen wrench hole in the round adjuster. Move the allen wrench so the round adjuster moves the axle to the rear. You'll see the chain getting tighter.

If you're on the left side of the bike the round adjuster will move counterclockwise; right side, clockwise.

With the back wheel up you'll need to leave some slack in the chain. When you get it where you want it (check your alignment marks on both sides of the swingarm), tighten the pinch bolts. Remove the jack, put a full size person on the seat. Have that person, with their full weight on the seat, hold the bike up. You crouch down on the left side and feel for an inch or so of up and down free movement on the lower run of the chain.

If you have too much or not enough free movement on that lower run, jack it back up and make the correction.

Good luck and don't worry, this will become second nature after you do it a few times.

i'll explain why i'm asking this.

reason is that by adjusting the chain thru 9-6 o'clock position there is now a groove cut into the top of my swingarm(the chain is within the 35-40mm slack that triumph recommend)its not a deep groove but i am eager to prevent it from getting any worse.

by adjusting from the 9-12 o'clock i hope it would still tighten the chain up and give me more clearance to prevent the chain from touching the swingarm again.

i have a paddock stand on the way

j98sprint is correct in pointing out which side of the bike you are working from. There is also another factor. Since the adjustment is made through the concentric cam chain adjuster, the axle is not in the center of the rotating mechanism. If the axle is in the bottom half of the travel (ie 3 to 9), you would turn in one direction. If it's in the top half (9 to 3), you turn in the opposite direction.

If the axle is in the 6 o'clock you can lower the rear of the bike by about an inch and a half by rotating it to the 12 o'clock position and vice versa. I have a Sprint Sports, so my axle starts at the 6 o'clock position, it increases the ground clearance, steepens the steering angle, and quickens the stearing (sort of like dropping the tripple clamps on the fork tubes, but without loss od ground clearance).

I suspect the Trophies, Tridents, and Sprints started in the bottom half of the adjustment, while the original Daytonas, Speed Triples, and Sprint Sports started in the top half of their adjustment due to their more sport oriented market.

i'll give it a try when i get the paddock stand.just wanted to know if it was possible and i cant see why it isnt.

cheers guys

Andybike;
There should be a rubber piece on the top of your swingarm, which is designated "rubbing-strip, swingarm" in frame 7-2 of the microfiche. It is part number 2056920-T0301. It is correct for the top run of the chain to be in contact with this piece at the point where it passes over the pivot- point of the swingarm. This piece will need to be replaced from time to time. Make sure that it's there (It gets covered with coagulated chain-lube, road dirt, and crud, so it might look like part of the swingarm).
If the chain is contacting the swingarm anywhere else, it might be due to misalignment of the rear wheel. There are little datum marks at the bottom of the adjuster and at six-o'clock on the swingarm for this. Any adjustment to one side of the axle must be symmetrically opposite of the other side. (If you go clockwise in the right side, you must go anticlockwise on the left.) Better to view these marks as "from the front", or "from the rear", than "clockwise", or "anti".
Good Luck.
