crap, no wonder ive noticed it louder lately then, i messed with it, hmm,, how to tighten a little ?

thanks!

You shouldn't have to tighten it.

You shouldn't have to tighten it.

Its self adjusting. And it's probably fine. If you have engine noise its probably just engine noise like the rest of us have. Unless you have a manual, and can understand how to take the thing appart for insp. and cleaning leave it alone. You'll end up with it broken, or leaking oil.

wellthe large round thumbscrew endof it oppositeof the endof it with the lock screw and nut i turned, i dont remember which way,and italso likepulls towards back, spring loaded,it returns back by itself due to a springonthe shaft of whatever the thingy is,.

does turning it adjust anything or does lock screw or nut have to be loosened first before turning the large end does anything ?



thanks

Please note these are for an 1100, yours is probably similar,looks like you must first remove it and check it out, directions start at bottom of 1st page..

hmm... very interesting, hmmm...

yeah im just gonna leave it all alone til i maybe get a clymers some day somehow- i dont know how or when
im mechanically inclined, but im used to and learned on GM engines, so...... hmm...

\
justhopei didnt adnjust anything by messing with the big thumbnail round wheel thingy on the LH end of the shaft of this adjustor thingy.


anyone know ? thats all i need to know for now, i willkeep the above pics on HDD and get them printed out when i can

what URL are those at ?



thanks

I was afraid you may have loosened the plunger and wedged the tip in there as it released, that's why i posted the whole setup procedure as, IMO, not knowing what you did exactly is kind of scary, I'd fall back and re-group

what URL are those at ?

I think you need to take it appart now.

I think you need to take it appart now.

If its out of adjustmen I think you can re-adjust the stop setting without taking it appart. You'r best bet is probably to get a manual and go through the procedure outlined for inspecting cleaning and re-setting it.

Yea a manual is a necessity if you're going to lay hands upon...

These are for an 1100, similar perhaps

Howdy Everyone,

I just replaced an O ring on the cam chain adjuster which had gotten hard and was leaking oil and messing up the lower half of my (79) GS850GS engine.

That was in the morning. I took it for a long ride to see if I had truly solved the oil leak and, although it is too soon to tell, I heard some loud "cam chain type rattling before I got back home in the afternoon. Sounded serious. I wear earplugs when I ride, and I could hear the "rattle" very clearly. It didn't occur until probably 30 miles after I had replaced the "O" ring.

My manuals aren't very helpful regarding the cam chain adjuster.

Has anyone had this problem?

I backed off on the holding nut and unscrewed the interior screw a bit (and then re-tightened it), and the noise has gone away . . . but that doesn't mean I've done the right thing.

The cam chain adjuster does not ever need adjusting, the books say, but I had to take the screw and holding nut off to replace the O ring which was leaking.

I'm not seeing oil now, so it looks like my O ring replacement was a success, but what is this rattling noise that I encountered?

I may or may not have fixed it with my fiddling of the screw within the locknut on the left side (facing forward) of the cam chain adjuster.

Any advice, questions or comments?

Mucho gracias,

Mike

If I understand what you did correctly, the inner screw you tightened down is not allowing the tensioner plunger to operate, it needs to be loosened 1/4 to 1/2 turns and then the lock nut tightened

but what is this rattling noise that I encountered?

she's not self adjusting, read the top 3 manual pages

 

[Anonymous]

thats why i was wondering why i was toldis self adjusting if theres a manual adjustment shaft and locking nutonit,that would be same as saying that the clutch is selfadjusting!

so to adjust the camchain at adjuster you take and turn the screw shaftall way in and then back out alittle ? or ?
this cant be THAT complicated....
mine has some oil seeping on it, where is it leakingfrom ? its my only oil leak on the entire bike...

what can or should i do ? the last page says to tighten all way down so it DOESNT plunge..
so i am confused...


thanks

Ok its not self adjusting.

Ok its not self adjusting.

I suppose it's not self adjusting. If you reset the lock screw you have taken it out of adjustment. When I said self adjusting I meant that the tension spring keeps tension on the cam chain automaticaly.

Try turning your back wheel while in gear to see if you get any action on the dial. If the screw is backed out far enough it should alow the dial to turn as the slack in the cam chain tightens.

 

[Anonymous]

dial ? eh ? what dial ? where ?

now im even more confused

however, just aftermakingmy above reply i went out and pulled the bike out of the shed and fired her up and loosened the locking nut and turned in the screw tilit stoppedand hten backout a little bit and htne locked the nut,and theres a good difference after doing that: something seems tighter wheni revit up from idle and it shifts easier, still have sometimes problem of finding neutral and hitting 2nd from first on acceleration under load.

thanks

shouldi tighten up the adjusting locknut shaft restof way clockwise- the last about halfa turn in clockwise and then lock the nutback again tight ?

it seems somuch better with what i did in my last reply just above,theres noticeablylessslack soemwherein the drivetrain after doing that, but i dontknow what,

or is the shaft supposed to be backedout a hair after all way in just until it stops- when turned inwards clockwise ?

want to findout before going for it, i did it while engine was running and it didnt make any sounds changesoranything, but it doesnt slack "clunk" near as much from alow idle rev-up like it did before i did that adjustment.


thanks

cam chain adjuster, GS850G

cam chain adjuster, GS850G

Here I am a month later. I finally understood that the set screw needs to be LOOSE by a 1/4 to 1/2 turn. After replacing the O-ring I was advised (by someone who should have known better) that it should be tightened down.

Anyway, the cam chain noise is (I hope and pray and it seems to be true) gone.

What I have now are oil leaks worse than I started with, replacing that O-ring on the adjuster nut/set screw.

Looks like I'm going to have to take the thing off and replace the O-rings and seal which some kind soul (thank you, whoever you are) gave us the part numbers for. I ordered them this morning.

As for taking the adjuster off without taking the carbs off . . . I have lots of tools but I just don't see how it can be done. If somebody reading this has some advice, please give it to me.

Somebody said it was a 20 minute job, start to finish, using a Sears swivel. Well, whoever that was, please tell me where you live and I'll drive my bike there and save some money and/or trouble and pay you what you want.

When it comes to cam-chain adjusters on the 850, unless your engine has just skipped a few teeth on the sprocket, leave it alone and mop up the little puddle once in a while. If you don't, you'll have a pool to deal with . . . and that's if you're lucky. If you're not lucky, you'll screw up the adjuster and skip some teeth on the sprocket.

I'm no expert. This is just what I think I know now.

Mike
