Crank Seal Replacement


Recommended Posts

So I took apart my Metralla 5 speed motor a few months ago. Just ordered parts and am ready to put back together. I pressed the clutch side crank bearings on the shaft and into the case. For the crank seal there is an aluminum piece that the seal fits into and a steel race that goes over the crankshaft and that the seal rides against. Should this race fit into the aluminum seal holder flush or does is there a space?

Before you fit the steel race (top hat bush) make sure you have replaced the "thin" o ring that sits next to the main bearing. I do not think the race is supposed to be flush with the seal holder, all will become clear when you put the clutch back together as the race is a spacer that will allow the primary drive chain to line up.
