cam chain gear

[mikey]

If your replacing the rubber guide wheels etc is it necessary to
replace the top idler wheel and cam chain tensioner as well or should you just replace the whole lot anyway

[Rich]

Really depends what condition they're in, but with the exchange rate being so good I've just replaced the whole lot for Liska ones in my lump.

Ok cheers rich think the idler gear not to bad
just its slowly turning into a money pit.

Mikey welcome to the world of the zed engine rebuild,most zed motors are nearing or over thirty and moving parts wear/deteriorate,so what can start as a quick strip check and rebuild can turn in to ??????.What i do is if the parts worn or suspect it gets replaced,its just not worth it not to,once its back together thats it for another ten years

[mikey]

Yeah i know mate last one i done was my GS1000 and i replaced
everything in that and that lasted years and years after and ive had me
Zed best part of 18 months only had 2 very short smokey rides on it
and summers coming oh well dig deeper in the pockets i guess.

I know just how you feel Mikey, I've also got a money pit. Made the mistake of refurbing the head and camchain gear, thought bores etc OK. Couple of smokey runs prove otherwise, so the money spanners been brought out for yet another strip down and rebuild.

Not just the motor though john is it i just got a new pair of forks (stanchions) from z power then its all the powder coating that leads to new wheel, head stock, and swingarm bearings then reconditioning the calipers and so on and so on lucky for me im a metal polisher by trade and work for a plating firm so got that side of things done for nothing.

Mickey, Regarding that cam chain gear. What I have found is many of the cam chain sprockets are OK, except that the top idler sproket and the two idler sprockets break down in the rubberised bearing bush. You can check them when they are off the engine by holding the bearing outer bush and check that it and the teeth of the sproket, are one unit.

Some speed-shop specialists disassemble the units and remove the rubber, replacing it with a metal bush.

The cam guide often gets two groove in it, if they are not too deep forget it.
The cam roller (lower middle posn.) often gets chain ripple on the circumference. If they are not too severe leave it.
Inspect chain adjustor end if smooth leave, Check spring has tension.

RegardZ.
