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

Morning, first post for me!

I've had one of the pictured star mowers for nearly a year and its been quite good. The shop I bought it from are retarded however and the last service and blade sharpen took 3 trips and in the end its still not as it should be.

Don't know if i should create a new thread, but the problem i have is that it makes a terrible racket when you accelerate. When i took it into them the first time we started it so he could hear it and he said it was just that the clutch wasn't tight enough, and i think he might have made reference to the allen key bolts on the clutch assembly but cant be sure. It basically makes a very loud rattle or knock under acceleration like something is quite loose, and didn't want to take it back again and was hoping to try and fix myself.

The allen key bolts aren't loose and I'm not really sure what they are for but was hoping for some guidance or idea's on what it might be.

Thanks :-)
Mark

Mark,

If the allen screws have come loose then the bet is the clutch housing could be damaged by making the hole slightly oval. You should be able to see when the engine is running if it is wobbling when engaged.

Hence you will need to replace the clutch housing (worst case).

thanks bruce, the bolts arent loose at all i checked hoping it might have been that. its under a year old so wouldnt expect anything to be worn yet. not sure what else to do to troubleshoot it

billdsl,

Note that the clutch housing is alloy and will wear quite quickly. Can you post a pic of the clutch area so I look at it?

Sorry took me ages to get around to taking some pics of the clutch

dont know if this is what you were after, i tried getting pictures of the position of the allen key bolts

Since this post is over 12 months old, I will now close it.
