The loader quick coupler started weeping at the face last month. I changed the seal first because it was the cheap guess, but it still leaked after cleaning and reconnecting it. Once it was off, the poppet seat looked worn rather than dirty. I compared the thread, pressure rating, and seal material across a local hydraulic shop. The machine is on biodegradable hydraulic fluid, so I did not want to order by thread size alone. I have not pressure-tested the replacement yet. Before I put it back in service, is there anything else you would check on the female half or hose end?

Got a JCB merchant master tele truck. How much would replacing the 4 x boom hoses cost, roughly? They are the ones that travel inside the boom and go to tilt function

Been stuck trying to remove this cylinder for a couple days now, seems to be stuck inside the plungers. Last 2 pics are the “new” cylinder we’re putting in. Thinking of bringing the excavator down here and pulling it out with that as we have limited tools.
Any tips much appreciated

Anyone else built their own filter cart? I got about $400 in it total.

Edit: I just realized that I posted this twice (slow rural connection) so I deleted the second one.

Do y’all prefer older cat or wabco for scrapers?

Been looking at the equipment auction, planning on getting some. Couple of ex military Cats, as well as a 637. All mid 80’s. There were a couple of Wabco coming across the block as well, 70’s units mainly.

Have experience with old iron, our dozer is a late 70’s D9, our track loader is a 79 977

Bandsaw is 86" tall. Garage is 78". Last two times to move it we used a fridge dolly and 4 guys. Leaned over a lot to clear the garage and muscled it in side. I then ran and lowered the garage door to get it to close.

Using a tool to lean it over 45 degrees isnt enough, still too tall.

Any other ideas aside from just 4 strong guys again? If we did strong guy I'd ratchet strap a 4x4 somewhere to help. The cast iron top will be removed to cut 120lbs.

If I can just slowly lower onto a pallet I'd be fine. I'd figure out how to raise it up later.

Thought about strapping two 800lbs furniture dollies too BUT the tricky part is lowering and not dropping it and or crushing someone.

I thought haul truck at first glance but now I'm wondering if it's a wheel loader. Something like a 992 or bigger.

I've escorted up to a 773 haul truck which can be hauled on 4 axle lowboy. 992 required removing cab and wheels to move and was on 9 axle rail

This is my 1997 cat 16h, she aint new (56000 hours) but she’s well cared for. Every time i turn the key the 3406 purrs like a kitten and never throws a code to my face like the newer ones i’ve been in the past. Am i the only one to prefer older pre-electronic machinery? I don’t need a computer to work on it, i only need my trusty toolbox and the knowledge I gained by listening to experienced operators and mechanics. Been operating that same machine for six years and I wouldn’t trade it for anything else.

Midweek, deep into a pour schedule. EC210 showed low voltage on the dash, then the electronics started acting weird. Shut it down to check things and it wouldn't restart cleanly after that.

Alternator was completely dead. Locals had nothing, Volvo dealer was looking at a week-plus wait.

Found an aftermarket unit online by OEM number off the data plate. Ordered that evening, overnight shipping, on site next morning. Direct swap, same connector, charging looked healthy and we were back before lunch. First time ordering an alternator this way. Fitment confirmed by OEM number. Packaging was basic compared to dealer stuff, but it arrived intact and tested clean.

Real lesson wasn't the sourcing. I'd never been checking alternator output on scheduled service. Quick multimeter check would've caught the decline weeks earlier.

How do you all catch charging issues before failure on machines you run regularly?

Can anyone by any chance find M0172909-02? That's the 2026 maintenance manual for a HM810 Mulcher attachment to a Cat 308. I can only see 3 page previews. English is preferred but if you can find Spanish we can use that too.

The blades are supposed to spin quickly, but we're getting maybe 1/4 speed right now ever since we had it serviced due to a hose break. The hose that broke spilled oil everywhere, and the tech who services it seemed to use a much smaller hose... I'm no engineer but I wonder if that may explain the difference somehow?

Steel case on aluminum gland. Trying to replace the whole thing but with being on back order who knows when it’ll be in.

***SOLVED! When I tilted back I must have kicked the control patter selector (which is oddly located by your heel when seated) It was maybe five degrees off the CAT control setting. This allowed only the functions that were the same between CAT and SAE to work. So the tilt alarm was unrelated to the issue. Thanks again for all your help.***

Hello all. I'm renting this bobcat e20 and it gave a tilt alarm and locked me out of the controls. I could easily get myself out of this if I could just USE THE CONTROLS. Does anyone know of an override? And is this a safety feature or am I experiencing something else entirely.

PS The User Manual is $60 so I thought I'd ask you good people first. Thanks in advance.

***Forgot to mention: the tracks still work and the cab still rotates (left controller left and right) and the bucket can still go in and out (right controller) but the boom and arm itself is not moving.

This stump weighed in over 1200 lbs, completely water logged. The ground was too soft for the excavator so we adapted and over came.

Curious if someone can point me in the right direction to swap this valve body over from 4 sticks to just 2 not really heavy equipment I realize but figured I would ask here

Anyone use the enego module to do a deleate?
Just ordered one, should be here next week, looking for anyone with first hand knowledge
