Pistons & Crank

Pistons & rings removed

Ringlands were quite nice condering the KM's!
Removed & labelled the pistons and just gave everything a visual inspection prior to cleaning



My first attempt at cleaning the pistons did not go as planned. As usual, I dunked the dirty parts in E85 overnight

Resulted in not much of a difference

Then I tried Simple Green dilluted 50:50 for 10 minutes

Ended up doing so much in such a short time

I liked the simple green so much that I ended up cleaning the replacement block with it.

Before



After



Installing the balance shaft delete kit that blocks off ports from the main cap girdle which sends oil to the balance shaft bearings

Cleaning the block/crank for new bearings/rings




Checking ring end gaps (new rings are NPR replacements in standard diameter)


Positioning pistons to clock rings (a sharpie through the middle makes this easy)

Piston compressor oiled and over the rings

Pistons in


Lower main bearings and piston bearings in

Lubed up with assembly lube

Crank in

Getting main caps/bridge ready to install

Rod caps

All in and torqued down
