Inserting seal ring and correction jig.

the seal ring on the piston quickly, easily and accurately without damaging the seal ring.
Bushing removal jig

Note: For the above Part No. the tube diameter is 120 mm.

Because the bushing is press-fitted by the hydraulic press at the central part of the cylinder head, it requires a lot of time and

cylinder head.
