Re: I got the power...

Amazon says silicone rings are quite the thing.

I never knew they existed and now I want one. I gotta quit coming here.

My wife gets mad because I don't wear my ring while working. Then I show her a picture of ol' 9 fingered Clyde...

Youtube 350 final drive vid

There is a YT vid about a person removing a 350 final drive by cutting the outer roller rail so it could slide out. It was painful to watch.

I could put a link if anyone is interested but it comes up easily on a search.

It's not anyone here is it?

Re: HLR pressure gauge.

I, for one, do not want a high-pressure high-temperature oil line, down around my feet, pointing upward, to fail. Just no.

Re: HLR pressure gauge.

I think mine might have had a transmission oil temperature gauge, or so the manual says.

Re: JD 450C final drive sprocket bearings

Have a spare master pin if you can find one. Sometimes they 'resist' coming out and require 'persuasion'.

ETA: My final drive was leaking because whoever had put the 5/8 bolts in, didn't torque them. Wasn't their only mistake assembling it but it was one of the larger ones.

Re: JD 450C final drive sprocket bearings

Do you mean the bull gear bearings?

I've had the right final drive housing off mine. R&R'ing the track was the tough part.

Re: 450C HLR diag question

Hi Joe, Thanks, more coffee now. I see that now in describing a soft shift, passing thru neutral with R->H and H->R. My question, a bit more refined by caffeine, is with the valve positioning of HLR in the N detent position. From what I can see, the shift valve is in transit between R<->H and the pi...

Re: 450C HLR diag question

Hi Joe,

Thanks for the insight, I've been here ruminating about what you said.

One thing I just noticed about the manual and maybe it's me being not awake yet is: there is no description of valve positioning or oil flow when the HLR is in neutral.

Its not dumping out the pilot valve is it?

Re: 450C HLR diag question

It hasn't gotten any better, if anyone is wondering. And I know you are. Or were. It's an odd little thing. It intermittently fails to engage low and mostly when shifting directly from neutral. I dug out an alder stump for a bit of exercise and it didn't change for better or worse. If it fails when ...

Re: reverser oil flow question

It could have been a replacement cooler that was stored somewhere accessible by Rocky the flying squirrel.

I think one could duplicate almost any weird condition with a handful of crushed acorns and some blue goo chunks.

Re: reverser oil flow question

That might help explain the weird clutch behavior. (notice how I hedge that statement :) ) If it blocks the check valve closed, it starves the needle valve. If it blocks the valve open, it dumps high-pressure oil from the accumulator et al. People tend to use about 97% too much blue goo when assembl...

Re: reverser oil flow question

You have a secret squirrel. Or someone used to have one.

A better question might be: How many acorns are there?
