OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers front roller ends SB 45

Hi gents, the 2 x black plastic roller ends on my Scotty are very sloppy on the rod which they spin on, approx 3-5 mm each end in fact. Is this normal or do they need replacing as a result of wear over the years?

Cheers - Ross

Hi Ross, If you undo the nut on the right hand end of the rod, and slide the rod out, you may find its the rod that's worn, not the end caps....

Thanks Deejay, I would have though being platic on metal that the rollers would ware first? Anyway will check it out.

Cheers- Ross

Hi Ross, I will be interested to hear what you find, mate.
However, the plastic end caps should not be hard to come by, if they are, in fact, the culprits.

My front roller has many dints in it, is rusted and unsightly for my newly restored SB45. Can anyone see a problem with me replacing the tube with a slightly larger outer diameter tube - 73.03mm OD rather than original 70.00mm OD? The new tube will have the same internal diameter 66.93mm to still fit the original end caps. This simply means that the wall thickness of the new tube will be bigger - 3.05mm rather than 1.5mm.

The only issue i can see will be that i will loose 1.5mm in height adjustment and the front roller will be heavier.

Will the slightly heavier front roller affect the cut of the grass or machine performance? I think not..

P.S it will be 304 grade stainless steel seamless tube - priced at $55.

Plus less prone to more unsightly dints with the extra wall thickness...

Craig.

Craig, did you see the before & after pics of my front roller I posted a couple of weeks ago? I touched it up with an orbital sander & I think it looks much better than what I had. Could even get the result a little better if I had more time. Masybe an option for you?? Depends to the extent you want to go I guess. Re the size I suggest some of the other guys are much more knowlegable than I & may be able to assist here.
cheers Ross

Hi Craig, In my opinion, there will be no probs at all with this solution, mate, as the end caps will still fit, and the extra weight will actually possibly be an advantage. The Model 17 "Supercut" has a solid steel front roller, and is really heavy, and does its job well.
If you were really concerned about the outside diameter, you could take it to an engineering workshop and have 1.5mm spun off it. With stainless steel, you can polish it to a mirror finish if you wish.
