As promised, please find attached a link to the FB/EK Holden 3-speed Crashbox Enthusiasts Guide:
My apologies for taking so long with this one - I kinda got distracted with floor shifters
.This document aims to provide some information regarding three-speed manual gearboxes (crashboxes) suitable for FB and EK Holdens. It contains:
• historical information, such as which gearboxes and fittings were fitted to different model Holdens,
• practical information on identification, disassembly and reassembly of early Holden gearboxes,
• guidance on adjustment, maintenance, replacement parts and overhaul techniques, and
• information on accessory floor shifters.
It contains answers to many of the questions that seem to come up routinely on most of the early Holden forums:
“What overhaul parts are available for my early Holden crashbox, and where do I get them from?”
“Why is my crashbox jumping out of gear?”
“What oil should I run in my crashbox?”
Whilst this document is primarily related to the FB and EK Holden gearboxes, much of the information is similar or identical to other early Holdens. This document also contains a significant amount of information related to floor shifters. My original intention was to cover only those floor shifters which fit the grey motor crashbox. However, as always, the more I dug into aftermarket floor shifters the more interesting things got... and I got a little carried away. Section 9 now contains some interesting historical information, and has information relating to floor shifters of the “three-on-the tree” era (FX-WB Holdens) rather than just being limited to grey motors.
Happy to field any queries or corrections.
Cheers,
Harv (deputy apprentice crashbox fiddler).
