When timing gears are subjected to extreme temperatures, the aluminum gears do not return to their original dimensions after cooling. The result is a loose fit between the gears and camshaft. Under no circumstances should aluminum gears be heated with a torch.

Pistons are perhaps one of the more sophisticated chunks of metal in the picture. Here’s what you should know.
Most of us are familiar with the Enzo Ferrari quote, “What’s behind you doesn’t matter.” We can all agree the man responsible for these iconic words knew a thing or two about racing. His quote speaks to many of us, on many levels, and it’s the reason we’re driven to always do things better.
What if we could design a new rotary engine that addresses certain limitations without violating the laws of physics? This is what LiquidPiston has been working at for over a decade.
Using modern honing machines, surface finishes, crosshatch angles, ring materials, and coatings all combine to create a more efficient engine.
Connecting rods are subject to constant stress through extreme tensile and compressive loads, each one tied to a different aspect of operation.
The balance of a rotating assembly is critical in every aspect and for every engine.
From the high-performance powerplants propelling Top Fuel dragsters to the subdued engines found in family sedans and grocery getters, each crank must be tailored to, and appropriate for, its specific application.
I always keep a pair of needle nose pliers and a small, straight screwdriver in my blast cabinet to hold small parts when blasting.
