Char-Lynn power steering on a 88

super99 · Mar 28, 2014

Does anyone have a 77 or 88 with add on power steering? I have a Row Crop 88 with a 77 motor in it with a Char-Lynn power steering unit on it. It is plumbed to get oil from the hydraulic unit on the tractor, I would like to add a separate pump for the power steering ( bought a used pump on e-bay for $20.50 plus shipping). If anyone has one, I would like some pictures of how it's mounted and the belt drive. Do I need a double pulley for the water pump, or can 1 belt drive the pump and the generator? Does a double pulley throw the large belt that drives the water pump out of alignment? Is the pump mounted on the same side as the generator. Looks like the air cleaner is in the way on the other side. It works like it is, but the steering is slow, it turns easy enough, but you can't really spin the wheel on a tight turn. Any thought or comments welcome. Thanks, Chris

Chris: Back in the day when we were installing the Char-lynn kits out of the box a second pulley that bolted to the crankshaft pulley was included. The bracket that supports the pump bolts on the thermostat housing. It is a 2 piece bracket. There were two styles of mounts for the power steering pump reservoir. One attached to the valve cover. We have an 88 at my employers right now that has a Char-Lynn on it. I would need to look at the details on how it is set up. John

I have an 88 with a Char-Lynn kit that I bought and installed myself back in 1974. The fleetline 88 uses a special spacer between the crankshaft pulley and the add-on pulley that was not used on Supers and newer. Had to make one myself, because it wasn't available for some reason from Central Tractor at the time. Or I didn't want to wait for it. Or I was too cheap.

Chris I put a new Char-Lynn unit on a 880 I owned and farmed with in the early 70's. Can't remember exactly how the pullys worked, just remember cutting the steering shaft and that as you said, didn't turn too fast.

Chris, I helped my dad put put a Char-Lynn PS unit on my 770 Oliver right after he bought it new in about 1962 or so. A pully supplied in the kit was added to the crankshaft to run the PS pump. The PS pump is mounted on the thermostat housing. The PS belt only runs the PS pump. I can send you a close-up picture in a few days as the one I included doesn't show the details. Let me know if you want a close-up. Al

I have a 77 and an 88 with charlynns, both drive off a separate pulley. the pump sits up pretty high under the hood and is hard to check fluid levels, the pulley also can rub against the side curtain. If I was starting from scratch I would try to mount it more where the generator is and move the generator up. they work great thou.

I put a chevy pump on my 88, I used a S88 thermostat housing on the head with the rubber hose and made the bracket to bolt to the housing bolts, I put an extra pulley behind he water pump pulley to drive it, it worked ok and made a loader on an 88 tolerable.
