My car had not driven in the 20 years before I got it, so I decided to go thru the steering box. It is a std 19:1 box, but I am adding quick turn pitman and idler arms to improve performance. Anyone have this combo? Wondering how it will be, as the quick turns are usually used on 16:1 boxes I think…
Box as removed (broken, seized up bolt and all):
Pull off Pitman arm w/ Autozone rental puller:
Remove cover plate and sector gear:
Sector Gear:
Remove the big sheetmetal locking nut and remove shaft and ball nut:
Address the broken bolt, center punch, drill... got lucky, was almost up to the tap drill size when it grabbed and turned the remaining threads of the broken bolt out:
Everything looked good, so I decided to just clean out all the grease, replace the seal and re-assemble and adjust:
Reinstall the shaft, supposed to tighten to pre-load the bearings and produce a shaft running torque of 4-5 in-lbs after the lock nut is tight:
Check the sector shaft shim clearance, should be .002�:
Put the sector gear back in with the adjusting screw, gasket and cover in place. Adjust the screw until the steering shaft running torque increases to 9-10 in-lbs at the center of its motion. These boxes are designed to drag at the center to ride better on the highway.
Pump it full O’ grease, paint, and a quick turn pitman arm and it hopefully ready for another 45 years of operation…
