Re: Leaking fuel filter drain.

Try an industry standard #903 O-ring with a Durometer of 90. Material needs to be fuel service rated, like Buna-N.

Re: How to bleed air from a 350c/ or fuel problems

The shut off solenoid is internal of the pump, under the top cover. If you decide to pull the cover off be very careful as things in there must go together correctly and cleanliness cannot be stressed enough. As I posted before try a jumper wire to bypass the switch and wiring between the switch and...

Re: 450C fuel strainer on I.P.?

If it runs, an injector with air should clear itself after a couple minutes of runtime, without bleeding.

Re: 450C fuel strainer on I.P.?

After reading LeonardL's reply, a thought occurred to me. Is this a new issue or has it been ongoing? If it has been this way since you got it there is the chance the injection pump is not right for the application. If this engine came from a stationary application, the pump adjustments and governor...

Re: '73 - 450B Crawler/Loader/Hoe Restoration

Not surprising on Hartville. If you look at their website, they are basically a JD residential dealer lawn equipment and compact tractors, not even an Ag line, much less construction/forestry equipment. Many dealers will sell parts they don't have in stock. I have been told by the guys at a couple J...

Re: How to bleed air from a 350c

If you get fuel coming out of a line at an injector, steadily, stop cranking and tighten it. Crank again, then tighten the next having steady fuel. Also try a jumper wire from a power source (battery positive, battery cable stud of the solenoid, battery stud of the alternator) to the shutoff solenoi...

Re: 450G steering valve

Welcome to the Boards. Thank you for reporting back on what you found; it may help someone in the future. Right now, with a 450G, you are one in the minority here who have machines that new, so your info is building a base for others who will follow.

Re: 350B identification

That front panel is not part of the seat so I would not see needing to replace it. You would be the one who would have to answer that. Didn't you have the serial number recorded prior to the fire? It is not uncommon for the wrong decals to be installed after a paint job. Over the years many machines...

Sorry, but that serial number is not a 350B. Machine serial number tag breakdown using the 350 Introduction from the JD parts Catalog: SN = serial number T = Tractor 4 = JD350 F = Crawler - Dozer 3 = Diesel D = (Transmission) Sliding Gear with Reverser Serial number: 066244 (This number falls in the...

Re: How to bleed air from a 350c

You should be able to bleed the filter and push fuel to the injector pump (loosen the inlet line at the injection pump end after you have bled the filter and closed the bleed plug) with the hand lever, not cranking. The engine must be cranked to bleed the injection lines.

Re: How to bleed air from a 350c

The hand lever on the pump is related to the pump lever that runs on the camshaft. You would not get much, if any, resistance when you stroke the hand lever unless the cam is in the right position. If the cam lobe has the pump lever lifted, you won't feel much on the hand lever. It is not uncommon t...

Re: How to bleed air from a 350c

How much fuel have you put in since it ran out? Bubbles in the filter is not a good sign. A low fuel level in the tank could be a problem. You could have a loose connection somewhere between the tank and pump. The fuel transfer pump may be failing and is drawing air in. Watch the engine oil level. I...

Re: Straight 350 dozer PTO/Winch output cover

I see what you are saying now, I was looking at the outer cast shield not being two separate pieces. Yes, it looks like you have the 4A guard (plate) which should have the shield #1 pressed into the hole in the center of it. 4B (one piece cast shield) is the part that superseded those two parts. One...

Re: Straight 350 dozer PTO/Winch output cover

I think you have the 4B cover, at least I can't see a separation, it looks like the one piece T64423 shield to me. If you have a shaft behind it I would expect it to be a winch shaft. It looks like that is NLA. If you look at the PTO shaft in the parts manual you will see it is a lot longer that tha...
