I have found there are two varieties of Hard Chrome Hydraulic Rod. One is "Induction Hardened" under the chrome and the other is not. From conversations with a Machinist Morgan Friend of mine, He speculates the "Induction Hardened" rod gives a better base for the thin layer of chrome. My King Pins are of the "non hardened type" as they are from the first batch I made. At 50,000 miles I inspected them and there was some damage to the chrome. I turned them 180 degrees and reinstalled them with the original vesconite bushes. I also did not grease for 2 years and I guess 10,000 miles with out greasing. Seemed OK to Me. I now grease once a year at Spring maintenance time.
I did replace stainless KP's and Devol bushes for a friend in Texas, the pins were badly worn but Devol bushes were OK. I replaced the Devols with Vesconite.
On My +4 I used Devol Bushes and chrome KP's. I have kept this system greased regularly. Seems to be OK. Over 40,000 miles on this rig. (My estimate) One of the attributes of Devol bushes is the "Resultant Fit". The axle tube is reamed and I had it honed. I have a set of Devol bushes in My spares.
Remember I live in Seattle, Washington, USA. The closest Dealer is 1,000 miles from Me. In British Columbia, Washington and Oregon there are about 150 Morgans. Not many of these are Road Worthy nor driven very much.
The use of Vesconite was pioneered by an Australian Mining Engineer. I found a source of this Material and introduced it locally. Vesconite if a South African product used in pumps for mines and the marine industry as well as other uses as a replacement for Bronze bushes.
If I were a Brit I would use Peter Mullberry's products. I am not and find making the pins out of hydraulic rod and bushes out of Vesconite is much less expensive and has done the job very well for Me.
