Description
SST-45 Gear Case Specialty Tool β Build the Tools Needed for Proper SST45 Racing Gearcase Service
The SST-45 Gear Case Specialty Tool Specifications Manual provides the measurements, dimensions, and fabrication information needed to make the specialty tools referenced throughout the SST-45 Gear Case Repair & Rebuild Manual.
Many of these tools were never manufactured or NLA (No Longer Available). This manual gives racers, engine builders, and machinists the information needed to fabricate the tools themselves or have them professionally machined.
For anyone who plans to service, repair, or completely rebuild an SST-45 / Formula Light racing lower unit, this manual is an important companion to the gearcase repair manual.
Designed to Work With the SST-45 Gear Case Repair & Rebuild Manual
The SST-45 Gear Case Repair & Rebuild Manual references specialty tools required for certain disassembly, installation, inspection, and assembly procedures.
This specialty tool manual provides the specifications needed to create those tools.
Together, the two manuals provide a more complete technical resource:
- Gear Case Repair & Rebuild Manual β Explains the service and rebuild procedures
- Specialty Tool Specifications Manual β Provides the dimensions needed to fabricate the tools referenced in those procedures
This makes it much easier for racers and shops to perform gearcase work without having to locate discontinued or hard-to-find factory specialty tools.
Make the Tools Yourself or Have a Machinist Build Them
One of the biggest advantages of this manual is that it gives you the flexibility to produce the tools locally.
The specifications can be used to:
- Machine the tools yourself
- Have a local machine shop fabricate them
- Replace a lost or damaged specialty tool
- Build a complete SST-45 gearcase service tool set
- Create spare tools for a race shop or team trailer
- Reproduce specialty tools that may no longer be readily available
For many SST-45 racers, being able to fabricate the correct tool is far more practical than trying to locate an original factory tool years later.
Why the Correct Specialty Tools Matter
The SST-45 gearcase contains precision-fit bearings, shafts, seals, gears, and machined surfaces.
Trying to substitute punches, screwdrivers, generic pullers, or improvised shop tools can result in damage to:
- Bearing races
- Gearcase housings
- Shafts
- Seals
- Threads
- Bearing surfaces
- Precision-fit internal components
Once a machined surface or housing is damaged, a straightforward rebuild can become a much more expensive repair.
Using a tool built to the proper dimensions helps apply force and support in the intended location.
Key Features & Benefits
- Provides Specialty Tool Dimensions β Gives the specifications needed to fabricate SST-45 gearcase service tools
- Companion to the Repair Manual β Covers tools referenced in the SST-45 Gear Case Repair & Rebuild Manual
- Allows Local Fabrication β Tools can be made in-house or by a machine shop
- Helps Replace Hard-to-Find Factory Tools β Especially useful when original specialty tools are unavailable
- Supports Proper Gearcase Service β Helps racers use tools designed for specific repair and rebuild procedures
- Reduces Improvised Repairs β Less dependence on punches, makeshift drivers, or incorrect pullers
- Useful for Race Shops β Helps teams build and maintain their own SST-45 gearcase tool inventory
- Ideal for Long-Term Support β Once the specifications are available, replacement tools can be reproduced as needed
Useful for SST-45 Gearcase Repair & Rebuilding
The specialty tools referenced in the repair manual may be used during procedures involving:
- Gearcase disassembly
- Bearing removal
- Bearing installation
- Seal installation
- Shaft service
- Internal component removal
- Component positioning
- Gearcase reassembly
- Complete lower unit rebuilding
The exact tool required depends on the procedure being performed.
A Valuable Resource for Machinists
This manual is not only useful for racers and mechanics.
It is also valuable when working with a machinist who may not be familiar with SST-45 racing gearcases.
Instead of trying to explain what a specialty tool should look like from memory, the manual gives the machinist the dimensions and reference information needed to fabricate the tool to the proper specification.
That can make communication easier and reduce trial-and-error fabrication.
Ideal for Racers, Builders & Race Shops
This manual is especially useful for:
- SST-45 racers
- Formula Light teams
- Race engine builders
- Crew chiefs
- Marine mechanics
- Machine shops
- Racers building their own specialty tools
- Teams maintaining multiple gearcases
- Shops restoring or rebuilding older SST-45 lower units
Why This Manual Is Especially Valuable Today
Many specialty tools used for older racing gearcases can become difficult to locate over time.
Original tools may be:
- Discontinued
- Difficult to find used
- Expensive when available
- Damaged or incomplete
- Missing from older race shops
Having the actual tool specifications gives racers and mechanics another option: simply reproduce the tool when needed.
That can be especially important for keeping older SST-45 racing equipment serviceable for years to come.
Race Reliability Starts With Proper Service Equipment
At Liquid Revolutions, we know that the SST-45 gearcase is a specialized piece of racing equipment and that proper service often requires more than standard marine hand tools.
The SST-45 Gear Case Specialty Tool Specifications Manual gives racers and builders the information needed to reproduce the tools called for in the repair manual, making it easier to properly service and rebuild these lower units.
Whether you’re building a complete SST-45 gearcase service setup, replacing a missing tool, or working with a machinist to reproduce one, this manual provides the specifications needed to get started.
