Engine Case Splitting – On the Stand

The biggest problems we set out to solve was having to move a heavy short block by hand from an engine stand to a workbench to allow a mechanic to split the cases. By designing our engine adapter with robust 3/8-inch steel plate, the left side brace is optional regardless of the assembly state of the engine. It is included as a belt + suspenders approach.

Short Block Assembly

The right-hand side of the cases can remain on the engine stand, this allows the engine builder to place the crank / pistons / o-rings into the case half before assembling the left hand side of the engine.

Piston Pin Access

The Company23 engine adapter has been designed to allow ample clearance to the rear piston pin access ports while the engine is on the stand.

Access Cut Outs

Because we are Subaru enthusiasts, we understand even the smallest frustrations. To combat everything we could, we included cut outs for screw access on the rear oil separator plate, and for certain year engine mounts.
