Hi Ron-
Several years ago when I got the Lempert gear set installed by Alan's
GearWorks, Inc.in Clearwater, FL, I was given an instruction sheet which I will
quote.
"Because of the slight roughness of the new gear contact faces and the heavy
preloads that must be applied to new tapered roller bearing, your new rear
axle will generate its maximum amount of waste heat in its first few miles.
With use, bearing preloads diminish and gear surfaces become smoother.
Therefore, the first few hundred miles on a new gearset are the most crucial.
To
prevent premature (and almost immediate) failure of your new gearset, this
break-in procedure must be followed.
Recommendations for proper break-in are:
1)Keep drives short (less than 10 miles) for the first 100 miles.
2)Keep road speeds below 50 MPH for the first 100 miles.
The intent of this procedure is to prevent overheating of the gear
lubricant. Its lubricating qualities can breakdown at high temperatures and any
loading of the gearset, under these conditions, can cause irreparable damage."
I hope this will be of some benefit to you and anyone who is in need of the
break-in instructions.
After the gearset was installed in my BJ8 "Blackie" and the break-in
procedure followed, we took our first trip from St. Petersburg, FL to South
Lake
Tahoe, NV for the Open Roads-Healey International 2002. The total trip
distance
was 6,060 miles and I must say that I was a pleasure to be able to cruise
with the "Big Boys" (18 wheelers) without feeling like the engine was being
overstressed continually .
My personal thanks to Mike Lempert for making these gears available to a
number of the Healey drivers that have really appreciated and enjoyed them
also.
