    580M Boom and Dipper Operation

    Real operators would be horrified at my excavating lol. I bought the 580M for digging a new creek channel ¼ mile long on my farm. The backhoe took care of the trees and roots while the finish work was done with a tracked loader and dozer. I think the control issue has developed slowly over a...

    580M Boom and Dipper Operation

    Boom won't work with anything else. I've been ignorantly running it like this for several years. A neighbor bud with a 580SM pointed it out. His machine was on a job so he borrowed mine to bury a cow and pointed it out.

    580M Boom and Dipper Operation

    I’ve only operated two backhoes in my life, and old Ford and my Case 580M. On neither of these could you raise the boom and retract the dipper at the same time like you can on an excavator. If you’re raising the boom and try to retract the dipper the boom stops. I’m told newer Case machines...

    Where does the transmission fluid disappear?

    On my 580M one of the brakes leaks by a little which causes THF to build up in the differential. I check the level and drain the excess every 20 hours or so. The THF from the brakes on the 580M comes from the main tank, not the transmission. On the JD, is the THF for the transmission...

    580M Dipper Bushing Replacement

    Welder Dave, yes pump is a 10000PSIG. I call it a 10-ton as that what Harbor Freight calls it and they also sell a "6-ton". The fittings in my link are all compatible with Enerpac for a fraction of the cost

    580M Dipper Bushing Replacement

    30T hollow ram; $175 they had a 20T for $50 less which would have been fine https://www.amazon.com/dp/B097G5FZ7Z?ref=ppx_yo2ov_dt_b_product_details&th=1 fittings $22 https://www.amazon.com/dp/B09YCSVPZ2?ref=ppx_yo2ov_dt_b_product_details&th=1 7/8"-9 B7 threaded rod $18...

    580M Dipper Bushing Replacement

    The 7/8" B7 rod with grade 8 nuts did the trick and I was able to pull both bushings out easily using my cobbled together apparatus. With my Harbor Freight 10-ton porta power, I used a 30T hollow ram from Amazon that had a female quick-connect coupling compatible with a Enerpac C-604 coupling...

    Case 580C Loader Bucket Interchangeability?

    A bud needs a front bucket for his 580C. Will a 580L or M bucket work?

    580M Dipper Bushing Replacement

    I got fittings and was able to adapt my hollow ram to my Harbor Freight portapower pump. I fabbed an adapter out of 1/2" plate with a bandsaw, grinder and dremel tool. I cut a 1/8" tall pilot boss that aligns it inside the bushing bore. It aint pretty but fits perfectly. I can insert it...

    580M Dipper Bushing Replacement

    You were on the money. If I have time tomorrow I’m going to take my porta power and hollow ram to the hydraulic shop and see if they have the fittings to make them connect. I’m sure I can fab a bushing puller that will fit. I’d like to pull it myself just for the experience.

    580M Dipper Bushing Replacement

    I just talked to a service tech at the Case dealer. They have a set of OTC bushing pullers that have two sides cut off. This enables it to slip inside and pull each bushing out. The threaded rod attaches to an air-powered OTC hollow ram. He said they can remove the bushings in less than an hour.

    580M Dipper Bushing Replacement

    There is gap between the dipper and the coupling of about .100". I've thought about cutting the 4" bushings with a portable bandsaw. This would simplify the job. I'm going to try and cut an old bushing with my mounted bandsaw and see how difficult it is to cut hardened bushings.

    580M Dipper Bushing Replacement

    I know all Case 580 K, L M and N are that way. The specs call for .007" clearance between the coupling bushing and the 4" bushing. The 4" bushing is the "pin" for the coupling bushing. I'm going to check with the local Case dealership and see how they do it. Honestly, when I tear this stuff...

    580M Dipper Bushing Replacement

    Hopefully this isn't too confusing. In my "diagram" the 4" long bushings are in black and the coupling bushings in red. The coupling has two bushings as shown. The dipper has two 4" long bushings pressed in on each side that extend into the coupling bushings. The ID of the coupling bushings...

    580M Dipper Bushing Replacement

    Anyone ever replace the two 1 ¾” ID x 4” long (approximate) bushings in the very last holes at the bucket end of the dipper (307186A1)? I’ve got a lot of slop either in the OD of these bushings or the ID of the big coupling bushings (D127167). I replaced all the other linkage pins/bushings last...

    580M Fan Belt Not Tracking

    Tensioner replacement - 15 minutes Tensioner and belt replacement - 3 hours A bad tensioner will destroy the belt. My Case 450C dozer has the same setup and I replaced the tensioner when it started getting slightly wiggly just because I didn't want to replace the belt.

    Radio Replacement

    Lot's of good but cheap options out there. I put a Boss 616UAB in my 580M two years ago. It was $25 bucks from Amazon and bluetooth.

    Front Backhoe tires. What brands are good / bad?

    I have the same size Carlisle Ultra Guards on my 580M and really like them. I bought them for $210 each three years ago on Amazon. The guy I buy my truck tires from mounted them for $30 each.

    Bearing Press

    I bought it. It came with about 50 discs in 1 mm increments. I've already used those twice with my arbor press.
