Power steering
Lotsa opinions and comments..........proves there's more than one way to skin a cat, eh? I've wheeled two different 55's, started with my 71 with manual steering. Wheeled it two years without breaking a thumb. Sold it with manual steering (but added disk brakes, another story there).
Bought my 78 and wheeled it one year without power steering. Too much work and actually dangerous unless you're really careful. I decided to go the easy route with power steering, and bought a mini truck box bracket from lance. The bracket not only looked good, but fit perfectly. No welding, no cutting, drill the rivets out of the existing bracket and bolt on the new one. For a pump I use a mini truck (any 22R engine can be a donor) pump and had Jim C modify the bracket and add a pulley so that the pump mounts right to the original smog pump bracket. It is tucked away very nicely at the bottom of the engine and uses the original 17MM cross section belt that Toyota used for the smog pump. I mounted the reservoir high on the inner fender.
That setup worked great with 31" tires. i then went to 33 x 9.50 tires and the PS setup still performed very well. Never had a problem with it and can recommend it to anyone.
When we did the spring over and of course went with high steer arms it was an opportunity ( a must, actually) to get rid of the original steering arms and center steering pivot bracket. I liked the way Mark Whatley described his FJ60 steering box installation and we went that same way. Welded a piece of 3/4" plate directly to the frame rail, it has four drilled and tapped holes for M12 bolts and not only looks strong, it IS strong. I kept the mini power steering pump, too. My truck runs 35 x 12.50 mnud tires and this power steering system works perfectly. It's great on the trail and perfect on the road. My pig runs down the highway straight as an arrow and I think the effort required to turn the steering wheel either on or off the road is perfect.
I'm a big fan of keeping Toyota parts on my trucks. Nothing wrong with a Chevy engine or a saginaw power steering box, just my personal preference. I have to say that I believe the mini truck pump's output is adequate for any Toyota application I've yet seen. I've seen some good saginaw pump installations and some that were hirrible. I've seen some Sag power steering box conversions that were well done (John Merkey's work comes to mind) and some that were downright scary. Using a 60/62 box requires no frame siderail or crossmember cutting. If that ain't a good thing call em stupid....... My mini truck pump hasn't neede a belt adjustment since I installed it three years ago. It's a great install and I can't imagine anything better. No squealing belts, no throwing belts, no misalignment.
A few points of interest here......while the 60 and 62 steering boxes have the same basic configuartion they do differ in a few details. Either box is a great andidate to install on either a 40, 45, or 55. And pulleys........I can get the correct 17MM pulleys here at work, I buy them from a vendor with whom we do over a million dollars of business a year. I get a tremendous price on the parts and will get pulleys for anyone who needs one. These have a tapered center and use a taper-lok hub to secure them to the shaft of either a Saginaw pump (3/4" diameter) or a Toyota pump (I think 18MM diameter). I think a pulley and hub are less than $40 for the pair. These things work great and are an easy install.
Anyway, that's my two cents. I'm not a hard core wheeler, don't need a hydraulic ram to steer my piggie, but do know what worked and works for me, and can appreciate the fine points of a good installation. By the way Whatley's article appeared in the July/August 2003 issue of Toyota Trails and is an outstanding source of information. HTH.....Gary S
