JDcrawlers Messageboard

Lavoy provides this site for us to use, and he sells parts. Check with him.

Replacing the pump is best, but if you must get it started prior to getting one, there are a couple ways you can try. First, If you used a WIX type fuel filter, be sure the top seal ring gaskets are in the groove up in the housing head, not down in the relief area with slots in the top of the elemen...

Are you sure the lever hasn't fallen off the transfer pump? I've seen that happen. The new pumps (the non-rebuildable ones without the sediment bowl) are not expensive. I would replace the pump with one with the priming lever, you are right there now, and it may be in a much less convenient location...

No, a 450 housing will not fit a 350.

Have you checked with Lavoy? Have you called any salvage yards? You may want to have your crawler serial number and the casting number that is on your housing in hand. The parts catalog shows a serial number break with two different ones used. I don't remember of hand the difference and am not sure ...

Your JD350 service manual, SM2063, should have some info on starter repairs, it will be helpful on the solenoid and Bendix drive if you decide to open it up.

It may be as simple as some rust on the solenoid plunger and cleaning the plunger and solenoid will fix it. For lube at the most wipe the surfaces with a rag having a bit of oil on it. You don't want much there or it will collect dust and dirt, leading to sticking. That said. I would recommend you t...

Look for a tag on the generator. Delco Remy generators had tags on them (not saying it hasn't been removed or a rebuilt was installed at some point). In general, if the tag has a black background, they are 6 volts. 12-volt tags had a red background. 6 or 12 volts was generally embossed on the tags. ...

In the online parts catalog, it looks like that flywheel was used in crawler serial number 706658 and the machines after that one. It also was used in the 350Ds.

If you add your general location to your profile someone might happen to know of something in your area.

Merry Christmas, happy holidays to all. Best wishes, stay safe

Good evening, Just an FYI. This post will likely get moved to the Late Models Board as it relates to a 350 series. This board (Messageboard Q&A and Announcements) is for questions and comments related to function of the boards and related announcements. I replied to your first post and posted the li...

There should be a spin-on filter in front of the radiator and a cleanable screen in the right side of the transmission behind a three capscrew cover, the transmission must be drained before opening that one up. And you only want to use John Deere Hy-Gard or an equal fluid meeting the JDM J20C spec. ...

Sounds like you need the proper Operator's and Technical/service manuals (and a parts catalog if you don't want to use the on-line one) for your 450. The technical manual will have the info on checking and setting pressures and you should have it for your transmission overhaul. I expect Lavoy can ge...

On your #2 item. I am understanding you are talking about adjusting the HLR clutch valve nut adjustment. What manual do you have? I looked at my 450E manual (TM1330OP) for the procedure. Step # 5 says "With both gear shift and H-L-R Levers in neutral and brakes locked, start engine and run at slow i...

Good morning. Others may disagree, and be along with some other thoughts, but it sounds to me like you have a big issue developing. Binding up and not moving in first gear sounds like possible bearing issues in the transmission which could result in a catastrophic failure. As for the HLR engagement ...
