As I had some spare time today I thought I'd finally get around to doing some work on them.
Made a few discoveries..
Stripped the wheels off to discover that the ACS 430 hangers have fully threaded axles, interesting, maybe it was a way of using up old stock of unsold hangers.
Might come in handy for another project that I'll probably never finish.
Cleaned them up abit with some engine degreaser and a toothbrush, came up looking good, the quality of the casting leaves something to be desired though, never noticed back in the day, maybe they were this bad but I'm now more conscious of such things.
I then wondered why I was bothering to clean them up if I wasn't going to use the hangers but did all four anyway.
The bushings were actually in good shape and seemed usable after a wash in soapy water.
The front two pivot cups had turned waxy and disintegrated, have replaced them with some I had.
Found a couple of 651 hangers that I have and offered them up, the kingpins stick out far too much, same as on the 430's, after tapping a rear kingpin out I then discovered that my GrindKing kingpins were too short, the baseplate on the rear is very thick. I then also discovered that reversing the kingpin doesn't really make a lot of difference in the height. A real danger of hanging up with these, the older longer GK KP's might be alright, have some somewhere but probably fitted to some trucks.
Bearing are soaking in degreaser for now but will probably be replaced anyway.
