Refitting trunnion and .008" Spacers

Those 4A Washers can indeed fit under the trunnion to raise it. I tried 1 .008" shim there as well, made no difference.

You may need to add more shims. You will be actually tightening the trunnion against these shims and the shoulder on the kingpin. You should be able to tighten up the castle and have vertical play in the swivel. then remove shims until vertical play is reduced.

Who ever said torque the castle nut. I always take em down till it will not turn then back off enough to get the key in. That us usually just right. Give it a try.

New Castle Pins are replaced by a nylock and kingpins are not drilled. I may need to give my new Cross Slide Machinists Vise something to work on and drill the top of the kingpin to accept a cotter pin.

By all means drill the kingpin, but, I actually just did the same with the nylock, so far so good

WAIT A MINUTE!

Jim, here's the order of things.....
From bottom up.
Kingpin in vise
Round crossection o-ring in the groove between the lower kingpin bushing and the spindle housing
place spindle on the kingpin (assuming the dust tubes are in place)
place 2 or 3 shims on the shoulder of the kingpin that's now exposed above the spindle top.
Grease the bronze thrust washer a little (it is oilite, but a little dab'll do ya)
Insert the bronze thrust washer into the trunion.
Invert the trunion onto the kingpin stud.
Push it down.
Tighten the castle nut
The spindle should turn. (NOT the trunion)
If the spindle does not turn, undo catlenut, lift trunion, add another shim. Repeat until the spindle does turn.
If it does turn, be sure there is no discernible up and down movement. Remove shims to tighten.
There are 3 thicknesses of shim. They are meant to fit on the uppermost shoulder (step)of the kingpin. They also fit inside the step in the trunion. If things feel loose, the old shims may still be in there. They do get stuck. They may also still be lurking on the old king pins. If you need more shims, I carry them

Thanks Peter, I will indeed call you if I get stuck some more. Have not had time to look at this again and I wish I had sent you the shims and the big top washer along with trunnions so you could have fitted and tested endfloat. One of those things we learn when you repeat the process more than once every 10 years. As I look at it I may have one of the one big bronze washers under the trunnion already so I don't need to add a second. I'll puzzle it out. If not I'll give you a call.

LOL.... 2 bronze thrust washers!! That'll do it! King pin's barely long enough.

Sit down, deep breath. You'll get it.

Biggest problem is finding time to look at it. Working V.O today so maybe late this PM I can find time for Bugsy if I get caught up on the real job.
