Re: Looking to buy a 350B

The measurements you are looking for should be in the JD 350B Technical/Service Manual or an undercarriage reference book. The best I have found on line so far is this chart (from Crawler Heaven which is gone now) giving measurements for some chains, nothing on rollers, idlers, etc. that I have seen...

Re: 450 E

The PRODUCT IDENTIFICATION NUMBER PLATE (serial number tag) is located on the front plate of the battery box. When you mount the dozer from the left side it is right there on the panel, you will likely be looking right at it as you approach on the ground. Here is the info on the three tags on the ma...

Re: Alternator or Generator

Sounds like someone lost the rubber plug normally installed over the two terminals inside the alternator and filled the hole with silicone. From your description of it having an alternator on it now; I believe it was being run 12 volt, negative ground. Some other clues can be: size of the battery ca...

Re: 450C drive lagging then nothing

These things never seem to happen in a good location. In my mind it is not likely to be related to the steering clutches as both sides are affected at the same time from reading your description. Steering clutches are more likely to go one at a time and your C will have wet clutches which normally d...

Re: 450c stump pan assembly

Since you said the counterweights were in the bucket; it sounds to me like you actually have a crawler loader, not a dozer, is that right? The bottom guard parts, Bruce pointed you to, are the same on the dozer and loader. You will likely need this other catalog to find the counterweights and any lo...

Re: 420 left steering sticks

If you pull those 6 capscrews you will be removing the Quill (item 21), doing that will let the differential drop out of place. Here is a link to the page in the parts catalog. https://partscatalog.deere.com/jdrc/sidebyside/equipment/67961/referrer/navigation/pgId/27975 The cam must be rusted in kee...

Re: clutch plate thickness

Likely too late but, I found .330" for a thickness on one aftermarket disc, best I've found so far.

Re: 420 left steering sticks

What do you have for a manual? Name, publication number? if you don't have the right manual you may not have the info you need. My manual (SM2019) says "To remove the cam, uncouple the clutch throw out rod ball joint (figure 145-10-8) and disconnect the four springs. Cam and balls can now be pulled ...

Re: clutch plate thickness

I checked the manuals I have and didn't find a thickness. I would suggest sending Lavoy an email (postmaster@jdcrawlers.com) to see if he can help you. If your disc is out of spec he will have a new one that is correct for your machine. He will also be able to supply you with the JD7 gauge to set th...

Re: Dumped my hydraulic fluid, am I damaging my pump?

They stopped using the lever disconnects during the 350B production range I believe. As far as I know there never was such available for a 450C, so you have to get to the shaft to disable it. https://partscatalog.deere.com/jdrc/sidebyside/equipment/67823/referrer/search/pgId/223838 Can you see the d...

Re: JD 350b weights

Have you weighed your machine to know where you are starting from? Bumper pull or gooseneck trailer? Bucket weight I'd guess at being in the 1500 pound range. Counterweights would be hard to tell. You said they are suitcase weights (these would be like the ones used on the front of wheel tractors by...

Re: JD Parts Guy In VT

I think it's been 2 or 3 weeks since I have seen one of his adds on Maine craigslist, which isn't unusual. Some of the adds said best time to call is at night. You might try that if you haven't.

Re: JD 450C 3325 Winch issue

Good to hear you found the drive problem and it was a simple fix. With the maintenance of the hydraulic sump you should be in good shape for a while.
