Title: About the cam-chain tensioner
Post by: GSJames on September 14, 2005, 02:13:46 AM
Hey all,

So I got to removing the cam chain tensioner cause of davipu's suggestion.  It seemed to work fine, that is, when I let go of the screwdriver, it would spin and the piston thing would come out.

The thing is, if you cranked the screw right all the way, and then slowly removed the screwdriver, the piston would not move.  Did Suzuki make it this way - so that it was easy to install?  Or is mine screwed up?  (So you'd turn the screw clockwise all the way until the piston got "stuck",  put the thing back on with the allen bolts, and then turn the screw slightly counterclockwise so it went tense again "unstuck the piston", and then put the cover on with the screws)???  :dunno: That's question 1.

Anyway I put it back in, reassembled the bike, and I'm still getting the same knock-knock sound when I rev up in proportion with the engine speed.  :x  I wanna ride the bike, but until I know what's happening for sure, I don't want to risk ruining it at all.

Oh, another important question about the cam chain: whatever the cam chain tensioner pushes against - should that surface have some play?  I decided to shove a screwdriver in there and prod around, but the surface I hit didn't seem to have any play in it all - which made me wonder if the cam chain tensioner even if it was working would do anything at all.  That's question 2.

And also, about spring "rewinding" - it seems the spring is physically attached to the spinning rod on the inside, as well as the outer part.  How do you rewind the spring then?  Wouldn't you have to crack the spring off those things its connected to - meaning ruining the device?

The spring is anchored to the outer wall ... Mine was off the wall ... came loose. The way I did it, I anchored it well with a piece of thick copper wire, then I wound it, letting the plunger come in, then un clasped it and turned it and made the plunger go out but turning it, then wound it more etc ... If I remember ... Your tapping may be cam shaft end play, or a valve loose ... even in spec it still taps ... I set them under 1 thou and still hear them ...
Cool.

:lol:

Well, it sounded like good advice at the time.   :P

No answers to either of my 2 questions though?  Cause it still might be the tensioner and/or the thing inside the engine it pushes against.  :dunno:

Here's a pic, is it suppopsed to do this?  (Note the piston fully down, without me applying any force on the screw at the bottom)

Running without it totally ruins the engine - removal to check function or to replace is the only reason to remove one other than working on the cam chain ore removal/replacement of the head.

Running without a CCT is BAD!! I recently had mine ACCT retensioned and now after being used to a rattle on decel it's eerily quiet again  :thumb:
