Sounds like a problematic issue with Cats then.

Experience I’ve seen with hydraulic pumps failing is, it usually sends trash throughout the rest of the hydraulic system. It’ll make its way into the drive motors and pumps along with inside cylinders and spool valves, filters and all lines.

But hey, good luck with your money pit basket case. And that thing in the ad has 11,000 hours on it. Scrap value is all it’s worth.

They’re very rarely sold around here. The ones I did sell got fucked up in no time. Operator would clamp onto something in the center of the bucket like a bolder or tree stump and bend the bottom of the bucket. Ain’t no fixing that once it’s done.

What are they good for anyway? They don’t have the capacity of a normal low profile dirt bucket. Useless is what they are.

The Bowex drive coupling is not exclusive to CAT....

I thought you were in this business?

⁣Torsionally stiff flange coupling for I. C.-engines BoWex FLE-PA

Torsionally stiff curved-tooth flange coupling. â torsionally rigid â compact dimensions â for I. C.-engines â combinable â axial, radial, angular compensation

I understood it as a bad pump not pump connection, my bad.

Deere used direct coupling as well but I’ve never seen a failure with it and I’ve been around a lot of machines

Only one I remember having an issue which was rare, was the old Deere 8875 big chassis skid steer loader. The chassis was made by new holland back then and used the same coupler in their big chassis machines. Deere used their 3 cylinder wet sleeved engines tho. The two drive motor pumps were mounted side by side with the hydraulic pump mounted top of one of them. The engine crankshaft turned the pumps over by a set of bull gears. I’ve seen a couple machines where the main gear came loose on the crankshaft. It would then take out the two pump drive gears and the pump shafts to then the pumps. Very expensive repair. It was rare but did happen and I’m sure new holland seen it too.

I’m not familiar with all of Cats mechanical problems other then when all they offered was the ASV track system. < that is a nightmare in our environment and $$$$$$$ to own.

Different style coupler but same principal. I just replaced one of this style in a Case skid steer due to someone replacing the pumps and not tightening the pump all the way down. They are all meant to fail and most all have hydraulic suction filters to prevent complete system contamination if there is a failure. Repair is still cheaper than a new machine.

That sounds complicated as hell for a skid class machine.

ASV is bullshit, I completely agree.:beer:

Filters only do their work after the trash ran its course through the system beyond the pump. Filters are kn the hydraulic return circuit before the reservoir tank.

This was the layout on them. The 8875 ran from around 1995 - 1998. At the time it was the strongest machine on the market besides the new holland. It had servo assist steering (power steering). Funny thing was, it would lift a pallet around 3,800 lbs of landscaping stone, today, Deeres smallest machine the 317G or P now, will lift full height a pallet of stone just over 4,000lbs.

This is the diagram of the old 8875 engine to pump gear drive setup. A photo of one of the drive motor pumps with a bull gear input drive on it.

Gonna have similar door opening as the old model but it doesn't look near as bad.

They're not going to get any cheaper there's no reason to...

A 265 is probably going to find its way to the farm in the next year.
Let us know if we need to go in another direction.

We've had some issues that I'd consider teething on a new model.

The only machine I've worked on so far I was really impressed with over the outgoing model.

If a fatal flaw shows up I'll let you know
 
I was cleaning up around my property in my Takuchi TL150 harley raking the driveways going thru the burn pile and the fucking alternator quit charging. Most likely just a loose connection at the alternator but i gotta get it ready for the stumping job next week, got my rental excavator lined up, 2009 Kobelco SK210 but no thumb. I hope its not a piece of shit

Edit: is that better?

We don't have a clue what the alternator failed on... :flipoff2::lmao:

my tl140 alternator quit last year, i pulled it off on the spring trip to Colorado. brought it back home to get another. well we put it in the vise, hooked up a set of jumper cables and spun it up with an impact. it loaded right down when i excited it. so i felt like a dumbass for pulling it. i figured i had a bad relay or something. i put it all back together and same thing, no charging. i start bumping on relays hoping one just stuck, nope. then checking all the fuses, nope. said fuck it and just manually excited it and went to work. i have been meaning to look at a wiring diagram to see where i need to check out next.
 
if they've started doing computer controlled alternators on equipment I'm going to laugh

fucking internal reg is the absolute peak of charging system technology, they went backwards when they started doing that "full-field the alt when coming to a stop to save 0.0000001cents of fuel" bullshit

Doesn't FCA have some models where the alt acts as a motor and assists the starter for their stop-start bullshit? :laughing:

The hour meter was tied into the alternator at one time

Welcome to 2024, Deere has 6R series tractors alternators on a LIN BUS
