Our IPD Tech Support group receives many requests concerning what the proper piston to cylinder wall clearance should be in 3114, 3116 & 3126 engines. Originally, these are “parent bore” engines (non sleeved), in many cases requiring re-boring and repair sleeve installation to return bore to proper specifications. IPD also offers money saving oversize .50mm pistons for many popular applications, including both aluminum pistons and IPDSteel™ articulated pistons.
The attached Technical Bulletin outlines our piston information and bore sizes for both the standard and.50mm bore option. We urge you to pass this on to your machine shops, engine rebuilders and engine owners. Click here to view IPDTB-0010
