BX25 Mid PTO Pump or BUST

[J_J]

I have used both PTO rpm before, and have used the 540 position when using the MMM. I never did pay attention to the rpm. I assumed it was running at the rpm it was supposed to.

Apparently there is a set of gears in there when using 748 rpm on the rear PTO, it makes the Mid PTO run at 2557 rpm, and when using 540 PTO, the MMM turns at 1847.

The B8200 has three PTO's rear, mid, and front.

The rear and mid have two speeds, and the front only one.

Theres and idea! But I think I will live w/ my Spartan 2001 loaded w/

J_J I am grasping in thin air here trying to understand your 2-Speeds PTO
deal.


What is it, at idle then at wide open or is there a PTO Tranny w/ a gear selector?

 

[J_J]

Yes, there is a gear selector. If you select the 540 rear PTO, then the mid turns at 1847 rpm, and when you select the high rear PTO of 748 rpm, the mid turns at 2557 rpm .

A little more versatility I suppose.

I see, said the blind man, as he picked up his hammer, and saw....

Gents in drawing a tank and in doing research I am running into 2 schools
of thought regarding the filtering. I drew in an in tank strainer, 2" w/ I
believe it was a 1.25" outlet and then I saw a a couple of guys say NO.
They suggest to eliminate the debris at the FILLER NECK instead of inside
the tank, as in stop the debris at the inlet, before it has chance to violate
your system, where you can see it and remove it.

I will have an inline paper filter between the tank and the pump inlet down
to 10 Microns as well.

So, I propose a strainer 40 x 40 on the filler neck then a 10 micron as well.

good, bad, ugly?

I am of the opinion that if you have a filler neck strainer, a return filter and possibly a pump inlet strainer you will be fine. I dont like filters on the pump inlet. Too much chance for them to get plugged and starve your pump.

You want to keep a hydrostatic transmission as clean as possible, so a good many of the systems have suction filters before the charge pump.

Our Power-Tracs, have been using the suction filters for over 25 years, and I don't know of a failed hydro transmission due to a clogged suction filter.

Sure the potential is there, but how likely is it, unless the tank fluid is really nasty. If the hyd system fails because of a clogged input filter, then the system already was having trouble.

A filter monitor with a gage or a no/go indicator should be sufficient, or even a warning horn.

You could do all three, suction, return, tank filter.

i agree with jj on this we always used suction strainers and even some that incorporate magnets

I didn't know you can fit 137' of magnum cable in a 2001?

My go to is a Spartan 300 with magnum cable.
