roller bearing R69s

[Eric G]

Hello with all, to install the bearing postpones with barrel on the crankshaft of r69s: the bearing should be heated or press it cold? Thank you.

Hi Eric, Heat the bearing to fit the crankshaft, but heat the crankcase to fit the bearing and crankshaft assembly with the bearing cold.
