Hmm, I wonder if Bill has any pics of it in his gallery. I always thought I would build one like that w/ maybe an 8000watt gen. from Northern. Seemed like a great application for a 332. Bill sent me pics of it a few yrs ago, but I don't know where they might be.
I had saved four pictures from Bill for future reference. I now have use for them and wanted Bill to confirm what diameter pulley he used on the generator head. Looks smaller, probably a 5.75" as the PTO pulley is 6.5" (at least on my 318).
Michel, I will need to check on the pulley diameter, but I think it is 5.5". Both the big one-lung kohler on the 314 and the diesel on my 332 are not happy operating at 3600rpm, so I needed to overdrive the generator a bit. I didn't want to overdrive it too much as I thought a closer to 1:1 ratio will provide better voltage & frequency control. I'll check for more pictures.
You mean you ran water and didn't figure on having to live back there??
Oh that's right, you keep referring to the significant other as 'girlfriend' and not as 'wife'. Us guys w/ wives figure the outbuilding better have heat, AC, telephone, cable, water, AND a bathroom 'cause sooner or later we're gonna hear something like: 'You and those tractors, you spend more time w/ them then me-why don't you just go LIVE W/ THEM'.
And that way, we'll be comfortable when that day comes.
I have a 455 with a 40 loader and the special forward drive relief valve. I think it is relieving too quickly. With a small blade on the back, the tractor will stop moving before spinning the wheels and/or bogging the engine at all. Also, I have some really steep places on my property that will cause the tractor to stop when climbing. again, with no wheel spin or engine slow down.
In reverse when backdragging with the loader it has much more pulling power.
My manual is packed away at the moment. so, my question is this: (finally!)
Where does one tap into the hydro to measure the forward drive pressure?
It looks like the optional loader valve can be adjusted with shims, like the charge pump relief. but, I'd really like not to do that without being able to see what I've done!
Ken, I have no issues with mine, but I think you have correctly diagnosed your valve as opening too early. I wonder if a good hydraulic shop could test it for you? I'd imagine it's pretty expensive to replace on a trial basis.
The AM121248 pressure relief valve is set by JD to 3,199 PSI. The relief valve pressure can be adjusted by adding shims like the implement relief valve. The problem there is no information shown for the shims. I would guess that shims for the implement relief valve might work. SInce there is no test port, you would be just guessing what the resulting pressure would be.
Thanks for the info. I think I'll contact a dealer shop on Monday and see if they have a setup to shim and test. I would remove the valve and take it in for the work. There doesn't appear to be any access to test the pressure on the tractor.
I am repairing a 455 hydro and spent a lot of time attempting to find a way to test the hydro pump pressure. First, the hydraulic pump to the hydraulic motor is a closed loop system. Second, if you COULD test the pressure, you would have to stop the hydraulic motor from turning and then have the engine WOT and press the forward pedal. Just locking the parking brake could damage the brake or the internal components of the hydro.
I believe the internal pressure of the closed loop hydro system is 1550 PSI so the factory setting of 3200 PSI sounds about right. Since the valve seems to be working at a much lower pressure, leads me to believe the relief valve was never set by the factory. I would disassemble the valve and see what shims are present. Adding a shim would be simple and then you would just have to try the tractor to see if it fixed the problem.
No, I just haven't had time to play with it. The dealer did not have a way to test it off the tractor and doing it by trial and error will take more time than I've had available 'cause I would have to pull the fender deck, try a small shim, reinstall the fender deck, try it out. and repeat. Then I still couldn't tell if it was OK or over pressure! Maybe later in the spring.
