Type HA is available in various sizes to suit the small and medium range of Trelleborg Industrial AVS mountings, as listed in the table below. It allows mountings to be retrofitted to existing installations where original spares are unobtainable.

• For optimum solutions where close coupling tolerances are required, allow the mountings to settle for 48 hours before final alignment of the engine installation.

Type HA is a height adjuster made in corrosion protected grade 8 steel. The steel is zinc plated and chromated according to DIN 50691/ISO 2081. The height adjuster is supplied complete with washer and nut for fastening to the mounting and two nuts and a lock washer for the engine foot fastening. The HA height adjustment facilitates precise coupling alignment for engine installations and boat building tolerances.

Note: For all applications with Thrust loads HAD type height adjusters must be used
