Re: Square 4 big end shells

Many thanks

The next question is can someone recommend someone near Junction 11 of M25 to regrind the crankshafts?

Also does anyone have the sludge trap screws 1190-37 (I believe they are 1/4" 26 TPI BSF x 7/16" CSK)?

Regards, Simon

Square 4 big end shells

Hopefully someone will be able to help me. The specification for the crankshaft big end journal is 1.3745" to 1.375" (which is a very tight tolerance) I am thinking of fitting a Morgo oil pump and I am measuring 1.370", 1.373" , 1.373" & 1.374" on the 2 crankshafts....
