Max pressure, yes. Flow is rpm dependent if the lines are sized appropriately. Small positive displacement hydraulic pumps are generally rated in cubic centimeters per revolution, so more revolutions per minute = more cc per minute.

The OP did say he had a second pump that was originally installed to supply a backhoe. The flow rate may not be too bad.

I have as 3ph mounted backhoe. I know the difference between a frame-mounted BH and a 3PH mounted BH. I transport it by stowing the boom, dipper and bucket, raising the stabilizers, raising the FEL bucket and driving away. Yes, one of the features of a 3PH is the ability to lift and lower...

The picture you posted shows what I am talking about. That BH can never be lifted by the 3PH. The top bar (Kubota calls that a "mast") goes to the immovable upper mounting point of the 3PH on the tractor. It is braced to the normally movable lower links of the tractor's 3PH. Because of the...

Not that it is relevant now -- the backhoe is long gone, the tractor is not orange -- but I am having difficulty understanding how the lifting capacity of the 3ph was a factor? Or was it just that the weight itself made the unit too light on the front end? I am far from expert, but any 3ph...

Ok, sounds like you are on it. Isolation valves are, ummm, non-standard in an OC system, usually they are configured with a Power Beyond port, but so long as you know the limitations (and hopefully have a relief valve before the isolation valves, just in case...) it can work. What got me...

Is the tractor an open center or closed center system? It was hard to tell how many hoses were in that tangle. Tees should not be used with open center systems. Impliments are connected in parallel with closed center hydraulics, but in series with open center systems. JD uses closed, Kubota...

My dealer has never given me the cardboard box -- he substitutes a blow-molded chainsaw carrying case. I'm good with that.

I hesitate to jump in here due to the liklihood of getting flamed by the OEM purists, but the harsh reality of life is that you may have no choice but AM. I ran into this with some older saws like my 084. Stihl just doesn't offer the cylinder for every saw they ever made anymore. Yes, you...

Back to the original question: Briggs owed $800 million and went bankrupt. They've been bought and reorganized. Maybe the cans were one of the casualties? Especially if the company making the cans for Briggs was one of the creditors? Ironically, that's how Briggs acquired Murray.

Since we're digging up old stuff: Reverse rotation engines are actually quite common in the marine world. Usually paired with a regular rotation motor in twin engine setups so the props spin in opposite directions to cancel torque lift and prop walk. Reversing the direction requires a...

I had a Gravely, with the optional dual wheels with Ag style tires and the optional low range gearing. I had a home-built yard trailer/sulky. It worked great with the rotary mower or sickle bar attachments. Not so much with the rotary plow or snowblower attachments. There were no brakes (maybe...

The easiest way is to take them in and have them sharpened by a service. Not the cheapest, perhaps, but if you are either a homeowner who needs a few sharpened each year OR a business paying skilled labour rates for a climber/faller to sharpen chains, it might be cheaper in the long run.

There are some people who object to insurance on religious grounds; they see it as a form of gambling. They are not wrong. Just like any bookie or Vegas casino, the house is calculating the odds, planning on paying out a certain percentage of the take, but planning to make money overall and...

Crude petroleum may not have come from dead dinosaurs, but it is fossil based -- it comes from the bodies of dead plankton. Dead vegetation produces mainly natural gas. And while technically it is self-renewing the reality is the process takes an estimated minimum of 10 million years up to 60...

Apparently Stihl dealers will check saws coming in for repairs against a serial number list of stolen saws. Mine does, anyway. Not sure how they handle it if the serial number is ground off though.

What link? I can't seem to find it.

Ummm, I can see that it is rated for TC-W3. Everything else I see are just claims, not ratings. This thread reminds me of all the lawsuits over 303 tractor hydraulic oil. Sold cheap with unsubstantiated claims that it was "suitable for all tractors", when in fact the former Deere spec was based...

This article from Spectro is a little bit dated, and oriented towards snowmobiles rather than chainsaws. But there are some parallels between the two and it does highlight the engineering process that goes into 2-stroke oil specs:

The professional engineer at the manufacturer shared all the specific information about which oil you need with you in the Owner's Manual. Look for a phrase like "Use API-TC specification", (or JASO-FD, etc.). Then all you need to do when you go oil shopping is make sure those letters follow the...
