HMT1500 Imperial Cassette, 1 9/16" Hexagon AF Size
The Enerpac HLP1109 is an imperial cassette for the HMT1500 drive unit. It has 1 9/16" hexagon AF size.
The HLP cassette assemblies include a hook feature as part of the body assembly. This is inserted around the top retaining pin of the drive. The cassette assembly rests along the base of the drive unit body. At this point, the bottom retaining pin holes in the drive unit body and cassette assembly will align, allowing the bottom retaining pin to be inserted fully to secure the two together.
