[Healeys] Part III Knock offs

[gradea1 at charter.net]

Replacement parts-not NOS-what if the knockoff bottoms out on the
spline face before it tightens to the cone of the wire wheel? A
combination of measured errors on replacement parts could create this
condition-front to back. The knockoffs were made to tighten, but not
be whaled upon. If properly applied each side they are self tightening
and I normally spin them on hand tight, hit them with the rawhide snug
while still up in the air, and then wack them one more time on the
ground with the copper side of Thor.
One time in the early '70s I witnessed a BMC "mechanic" whaling on a
knockoff of the Healey, still hanging on the lube rack, with a ten
pound long handle sledge hammer! Flat ears? you betcha.
I would make sure that when mounted, the front edge of the wheel is
just forward of the inner depth of the knockoff so that it actually
contacts metal as it snugs it to the rear ring on the hub. 
Also-grease-not to much- but be sure splines, and ring of hub, and
knockoff threads have a light smear. I use HD wheel bearing grease so
it doesn't seep out the spoke nibs like moly or light grease would.

	Michael et al,

	Contemplate the mechanical connections between the hub extension,
wire wheel hub and the knockoff. 

	The hub extension is bolted to the axle using tapered nuts that seat
in the face of the extension. No rotational movement.

	The wire wheel is connected to the hub extension via the splines. The
tolerances in the splines may allow for some rotational movement but
they have to be loose enough to get the wheel off the extension. 

	What else holds the wheel in place…the knockoff. The cone in the
knock off forces the wire wheel hub against the hub extension, The
contact interface is the tapers on the hub extension and the wire
wheel hub. You know the little area that we are frequently reminded to
apply a smear of grease to stop the little squeaky noise at low speed.
If the knock off is tight enough there is not movement here either.

	So Mike, if you see movement between the knock off and the wire
wheel, the knock off is not tight enough. 

	Suspect that the folks that developed knock offs understood the
problem of owners/mechanics not getting them tight enough and used the
handed (left and right) threads that self tighten. 

	Gentlemen, remember your Mother today!

	At my age (approaching this side of 70) I am on lock down at my
house. I even have my groceries delivered. I will only go out to eat
at a drive through with an N95 mask on. My Boston Terrier that goes
with me does not wear one. He refuses, but he is only three years old.
So, being sequestered to my domicile I have taken up the restoration
of my BN2 with a vengeance. I did not know I knew so many off color
phrases. Everything to be done on this car is difficult due to parts
incompatibility, parts fit, parts unavailability or just my general
ignorance and/or incompetence. This evening I finished mounting the
right side front hub with all new parts. I thought I had done a nice
job. No lateral play in the hub. Turns easily without binding. The
correct amount of shims after much trial and error. Disc brake
conversion was mounted and braided stainless steel flex brake lines
hooked up at both ends. I have yet to run the brake lines. Maybe next.
This rant is about the brand new Dayton wire wheels. I mounted the
wire wheels which have temporary used tires on them so I can move the
car when it is down off the dollies. After mounting the wheel I gave
the two eared knockoff several pretty good whacks. Now the moment of
truth. I grabbed the wheel at 9 and 3 o'clock position and pulled
straight back and forth. Yay! No play, but when I rocked the wheel it
moved slightly. I thought it was the hub, but looking closely you can
see the wire wheel hub rocking back and forth in the knockoff! What!?!
How hard are you supposed to hit those knockoffs?
