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 ...

If it helps here is a link to the online 40 parts catalog, open to the valve page, The part numbers are on the next page.

Google drive is his personal file share. It may have had a time limit on it, or he may have "closed" the files with the completion of his project.

Welcome to the Board. Just curious as to why you are looking for a 3305 winch. The 3315 Power winch was the one the 350Cs were generally equipped with and might be easier to find. Below is a link to the online parts catalog for the 350C which includes the winch, fairleads and tractor mounted arch. J...

Here are a couple pictures that may help you locate the crawler tag (or rivet holes where it used to be). Those will be two, 1/8" holes, about 3-4" apart horizontally. Where is your reverser lever located? The HLR lever moved from the floor (between the operator's legs to the left armrest at the sam...

Lavoy will likely move your post when he sees it. Don't worry about that, I just didn't want you to think it had been deleted if its not on this Board later. I expect the plate you found is on the dozer frame, right side upright maybe. That plate would be the ID/serial number plate for just the blad...

Welcome to the board. A bit of housekeeping. You should post about your 450 on the late models board as that is where models 350, 450 and newer are grouped. Not a problem, but you will likely find your post gets moved over there at some point, it didn't disappear. You say the tag is missing from bel...

Serial number is a 1977 450C with a 6405 blade (that's second C in the serial number).

Best bet is to check it out and keep the swap as a backup plan. Maybe you have a cylinder liner that has eroded through and is letting coolant into the base that way. Good Luck.

First thing is: Have you confirmed by serial number that it is a "C" series? cordlesscarpenter has a thread going about his 450B engine you should review. You may encounter some of the same or similar issues if you swap to a different series engine. I would advise finding out the condition of your e...

This is sounding like the mystery ball in a post about a year ago. Review the attached post and see if anything in it relates to yours. What does your front cover look like? Does it have the item key # 3, plug?

Welcome to the board. The ball and spring missing from the check valve is often a sign the pellethane ring inside the injection pump is breaking up, repair means a pump overhaul. When the ring breaks up it shows up as small bits, often referred to as mouse turds. They plug the check valve preventing...

Welcome to the board.

First question is do you have the technical manual TM1291 for it? There are adjustments related to the engine clutch and HLR clutch valve and you need the manual to set them right. Not saying that alone is the problem but could be a factor.
