73 Z1 chain oiler pump mounting bolt size ?

Dont know if Im in the right section or not here. I need to know the size of the screws or bolts that hold the chain oiler pump on. Also what drives it, when I look in there its just a hole but the pump has a female U shaped deal on the end that looks like it should go into a male drive lug. Sorry about the terminology, just want to know how its driven

Kawasaki.com shows it held on by a strap

Damn pic wont load
Got it?

Thats the bottle that holds the 90 wt thats held on with a strap. The pump bolts in the egg shaped hole by the sprocket by 2 screws & a hose runs up to the bottle. I need to know the size & the 2 lengths. I can find any parts fiche that shows it

Kawasaki.com 73 Z1 parts fiche wont load for me, says can not be found

Installation notes:
1. Before the pump will go fully into place, the pin in the output shaft must be aligned with the grove in the oil pump shaft by turning the rear wheel around.

Good Fortune!

Something must be missing then theres just a hole there with nothing inside to drive the pump. Doesnt matter if it works anyway just so its there. I cant find anything that shows the pump in any parts diagrams. Got to be an old timer that knows, I should, I bought one brand new & tossed the pump & bottle. :S

There are two mounting screws.

If missing, could:

Find a test screw with threads that fit, and longer than needed to lightly seat.

With info from the test screw, install pump using replacement screws of length that won't bottom out when tightening the pump into place.

kawasaki.com shows the tank, but I didn't see the pump.

Maybe babbits --- I'll check.

Good Fortune!

Tanks and/or pumps on ebay bring big money. :pinch:

Searched again on kawasaki.com and found the pump and screw sizes.

But not yet found the engine part that drives the pump.

Good Fortune!

The counter-shaft sprocket fits onto the output shaft.

Best I can tell, there's supposed to be a "pin" inside the hollow end of the output shaft that engages the "u" at end of the oil pump shaft.

If interpreting correctly, the oil pumps through the "u" shaft into the output shaft, and out holes to both sides of the sprocket which flings it around underneath the sprocket guard over the chain.

When looking through the hole where the pump shaft goes, does it appear that the "u" end of the pump shaft aligns to enter the end of the output shaft where the missing "pin" is supposed to be.

Not a clear pic in the manual. But the output shaft does appear hollow.

Gonna need someone with a better memory. :lol:

Well thats a big help, I really appreciate it. That site wouldnt load for me. In the deep recesses of my 66 year old brain I keep thinking it was a special sprocket that is no longer available but I could be wrong. I just want it to look right I really dont need the rear wheel lubed which is all they ever did. Chain oiler & all if you rode it hard you got 2000 miles out of a new chaim and adjusted it nearly every time you rode it. 12.19 @108.95 was Hayabusa time in 73 going thru in 4th with an RC pipe on it & a no riding fatboy riding.
