Q & A: Housing Bore Sizes
Sunday March 17th, 2002
Mr. Twist,
My name is Pete Ingwersen, AMGCR #1295 (I think), and I have my MGC engine in the shop for a complete rebuild. One question the shop has that the manual does not answer is the following: What are the housing bore sizes of the Main Caps and the Big End Rod Caps? These are not the journal or bearing diameters, but the actual diameter of the hole formed by the block and cap or rod and cap in which the bearing set. Where can I find these specifications? I need them in a hurry. Can you help me? Thanks for your time.
Pete Ingwersen
PETE!
The housing diameter for the main bearings is: 2.5210 - 2.5215
The housing diameter for the big end is: 2.1140 - 2.1145
This is not an uncommon question! Hope this helps!... read more

Tip of the Day
It makes no difference how quickly your MG will accelerate if it cannot
stop! The proper functioning of your brakes must ALWAYS be at the
top of your list of priorities. You owe this degree of safety to yourself,
your passenger, and all others on the road.
John H. Twist (Fall, 1980)
