It's a diesel engine, no spark plugs.

Use a big screwdriver or through the timing hole to wedge between the flywheel ring gear and the flywheel cover.

Hi thanks Don, have it all apart now...have to replace crank seal..I have removed hub also. I removed worn seal no problems...Question is ..I found a seal case or sleeve (alloy) that looks like it shouldnt be there..between hub and timing cover?
