My friend has a 1953 77 narrow front with a loader/snow blade on front. Getting hard to steer for him. Anyone heard of ps on a 77 or possibly an aftermarket kit??? Thanks in advance!

My brother has a Charr-Lynn power stearing set up on his "77" , which also has a loader on it. Seams to work good.

I used a Char-Lynn unit on my '52 77 Industrial. See link for photo. The parts are available new at the Surplus Center.

CharLynn made a power steering add on unit works good. expect to pay around 400 used for one. The ones for 250 to 350 are always sold before I find them. The ones for 400 only last a week or two.

Hi there evielboweviel,

The Char-Lynn torque generator (called steering valve) is item #9-1848 for $399.50 + shipping. The priority valve (w/relief) is item #9-4158 for $78.95 + shipping. These are 2002 prices. The hydraulic hose and fittings, etc. are available at local hydraulic supply companies...also NAPA. You have to custom fabricate some kind of bracket to mount the torque generator and to keep it from turning. I used 1/4" steel plate. You'll also need a couple of universal joints to install in the existing steering shafting, together with a new, longer section of shafting from the steering box to the torque generator. These are available at any local power transmission supplier. As I recall, I paid about $50 for the U-joints and about #20 for the keyed shafting. All in all, figure on about $650 if you do the labor yourself.

The numbers for the generator and priority valve are from Surplus Center, Lincoln, NE. I don't believe they have a web site. Call them at 1-800-488-3407 and request a catalog...lots of good stuff :o).

A word of caution: The torque generator takes about 3 gpm to work. The priority valve supplies this BUT it is robbed continuously from your main hydraulic supply. You need to have plenty of supply to begin with. My main hydraulic pump is about 20 gpm so I am now reduced to about 17 gpm to run other equipment. My loader is noticeably slower but I consider the ease of the power steering to be worth it. If you don't have a main system that you are willing to take 3 gpm away from permanently, you will need to find a solution other than the priority valve. Or repace your main pump with something bigger. The quick fix is an old power steering pump and reservoir from a car or truck dedicated for the power steering...but you need to find a place to mount it and drive it. The torque generator is rated at 1000 psig, although I run mine at the 1500 max psig preset relief of the priority valve without problems. My main system runs around 1200 psig.

I also posted this back at the thread I linked to and where you requested it.

Rod

I just got a char-lynn unit in on a super 77 diesel that isn't running ....yet...but is this unit suppose to not work unless tractor is running? We have no steering action when turning wheel.

If you are talking about the Char-Lynn Torque Generator mentioned in my above posts, it should steer without the engine running or without hydraulic power to the unit...there is just no power assist and it would steer hard, but it should still steer.

My recollection of an old post is that steering does not work unless pressurized oil is being supplied (ie, tractor must be running). That is supposedly why Char-lynn quit offering them- guys were putting them on old cars, with resulting disasters if engine quit at 60 MPH and you're suddenly unable to steer. Not a big problem with tractors, but lots of liability with cars.

I think you have discovered a law of nature- depending on the season, its either a blizzard, a deluge, or 105 in the shade whenever you have to winch-load something onto a trailer.
