Got this off Facebook the catcher and drive cover is missing. What I would like to know is can anyone date it and is it an Australian made with a New Zealand sticker or is it an import from N.Z. I am unable to date the motor as the cowel is not original (one of mine). After a Carby clean and point set the motor in running. If any body has a drive cover and catcher I would be interested in purchasing them.

Hello exfarmer

The sticker dates it to when the Challenge Corp. had control of
Morrison. The best I can do is mid-1970s to late 1970s. It is a
fully-imported Morrison.

This is a cheapened design in that a similar system was used in
the Scott Bonnar Diplomat. There is a plastic reduction gear within
the rear roller. A single clutch does the lot.

Note: when I say 'cheapened' - I don't mean cheap. The reduction
design enabled the use of one belt (replacing three chains). The
issue now is parts availability. It appears there may be a problem
with the degradation of the plastic ring gear.

What I have been trying to find out is whether there is any commonality
between the Diplomat reduction, the Morrison, and brands still sold
today with that design concept.

Hope this helps.

Thanks Jack,
You have confirmed my thoughts on the age. I will take the roller out and check the ring gear for size and post photos and sizes for future reference.

Thanks again
Andy

Pulled the roller out to find the plastic ring gear is almost like new. The steel pinion is also in good condition. The roller has 79 teeth and the pinion 12. Roller outside diam is 7 5/8 in, inside to gear points 6 3/8in pinion 1 3/8in. Sorry vernier only have imperial measure (I need new set)

G'day exfarmer

That's really good information.
It appears to be a far better (more solid) design than the Diplomat's
