OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers Scott Bonnar 45 (14") clutch repairs

Hi everyone, just signed up to this forum.

I bought this mower secondhand in 1977, the only mower I've ever had and just for home use. It got a new B&S motor in 1995.




3 years ago I had a major service done, at the time seemed worth spending money on it after so many years plus some sentimental value(quite expensive):
- sharpen and set of reel and bottom blade
- spark plug, air filter, new oil, chains adjusted
- clutch repairs...clutch cable, inner cone, key, engine shaft, thrust bush, thrust race bearing, 2 bearings, half circle cork.

Motor still starts and runs great but a couple of weeks ago I took it in to get the clutch adjusted as the reel was turning sometimes when disengaged and I seemed to be pushing the mower a bit rather than the mower driving. They adjusted it but said the clutch needs some work done on it at some time (quote was $350).
It now drives OK but when disengaged the reel still spins and the cluth assemble/shaft is making crunchy noises....fine when engaged.

I'm concerned if I don't get the repairs done I may damage the engine shaft etc. but I'm a bit over spending a lot of money on it especially after previous exercise. I'm thinking of taking it apart myself and replace damaged/worn parts, but as you can probably tell I'm not overly mechanically minded but have the time and willing to give it a go.

Is there anything in the clutch assembly not replaced last time that could be expensive or could some of those same parts need replacing again after 3 years? Any advice would be appreciated.

Regards
Garry
