Ok. New, used, adjusted or not has gotten mixed between the engine and steering clutches here. Engine clutch is new with new pilot and throwout bearings as I understand you now. Finger height could be off if it was not adjusted to the set gauge. The new pressure plate should have just one coil sprin...

Using the Technical manual TM1115 for the 350C, have you checked, and made where needed, every steering and brake measurement/adjustment, on both sides, in the order laid out in the manual? If not, I would say start by doing that, not just going by the looks and feel of things. I believe the wet bra...

I feel lucky (saying that should change things). We've only had a few mornings below 0F so far this year and the days have gotten up into the low teens at least. Wind chills have been a bit rough at times. Right now its +28 and spitting snow at times. Snow, sleet, possible rain and Icing expected th...

Besides what Lavoy posted, I'd say if run with no free play, I would expect the clutch disc is worn, or burnt/glazed, as well the pressure plate. I would expect to be replacing clutch disc, pressure plate, throwout and pilot bearings, and adjusting with the JD7 gauge. When doing the clutch, look for...

I don't have that one to look through. Strange, but not uncommon there is no info, or it may be buried in a section on something other than transmission overhaul. It appears the early 450Bs had that same shifter set up. There is some info about adjusting both shifters in the 450B manual TM1033. Ther...

Just some thoughts, in case no one comes along with a 440ICD schematic for you. Do you have the parts book for your 440ICD? It shows the fuses, breakers, gauges, and switches/sending units you should have. (Here is a link to the one on line if you don't https://partscatalog.deere.com/jdrc/navigation...

Having to wiggle it to find neutral sounds like wear/play in the linkage. Check all pins and joints. The turnbuckle would be the adjustment point, if it is the only adjustable place in the linkage. What book do you have?

Welcome The E7450 number is just for the loader attachment. The loaders had separate model and serial numbers from the crawlers, during those years. The engine number is good to have but won't work either to get the year either. On a straight 450 the crawler serial number tag you need the numbers fr...

There's one in this post that might help you. viewtopic.php?t=1816

Is this still a 6 volt positive ground system with generator and the saddle mount starter switch on the starter? Is the wiring correct for a 420 or has it been modified? Things get changed over the years and I just want to be sure of what you have before guessing at what it is.

Lavoy, someone will correct me if I'm wrong on this. I see the adjustment of the pressure plate fingers as setting them at the proper starting height to get the maximum clutch life and adjustment as the clutch wears. As the disc wears the fingers get higher. This explains why you have to adjust peda...

To your question about setting the pressure plate on the main (engine) clutch. Yes you could have an issue there if it was not set. At the time a disc and pressure plate are installed the finger height is supposed to be set with the JD7 gauge. JD7 is the same gauge used for the steering clutches but...

The supplier is easy. Contact Lavoy by email (postmaster@jdcrawlers.com) or phone (701-361-1006 during central time zone business hours). His business provides this site for us to use.

I am guessing you are talking about the inboard bearing on the axle shaft. the cap is visible when you are under the crawler. I can't say for sure if you can get it off in place and then make the adjustment or not. I will say you are there, hands on, to try it if you want. If it doesn't work out you...

Yes, your crawler is a 1967 build by that number. Machine serial number tag breakdown using the 350 Introduction from the JD parts Catalog: SN = serial number T = Tractor 4 = JD350 E = Crawler - Loader 3 = Diesel D = (Transmission) Sliding Gear with Reverser Serial number: 047766 (This number falls ...
