Hi everyone. have a 48 8N with a Dearborn 19-23 loader on it. The bucket hyd cylinder is history and went to a hydraulic place today and they told me that they can sell me a replacement. There is a 75% cost difference from a max 2500 psi to a max 3000 psi cylinder. I have the Old Vickers type front mount pump number is V250 5 6A 12.
How much PSI does this pump put out? I think I would be safe with a 2500 max psi cylinder, but don"t want to chance it if I cant find out for sure.
 
Pressure is dependent on the relief valve in the system. Most I have messed with are in the 2500PSI range but I have seen them higher. That pump can if you have the relief valve to do so go upwards of 4000PSI. That all said good chance you can use the 2500psi cylinder but unless you check your system with a gauge who know how some one may have adjusted it
 
Thanks "old" Most of what I have read supports what you say. I think I will risk the 2500 cyl and see what happens.
I will let you know if she blows!!!

cheers

What I di is use a simple hyd pressure gauge then you know for sure. I have one in my shop set up wit ha quick connect on it but can also put it in line most any place. Always better to be safe then sorry and with pressures in the 2500psi plus something going wrong can cost you your life

Your system is designed to operate with a working pressure of roughly 2000 PSI and that is governed by the safety relief in the control valve.

As long as the pressure relief on the valve is operating correctly a 2500 PSI cylinder is fine on that loader. The "working pressure rating" on modern hydraulic components includes a safety margin of 2X and the burst pressure is typically close to 4X the rating. I'd be more worried about the iron pipe fittings that were never intended for hydraulic use and have a working pressure of about 300 PSI - not to mention 40 year old hoses.

Before plunking down a bunch of cash for a cylinder at a local hydraulic supply checkout the prices here - new Prince, Lion, Cross, Chief, and house brand cylinders at excellent prices:

Get yourself an inexpensive 3000 and/or 5000 PSI pressure gauge and a 1/4" x 18" hose assembly with JIC 6 swivel ends while you are at it. Perfect for pressure testing hydraulic systems. I prefer the glycerin filled gauges and pay the little bit extra they want for them....
