Re: Seeking advice on replacing high pressure hydraulic line in a 450B

I have a 450B track loader. The low-pressure return line on mine is two-piece, with a rubber coupling connecting the two. A hydraulic shop was able to provide me with a 6” length of oil resistant hose. The high pressure lines on mine had a bad spot. I was able to thoroughly clean and braze the worn ...

Re: 450B power steering pump

Thanks for the suggestion.
My B uses the Fluid from the tranny for steering pump.
Changing to HyGard made for immediate improvement.
Didn’t want to risk damaging tranny using 303.

Re: 450B fluid types

JimB, You posted great info. Another forum recently posted a similar thread about 303. Described a lawsuit that exposed same- not a valid standard and basically bottling what’s mopped up off the floor. Wish you guys had posted this 6 mo this ago! Had changed my tranny screen and fluid and thought wa...

Re: 450B power steering pump

So, I know this thread has caused much debate. I thought I’d follow up. Figuring I was being conscientious, I had replaced tranny screen and fluid. Manual calls for 303 so used that. After is when I noticed rapid pulsing in steering levers when pulling back- in gear or neutral. Read in another forum...

Re: 450 steering brake adjustment

Sounds like maybe your steering clutch isn’t releasing and the brake is doing your steering while the clutch is still allowing power to the right (lugging the engine). Maybe try pulling both steering levers back partway- If both steering clutches disengage, you should stop moving. If you start movin...

450B power steering pump

So, gonna test my power steering pump pressure per manual with a gauge but, thought I’d see if anyone has an idea what I have going on. 450B with power steering pump that doesn’t have reservoir- uses fluid from transmission. When pulling on steering levers, there is a rapid pulsing felt in the handl...

re: turbo oil line, oil pressure sending unit fitting.
My 450B has it mounted on the forward bolt on the fuel filter mount.

Re: A “Thank you” for Lavoy and Inj pump question

Thanks.
You guys have given me a couple things to try.

Weather still hit and miss so will see how she does when actually working this spring and try some of the diagnostics suggested.

Re: A “Thank you” for Lavoy and Inj pump question

Certainly worth trying. Thanks guys. I’d left the #2 line loose and cranked to bleed when all new injectors in. When running, had to tighten a couple others that were weeping. Haven’t put under load but, don’t hear a miss and didn’t have a miss while working previously. I just thought it odd that I ...

Re: A “Thank you” for Lavoy and Inj pump question

I appreciate the reply.
Should have mentioned: had the valve cover off last summer to check clearances- they all were within spec.
This girl has seen some use and little love in previous life.
I’ve been chipping away at stuff without tearing into her like the beautiful job Oldmetalmender is doing.

A “Thank you” for Lavoy and Inj pump question

First, I want to thank Lavoy for fixing me up with new injectors for my 450B. Very reasonable price and they came adjusted and ready to install. The hardest part of the job was getting the dang new rubber washers down inside the nuts for the return caps far enough to get threads to engage! I’d origi...

Re: What is in a JD350 fuel tank

Thanks for the great pics and info Stan!
Had the issue with plugged vent on my 450B.
I fumbled along and finally found the vent. It’s nice to have this for others to reference.

Re: JD 350B Steel Hydraulic line

I have a 450B. I had some damaged hard lines. Maybe I was lucky but, I was able to braze one section- used flux and built up a layer. Also, had some crushed sections I was able to splice in replacement tube. If yours is leaking on a straight section- maybe cut out that section? I cleaned lines with ...

Re: Tilting Hard nose on 450c dozer

I have a 450B trackloader.
As well as the filter mount, I had to raise limb risers and remove belly pan. Then, it’s just the two bolts on each side.
I had the loader raised so, was able to use that and a come-along to support hard nose.
I completely removed mine for radiator and water pump repair.
