Snoop's Take

The E-cowlboy Flywheel Locking Tool with 36mm 3/4’’ Socket is designed specifically for 6.6L Duramax engines, allowing users to securely lock the flywheel in place while removing the harmonic balancer. This tool not only saves time by eliminating the need to remove the starter for water pump replacement but also simplifies the process for different Duramax truck models. Consumer feedback highlights the tool's effectiveness and affordability, with one user noting, "Needed a flywheel holding tool, but couldn’t find one cheap enough locally, so I made one. Works mint." Additionally, users appreciate its functionality for harmonic balancer removal, stating, "This guy fixes." However, some users have commented on the tool's design, remarking that it seems "over-engineered much" but still respect its quality. Overall, the E-cowlboy Flywheel Locking Tool is highly recommended for anyone working on 6.6L Duramax engines due to its effectiveness and cost-efficiency, making it a valuable addition to any mechanic's toolkit.

Hidden Hero Hacks

Unexpected tricks and side‑door uses you’ll love.
DIY solutions for flywheel turning tools are discussed.
All you have to do is sacrifice a starter, a socket, and do some cutting and welding; and you too can not buy the $50 tool off of Amazon.
You can also turn it over with a prybar a tooth at a time haha but hey if you have time to kill.
That’s exactly what I was trying to avoid lol and I’m pretty sure it was faster to build this anyways.
For 60 dollars you can get the combo mp7 & 8 tools.. lol.
Creative DIY methods for clutch alignment
I fill em with grease and then hammer in clutch alignment tool. Never failed me yet.
but you gotta admit, this one is pretty creative!
Bread and a punch or socket work also.
