  • 4m40 injector pump timing

    How do you adjust it to make sure it is right...

    get it done properly by a dyno tune mob.

    I spoke to Cooma Diesel Service in Fyshwick ACT - they sem to know a fair bit about the 4M40. Unfortunately as they are soo far away I could only use their advice and a local dyno mob to get mine right - but when I next need to Paj injectors done ( about another 50K) - I might even go for a bit of a trip.

    The pump plunger lift is set using a special tool and then the pump body is rotated ( I think) to get the timing right - both important to get max power, min smoke and keep the exhaust temps within reasonable limits.

    have fun, Lambie
