AMF Shovelhead Lowrider Restoration -19 - Piston, Ring and Cylinder Installation

In this the 19th chapter in the series, the casting on the pistons will be corrected along with a few measurement before we finally mount everything onto the engine. I took exception to the raised numbers on the face of the piston as well as the shotty ends of the valve reliefs. A dremel with polishing paste made quick work to soften these jagged edges that could cause hot spots in the combustion chamber. This was followed by a quick wrist pin measurement, by request and significant washing. Funny thing, these pistons have no indication as to placement, though not entirely symmetrical on the underside, having addressed this years ago, I reviewed older footage to make this determination. As the pistons are marked, I use the pins to check the wrist pin bushings with oil, pre staging the keepers on one side. All surfaces lubed, the pistons are mounted onto the rods followed by the second keeper. The rings are pre oiled and loaded onto the pistons. I take a moment to prepare a few dowels with supper 88 that will be used to steady the pistons during the loading of the cylinder. The dowels are set up under the pistons providing a secure platform. Correct cylinder, gasket and the placement is checked and rechecked. A process of cleaning is done to ensure the cylinder is perfectly clean inside and out. Dried and oiled as to not flash rust. The oil rings are checked for no overlap, sliding freely. Side clearance is checked and the correct opening skew between the rings is checked. Ive washed a rubber mallet and a ring compressor. oiled everything completely as the compressor is staged, the cylinder is lowered onto the chamfered margin, light taps with the mallet drop the cylinder over the rings, before the cylinder is completely lowered, the one bolt on each side for the heads is pre-loaded. The cylinder is then lowered down to the studs. A dust cap is assembled with newspaper and oil. The triangular washers and new base nuts are placed on. Once both cylinders are at this point torquing is begin. Front pullie components are re added temporarily so that the engine can be rotated. A flathead driver keeps the triangle washers centered as the base nuts are torqued. Using a cross pattern, 20, then 36 on both cylinders. Completing this chapter. #shovelhead #amf #harleydavidson
