  1. Crank Seal Replacement

    bsaben posted a topic in Bultaco
    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?
