Hello,

I have tried to find another year engine or superceding part number for the crankshaft on my 1986 E70TLCD VRO.

Crank bearing on cylinder 1 shredded to pieces and seized motor.

Tore down powerhead and journal is scored on #1..

Cylinder in good condition, piston needs replacement.

Is there another crankshaft I can use in this motor? I found a 70hp Johnson 1994 that is a pats motor and shares same piston/bearing part number’s.

The 94 crank has different spline.----Will not work.

It’s there any crankshaft compatible with my engine? No one near me either has or wants to part ways with their 70hp VRO from 1986.

What is the remanufacturing tolerance for this year/model crankshaft? If scoring is not too deep I may be able to get it polished and still be usable/within tolerance.
