rustydog Posted August 10, 2008 Share Posted August 10, 2008 Just getting started, well trying to get it started, recently purchased B61, w/ air start. Seems to be very small hole in bottom of starter air tank. Is that normal, was some type of fitting there at one time? (perfectly round, 1/16 dia., looks to be threaded). What is procedure to start this baby up, can you bypass the air start? Has not been running in years. Have flushed fuel system. Any advice appreciated.

Freightrain Posted August 10, 2008 Share Posted August 10, 2008 Small hole? 1/16" hole is pretty small. Most drains cocks would have been 1/8" pipe or larger(which is near a 3/8" hole size). So it's an open hole now? It needs a plug put in it for the system to be able to work. Start up? You'll need to air that tank up to 100+ psi, push in the "shut off" on the dash and then hit the starter. Unfortunately with air start you can't "crank and crank and crank" like with an electric starter. You'll get a few seconds of good cranking then it will run out of air and quit turning. Not good for starting an old engine that hasn't run in a while. Lot of guys will pull start them, as you can keep it turning by just pulling it around in circles. Air up the brakes(so you can release the parking brakes--if it has spring brakes on it), then also it will give you brakes for when it does start and you need to stop it from rolling into something.

HK Trucking Posted August 10, 2008 Share Posted August 10, 2008 Before trying to start it either with the air starter or by pulling it, check to make sure the injector pump rack is not stuck.If the rack is stuck closed the engine will not get any fuel and will not start.If the rack is stuck open, you'll get one hell of a surprise when it starts!!!!!!!!!!!!!!
