The center piston is attached to the rods first… The outer pistons are inserted into the liners before attachment to the rods. Unfortunately, with non OEM size pistons or wrist pins, the factory tools are useless. This is where the challenge is.

The housing is slid on with the outer two liners already in.

Of course the cylinders are stuffed to prevent the wrist pin clip from falling into the engine as you struggle to attach it.

At least you can use the factory tool to slide the inner sleeve in. Let me reiterate how difficult it was to get these rings in. Extra hands were necessary.

In frustration, time to do something easy. Chain housings and guides.
