Crankshaft journal being ground on a crankshaft grinder

Lonsdale, Adelaide

Crankshaft grinding in Adelaide

Crankshaft grinding and crack testing at our workshop in Lonsdale, in Adelaide's southern suburbs, along with the rod and piston work that goes with it.

The process

What’s involved.

The crankshaft turns the up and down motion of the pistons into rotation, so its journals need to be smooth, round and the right size.

  1. Step 01

    Crack test

    A crank is crack tested before grinding, so time and money are not spent on a crank that should not go back into service.

  2. Step 02

    Measure

    The main and big end journals are measured for wear, taper and out of round.

  3. Step 03

    Grind

    Worn journals are reground to a true, smooth finish, undersize to suit the matching bearings.

  4. Step 04

    Rods and pistons

    Gudgeon pins are fitted to the con rods and new pistons fitted to suit the freshly machined bores.

Why crack test a crankshaft before grinding?

A cracked crank should not go back into an engine. Testing first avoids spending money grinding a crank that cannot be used.

Do you fit pistons to rods?

Yes. Con rod pin fitting and fitting pistons are both done in house.
