JDcrawlers Messageboard

Good morning Gaylonbuch,

You should post this over in the late model technical support board, that is where it will get the most views from the folks familiar with these later model crawlers, and likely more answers. After that you can do an edit to this post and delete it.

HTH, Best regards,

Jim

1. Leave the fuel cap loose while starting and checking this out, then loosen it occasionally when running until you get it replaced. The parts catalog for the cap shows pressure relief/vacuum break options in it. If the tank was pressurized, as you posted, I would say something there isn't working ...

Gearmatic was another brand that was common. People mounted many different winches, some off old wrecker trucks or other equipment, even made winches from rear axles. I have seen some that were neat installations and some were just plain scary. Carco and Hyster were others not as popular. They were ...

Hi gregjo1948, I believe he has a 450 or 450B. The steering clutches and brakes can be pulled without removing the final drive housing. Condensed version: Seat, tank, etc. removal is the same. You still have to break the track and remove the sprocket. The final drive pinion shaft has to be pulled ou...

You looking for new, used, or either? What general area of the country are you in? How far are you willing to travel or are you open to freight? Someone might have an idea for you, but no sense to throw out a bunch that don't fit your criteria.

Hi Nick, Your technical manual should have a diagnostic section for the transmission, and pressure checks, that would be a place to start. You may need to get another gauge to use for the testing. Going over all the linkage adjustments might be good as well. Hopefully someone will have more on this ...

You can find your parts catalog (PC921) at https://jdparts.deere.com/servlet/com.deere.u90.jdparts.view.publicservlets.HomeUnsigned?selectedMenu=JDPARTS_HOME&userAction=countrySelected&country=US&language=19 . Put 350 in the model box, hit search, then pick the 350 crawler with your PC number from t...

bdbundy35, To get your post away from the 2016 one you posted your issue on (http://www.jdcrawlers.com/messageboard/viewtopic.php?f=8&t=10786); I have started this one to continue your problem on. Have you had a chance to look closely at your pump drive as a follow up to the previous posts? Does it ...

Hi dtoots1, Hope all is well with you, and your 440IC. This is a "trick" one, two different posters. bobdoss made his one post about his loader in May of 2016 (no follow up on it) and hasn't posted since August of 2016. bdbundy35 tagged on to it last Thursday about the disconnect on his dozer, every...

You still haven't said you have checked to see if the hydraulic pump shaft is turning, either with the engine running as NWJD fan suggested or by trying to turn the actual hydraulic pump shaft by hand (pliers, etc.) with it stopped. It might be something else, but you need to know the pump is turnin...

Send Lavoy and email at postmaster@jdcrawlers.com . He posted just last week that he has the proper bearing kits for the finals, http://www.jdcrawlers.com/messageboard/viewtopic.php?f=3&t=12636 . If your tracks are original to a 420 you are looking for a pin with a head on the inside of the track ch...

Hi dtoots1, That long shaft is the propeller shaft between the clutch and reverser. The rod beside it is the clutch rod between the clutch pedal shaft and throwout bearing carrier. It is a bit confusing as it is upside down, pretty easy and common to end up that way when trying to navigate a boresco...

Just asking some questions to get all the info clear, since we can't see what you are looking at. What is your serial number? Was it working when you got the dozer and quit after working a while? I only ask as you saying it is missing the splined coupling and lever. I take that to mean the sliding c...

A number of parts are, or may be, compatible. You can study both parts books at the link I posted before. There are serial number breaks in both series so that adds to what might or might not be compatible. To me it depends on if you are looking for specific parts you know you need, or if you just w...

As for a manual. The 420/430 service manual (both in the same manual) SM2019 refers to the 40 series manual (SM2013) for some info. Send Lavoy an email at postmaster@jdcrawlers.com , he can help you out and be sure you get the info you need. The operator's manual is OM T42757. You can access the par...
