450 D hard start

Zachary Harris · Feb 10, 2009

Hello out there,
I have a 1957 Farmall 450 Diesel. Trying to start the tractor on gas is a pain in the you know what! While cranking on the gas side it puffs out a lot on smoke and takes along time to fire up. when the throttle is shut all the way off, i tried pulling on the throttle linkage to the pump and it is all the way back. If anyone has any ideas please contact me. Thank you

I suggest you get a operators manual and a ISS 1035 B (IH) repair manual for that tractor and engine.
Sorry if thats not the answer you want, without seeing tractor there's a lot of guesses.

The intake switchover butterfly valves must close all the way.
The ignition shutoff switch on the shaft must be ON. The choke must be on, There is no throttle, there is only a diesel speed control for the governor on the injection pump.
Read in the archives about the hundreds of posts on the topic. and as D Slater indicates a manual is necessary.

After doing what previous posters suggest you might try opening the bleed screws on the injection nozzles to see if that reduces the smoke during starting. Fuel will come out as the pump is set to the point where it will not produce enough pressure to open the injector but will deliver on an open line. If this does help you start, then eiether the stop screw inside pump needs to be set or the rack. Just make sure lever on pump will reach internal stop when in shut off positon. I also play with the ignition timing when it is running , setting it as retarded as you can for max rpm. Some 450's do not have any automatic advance mechanism in distributor, early ones had an 8 degree advance and they started a little better.
