Case 580B Shuttle Rebuild Kit

[Joseph Yarbrough]

I recently acquired a 1976 Case 580B. I believe it is equipped with a 188D.

I've been trying to find a shuttle rebuild kit for the 580B. I have been unable to locate such.

I'm only finding kits for the 580C and later models. So, would a 580C kit work? Was the 580B kit phased out, possibly being replaced by a later model kit?

Thanks.

Welcome to HEF @Joseph Yarbrough
A 580C shuttle kit definitely will not work.
580B shuttle kits (there were a few different ones that you needed to carry out a rebuild - seal,bearing,valve) are mostly obsolete & you will need to purchase individual items from your friendly Case CNH dealer

Looks like Dales got another customer..lol

Well, not only all of the above, BUT, the tractor came with TWO different shuttles. You need to know which one you have before you order parts. To the best of my knowledge you have to take off the shuttle-shift valve and cover to actually see. That's why I haven't done mine yet.

Are you absolutely sure you need to rebuild? I'm sure you have read all of the threads on this forum about pickup screen blockage and debris...right?

What is the backhoe doing, is it weak in pulling in one direction only or in both directions? Have you checked oil level for shuttle? There are two different power shuttle assemblies for the 580b machines, Rockford and Twin Disc. The Rockford is a lot easier to rebuild than the Twin Disc, the easiest way to tell which you have is by pulling the top cover ( where shuttle dipstick is) and looking at clutch assembly. The Twin Disc will have a dump valve in the piston housing, all it is is a piston and spring assembly with a rollpin to hold it in. The Rockford will not have these and will have a narrower piston housing. Another question is how many gear levers do you have coming up through your floor plate?

All I know on the subject is that some 580B's have an R or a T stamped to the far right of the machine serial #. This serial# is attached to the steering column on the right side. This letter usually it indicates which shuttle you have, but they do get changed. Only way to know for sure is to remove the shuttle cover and look. Phil

Here's a quote from the HEF 580B expert - we miss Phil......

Is the 580B-CK the same as the 580CK as far as parts are concerned?

BTW, the pickup screen was totally blocked. I did find the forward needle bearing pins in the bottom of the case as well. I removed them and have a new needle bearing to install.

It is a Twin-Disc. Four gears.

That looks like a Rockford shuttle, can you post a side view pic?

 

[Joseph Yarbrough]

Would a Rockford shuttle have an identification plate ("Twin Disc, Inc.") rivited to the clutch itself?

The shuttle is a Rockford and is much simpler to rebuild than the Twin Disc. If you go to the Case parts web site www.partstore.casece.com you can look up the part numbers that you will need.

Can anyone tell me how (or which tool to use), to remove the retaining rings [circled in yellow] to replace the first bearing? Thanks.

You use your fingers Joseph
But it helps if you use a length of 3 or 4mm electrical wire to push against the hook ring to depress it into the groove a little further than out fat fingers can allow.

Got the bearing replaced and everything is back together.
