Ive been off the post for a while. The restoration has come to a standstill as the catcher is the last part. Thanks for the drawings, ill be able to use the old catcher for the catcher hooks. Thanks again, Chris

I messaged Brisbane Cylinders Mower Specialist about this make/model and they said the supaswift/bush ranger parts will fit straight on, not the Scott bonnar/rover 45 parts

(a) 3/4 inch engine output shaft with a compression sleeve and locking nut on the outside of the clutch assembly.

(b) 5/8 inch engine output shaft with a compression sleeve and locking nut on the outside of the clutch assembly.

(c) A tapered engine shaft secured with a spring washer and nut inside the clutch assembly (Villiers 2 stroke engine).

It appears to me that Scott Bonnar 33 had three (3) different engine configurations using the metal-to-metal clutch unit?

Malcolm.

Scott Bonnar like most manufacturers only do what's necessary ,the number 36,698 they'd have records that would tell them
the date of production from that number but when Scott Bonnar got taken over by Rover I would assume by now the records are long
gone.

Yes it's a pity they didn't stamp the year on the mower, if you had the original motor you can get the date from that.

Inspect for Damage: Check the roller for any signs of wear, cracks, or other damage. If the roller is damaged, it may need to be replaced.

Lubricate Bearings: Most front rollers have bearings that require regular lubrication. Apply a suitable lubricant to the bearings to ensure smooth operation. Check the manufacturer’s recommendations for the type of lubricant to use.

Adjust the Roller: Ensure that the roller is properly aligned and adjusted. The roller should be level and evenly spaced relative to the reel blades. Misalignment can affect the cutting performance.

Check Roller Condition: Ensure the roller turns freely without excessive resistance. If it’s not turning smoothly, there may be a need for further maintenance or replacement of parts.

Reassemble and Test: After servicing, reassemble any parts you may have removed, and test the mower to ensure everything is working correctly.

Sound like the black goo is grease.

Cheers
Max.

Looks like your Centenary is in quite good condition.

Carburettor is a single lever type (that’s the name in the book of Villiers engines) and will be either 1” or 1 1/8” which were the lightweight and middleweight respectively. Parts for the mower bodies are scarce. Most engine parts are able to be sourced from the UK but frame parts are mainly a case of finding a donor or fabrication. Engine is a mk xic and looks to be from 4/47 based on the flywheel markings.

Manuals are uncommon for these machines. There is a book called The Villiers Engine by B.E Browning that is a pretty good source though.

With starting, the taper needle is set for rich, throttle opened up a little - usually about 1/4 way on the throttle lever which will make the slide sit so that it is open a fraction. Use the tickler liberally and then give it a spin over. Be careful with the crank handle as they can bite if the engine backfires.

Hope this helps.

Kind regards,
Sir Chook

Looking for others who have this BonMow machine, to make contact.

I have a long term plan to have a Scott Bonner Gathering in Redcliffe Queensland.

An open gathering of machines and owners to share and care about this piece of Australian History.

A thought for the future.

Malcolm.

I need to look at it more closely but at this stage I will strip it down and bring it back as close to new as practical.

A couple of things I do need help with are;
1. What color were the cutting cylinders? Black?
2. It is missing the engine cover, so if anyone knows of one that is available please let me know.
