Talk Morgan Forums Thread Like Summary - king pin bushes

In the process of servicing my Plus 4 Ive detected a small amount of play in the nearside king pin. So while the weathers still poor I'll have a go at replacing them. Lsat did this a good few years ago on my previous Plus 8 so I know the procedure (although I'll have to cadge a reamer from somewhere!). I want to make a drift for the bushes but don't know the external bush diameter, I assume the inside diameter of the bush is 1 inch but does annoying know the outside diameter?

thanks in advance

Physics and metallurgy......

Quite simply, you are forcing a soft hollow round piece of metal into a harder round piece of metal as you don't want the smaller piece of metal to fall out.

The smaller piece of metal being ever so slightly larger than the hole in which it has to fit.

Which causes the sidewalls of the bush to distort and the kingpin not to fit the bushes, hence the need to ream them so the distortion is removed and the king pin fits the bushes once again.....

Brill thanks.

I’ll get the parts ordered from Wolf today but for those of us ‘Oop Norf’ a day trip isn’t feasible hence the DIY approach. Besides I enjoy the satisfaction of doing the job myself.

Cheers

I had Cain at Wolf Performance supply Mulfab hard chrome kingpins, renew and ream bushes etc. Having pre-booked with him it was a while you wait process when I brought the stub axles over, but admit I only live 52 miles away.

Cain at Wolf will replace and ream bushes while you wait if that mitigates the travel distance. He uses Mulfab kingpins and bushes.
