Do you have the style with a collar that pulls back to retract some balls? You may need to clean or lube things. I prefer the style with the simple spring loaded pin on one side.

I change it every spring before putting it away and check it again in the fall when setting it back up. More because I want to avoid any moisture issues than any leakage of lubricant -- that would be readily apparent. There's not too many places the gear lube can go and the box is right there...

The carbide used for milling wood is a different grade than the carbide used for milling steel. Wood bits are typically C2 to C4 (softer, tougher and less likely to chip in an interrupted cut) whereas steel milling bits are usually C6 or higher (harder, more brittle, holds edge longer in an...

I wouldn't go more than 65° for sure, especially with mild steel. IIRC, I think I settled on something closer to 45°. But mine is also home-grown and I didn't experiment with various angles to really say what is the best. Whatever I settled on depended heavily on what angle was achievable given...

Oh, so to actually answer your question: No. To lift more weight you need to increase the pressure or increase the cylinder diameter (ie: larger surface area for pressure to push against). Increasing the cylinder diameter will also increase the volume required to fill that cylinder, so it will...

Don't confuse pressure with flow. Flow rate determines how fast a cylinder will move, pressure determines how much force a cylinder can exert. Volume of the pump determines flow rate, force of the engine determines maximum pressure (up to the relief valve setting of course). Let us assume a...

What he said. I would add: use chain-specific lubricant on any drive-chain. And after many years of use, you may need to replace the shoes or cutting edge. Depending on how much road salt the blower has seen some scraping and painting may be warranted. And if you deal with wet snow, an...

Ooops. Double post. Deleted.

I'm having a real hard time buying this one. Evapourating alcohol out of water is called "distillation" and requires a temperature of around 80°C or a Mongolian still or the addition of a high concentration of non-iodized salt. The distillate (alcohol) must be removed immediately because the two...

Yup. Yup. Just going to lift the front of the tractor off the ground. Typically your downforce is inherently less than your lift anyway. The piston area is reduced by the rod diameter when retracting the cylinder.

Yeah that's the device. And no, I don't think downpressure is really so much of an issue with the typical FEL build. But that's how they come. (Unless there's another style were one relief valve is replaced with a check valve. Dan?)

It goes between the control valve and the cylinder on both lines. IE: UP line from control to cross-over relief valve inlet port 1; outlet port 1 to cylinder UP. Same with Down -- from control to cross-over inlet port 2, outlet port 2 to cylinder down. It actually contains 2 relief valves...

Maybe it's seized? <lol>

It's a fantastic build -- very professional. But if he tried to make them for a living he'd have to compete with all the internet forums complaining nice cabs cost too much. $1,200 materials + 120 hours x (say) $40/hr = $6,000 right there with no provision for overhead (like heating the shop...

Over what? Seconds, minutes, hours or days? They all drift down right from the factory, it's only a question of how fast they drift down. For comparison, my B7100 with similar hours will take about 2 days for the 3ph to fully drop a 400lb snowblower from max lift to the ground.

Leave the tractor relief setting as stock. Yes,, some of Kubota's loaders could be had with an optional PTO pump, depending on the tractor they were being fitted to, which may explain the manual's numbers. But as you have discovered, adjusting your FEL relief lower will reduce 3PH capacity...

Yes, some of it looks very familiar! <lol> The design has served me well over the years and I'm glad to see it is of use to someone else. I would echo Wolfman's comments and replace the top bar with round though. Even heavy-wall pipe would bear against the round retainers better than square...

I'm thinking something like a stripped spline or gear is more likely than a bad bearing. But one way or the other, things have got to come apart.

The way you have it is not "wrong" per se, just not ideal. Your clamp strap is sloping downward towards the work piece (sloping upward would be wrong). But if you look at the engagement of the heel steps to the block, they are not fully seated -- they can't be, they are on an arc, probably only...

I was so busy being a smart-ass, I forgot to answer your question: I have two of the S191 sets. I've never used the v-base or the wedge base. I do upon occasion find a need for both sets at once when trying to support an irregularly shaped item and I have very rarely needed the point screw. I...
