 Hey Jack,What a great story!=C2=A0=C2=A0IFF I recall correctly, when I reb=

I'm just curious.

=C2=A0 The purchasing manager introduced me to the rep, and during the cour=

 the time.=C2=A0 I had recently experienced problems getting Vandervell cam=
 bearings and asked him about the status of bearing supply for the TR engin=
e.=C2=A0 He said he would look into it.
A few weeks later, our purchasing manager walked into my office with a big =
box and said, "this is for you".=C2=A0 He told me that the Vandervell rep h=
ad gone back to the UK and had one of his materials managers gather all of =
the TR-2/4 cam bearings from all of their major warehouses in the UK, and s=
ent them to me.=C2=A0 There were over 100 bearings.=C2=A0 Since they were a=
ll the wide bearings, I had about a third of them cut down to the width of =
the narrow bearing.=C2=A0 To make sure the oil holes lined up with the hole=
s in the block, the machine shop had to cut an equal amount off each side o=
f the bearing to get the appropriate width.

Where is all this going?=C2=A0 Well, I changed the cam bearings (because I =
had them) every time I rebuilt an engine, which was about every 4 races.=C2=
=A0 For whatever reason, I kept a number of the used bearings with 4 race w=
eekends on them (or less).=C2=A0 I have a total of 17 wide bearings, plus o=
ne new wide AE bearing, and 9 narrow bearings, or about 9 sets.=C2=A0 I don=
't know if anyone is interested in running used bearings in your race engin=
es, but if you are, I am offering them to anyone on the list for the price =
of the shipping cost.=C2=A0 The wear in these bearings is visible (see pict=
ures), but barely perceptible when you run your finger over the areas of we=
ar.=C2=A0 About what you would expect after 3 or 4 pace weekends.

What is the benefit of Vandervell cam bearings?=C2=A0 The AE or all the oth=
er bearings that are on the market today (to my knowledge) have a straight =
split in the bearing, which can result in the ends of the bearing becoming =
misaligned.=C2=A0 The Vandervell bearing has a design that looks like a jig=
saw puzzle piece, where the ends of the bearing are clenched together, prev=
enting misalignment.=C2=A0 In the third picture attached I tried to get a g=

how many you want.=C2=A0 Thanks.
