Ok so i mounted my 2wd box and it spins the wrong way. if i turn the wheel left it turns the pitman arm right. Am i doing something completly wrong or can someone tell me whats going on? Thanks
 
I thought that all the GM box's (81-91 2 and 4 wheel drive) spun the same direction, Am i wrong?

There are some boxes from vans that look identical but rotate the opposite direction.

As was said before is your pitman arm pointing forward or backwards? It should be pointing towards the rear of the truck.
 
Ya i thought about that but i figured once i got used to it, it would be incredibly hard to drive any other vehicle. but it would be pretty funny
 
As long as both boxes are variable rate or constant rate then the sector shaft should slide right into place no problem and it's easy.
 
damn i think i must have one of those box's. how easy is it to put the shaft into a 4wd box?

To put the 2WD sector shaft into a 4WD box:

Make sure the steering is straight and remove the pitman arm. Remove the 4 bolts on the top cover (don't mess with the adjuster in the middle of the cover). Pull up on the cover and the sector shaft and cover should come out together. That's it!
 
There is a snap ring at the bottom of the shaft you gotta remove before it'll slide out. If you'd like to freshen it up a tad you can buy a "pitman shaft kit". That'll get you all new rubber for that shaft and it's only like 6-7 bucks from Napa.

You do not need to pull the snap ring to pull the shaft. All the snap ring does is hold the lower seal and bearing in place.
 
Thanks Guys i got it all figured out except the 2 4WD boxes i had were variable and the 2WD box was constant, so i ended up pulling the shaft out of another project i've got goin and it fit in one of the 4WD boxes but then that box was the flange type fittings and not the O-ring type so after some hose fitting swaps i got it all bolted up.
 
You guys are right. :bow: I was messed up on my thinkin- not unusual. I was thinking back to when I changed internal seals etc in mine. but yea, that snap ring snaps into the box housing- not around the shaft itself. It's been a couple months since I've been in one, two, three or four of them.

BTW- the part numbers for internal seals I used are

Pitman shaft kit complete 7-180
and
Input kit 7-205 the kit for the throught of the box.- It does not come with ALL of the O rings that I was expecting it to.
 
Variable ratio gear. Look at the Vs in the teeth. The one in the middle is deeper then the 2 on either side of it.

Notice the teeth difference between these shafts. The one on the left is constant rate and the right one is variable.

ya the constant has three teeth that are all identical and the variable has a bigger middle one with 2 smaller ones on each side.. well i went to pull it out of the driveway and the pressure hose blew up :doah: .
