Mcculloch crank identification

Post by travis stevens » Thu Oct 12, 2017 10:00 pm

Part number on the crank is 47799 I do know it's a super series crank due to it being shorter than a 91 crank just wondering if anyone knows the part number and can help me out with the fitment of the crank

Travis,

# 47798 crank is MC 70, 75 and 100. Pretty sure the stroke is the same as a 101 but the bearing at the block is different

Hi Travis:

Most Mac cranks are stamped on the flat side of the counterweight on the flywheel end as pictured.
