Case 580B shuttle pump...

Any adjustment u make be aware u might end up adjusting it wrong.

Are you talking about this one?

Yes

Watch as u rotate it the mechanism moves in and out.adjusting to 3.1 . Besure roller bearing fits in raceway good.

Ok, see I tightened that down all the way when I was messing with things. I bet I am very far out of adjustment, I will play with that when I get a chance and see what happens. I am currently out of town so it will be 2 weeks before I can do that.

From the 2 different pics for the tube clean out location looks like 3.5" from the edge of the 3/4" hole to the center of the bolt hole which is about 4" center then there is a pic showing 3" centers. Which would be most accurate to be in the middle of the suction tube?

I did 3.5 inches and 3 would have been better. I'll try to attach a picture. You won't believe the stuff you're going to pick off that screen. If your oil is contaminated you're going to use lots of oil (or diesel) whatever in order to get it clean. Even with cranking it and idling for a few seconds with the filter line off and running the old stuff through the lines and into a bucket till it runs clean you will still need to fill and dump the housing a few times till you get clean oil.

I think if you use 4", it may be too much. I can't say mine is exactly where it should be, but I can feel all around the screen with my finger. I drilled 3.5 inches from the middle hole using this picture. The Original Poster of the picture said he drilled his too short and is showing the 3.5" dimension as correct, even though the end of the tape isn't at the center of the bolt hole...

Its 3 inches

Large pipe taps are expensive but I would drill for at 1 inch minimum hole 1 1/2 inch even better.

Id think bigger is better but what about integrity. I think 3 inches is correct. Lots of talk on here about where and how to measure

Thanks a lot I drilled 3.5" centers and its good enough to clean it but the 3" would have been better on mine. Strainer was certainly dirty and got my hopes up but slips in forward bad, it cannot go up into garage but reverse is wonderful. The pressure is in the green except when you step on the clutch.

Does anyone sell a rebuild kit for the 580B shuttle? I am looking online but only see one for the C model and newer. Thanks

call Dale Weiss in Daleville Indiana. He is tractorstuff.com (765) 378-3396

Thank you, I will!

I agree. Bigger than the 3/4 pipe tap would be better. A 1 1/4 - 11.5 NPT tap drill is 1 31/64... (1.484), which would be perfect! Drills this size usually require a taper socket in a 3/4 drill. Not very plentiful. You may find a reduced shank drill to fit in a standard drill but you might burn up the drill. My 1/2" drill struggled with the 29/32 tap drill (.906). The cheapest tap on MSC is $56.11 plus shipping https://www.mscdirect.com/product/details/52358397. I imagine it would be difficult to start the tap as well.

I think the 3/4 NPT is probably the largest practical size with common tools most of us can find.

I don't remember where I bought my tap, but there is one on ebay.

Look at coleman equipment or call dale weiss

You can find clutch disc online after u get part numbers.coleman gives u those as well.

This is my first post on here. I have been a member for a year or so. I have been reading these posts on the 580Bs. I am an experienced mechanic. I serviced some of these old tractors when they were new. But never did any major work on them. I found this old tractor and bought it.
In the past I have drilled the clean out hole for the shuttle and cleaned the shuttle screen. The screen was incredibly dirty, flushed and changed the filter on everything.
After running the tractor for a while I noticed the oil pressure on the engine was going down to 0 at idle, when it got hot. Also I noticed the trans pressure getting low again. So I pulled the engine down and it needed rebuilding. It had a lot of sand in the bearings, which dated 11 and 12 of 72 on them. The crank was scared and needed rebuild. The engine is built now, and so I focused on the shuttle and decided to pull it while the engine was out. So when I got the tank and covers off it looks like it had been under water. The engine was full of slime and now the shuttle looks the same. So the shuttle is split out of the tractor and clutch pack is setting on my work bench. I believe this tractor might have went under water in the flood of 1998 in central Texas. With that said I believe the clutch stack needs rebuild and I cant find any info on the disassembly of the Twin Disc clutch pack. The clutches look good from the outside but I would like to replace the seals on the servos and make sure the slime is not in them.
I purchased the service manual that is on disc. But is very vague on any tear down. I do not want to make any mistakes on this, as I know that parts are hard to come by, and I see some little roll pins in the outer plates.
Can someone on here help me out. Thanks Earl
