I’m not a great lover of king pins having had bad experiences with a Messerschmitt KR so best to squirt some grease in there and keep them sweet, good idea.
First the grease gun would not seal and grease went anywhere but down the hole. So a new grease coupler should fix that, now the new coupler fouls the nipple mounting area. So better proportioned nipples should fix that, well grease went in the top nipples (it is a 500R with twin nipples each side) but now the left grease nipple points directly at the brake disc and there is no way to connect without removing the disc or a 45 degree nipple should fix it. Still no way would grease go into the lower nipples. After reading on the forum that just maybe the bushes have been fitted with the grease feed hole misaligned preparations were made to drill through the bush, this should fix it.
The nipples removed but the expected bronze bushes look a funny ‘steel’ colour and with no hint of a grease inlet, so back to the forum and the interweb.
So now I find there are teflon lined bushes that can be fitted as a cheap option to the original type bronze bush so it looks like that’s what I have; so if I may, a couple of questions:
Are the steel/teflon bushes a good idea? do they last OK? and do they need grease and if so how to get it in there. And for academic interest what would be the grease path for original bronze buses with twin grease nipples?
