Re: JD450C - What engine do I have? Need to source filters

Hi Chris, Those are the filter numbers for a 450 direct from the parts catalog, unless I transposed a number. Like Bruce said I think your engine tag is missing, the attached photos is a 4276 engine but the tags are in the same location. I don't know if you can tell the difference in the 202 and 219...

Re: JD450 Hard Nose Removal

Safety first . If you are going to have your loader raised while you do this, use a safety support on at least one of the lift cylinder rams so it can't come down on you! If you don't currently have a support, get some heavy angle iron or have some 5/16" or 3/8" plate bent and make one. If your not...

Re: JD450C - What engine do I have? Need to source filters

Hi Chris, Here is the serial number breakdown by the book and a filter list. Machine serial number breakdown: T= Tractor 5= JD450 E= Crawler Loader 3= Diesel (This would be 202 cu.in. originally) M= Transmission (Hi-Lo-Reverse) Serial number: 075316 ( that number falls in the 1968 build range by the...

Re: 350c winch install

I don't have an answer for you but moving the cup on the tank doesn't sound right. I was under the impression they would bolt up if you have the right winch mounting adapters between the winch and crawler. Hopefully someone with a 3315 winch on a 350c will have the answer on this.

Re: JD450C - What engine do I have? Need to source filters

Welcome to the Board, This is a good group of folks and there is a lot of knowledge and experience here. Lavoy who owns this site works on JD crawlers, more the older ones than the current ones. He is a great resource and also sells parts and supplies for these machines. First thing is your serial n...

Re: JD350 Track adjuster rebuild

Short answer is yes it is rebuildable, the real question is what parts you really need. Just some thoughts as it doesn't seem that area would leak, seal leaks, I've seen, normally appear at the rod end. Have you cleaned the area well? Have you checked to see if the housing itself is cracked in that ...

Re: Single remote control valve

Do you have a parts catalog or use the free on-line parts catalogs at JDParts Homepage? You should also have the operator's and service manuals if you don't have those. I believe Lavoy can help you out on those as well.

Re: Single remote control valve

I honestly think you will find Lavoy will do the best by you. He knows those machines, he has parts that are quality, he installs them on machines in his shop and certainly isn't using parts that will give him come backs. If you have questions or things don't seem to be going together right he has t...

Re: Single remote control valve

Thermal Relief Valve - A valve which limits the pressure in a system caused by heat expansion of oil. I don't have a good answer for you. I would say it may be there to release if a valve is held in too long after movement of the function has stopped causing the oil to heat as it passes through the ...

Re: 450 Project

Right. Measure from the top of the pedal to a point in direction of travel, move the pedal until you feel it touch the throwout bearing and measure between the same points you used before and that is the free play travel.

Re: 450 Project

Good morning, A couple more questions to review. What do you currently have for free play at the clutch pedal? You say the clutch adjusting screw is bottomed out, or is it seized further down in the linkage from not being moved? Did you try turning it? It sets in a detent lock, as shown in your phot...

Re: 450 Project

Since you have the manuals I would say start by checking, and adjusting as needed, the engine clutch, the steering clutches/steering brakes, and foot brake. Eliminate the adjustments as the issue with any of those things. I think the key to the photo size when you post it is to be sure the img line ...

Re: 450 Project

Good morning, First things first, so the folks looking at this know for sure what model 450 you have. What is the full model and serial number from the machine's serial number tag? You say shuttle shift meaning the Hi-Lo-Reverse transmission correct? Inside or outside blade? These things may make a ...

Re: 40c steering pressure plate adjustments frozen

To work properly and get the best life they should be replaced. I wouldn't mess with a pressure plate that is seized up either. Its a fair bit of work, and it could be more expensive, to pull it back apart if the used and new parts don't play well together. Lavoy has a post "New lower prices on stee...

Re: Reuse fiber/steel plates for a 450?

I agree with Bruce,it's not worth the risk of early failure. Contact Lavoy, I believe he posted recently that he had the clutches for the 450s. He will have quality parts and if there is a problem he will be there to help solve it. We have heard of folks buying a ''deal", then having a problem only ...
