OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers Scott Bonner 45 issue

Hello Swiftdevil

No, that looks good for a carby overhaul and tune-up.
I note, at a glance, that you are missing the catcher rubbers:-

Hope this helps.

Sorry to be asking more questions but I have tried to look for a manual on the rest of the mower but at the moment unable to locate one. Id like to find out part numbers and exploded views like the one for the engine. Anyones help would be must appreciated.

Regards
Scott

G'day Swiftdevil,

At least a couple of Owner Manual versions are available for download in the ODK Scott Bonnar Manuals section HERE.

Note that this is a paid subscription area - instructions on how to subscribe are at the top of the page.

I think that the first doco on the list there could be the SB45 Illustrated Parts List, but I don't have the access to check that for you - CyberJack may be able to help with that.

Hi Guy's,

Just to clear matters up, there has never been a Model 45 Service Manual, only an Owners Manual which had an exploded parts diagram in it. It's always been a bone of contention as to why no Service Manual on such a complex domestic machine was never produced and that's I guess why we get so many questions here at the ODK regarding this and all the other Scott Bonnar models made over the years.

Cheers,
BB

This is what the Briggs CE8069 Repair Manual lists for tune-ups:


The Briggs 1981 print Repair Manual also says to clean any grass and debris out of the cooling fins. Compressed air is by far the most effective way of doing this.

I do highly recommend checking the tappet clearances, as well. If those need servicing, you will need to order a new cylinder head gasket.

Checking and adjusting the ignition contact points involves removing the starter clutch and flywheel, but that's not usually too difficult.

G'day folks,
I was pretty sure that no Service Manual ever existed for the SB45's, as you confirm. The Rover-era 45 Owners Manual [found as a free Web download] covers the basic adjustment and lubrication aspects of servicing, but doesn't include any parts list or exploded diagrams. Which I'd say is what Swiftdevil is after.

There is a PDF file in the SB Manuals section of the ODK site here titled 'Scott Bonnar.pdf Description: Scott Bonnar Spare Parts List for 14" 17" & 20"' which I think may be the IPL for the 45's, but as I've said, I can't open it to check if this is the case.

Edit: Here's a downloadable IPL for the Rover 45, which should be of some help: https://www.outdoorking-forum.com.au/pages/rover/roller_mowers/Rover%2045%20Cylinder%20Mower.pdf

Thank you all for all your advice and help over this forum. I have fitting all parts that I order from this site and cleaned all parts of the mower. I put new fuel in and tried to start it. After a couple of tries I managed to start it. . Now every time I started it now fires first time every time I'm so happy. I think there is a vibration from the blade bearings I might have to change them. Now I want to clean it all and repaint the whole thing. This will be my next project with this mower. I need to get the rubber mounts that are missing pointed out by Cyberjack thanks. Not sure what else I should look at or repair. I remembered one thing and that's the catcher which is in tact but has a couple of rust holes and is very thin in others. There is also rust on the body of the mower need also to get rid of this.

Regards Scott.
