Need quick advice

Hi Guys,

I'm new to the forum but need some quick advice. We race a vintage 1974 Z1 sidecar and go racing next week.

I've lost the 600A1200 ball bearing that is in between the clutch rod end and the clutch actuator.
Tried a few ball bearings that I have and the size isn't right .. also they are not available now in Canada.

Can anyone tell me what the diameter is of this steel ball ? The Kawasaki description says Ball Steel 3/8 .. but that can't be the size in inches.

Sizes in metric mm would be appreciated as that's what we use up here.

Then I may be able to find something at a supplier up here.

Thanks in advance.

Mick

Ball bearings are typically made in inch sizes. 3/8" is the size you need.

1 inch = 25,4 mm
1/8 inch = 25,4 / 8 = 3,175 mm
3/8 = 3,175 mm * 3 = 9,525 mm

Can you upload some pictures of the vintage 1974 Z1 sidecar

Scirocco,

The cavity that the bearing drops into looks to be about 6mm max in diameter .. why did you multiply the 3.175 X 3 ?
That would appear to be too big to drop down the sleeve.
Advice appreciated.

Hope fully the sidecar picture will attach properly.

Cheers

When use the bearing that I have big or small. If I tighten the adjuster cover down. When I use the clutch leave I can see this adjustment cover flexing and pushing out .. is this normal ? It's almost as if the adjuster screw is too far out and pressing against the steel cover.

The 3/8 steel ball must be insert form the clutch side into the shaft.



Flexing of the adjustment cover is a sign of a blockage. in the clutch.

When I use the clutch leave I can see this adjustment cover flexing and pushing out .. is this normal ? It's almost as if the adjuster screw is too far out and pressing against the steel cover.

Steel? :huh: Both the sprocket cover and the access cover plate are aluminum.

Should not see any movement of the sprocket cover when squeezing the handlebar clutch lever. Unless the cover screws are loose or stripped, or unless the cover is cracked or otherwise damaged.

Good Fortune!

As I recall, the steel ball inserts into the empty push-rod passageway before the push-rod is inserted into the passageway, all from underneath the sprocket cover (on the port side of the bike where the adjusted mechanism is located). It's unnecessary to remove the clutch cover (on the starboard side of the bike) or to perform any clutch disassembly.

A fairly common mistake after removing the sprocket cover and push-rod is inadvertently allowing the steel ball to roll out of the push-rod passageway without noticing it's escape to parts unknown. :pinch:





Good Fortune!

The ball goes in from the right side.

Guys,

Thanks for all of the great info.

I was told that the left hand side of the engine which has the clutch rod actuator is supposed to have a steel ball but it looks like that was incorrect. I haven't removed the right hand engine cover or clutch basket .. which is obviously where the steel ball is.

I'll remove the additional steel ball that I fitted to the left hand side and see how I do.

Then I should be off to the races literally.

Thanks again.

Mick

Seems to me that Kawasaki's exploded diagram ought to look like this.



Many of the folks that have inadvertently lost the ball bearing had removed the sprocket cover and pulled out the push-rod and didn't notice when the ball-bearing fell out the same hole the push-rod came out of.



Good Fortune!
