This is a picture of a late 350 showing a tag. The serial number tag on a 450C should be in the same location, front panel of the battery box. If you have two 1/8" holes about 3 to 4 inches apart in that area, the serial number to identify the machine with has been removed. http://jdcrawlers.lcent.c...

Welcome to the board, to bad you're starting this way. First thing the engine serial number is not the main serial number you need. There should be a tag on the front of the battery box, right where you would see it when you get on the operator's station, That is the crawler serial number which is m...

I did a bit more digging on this and looked for a 350B service manual on line. I found one (pretty poor as I didn't want to buy it), but in a preview I can see it has basically the same notes in several places as the 2020 (4 cylinder) manual I have. To service the crank and main bearings, the engine...

I'm not following you when you refer to things being mounted to the under carriage. Are you doing this "in frame" or do you have the engine out? Been years since I was inside one of those. On a 4 cylinder you have to pretty much strip the front of the engine to get enough off to remove the front mai...

Well the original poster, Mikesloud hasn't signed in since July 21, 2021; so we don't know if he ever found the problem with his crawler or not.

Southern tagged on to this post looking for an engine and hasn't posted since.

You should be able to find several posts about fellows installing winches and what you have to check to see for internal drive line parts you need to add to your crawler to run the winch. You can also study the 350B parts catalog, it shows the 3315 winch and power shaft related to it. You 350B Techn...

Welcome to the Board. For future reference posts about 350s and newer should be on the Late Models Board. This post will likely get moved over there when Lavoy or a moderator sees it. From looking at the parts catalogs, they are not the same. besides the 555 show's just one water pump and the 555g c...

The 3320 (Manual control) was used on the 450, basically replaced by the 3325 (Power control {hydraulic pressure from a pump in the winch]). The 3315 is Power control. The mounting adapters (between the winch and crawler) for the 3315 and the 3320/3325 are different part numbers. The 3320 may fit an...

Paul and Buckhorn have given you correct info. I am guessing you don't have any manuals, which would explain adjusting the steering clutches and brakes. The 40C falls in with the older Ag tractors for JD manuals and because of that, you can actually download a pdf copy of the operator's manual, free...

I don't think having a bar across the links, under the snow hole, for a bolt would work well. The points of the sprockets come into that area.

Welcome to the board. There are two common places for diesel to get into the engine oil. First is the fuel transfer(aka Lift) pump. Next are the umbrella seals on the shaft that drives the injection pump. Transfer pumps are inexpensive and the common fix is to replace them, rather than try to rebuil...

Hard to say on the coolant leak, hands and eyes on the machine is the only way to confirm where it is.

The track adjuster is not spring loaded to retract. You are going to have to force it back. Don't loose the ball that is under the set screw.

Sounds like your right side steering clutch may be bad. When you pull the left lever to turn left it disengages the left side clutch, so the left side stops driving (in fact you stop it when you pull further back and apply the brake for a quicker turn). The right side continues to drive when the lef...

My thought is that the throwout bearing carrier at the outer end of it's travel means you have maximum available adjustment available in the future. As things wear the carrier/bearing will move deeper into the slot during adjustments, as the clutch discs get thinner and the pressure plate fingers ge...

The parts catalog shows the earlier units being subbed to the later unit parts including the T164040 shaft. Give Lavoy a call or send an email (postmaster@jdcrawlers.com), he might know of a good late model salvage yard.
