1862 hydraulic pressure vs. 1811

[wally67]

I am in the process of acquiring parts and info to put power steering on my 1811 I have the steering cylinder, front axle and steering valve out of an 1862 but am unsure of the hydraulic pump charge pressure and lift pressure of the 1862 and could not find a manual online to give me this specification. Has any one ever done this swap? Does adding power steering to a hydraulic system require more pressrue to run it? The 82 series manual listed in the manuals section here shows the 782 having a lift pressure of 500 psi to 625 psi and the 982 having lift pressure of 700 psi to 900 psi but the 982 does not have power steering. Is the extra lift pressure do to the heavier implements it uses? Thanks for any help or insight on this, Wally

It will work fine...the 1811 and 1862 have essentially the same hydro unit.

Thanks Matt, Will the 1862 hydro unit bolt to the 1811 rear axle or an older cast iron rear axle out of a 149/1450? My goal some day is to do like you did on your super and put a cast iron rear end in this with fine spline axles.

It would, but you would have to use a CV joint driveshaft from the 1862 as well, because the input shaft on the 1862 pump is splined.

Great, Thanks for the info now all I need to figure out is how to adapt the steering valve to the non tilt dash the 1811 has

I used a 300 series Deere power steering unit when I converted my 782 to power steering and it was a relative simple swap.
It lowered the steering wheel about 1" but other than that it worked fine, without changing the shims in the pressure relief valve in the hydro.
