<html><body>Hi Mark-had a similar problem with my early 100. The pulley mounted to the generator turned out to be the wrong one and the belt lineup was askew. The correct one shown is I believe about 3.25" and runs true. Since there were so many of these blocks used on A70, A90 and other saloons of the period, I could see how they got mixed up.

<p class="MsoNormal"><span lang="en-us" style="font-size:10pt;font-family:Tahoma, sans-serif;">The pulley on my
1956 BN2 is 3½” diameter. I believe it to be original.
I’ve owned the car for 45 years.</span></p>

<p class="MsoNormal"><span lang="en-us" style="font-size:10pt;font-family:Tahoma, sans-serif;">A friend has a
BN1 with a pulley diameter of just 3”. He thinks it is
original. I don’t. It got me thinking.</span></p>
<p class="MsoNormal"><span lang="en-us" style="font-size:10pt;font-family:Tahoma, sans-serif;">I believe his is
incorrect as it was converted here in NZ from a LHD import some 30
years ago. BN1L 226180</span></p>
<p class="MsoNormal"><span lang="en-us" style="font-size:10pt;font-family:Tahoma, sans-serif;">The car has some
clumsy conversions made to change it to RHD, so I don’t know what
else might have been ‘cobbled up’ to get the car on the
road.</span></p>
<p class="MsoNormal"><span lang="en-us" style="font-size:10pt;font-family:Tahoma, sans-serif;"> </span></p>
<p class="MsoNormal"><span lang="en-us" style="font-size:10pt;font-family:Tahoma, sans-serif;">Can somebody of
you please confirm that 3½” is correct.</span></p>
<p class="MsoNormal"><span lang="en-us" style="font-size:10pt;font-family:Tahoma, sans-serif;"> </span></p>
<p class="MsoNormal"><span lang="en-us" style="font-size:10pt;font-family:Tahoma, sans-serif;">That said, I
need another for a second 100 engine I am building as a
spare.</span></p>
<p class="MsoNormal"><span lang="en-us" style="font-size:10pt;font-family:Tahoma, sans-serif;">They seem to be
scarce down here in NZ, and repros seem to be rather
expensive.</span></p>
