I refitted the Lister to the saw bench today. Bolted it down, refitted the fan, flywheel and pulley. Then fabricated a longer exhaust pipe to  take the smoke well away. Next I made a shield between the engine and the bench to stop the saw dust being sucked into the fan, I simply used a sheet of old correx (thin plastic sheet) as a wall between the bench and engine.  I lubricated the main bearings on the saw bench – a good dose of EP80 gear box oil should keep it sweet for another 6 months or so. A quick tidy up of the saw blade and we were off – engine started first time – I had already purged/bled the diesel through to the injector.

Probably needs a silencer somewhere in the exhaust pipe but it now seems to run quite sweet and have plenty of power, its also a lot less smokey – no doubt due to good clean air flow and the lack of soot clogging everything up. I also think the compression is a bit higher – less gaskets used when reassembling the cylinder.

It had about an hours run and with the freshly sharpened blade happily went through the big lumps of wood I had ready – including a short length of telegraph pole.

Engine back in position with flywheel fitted.

Correx shield fitted between saw bench and engine – should stop it getting choked up quite so quickly next time.

Cover and exhaust pipe fitted.

 

All done, up and running – made short work of the pile of logs.

 

Top of exhaust pipe – you can see a mild smog around it – still needs a flap to stop the rain going down it. I left it with an upturned baked bean tin on this evening!
