    hydraulic bypass power trac pt1850

    Post that in the power trac forum and give Terry a call at PT. Procedures change a little over time. Have your serial number ready. I have an 1850 and will check the manual for a tow valve.

    MH 4800 / 5000 Kohler engine

    Fwiw I converted both of my mh5000 units to Honda gx630 engines and Lovejoy type jaw couplers. The power is ample the reliability much better.

    Yanmar SA424 possible water contamination in Hydraulic Fluid

    The more filters you go through here the better you'll feel about the outcome 😁 You can totally manipulate this cyls manually. They'll take a little grunt and then mooooove. So be aware of its path and pinch hazards... The fluid will kinda blast out of the house at first...You can set up a...

    Hydraulic circuit add

    Thanks for chiming in, always appreciate the input. By the looks of it, the first pump is the transmission, steering & drive. the second is all the cylinder functions, third looks to just be makeup flow. I'm going to tackle this in two parts. 1-diverters on the swing cylinder flow when...

    Hydraulic circuit add

    I've had great experiences with Kubota and yanmar, idk what their sauce is cousin power maybe? Wouldn't work worth my fam 🫢 I appreciate you putting some thought to it. I could power the diverter indefinitely since there's a path back to tank and everything else gets flow... Just a little...

    Yanmar Y9D & Y16 Dozers sold in USA

    Looks like a rice patty tractor repurposed. Man I thought I had all the oddball traction units. Didn't have one of those but use two of the struck magnatracs in trail building. They are stout and place plenty of power in the narrow places I need. I did recently get this yanmar relic in great...

    Yanmar SA424 possible water contamination in Hydraulic Fluid

    👍Good explanation of the situation, that helps a lot here. Water can't leave the system without your help. Probably no serious damage. You'll likely need to work the remaining water through my changing filters and moving all the cylinders power steering etc. Parker makes a filtration unit...

    Hydraulic circuit add

    Thanks for thinking through it and responding . That setup would be simpler for sure, but would leave me with more levers. I'd like these two functions on buttons to replicate standard-ish controls. I guess it also leaves the control valve with no flow (for cylinders) when actuated. I have a...

    Aftermarket diverter vs. factory quick attach control valve?

    I got tired of having my knee in the valve of my 425 so I replaced it with a loader valve w power beyond + a 3 spool valve. Now I have loader on a two spools at an appropriate height; QA, grapple and my 3pt lift cylinder on the three spool. I can use one hand for the loader and grapple. I've...

    Hydraulic circuit add

    Ok, so this is for a small excavator, but my tractor people here know more than most... So please help if you're in the know... Got an ancient great condition yanmar excavator and need to add 2 cylinder functions. I could use solenoid diverters and steal the flow from the little used swing...

    Trying to find the right cylinders

    Happens to all of us eventually bud.🫢 Measurements: Retracted length, retracted pin centers, stroke, bore and rod diameter, 2500-3000 psi will do for a tractor. Given what happened, it's likely less cost to get a slightly beefier matched pair from surplus center, Magister, TSC and fit up new...

    TYM T474 SIDE LINK

    Ideally the retracted length of the cylinder is about the min adjustment of your current side link. My tym built rk55 (t574) uses a 21 inch between pin centers cylinder. So you might want one notch shorter. Can get details if you need.
