Re-installing King Pins on BJ8

Well, once again "nothing is going right" in my little king pin replacement project. You may recall that I previously asked for advice in how to remove the tapered pin that positions the threaded lower trunnion pin/bushing on the lower trunnion. Well, your advice to "lubricate and hammer it every day until it comes out" worked. Lots of hammering. NOW, the same pin is causing me problems during the reinstall. When I replace the tapered pin not enough threads show to tighten it up - despite some hammering on it. It seems to me that the tapered pins I bought are a bit too thick ???? Is there a trick to doing this properly? I have checked to make sure that the indented portion of the threaded trunnion is indeed where it should be, but I have tried twice to get the thing installed to no avail. I will have to purchase a couple more of the tapered pins so have a few days to ponder. Very frustrating little project. No wonder I put it off for so long! Thanks in advance for any advice!
 
The flat on the fulcrum pin must be exactly parallel to the flat on the tapered pin. If it still won't go, file a bit off the flat side of the tapered pin until it starts well. Not much fear of it ending up too loose to do it's job.

Hi, Dave,
I will be ordering a few more of the pins today and if they don't do the job OK I will file some off. I had considered doing that yesterday, but had already buggered up the threads pretty good getting them out after attempting to get them in. They appeared to be the same dimensionally as the ones that came out of the car but the tolerances are evidently quite tight. I appreciate your help - as usual!
 
Just a thought

You are not mixing up one of the cotter pins on the two arms with the one fixing the lower trunnion pin, from memory they were different sizes ( I think)

I do not recall having that trouble, I bought mine as a complete kit of parts.

Put the pins in the freezer overnight. Works great for wheel bearings too, especially if you put the housings in the oven!
 
I think that the domestic godess would have something to say about that in our kitchen

GOOD POINT THOUGH

Boiling water in another good warm you up for those bits that can not be lugged into the kitchen
