See your thread about this on Yesterday's Tractor for my thoughts.

Re: 450 C charging/starting issues
Yes, you can run a wire from the alternator to the starter solenoid. Without it going through a working ammeter you will not have any "on-board" indication of whether or not it is charging. Can you scan or take a good quality picture(s) of the wiring diagram(s) in your TM1102 manual? If you can and ...

Re: 450 C charging/starting issues
I say use the wiring diagram and do it right. If you have the manual with the wiring diagrams it is not hard to sit down with the diagrams, figure out and remove the wiring the Motorola charging system had and insert the one wire needed for a Delco type one wire alternator, which basically is just t...

Re: 450 C charging/starting issues
I had this all typed on the Early Models Board as you just as you made your latest post there. You can use the edit feature and delete the text and replace it with something like Moved to Late Models Board. The battery voltage is low and would be since the alternator is not charging. A properly work...

Re: 420 sprockets
The casting numbers on the sprockets might be used to identify them. I don't know what the casting numbers were or if they used the casting number as a part number. This would be assuming your 420 was never upgraded with 350 chains and related components. You can call Lavoy and see if he has a useab...

Re: 1979 jd 450c track loader hard to start
I would start by talking with the shop that it came from and see what they have to say. A vendor should get the first call when there is a problem with their product. That is the best way to keep any warrantee there might be. When you timed it before pulling the old pump did the timing marks in the ...

Re: 1979 jd 450c track loader hard to start
Out of time?
How did you remove and replace the injection pump? Did you time it before pulling the pump?
what is the replacement pump? Used, rebuilt?

Re: Jd450 straight oil in bell housing. How to find it
Did you ever get the SM2064 service manual? It would be a help to you at this point as it will be better organized than the parts breakdowns. To find the parts you will need to look at a minimum of the front cover drawing, the drawing that has the front input shaft and countershafts, and the clutch ...

Re: 555G Rebuild Questions
Before the engine is taken down, I would say you should do at least the pressure tests for the driveline and hydraulics to get an idea of condition to see what may need attention. Ideally the flow tests should be done as well. The Operation and Test manual (TM1403) will have the procedures and speci...

Re: John deere 350 4 cylinder
There are many things I haven't seen or heard of however I'm with Leonard on this. I haven't heard of a 4 cylinder 350 or seen one. Two things come to mind. First is it might be a 1010 with 350 decals. The second is someone assembled it themselves. Study it carefully, look for serial number tags on ...
