I usually use a small hammer and screwdriver/punch to move the adjuster on my '99. You don't need to move it very far. I wouldn't use that if it is hard to move, you'll chew up the adjuster, but it it turns easy no big deal. Mine just takes a tap, and very rarely needs any adjustment at all.

FWIW I've used the spanner before, but I feel I can be less likely to move it too far if I use the hammer/punch method. YM(ovement)MV.

 

A brass drift and a hammer is ok if your lazy. Use that dedicated tool out of that cheesy tool pouch. Works better, you can tap it if you dont wana put your hammer down. Its not a torque hammer right? :lol:

 

Nope, no torque hammer. eaceful: I've used the spanner and I usually use something to tap the spanner because moving it by hand isn't precise enough. It won't move with a little pressure, increase the pressure and then it gives and moves too much. So I move it back and start over, usually with the same results. So since I'm using something to rap the spanner with, I've just foregone using the spanner. KISS

 

The bolt that loosens the adjuster ring is 17mm.

You need to spin the rear wheel and find the tightest spot along the chain and adjust tension at that point !!!!!

Maybe your chain is worn out and needs replacement ? Know how to determine that a chain is too worn ??

 

Careful using a hammer and chisel / flathead screwdriver. I don't recommend it.

Many guys have buggered their rear wheel adjuster this way, there's a few posts on here about it.

You can probably find the OEM tool on eBay for a reasonable price.

 

Yeah, if you're having that much trouble getting it to move, then you definitely need the spanner.

 

First, are we talking pinch bolt? or the turn the ring tool ? which both can be called a spanner, like said above from Squirrel, 17mm for the pinch bolt, on the ring tool, some shock wrenches work, some not, I'm against using a drift punch etc. and it doesn't take much movement on the rear hub ring to move the eccentric to get tension.

 

Thank you!! i actually do not know how to determine when i need a new chain, i lube this chain approx. 2-3 times a week and this is the first time ive needed to tighten it since i bought the bike back in november. Based on assumptions i just thought i would need to tighten it.

thank you for the tip about finding the tightest spot on the chain, ive heard multiple forums saying that i need to tighten it in one spot move the tire about 180 degrees and check it again. adjust if needed.

*sideways since '95*

 

But thank you guys a buddy of mine had a shock separator??? i think anyways, its a spanner wrench but connected to another one so more like plyers. anyways, it works and fits so i will be using these (with a pipe attached to the end of course, More torque. amiright???)

 

It shouldn't require hardly any torque at all. I can turn mine with only 2 fingers on the stubby handle of the tool once the pinch bolt is undone.

Christ! You shouldn't need a whole lot of pressure to adjust that chain. Mine has always moved quite easy with the supplied spanner.

DwV. I would aquire a proper spanner for the adjustment. You chain should not need regular adjusting. Once, maybe twice in the life time of the chain and sprockets.

If you search you tube for checking wear and how to adjust, you should easily find videos that are good at showing you how to adjust the chain and the proper tension. There is a guy out of GB who is quite good at doing these videos. You will be able to find something that will also show you how to determine if your chain has stretched to an unsafe length. OH MY GAWD!. I went and said stretched chain. Chains don't stretch. The sprockets and pin on the links wear.

Good luck in finding a spanner.

 

The adjuster doesn't take much but the pinch bolt for the rear carrier is 54 ft/lbs.

 

I know a motorcycle shop owner who uses the same method. He swears it works on all makes and models when a spanner wrench is needed.
Have seen him adjusting chains like that too.

 

Someone with lots of experience doing it this way may have the right feel for this way of adjusting, but for a novice such as myself, and many other here, I would worry about causing damage. I would caution though that all you should be doing is light taps of the hammer. For that matter, the palm of you hand should work. If that hurts, there is something wrong. Maybe the pinch bolt is not loose enough, or something is seized up. Look see.

 

Apparently he has plenty of experience, but I witnessed the damage he caused on some bikes. I'm really sorry for ducati owners, those parts are expensive.

 

Did he also use a crescent wrench to loosen the pinch bolts too? I probably went 30 years without owning one of them fooken tools. They ruin more nuts and bolts......

 

If the adjuster ring won't move easily, shoot some PB Blaster/WD-40 in there. It's also OK to slightly expand the area by levering with a screwdriver in the gap just below the pinch bolt.
