Re: 555 Transmission Pressure

I went thru a problem on one this past summer. The problem I had was marginal oil pressure but functioning well just slow shifts. We were lucky enough to have one that was slightly burnt at the back. We were wrecking the machine so removed the loader and fuel & oil tank and got it running and moving...

Re: New Owner, in desperate need of guidance!

My concern is that your reverser bearings are bad. Is it leaking much oil between the engine and reverser?

Re: 1958 420 Battery

Hold the pedal down, fold the lid down and pull your battery out. Not a great design, battery placement did not improve until the 1010 / 2010 series. Try a 420 loader..

Re: 450B track loader valve plumbing

Your machine has a power beyond valve that supplies high pressure oil to the hoe and then returns it to the tank. The supply and return lines must remained hooked together or will blow up your pump. If you want to remove the lines you will need to remove the power beyond fitting on the valve and ins...

Re: 440 Parts.. In Alaska

If your coming down to Edmonton I have a home for it. We still sell a few Detroit motors every year and still have lots of parts.

Re: JD 550 ?

This looks like a relocate of the transmission filter. Is there a filer under the seat as well.

Re: Dozer purchase JD Dozer comparison/info

I’m a real fan of the G series Crawlers now that I’ve put some seat time on a 650G narrow pad with 5500 original hours. The extra weight and power over a 450C wide pad and 450G narrow pad we used previously is impressive. I’m cleaning up some deadfall / wind blow downs on 20 acres in conjunction wit...

Re: 450C hydraulic pump not turning

Your drive coupler is stripped. Pull your hard nose so you can check if your pump is spinning freely and if so replace the coupler. Will fit off your parts 350. Your pump should be the small / low volume one which is not very common. I believe there are 2-3 pump sizes available. We have lots of the ...

Re: Model/part # for the extend-a-hoe?

The hoe on the 450C is not a 9550, it is a predessor model with a single swing cylinder. Just got one in in pieces and now have it operational on a straight 450 loader. You could put in a diverted valve on one of the stabilizer functions for use on the extendahoe. The extendahoe is going to be very ...

Re: Diaphragm-operated clutch in JD 3325 winch

Can you post some pics of how your winch is mounted. I would have figured the deere winch would have been on the light side for a D3.

Re: 450C loader losing hydraulic power

The filter behind the front grill is for the transmission. Do you have a whining sound, which could be the couplers between the Backhoe and the crawler? Try unplugging and reconnecting. Try running without the Hoe and see if the problem persists. As it’s both the Backhoe and loader should not be the...

Re: How crazy an idea is...

Yes it’s a track pin press. Cylinder is about 10 inches in diameter with a 10 stroke. Has line up rings on both sides to accept heavy duty 1 inch rod with a backer plate that fits behind the link and attached with nuts front and rear. Will fit thru 350 and 450 links otherwise need to use it in the v...

Re: To buy or not to buy

For 4,500 I would already own it. Engine and Dozer assembly are worth that in Alberta Canada. You might get a functional 350 or 450 for $10K, but they are far and few between and will mostly likely need frame, cross member and/or track work. We are getting close to out of 350C and 450C parts as ever...

Re: 1010 roller rock guard

My dad is always fussy about the length of bolts used in the track frames. The original bolts are only long enough to make it thru the track frame. Longer bolts corrode and often twist off when you try and remove them down the road. Great to see your fixing it right. We always pull the track frame a...

Re: 350B reverser

All straight 450’s have a floor mount shifter, almost all are the normal shift under power HLR. There are some that came with a standard shift HLR, only seen one and its in our shed. On the last straight 450 Dozer we fixed, we installed the newer style shifter on the battery box as they are much nic...
