My first backhoe - 580B

[Phil]

Posting 2 diff lock pictures. Phil

 

[tresslers]

Thank you very much phil
the parts that I need are best shown in the second picture. They are the two levers on the left and the cross over bar. When I say left I refer to the pictures left not the machine left. I will try and get a post showing the parts I need with a circle over them.

On the diff lock I need the rod that goes through the floor with the clevis and the knob by the accelerator pedal. The lever is on the diff lock but there is no controls.

Ok in the first picture of the diff lock in the blue square I need this rod with the clevis and the pin etc.

On the second picture I need the knob in the green circle. I think this should be one piece.

On the third picture i need the the rod that is in the black circles. this is the main rod, you can't see it directly but it is under the other parts. I need the two levers in the red and blue circles.

Let me know if you guys can help
thanks

It is good to have the pictures to see what I am missing. The parts manuals are not as helpful as the actual pictures.

I also need an intake heater.

Is that a case only part or could i get that elsewhere?

I just purchased my first backhoe, a 1966 Case 530 CK. A little ugly cute right now. It needs a head gasket, or so the owner said. I figured for $2500.00 I could get that for parts if it is too bad. Doesn't appear to badly beaten up. Looking forward to getting it home to start. It will be used to clear our land in Haliburton. Funny thing is I have work offers already.
I may be doing some brain picking in the near future. I already have learned a fair bit by reading previous post.

Good luck with your new / old machine.
I just got a bunch of the pins that I ordered in.

I have ordered some brake parts hopefully I can get the machine so it will stop.

 

[tresslers]

Guys,
I got the brakes apart. It looks like there are new linings but i don't see how the brake disks are engaged. I can see how the bands work but is there supposed to be a way for the drum to press against the case?

I also have a problem with a transmission leak. There is transmission fluid leaking from the starter. The actual starter itself. Did anyone ever hear of this before. Any ideas why it would do that and how do i fix it.

Also I can't get the diff lock off of the brake housing. I have the 6 bolts removed but the diff lock housing is still solid on the brake housing. And can't get the brake housing clear of the machine. I have the 4 bolts removed. So i am stuck on the right side. I have the left side removed.

let me know if you guys can help
thanks

From what i have found i have to get the diff lock off of the brake housing before i can remove the brake housing.

How can i make sure the ramp and ball system is working inside the drum?

Any thoughts why my starter is leaking transmission fluid?

I will start again on it tomorrow as the machine is outside and it is cold.
From what i have seen the right side has an oil leak on the brakes. Which seals do i need to replace? Is it an o ring or a normal axle seal. Do i have to buy the seal from case?

thanks again

The brake band slows the drum from turning, and this forces the drum and disc apart horizontally, by action of the ball bearings rolling up the ramps inside the unit. Now the linings on the drum and rotor assembly are forced against the case and inner plate.The disc is driven by the spline on the differential carrier assembly, and of course wants to keep turning while the drum does not, once you slow it with the outer brake band. I hope I've explained somewhat clearly.

The 580CK and 580B with converter drive had a wet flywheel housing. Starters used in this application have to be used with a mounting gasket and an internal shaft seal. Failure of this seal can affect starter life/operation and leak oil.

The diff lock assembly has one socket head capscrew toward the cover front. It is hard to see and is flush. The brake cover should come off after that is removed if the loader frame has had the relief cut into it where it mounts on the axle housing.

To answer #48 post, I'm not sure how to bench test the drum/rotor assembly. I would certainly take it apart and inspect the ramps and balls for wear. Pretty simple device.

Common problem, leaking shaft seals. If oil gets on the lining, I would replace them. Get the shaft seal from Case and the o-ring too. There is a sleeve needed to help with the install. I believe it was Melben in an earlier thread who had the idea to adjust the brake up tight on the opposite side to avoid disturbing it's seal and cause a leak. Phil

Phil
How do I fix the seal? Is that a problem in the starter or do have have to split the engine and fix the transmission.

From what i have read i have to fix a seal in the starter? Is this correct and is it a problem to repair?

 

[Phil]

Sorry, should have explained that better. The seal I'm referring to is inside the starter, just behind the pinion. These starters are easy to take apart, or you could take it to a starter repair shop. They usually stock these seals either way you fix it. Phil

 

[tresslers]

Thanks Phil
I found the post from melben

"To keep the differential shaft on center while working on the opposite side I tighten the adjustment on the opposite side so the brake not worked on is applied , this centers the brake in the housing holding the shaft up in position. Also electrical tape wrapped on the splines and wrapping a few extra turns next to the area where the seal must expand works as well as anything, better in my opinion than the factory supplied sleeves. Been working on Case since 1962 full time so i've seen a few things."

I will see how far i can get tomorrow.

I got the diff lock off.
It was easy once I had removed the blind bolt that phil told me about. I also got the brake housing off.
I need to order the seal and the o-ring to fix the seal. I haven't seen the ball that is supposed to be in there.

Will it fall out? where do I look for it.

I also noticed that the lugnuts are on the wrong way. The crown part that is supposed to center the wheel is facing out. So i reversed those today as well.

So right now the list to do is
Fix the seal and bushing in the starter
Fix the electrical system
Fix the intake heater
Fix the tachometer
Fix the brakes
Fix the linkages, brakes and diff lock
Replace the filters Oil, Air, Hydraulic, Transmission, P fuel, S fuel, Rower steering (where is this filter located)
Replace pins
Reroute hoses
Replace rear tires
Replace lugs on the front tires
Fix seals on two cylinders the dipper and the boom

That is the list I have found so far
I will post as it goes.

I love a project and I have a really big one.

Thanks for the Welcome and the beer Cowboy.

I'm not sure about the ball you are talking about, unless it's the 4 balls that are inside the drum assembly. I have used a small slotted screwdriver to unhook the 2 springs holding the assembly together, also the same to reassemble it. I think I have one of these apart, as a spare, if you want a picture. I would replace both seals, in other words, reseal both sides, while you are at it.

The power steering filter is inside the reservoir. Remove the nut on the rear of the reservoir cover, to pull off. Replace the seal also, and put the cover back on with the same orientation.

Note: The shuttle/converter housing has 2 drain plugs. Phil

I got the brake drum apart.
I am going to clean them tomorrow and order the seals.
Then I can reassemble the brakes and can check that off the list.
I am now waiting on parts, it might be a day or two.

Phil, do you have a model number for your Sims cab? Just what the Dr. ordered for snow removal after install of Princess Auto heater.
