Re: 440’s at work
My grandson, 10 and granddaughter,4 were visiting for a few days so I was training the next generation of operators. After going over the controls I sat behind the grandson and we moved back and forth a few times turning right and left. Then we started pushing a little dirt. http://jdcrawlers.lcent....

Re: 440ICD jigsaw Project
Hi, I saw a lot of busted 435 tractors back in the 70s. Ripped out ring gears. Seems as the 2-53 overpowered the 430 driveline when using the drawbar. Where it shined was when using the 1000 RPM PTO on that baler. And, I think that was the idea in the first place. However farmers would see that pow...

Re: 440ICD jigsaw Project
hi JimmyDiesel, I am curious as to what are those 2, big-holed mounts on the rear alongside the winch? It appears that there was once a canopy on the dozer. The remains of the center mounts and holes for the front bars are there also. I have a canopy on a parts machine that will find its way to thi...

Re: 450c won't turn off
Is it possible the new alt. Is actually a 1 wire.
If it is the alt. would keep working after the ignition switch is turned off.
Check the part #, they look the same the only difference being the internal regulator.

Re: 440ICD jigsaw Project
For most people the 2 stroke 53 series Detroit Diesel is a love it or hate it experience. I am in the love it group both operating/driving them and rebuilding them. If I was operating a dozer 12 hours a day it would be a much newer JD or Cat. I keep watching for a 435 or 440 wheel tractor for sale c...

Re: 440ICD jigsaw Project
21 hours on the rebuild. Good oil pressure (for a detroit) steering clutches and brakes working ok. Still chasing hydraulic hose and cylinder leaks. The #64 6 way blade is MUCH handier than the #602 4 way. The engine has a 180 degree thermostat hasn’t been over 185. In the fall the dozer will get mo...

Re: 440icd N, S, pistons and injectors
Pop Pop The picture below shows exterior differences between a 35 and N45 injector. The tag number The tube nut on the 35 has 1 groove. On the N45 the tube nut has 2 grooves. My experience is all N series injectors have 2 grooves. The nozzle tip on the 35 is pointed the nozzle tip on the N45 is roun...

Did you remove the 2 bolts on the backside that go thru the steering clutch housing?

Re: 440icd N, S, pistons and injectors
Pop Pop I am not an expert but have worked with 53 Series Detroit Diesel engines since the late 70’s. The 2-53 that Detroit built for John Deere is a 2 valve 17 to 1 engine with 35 injectors. 2-53 engine production ended in 1972. The best way to know what injectors your engine has is to remove the v...

Re: 440’s at work
The 440ICD 602. ( Ole Smoky ) hadn’t got to play for the last couple months so we put him to work again.
