Howard puts a little oil on the rings and on the rod bearings before installation.
Howard uses a ring compressor to install the JE pistons in the bore.
With a good ring compressor, you can just push the pistons in place without having to tap them in. This is a good feel operation and makes it less likely to snag and break a ring.
Howard adds a little oil to the cranks rod bearing journals before installing the rod caps.
The ARP rod bolts threads and bolt heads are lubricated with ARP lube before they are tightened down. This helps assure proper tightening torque.
The rod cap bolts are tightened down to snug, then torqued to spec. Finally, the overall length of the bolts is measured to determine if the proper stretch is reached. Measuring stretch is the most accurate way to determine that the bolts are at the proper torque and ARP provides a stretch spec for their rod bolts.
