Hi Friends,
Today I spent a little time doing the kind of work I really like;
diagnosis.
Here's what the workshop manual says about the XPAG
cylinders:
Bore: 2.6180"
1st over-bore: 2.6381"
Here are the measurements, made just a few minutes ago
on my TD's cylinder #1.
Note: The precision of my instrument is about 0.0003" and
although I repeated the measurements a few times, these
are the numbers I recorded.
#1 Bore inline (top): 2.6390"
#1 Bore inline (bottom): 2.6380"
#1 Bore cross (top): 2.6388"
#1 Bore cross (bottom): 2.6381"
Ovality (top): 0.0002"
Ovality (bottom): 0.0001"
Taper (inline): 0.0010"
Taper (cross): 0.0007"
Initial interpretation:
This engine is on its first over-bore and acceptably healthy,
at least the #1 cylinder's bore.
More measurements and more 'careful' measurements will
be made once the the block is cleaned.
