I am currantly rebuilding front end of my 1962+4, 4 seater. I have carefully reamed my bushings to about 1/1000th play. My question is  how about scoring each bushing lengthwise to allow better passage of grease  the length of the bushing.  I would assume that one cut would suffice. I have seen this kind of cut on racing cars
.
Also my plan is to not use the oiler in the future.  I would think a moly 77  would be the best for slidng action, that is,moly lube with 77% graphite.
Your thoughts please.

Alan,

Morgan has just introduced a new system for the front end with nylon bushes which does not require the oiler, but does require machining the stub axles to accept the bushings. A conversion should be possible, alhough we don't have details as yet.

Otherwise, mol-slip will work as a lube for the front end, as you indicated in your message.

Best, Bill

In response:  As your bushes have already been fitted and now reamed out, you can do no more. An alternative prior to fitting bushes would be to have machined three grooves on the inside, with a "lead in" vertical groove to allow the passage of grease. You can still do away with the one shot oiler and fit grease nipples to the top
.
Best wishes, Melvyn R.

Dear Crazy Horse,

I have always used the standard factory Kingpins and bushings with a .005 reamed clearance. I then pack white moly in between the upper and lower bushings then coat the kingpin with same and insert. At that
point it is done and I am good for 90 to 100,000 miles. This has worked for me over and over. I also cut one and one half coils off of the rebound spring as to give movement to the king pin movement as the rebound spring at full lenght is coil bound and is usually taken out in pieces upon replacement of kingpins and bushings. The factory is at present useing a composite material bushing in place of the bronze ones which I have not as yet used.

Best to you, John H. Sheally II

With only .001" clearance the front suspension will not move freely.  The kingpin and /or the spindle assembly flex enough under the wieght of a +4 or a +8 to sieze and not move if there is any less than  .005" clearance.  With .003" clearance, a +8 suspension will not move up and down with the weight of the car on the suspension.  We set them up with a hone to .005" and don't bother with any grooves, they are not necessary.  The .005" clearance is enough to allow the grease to fully lubricate the bushings. We also recomend not using the oiler.  We recommend greasing the kingpins every 1,500 miles.

Hi Lorne,

We ream them to "feel" (0.005" wrist?) and DO use the oiler.  We also like to install an "O" ring at the bottom to keep the dirt out and the oil in.  .
