Re: Now have a 78 JD350C

Regarding the 420C, it is original only one. Bruce

Re: 6 volt change to 12 volt

I agree with all that Stan has stated. Yes, 6 volt systems started as pos ground. May have have been changed to neg ground. To provide concise instructions, I wanted to know the systems current configuration. Best regards, Bruce

Re: 450C Hydraulic pump

Yes, I have replaced the pump. You may be tempted to remove the pump without removing the hardnose. To save yourself, it is easier to remove the hard nose and then work on the pump. Bruce

Re: oil leaking from steering clutch housing

Must be leaking from the clutch pressure manifold, part # T41473. There are a couple of o rings inside this manifold that are likely the problem.

Re: 450 B or C? New Member

Nothing wrong with reprints of the originals. I try to find originals, but that is just my opinion. Three manuals that are important are: technical manual, parts manual and owners manual. Send an email to this forums owner(Lavoy) to get access to this sites dedicated photo server. You can read about...

Re: 450 B or C? New Member

Welcome to the forum, The SN plate for the B and C series has two rivets holding an aluminum tag to the front side of the left box. Most of the 450's I have seen without the tag will have the SN stamped into the steel box directly under the area where the tag should be. If the box has no tag and bee...

Re: jd440ic charging issues & hyd cyl issues

I may have suggested this before, but here we go. I have not owned or worked on your specific levers. I have seen pics before the whole pic disaster happened. In non-critical apps we have used a center punch to "knerl" both mating surfaces. This may tighten your levers. Jim and others have good advi...

Re: I Bought a New Toy

Does the straight 450 have the small fuel transfer pump in the right side of the engine just in front of the starter? This pump has a small oring that fails and can send fuel directly to the engine oil on 450C. These transfer pumps easily replaced or rebuilt(if they are the old style). Bruce

Re: reverser oil flow question

Could the buzzing noise be pressure escaping through a faulty valve? Which one? Pressure builds up from the pump, so the pump is good, right? This normal pressure overpowers a faulty valve, causing valve to open and spill pressure down to zero. Buzzing noise is the vibrating valve. Faulty valve can'...

Re: 1010c Diesel loader

First, welcome to the forum. Lots of good info and people here. A far as I know the 1010 never came with two batteries. If your crawler has two it was added by a frustrated previous owner. The machine would not start easy and they increased the cranking amps with a second battery. Problem is they pr...

Re: reverser oil flow question

I have heard and known of several large Cat power shift rebuilds that the owners tried to do "on the cheap". They didn't replace the cooler. And I every case, that I remember, the power shift failed prematurely. I have been told the cooler MUST ALWAYS BE REPLACED. I'm not sure I have ever heard this...
