rear end brake problems

[tomcase580b]

That's about all I can do... the more I think about that rivet, the more I think it was the original problem. There is an awful lot of room between the ring gear and the housing. Nothing could have wedged in there and caused that rivet to shear off. The fact that It has a huge tooth mark right in the side of it, seems evident to me that it failed and fell right into the side gear causing all of the side gear teeth to shear off....I'll post pics once I get it all back together...then maybe a video of it running... as long as I don't blow it up again...

First I gotta thank you DJ54… You were such a huge help… I couldn't have done this without your guidance…

Here's what I've learned.

1.) The diffy / rear end was broken when I got the tractor last April. The knocking noise I heard when the rear warmed up was probably a broken or few broken teeth on that side gear. It probably broke a tooth or two when that rivet failed, and one of those broken teeth or the rivet finally got up in the gear oil and found their way into the side gear and blew it up the rest of the way.

2.) The slight gear oil leak that I had on the right side (which is still present) Is leaking past the seal on the other side gear into the right brake assembly. I have and had no right brakes. still dont…lol that's ok thats another fix.

3.) Since putting everything back together…no knocking…and…here is the kicker…the machine is fast…and has way more torque / power than before….If I actually had a clue what this thing was supposed to feel like I would have known something was wrong in the beginning. I thought she was just old… And to think all the work I did over the last year with her limping along…it's amazing.

When and if the video that I took ever emails itself to my computer, I will post it here…It's taking forever…I may be able to do it on Monday when I go to work…My home computer is an apple and my phone is an android…they don't play well together…I'm not good at I.T. stuff either…But now I'm a Tractor Mechanic…Thanks Again DJ54

No problem..!! That's what we're all here for. You did the hard part, I just "arm chaired" it, with a few tips, LOL... Now that you've gained that experience, you can pass it on to someone one else of these days. Nothing like the satisfaction of fixing something yourself. And besides, saved yourself a lot of money doing it yourself.

And after that, doing the seal on the shaft ought to seem like a piece of cake... There is another thread on doing the brakes on a 580 on here recently. Didn't know if you saw what I posted on it or not, about boiling the gear lube out of the brake discs.

Also, if you use that parts book online, and get the seal number, you can cross it through NAPA online. Once you get that number, you can search for it here: JBR 17 LLC, Copy the number from the NAPA site, and paste it in the search block at top left. Their price is about half of what NAPA charges. Of course, it may not be worth it for just one, when you consider shipping.

Glad you got 'er going... Enjoy..!!

Hey DJ I have a question for you. The tractor has been running great the last few days. Yesterday after a full days work, I checked all of the fluids in prep for today's storm. I ended up putting 4 quarts of hydraulic fluid in the transmission, because I couldn't tell if it was full or not. I didn't check it with the engine running and in neutral. Anyway this morning I was having a lag when engaging from reverse to forward and back. a few seconds sometimes. When I was running at a good clip it was fine, but if I stopped the tractor to empty the bucket, and went to back up, it would lag again. Do you think this has to do with the fluid I put in...If I have 20 quarts instead of 16... I plan on draining it tonight to see how much I have in there. I should mention that I have no external leaks from that area.

I don't think having too much fluid would cause that.

Does it have the clutch cut out switch on the dash..?? My 480 does, but thinking some of the later 580's had it on the wobble stick type loader control. Not sure if you have dual control's for the loader like mine or not.

If it does have it either place, and it's on..., when you press the brake pedal, it will cut out the drive, allowing you to throttle up to work the loader.

It's also a good idea to come to a complete stop, before changing direction, if you aren't already.

Hmmm.... I don't think I have the cut out switch... New problem I guess... I'll have to see how it goes

unless i'm having a problem with the brakes....it was crazy cold...If I do have the clutch cut out switch, and the brakes were sticking because of snow or cold, then that makes sense. And I did recently adjust the brakes after putting everything back together when I did the diffy...

 

[DJ54]

Well, if it's real cold, yeah that 90wt. would be like molasses, and will take a lot of movement to get it warmed up.

 

[tomcase580b]

More i think about it the more I think you are right... It's probably the clutch cut out... I always wondered y I didn't lunge forward when giving throttled when having the brakes applied.... I usually put it in neutrals... But if I forgot. It never lunged forward... I'm thinking the switch is sticking a bit because of the cold or maybe it's just failing... I'll check for it later
