CRANKCASE COMPLETE

Complete crankcase casting from the 1968 catalog listing, the main lower-end housing for the crankshaft and bearings.

PN · 70-8000

70-8000 is the complete crankcase assembly, listed in the crankcase figure of the parts book. This is the main engine casting that holds the crankshaft, main bearings, and the lower end of the motor together, the foundation everything else in the bottom end bolts to or runs through.

Our catalog record shows this one appearing under the 1968 listing, with E8000 as the older-style part number for the same casting. Beyond that the record doesn't spell out which specific model it was fitted to, so if you're trying to match this against your motor, give us a call and we'll work through it with you before you order.

A crankcase is not a part most people swap casually, given everything that has to line up with it, so if you're sourcing one for a rebuild it's worth confirming bearing bore sizes and stud patterns against what you're pulling off the bike.
