OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers rover 45 drive clutch cork help

hi all,my rover 45 smoked up the other day and stopped rolling by itself, I took off the chain case and found the land roll clutch cork burnt and in pieces.

Ok so the first picture is the cog i took off




the second picture has whats left of the cork is circled in blue

Now what I really need help with it is when I buy the new cork, do I glue it, what type glue do I use and where do I glue it, do I glue it to where I pointed the arrow at in the second picture ?

It is usual to glue the cork to the disk shown in your picture. Gluing helps keep the cork from moving out of position radially. Contact cement is normally used.

Hi PeterM279, and a warm welcome to the forum.
it's great to have another Rover Model 45 owner on board.

My first question here would be...what caused this? Was the drive roller clutch out of adjustment?

However, to put things right, here's what I would suggest:
(1) Order a new drive clutch cork...Click HERE

(2) Remove all chains and sprockets, including the inner half of the drive clutch, and thoroughly clean the chain case area.

(3) Thoroughly clean the inner half removing all traces of old cork and glue by carefully scraping and a suitable solvent....(Methyl Ethyl Keytone (MEK) is great if you can get it).

(4) Obtain the glue....here's a pic...This is of the cutter clutch, but the procedure is the same for the drive clutch.


(5) Replace the cork, carefully following the glue instructions perhaps using a piece of board and some clamps to hold it in place until completely set.

(6) Clean all chains and sprockets, inspect for serviceability, lubricate and reassemble.

(7) Adjust the drive clutch

Happy Mowing.

Hi Again
I now see the photos for the drive clutch.
New glasses would really help me.
How do I remove the sprocket and get access to the drive clutch?
Does to need a pulley or does it nearly pull off when I take out the centre bolt, which is also used to adjust the clutch engagement?
Thanks
Ron

Hi again

Have removed the drive clutch.

Does it matter which side you glue the cork clutch?

Thanks

Ron

Hi Ron, and a warm welcome to the forum. It's great to have another Rover 45 owner on board, as we all like to learn new things and tinker here.

I guess you are talking about the cork itself, it does not matter which side is glued, the most important thing is to remove all traces of the old adhesive to achieve a clean surface before the new glue is applied.

Once again Ron, to OutdoorKing.

Hi after fitting new cork and replacing sprocket how tight/loose should the centre bolt be on the drive clutch?

Hi Paul
The centre bolt on the landroll clutch should just enable the sprocket to
spin easily using finger touch (a bit like adjusting drum brakes).

Usually, you tighten the nyloch nut until the plates grab, then back off
a half a turn or so.

You then adjust the feel of the hand trigger via the secondary adjustment
of the clutch cable.

Hope this helps.
Jack

has helped! thanks Jack
