The Problem

A Global Gold Miner turned to Geographe to help resolve the issue of hoist pin (OEM ref 237-0417) seizure on their CAT 793 D and F model haul truck fleet.  Work on site was forced to stop whenever there was a pin seizure in the frame and they were looking for a resolution to this issue.  Furthermore, the need for hot work upon pin removal added an additional cost and safety concerns.

Caterpillar 793 Haul Truck Hoist Pin Modification

The Solution

By adding lubrication grooves and grease nipples that can connect to a grease line, this direct replacement for Pin 237-0417 now allows the part to be lubricated.  This modification helps increase the pin’s lifespan and eliminate the need for hot work upon removal.   Geographe has since created full Hoist Pin Kits to suit the CAT 793 D and 793 F for easier servicing. 

These Hoist Pin Kits can be customised to your site requirements to include Nuts, Bolts, Washers, Clamps, Pad Assemblies, Bosses, Spacers, and Shims as well as the Modified Pin shown above.

As part of our continuous improvement process, we are currently working on colleted pin assembly designs for the same machine area.  Read 10 reasons why Geographe colleted pin assemblies lowered total cost of ownership on Komatsu 830E haul trucks.
