I have some more questions....

Is it better to tap into the existing hydraulics to feed the new steering pump, or better to use a separate reservoir and filter ?

If I keep the systems separate, is a spin on style filter (see below) in the return line to the reservoir a good choice, or is there something better ?

If I buy or make a separate reservoir, is bigger better ? My thinking is that a greater volume of oil and larger reservoir surface area will help with cooling.

Many thanks.

You have 4 gallons in the sump and a 4 GPM pump on the tractor. Significant head room there. What size PS pump are you contemplating? i would think pretty smsll.

A suction side screen and return side filter would be optimal and an improvenent over OEM.

Thanks Dan.

When I get to the shed today I'll see if I can work out where to tap in for supply and return lines.

The pump I've bought is 4.9 ml/rev. So 12.2 l/min, 3.2 GPM at 2500 rpm. That gives me 1.9 GPM at 1500 rpm - the tractor isn't much use below that.

Are you saying that the filter I've pictured above would be suitable for the return side ?

Suction side screen - is that something that would be fitted into the suction line to the new pump ?

Today I made the bits to mount the double-ended steering cylinder.

Due to the larger diameter front tyres I fitted a while ago, space is pretty tight. The current long drag link only just fits....

....so fitting the steering cylinder, whether it's the one I'm using or if I was using the more standard type, will take some care.

Here's the new assembly somewhere near where it will end up.
