Re: Cat grader start up
Nice old grader 
Do all old Cat engines need a so much cranking to get them to go? on a hot day too!
Probably just me but it sounds like he's got a leaky valve.

Re: Cat grader start up
Hello Adam
I have got three Cat machines, all donkey start.On average in cool weather mine takes about 3 minutes, I start by motoring the diesel with the donkey to build up oil pressure for one minute.Then motor diesel on compresssion ,fuel off to warm up the cylinders.Then diesel throttle on 3/4.The D2 D4 and the 933G take about the same time.With a warm engine they will start in no time at all,10 seconds.I have an electric start on the 933 donkey engine which helps.
But mags can be a bit tempremental,the UK's damp climate don't help

Hi Adam,
For what it's worth, on the farm where I was a pre-college student in the sixty's we had a selection of D2s, a couple of D4s and a 3-cylinder D6(2H).
For all of them we used much the same procedure as outlined by B100 Loader with perhaps a little longer on compression before letting the fuel in - starting was nearly instantaneous, no misfiring or white smoking. Think that the grader motor was a bit sick! The golden rule was to always turn off the donkey fuel and let it run to a stop rather than stop it with a float chamber full of fuel.
We also had an International TD14 that had a carburettor and spark plugs, diesel injection equipment and an additional combustion chamber on each cylinder opened and closed by an extra valve - start on low compression with petrol and then close off the extra combustion chamber and switch to diesel!
