ZF Announces Improvements

In Four Marine Transmissions

ZF of North America has an- nounced reliability and horsepower capacity improvements in four of its marine transmission models.

SKF® keyless taper. This design modification improves the reliabili- ty and increases the horsepower ca- pacity of the transmissions.

The improvements have been made to the IRM 301 PL-2, IRM 301 A-2, IRM 320 PL-1 and IRM 320 A-l transmissions.
