One of the common things we do down here is rebuild rotary engines.
When we rebuild rotary engines, it really comes down to what a customer's after and what the purpose of the engine is.
We are currently rebuilding an RX7 Series 8 engine, which the customer is intending on circuit racing. For that application, we have chosen to go with a stud kit through the housings and through the end plates. This is to increase the rigidity of his motor, and stop twist.
The other thing we have done with his rotors, all of his rotors have been side clearanced, which gives us extra clearance on the side seals and also the corner seals.
We always opt to use new bearings in all of our rotor assemblies, and also in our stationary gears.
The other thing we do, is to have all of our rotating assembly balanced, and we also get our shafts what we call "isotropic coated" to improve strength.
The other thing that is very critical are the oil control rings in the engine. A lot of people fail to replace certain things like oil control rings and the different retaining springs behind them. They must be replaced to maintain the tension in the oil control rings, side seals, corner seals and apex seals.
Apex seals and side seals are pretty much like a piston ring. Apex seals gain a surface against a rotor housing, and the side seals work with the side plates.
