Cylinder Wall Honing

Special Tools:

1. CAUTION: When honing the cylinder bores, use a lubricant mixture of equal parts of kerosene and Super Premium SAE 10W-30 Motor Oil X0-10W30-QSP or equivalent meeting Ford specification G-M2C153-G.

CAUTION: After the final honing and prior to checking the piston fit, thoroughly clean the cylinder bore with a detergent and water solution. Then lightly coat the cylinder bore with Super Premium SAE 10W-30 Motor Oil X0-10W-30-QSP or equivalent meeting Ford specification WSS-M2C153-G.

Note: Before any cylinder bore is honed, all main bearing caps must be installed so that the crankshaft bearing bores will not become distorted.

Note: To correct taper or out-of-round, bore the cylinder block.

Note: Honing should be done when fitting new piston rings or removing minor surface imperfections.

Hone with the Engine Cylinder Hone Set, at a speed of 300-500 rpm and a hone grit of 180-220, to provide the desired cylinder bore surface finish of 18-38 AA.
