JDcrawlers Messageboard

Welcome to the forum, Condolences on the passing of your wife's father. It looks like you have posted the serial number of the loader attachment itself. It is a model 831 loader, serial number 3354, this is just the loader attachment. There should be another tag for the crawler itself. I believe the...

If you bolt it, I think you need to find bolts that are at least size for size to the holes or maybe a .001" interference so no movement can get started between the hub and gear.

My experience with ring and pinion gears has been in heavy trucks and a loader or two. Those were sold, and we replaced them, as matching sets. Never had to do a crawler, but the parts are the same. In the parts catalog it looks like as a set, was the way JD sold them as well. Mating fits of the gea...

AS a follow up; I took a look at the 2030 operator's manual about servicing that filter and the instructions for the gasket are to install it in the transmission case (housing base) first, then install the element and cover. If you have the 555 operator's manual you might see if it says similar.

I can't help much beyond saying I looked through My Nortrax and found the part number as T34716AM. It shows as: diaphragm, Non John Deere parts, available to order. Send Lavoy an email at postmaster@jdcrawlers.com , he might have a source to get one, or ideas of where to check.

Good evening, I just went out and checked the JD gaskets I have on a 2030 filter cover I swapped out for one with a port in it (had to have one with a port in it for oil return from the front end loader we installed). The fit is about the same as shown in your photo. I actually stick the gasket up i...

The check valve should be the fitting where the return line connects to the injection pump.

There should be a type section on the engine tag before the serial number which identifies the engine, which may help. If you can see where the tag was mounted on the front of the seat panel it should be a straight 450 or an early 450B (s/n 142199 or before). According to JD parts catalog info the t...

Good evening, Just to clarify. You are looking for a procedure to adjust the set screw in the steering clutch brake drum (item 4 in the photo)? http://jdcrawlers.lcent.com:8000/johndeere/albums/userpics/10023/normal_450C_Steering_Clutch.GIF I looked in my E series manual and found the following in t...

Have you checked to see that the return line to the tank is clear? That includes removing the check valve fitting from the injection pump and seeing if it has foreign material looking like mouse turds in it. You can remove the timing window cover and check for debris there as well. If you find that ...

Is the loader valve like a lot of others and needs a "power beyond" sleeve put into the valve to send pressurized oil to the backhoe valve?

Hello Mark, Your 450C questions should be in the forum for the Late Model Crawlers, Lavoy may move it over when he see this post. It will get more attention from people who are more familiar with the new crawlers over there. Have you checked the serial number and are you are sure it is an actual "C"...

Have you looked at the parts catalog (PC922 if it is a straight 450) for your machine? I don't see kits listed only the individual parts. It appears there are a couple different sealing options based on the machine's serial number, and possibly if the adjuster was ever replaced. For serial number 64...

I have stuck the gasket up in the housing with grease as well at times, also with no problems/leaks. I think the OD of the gasket to the housing might be a bit tighter fit than on the can. But that might be a challenge from where you describe it is located. Just curious do you have the JD gasket or ...

If I looked at the right one in the parts catalog, it is the same filter (AR75603) and gasket (R43733) as the transmission filter on 2030 wheel tractors. The can is a different number but it looks like the same arrangement. The gasket sets on the land around the lip on the can. I stick the gasket to...
