Panzers: I break rocks thread

These two have a factory recall that needs to be done. 46 hours of welding on the main tube.

The main tube between the bowl and the rear frame?

Is that a fuel tank on the 627?

The 637's in the 90's had the fuel tank in the main tube with no liner. That joint would crack and fill up the rear frame rails, then weep out the small drain holes until they plugged up.
 
That one with grade control might have auto load
The new keypads are awesome, you put the display in help mode and press a button and it tells you what the button does.

I don't think they do that anymore, they have plastic tanks now on the rear of the bowl and down in the rear of the push block on the single engine machines.

Worst transmission in CAT history I bet. When the FEA looked like it would work in the simulation...

Any of the cat wiggle wagons any good? I know the local landfill contractor stocks reman trannys for their fleet.
 
Panz, do you run those chains on your loader tires? Saw the pic that Linkslide posted of that loader and made me wonder if you did that as well.

Nah. They are for the big loaders that live in the quarries. Only place that uses them near me is in the 3m pit.

They were before this transmission bullshit.
The CX38 9 speed is one of those transmissions like a Ford 5r110, they added gears to existing design and use electronics to control gear shifts.
This is sort of like in a motor grader when you FEEL those huge shifts every 4th gear. Instead of just applying a clutch to increase shaft speed there are some clutches that have to release then the next clutch has to apply, perfectly timed to pickup the load.
They also combined some assembly tolerances and processes that make it near impossible to build the trans with any reliability, even CAT Reman has trouble perfecting the process.

This transmission deal is the biggest SERIOUS fuckup I have ever seen from CAT.

Over $35mil across to 745C serial number breaks in warranty payments...
 
sounds like they should flash the clutch-clutch shifts out of it and deal with having a few less ratios

They can't based on the power flow, it would have too big of gaps.

The thing that really sucks is that transmission is a first class suck to remove. It's a mess of pumps and hydraulic lines over and around the transmission.

It's a 40 hour job to r&I depending on level of contamination.

Glad I don't have that shit in my wheelhouse.

On Deere transmissions the single clutch to clutch gear changes were smooth as silk but when multiple clutch's had to disengage and multiple others engage is when we had shifting complaints. Deere's newest e23 tractor transmission is one of the best shifting ones out there long as the controller doesn't try to engage two gears at once and stall the engine while moving @ 5 mph. Spun the fan clutch right off the end of the fan drive gearbox when it stalled the engine.
 
Got another project. Another thin bucket to work on.

Dog bone also needs some attention. I could not believe how bad that was. Hard to believe that there wasn’t more slop in the bucket.

I’ll bore it out in the Bridgeport and weld it back up to size.

What material do you use for the cutting edge, wrapper and side bars?

Man a 5 year cliff hanger. I don’t know if we can wait that long lol.

We just put down some hard facing on the edges. It got worn down a bit in the center. The cutting edge is just a standard pig iron cutting edge. Got a set of carbide infused edges coming for this guy. Should get 2x -3x the wear out of the edge with those

I signed a pretty restrictive contract, and Cat is my biggest customer by far. I really don't want to piss them off while they let me do fun and interesting design and development projects. I'd have to get a real job and I'm too old to deal with corporate bullshit every day.

I will leave this teaser.......Back in the mid to late 2000's engineering wasn't run by engineering. Coupled with early retirement incentives to get rid of the old timers led to some really stupid decisions. Most of those decisions didn't make it to production but a few did.

Those old timers could have saved Billions of dollars if they were still there. I got a front row seat to a couple of the really stupid ones that slipped through the cracks. When the SHTF I hired a few of those old timers to fix problems their replacements created. In most cases those guys were my mentors in my early years. They taught me more in a couple months than any professor I had in college.

Someone on here will remember that post and remind me. I'll be happy to share then.

One thing about Cat and outside contractors. You never know day to day when they'll pull the plug. But it's always an emergency when they call to restart the project because it's already 6 months behind schedule.

but you just said that they got more gears out of an existing transmission by adding in clutch-clutch shifts, like the 5r110 did outta the 4r100 hard parts or the TCM 6spd 4l80e

just ditch those additional ranges and have the "old model" with a four speed or whatever they had before
 
Got some time this afternoon to work on that dog bone. I had one of the guys build up one side of the face with weld so I could straighten it out.

Tossed it on the old Bridgeport and hammered it smooth. I really like this fly cutter makes quick work of shit like this.

Part of the deal with the cat guys was they were gonna use my welder to fix those scrapers up because we only have 220 single phase. Well the shopmaster didn’t have enough snort to push the air arc. So I dug out a 600 amp lincoln I haven’t used in 8-10 years.
D898C6C9-5332-4DBF-A81A-1D1277C009F6.jpeg

Plugged her into the 460 off the phase perfect the crane runs off. She purred like a kitten tossing 400 amps down all day.

They got both machines all cut up and ready for the patches tomorrow.
