JDcrawlers Messageboard

I would start by doing the easy things first. Do every adjustment for the clutch, clutch valve and HLR by the book and in the order given. Check the linkages closely, something may be worn out or loose as well as out of adjustment. Next after that would be looking for a hang up in the hydraulics of ...

Jason,

On line T24778 appears to be a drawing number now. SN 142199 and prior use cylinder AT21866 - NLA, SN 142200 and up use AT36885 - NLA. The Kit for both cylinders is AT27076 and that shows as a good number in the $50.00 plus range.

Apparently JDParts will be making some changes again this year, see the note in the sign in box of the photo below. This message, about access to JDParts being stopped in 2020, started appearing a couple weeks ago when I signed in. The way it reads we will still have access to the catalogs but for t...

U10438 (most suffixes are dropped with the current JD numbering system) shows as No Longer Available. I don't think you meant U10428, but shows as a Tee fitting costing $70 to $85 depending on the dealer, but I did not find it shown for a 1010. A used cylinder or rod with the end on it, adapting som...

The service manual for the 1010 crawlers is John Deere part number SM2034. That is the publication number to look for whether you look at used originals or reprints on eBay or other sources. Jensales is another some are avoiding as well. They are selling reprints of the I&T manuals as the service ma...

In case you don't have a parts catalog or a link to it on line; here is the link: https://partscatalog.deere.com/jdrc/navigation/equipment/77299 . That will at least allow you to see the parts that should be there. A service manual is what you really need to guide you through the set up and adjustme...

It looks like the JD part number is R68281 for the bulk hose used to make those fuel return hoses. It says it has an ID of 0.156" (5/32") or 4mm. Any hose used needs to be rated for fuel oil service. Pressure will be minimal as it is an open return to the tank.

Just to rule it out, while you have it drained again, you might want to try suspending the thermostat in a pot of water and heating it. Watch the temperature of the water with a thermometer as you heat it up. It should start to open within a couple degrees of the design temperature and be full open ...

It wasn't overheating prior to the water pump failure was it? You didn't get it way hot when the pump failed did you? If the pump is the only thing changed, I would install the rebuilt pump. Do you have the right gasket(s) for it? Did you change the thermostat? Is it possible you slipped and got it ...

Paint on the belt faces of the pulley isn't going to help you. It may embed into the belt, cause dragging during adjusting, and increase slippage when running. If the pulley was backed way off it may take several adjustments to get the belt to work its way up to where it is running right and stays t...

The fan needs to be flipped if you haven't done that yet, it will not work correctly if turned the wrong way. The leading edge needs to cut into the air and scoop air back along the cupped curve of the blade. If you are setting in the seat looking at the fan, it turns counterclockwise. The belt shou...

If you can get the pins out of the blade lift cylinder(s), you can remove the cylinder(s), put the pins back in, jack the blade up and use a chain (run in a loop) between the pins (on one or both sides) in place of the cylinder(s) to hold the blade up.

You didn't say if it is a dozer or a loader, so I am guessing it is a dozer. As oldmetalmender mentioned use the manual. You say you don't have a reference book, aka service or technical manual, now is the time to get one. As mentioned there is more to check than just a few bolt torques, when replac...

Thre are some pictures in this post about a 420. The problem is they were in Photobucket, so are blurred. viewtopic.php?f=1&t=4390&p=20891&hilit= ... ket#p20891

Straps are definitely wrong for your application. This John Deere site has some drawbar pull info. https://www.deere.com/en/dozers/non-current-models/ It appears the drawbar pull is only shown for dozers, not the loaders. The 450G TC dozer shows a bit over 24,000 lbs. maximum. That will be affected ...
