Starter pulley failure

by Had Robinson

Pilots annoyed with the poor quality Viadana pulleys supplied by Miniplane can purchase the superior Harken 082 Single Bullet Block to replace the single pulley on the Top 80.Harken 082 single bullet block  The Thor models also have a second lower pulley with a swivel which is equivalent to the Harken 166 Bullet Block Single with Swivel.Harken 166 bullet block single with swivel




These pulleys have precision stainless steel bearings and come with a (5) year warranty.  They are about twice the cost of the OEM but will never wear out.

Below, a failed Viadana pulley.  The plastic ball bearings quickly wore out and prevented the block from turning whereupon the starter cord quickly cut into the pulley.  Regular oiling will help slow down its eventual destruction.  The Viadana was not designed to service any but the lightest loads.  But they are "100% Italian made" LoL!
