Your latest truck project... - 02/15/04 11:36 AM
My last major project was 'encouraging out' the old king pins. Someone here or elsewhere suggested using the weight of the vehicle and a generous soaking w/ PB Blaster to achieve success. In my case it worked like a charm.
The truck is lifted and properly supported while you remove the backing plate and coat-hanger it off to the side. I then created a stable vertical support for my brass drift by drilling a common hole into a stack of 10"X10", 2X12 board scraps then securing the stack together with 3 " wood screws. This created a stable vertical support for my 6" brass drift. Upon removal of the king pin end caps I then lowered the king pin onto my home-made brass drift assembly.
The goal is just to get the stubborn king pin started so only 1-2" of drop is allowed before 2 jack stands await the front I beam for safety. I would come around and give a dozen good blows to the outside of the vertical king pin assembly with a five lb. sledge and a squirt of PB then go back to listening to Public Broadcasting Saturday AM and then come back after another half hour or so. Once I noticed a 1-2 mm drop all thoughts of jerking the whole axle and taking it someplace to have the K-pin pressed out melted away.
As with most things in life and with our old trucks, good patience is rewarded in the end with success. Let's hear your latest truck project, large or small...regards, Cosmo.
