JDcrawlers Messageboard

Yes the engine dangles on those 4 bolts along with the radiator and hydraulic pump which are mounted on a sub frame on the front of the engine. You can access the parts manuals for free online through the John Deere website to get a better idea of what you are dealing with.

Make sure your fuel tank is clean as well. My 350 would die on occasion for seemingly no good reason during the winter and it turned out to be a little ball of ice (could be anything foreign in the tank) that drifts close enough to the pickup and gets sucked over the opening but cannot pass. Engine ...

If having a functioning tach is your only concern there are some other options. Check out Tiny Tach online. It is a digital unit that senses fuel pressure pulses in one of your injector lines and creates a tach signal. Around $200.00 and non invasive. There are some other electric diesel tach option...

JD350B with 6 way dozer and ROPS canopy no rear mounted equipment weighs 10,600 pounds according to JD specs

Did you try a John Deere agricultural equipment dealer for the corn head grease? As previously mentioned the construction industrial and agricultural divisions of John Deere often don't have much knowledge of the other divisions product lines. Depending on how many old crawlers are around some const...

I welded grouser stock on my 350 loader pads with a Lincoln SP175 wire feeder and .035 flux core wire and it worked well. A 100 amp welder might be iffy but try a few and see. Might have to preheat a little or just rent a bigger welder for a day or 2.

I had a cracked valve segment on my 92 series hoe attachment on my 350 loader. No longer available from Deere but readily available from original manufacturer. Can't remember offhand if mine was Commercial or Custom valve company but the hydraulic shop I took it to had no trouble identifying and ord...

I did the same as Hodgiemoggy on my 350 loader except that my caulks were not as tall and all were same length and yes it does work very well in greasy and icy conditions and as Stan mentioned, much less welding.

Rather than welding full length strips of grouser material I caulked my loader pads using 3 inch long by 3/4 inch tall pieces of preformed grouser material purpose made for ice lugging on crawlers and it drastically improved my machines ability to get around in slippery conditions. I did every pad a...

If you go to jdpc.deere.com (John Deere online parts catalogue) and search your model of backhoe it will give you a parts breakdown. The model 92 hoe is actually for JD 300 and 400 industrial tractors but it uses the same mounting arrangement the crawlers do. Model 9250, 9300 and 9550 (and probably ...

Do you know what model of hoe you have. At one time there would have been a data plate somewhere on the boom. On my model 92 hoe the system relief is incorporated into one of valve segments that control the outriggers.

What kind of fluid are you using? The spec calls for JD Hygard, 303 or JD20A. Probably unlikely that this is your problem but I filled my straight 350 reverser with non spec hydraulic/drivetrain oil once and it was not very happy, jerky and rough shifting.

There must be an established ratio of hours used to days fixed that defines happiness or satisfaction or some delusional variation there of. I look at the 350C 6 way dozer with cracked steering clutch housing and asst stripped fasteners and think about how nice it manoeuvres in the bush and the grea...

When I drained my 450C I got approximately equal amounts from the transmission and both clutch housings combined. So be ready for about 10-11 gallons from the transmission 5 or 6 gallons from each clutch housing. My machine had 2 drain plugs on each clutch housing. The upper fwd plug drains a pocket...

Forgot to mention my 450C is 1980 model year with common sump.
