Hi All,
I have removed the engine from my MTD Yardman mower to check the piston rings as I noticed a large "blow back" pressure ( my own term ) when I remove the oil dipstick when in use last summer. I also checked the compression when cold and remember it reading 55psi and 90 ish when warm. I need to remove the main pulley which is on the crankshaft. I don't want to try a standard wheel pullers as the 2 pulley wheels look as if they could be damaged if I put them under pressure with the pullers. I am considering welding a large nut to the bottom of the pulley and screwing a large bolt up into the pulley shaft which should pull the pulley off the main shaft.
Yardman model 136C561C643
Engine Briggs and Stratton 11.5hp IC engine.
Yardman machines are rare here in Ireland so I cannot ask any questions locally. It has proven to be a good little piece of kit for over the past 20 years and will keep it running as long as I can.
Any hints or advise appreciated.
