Diehl Accessory Case and Components
for your VW Engine!


Diehl Accessory Case Picture


Since 1979, the Diehl Accessory Case has been providing accessory attachment and engine vibration isolation for VW powered homebuilt aircraft. The Diehl Accessory Case is very distinct from others that are manufactured by other companies.

The Accessory Case is made from Tenzalloy, not just magnesium. This gives the case much more flexibility and retards ignition. Ever seen magnesium burn? Sparklers!

Our NEW Flywheel is made from 100% steel. Experience has shown that many aluminum flywheels will fail around the dowel pin holes. In 26 years, we have not had one known flywheel fatigue failure from cracking. Our flywheels are lightened to about 6 pounds, balanced and bead blasted when done. They are the lightest steel flywheels available today. (Note: Flywheels for the Reduction Drive System are re-manufactured meaning that the teeth aren't new.)

We were the first to initiate the use of a Geared Hi-Torque Starter for positive engine starting. Our competitors of course followed. Our geared starter provides 4 times the cranking power when compared to the older non geared starters. (Note: Starters are re-manufactured.) The Diehl Accessory Case utilizes a 109 tooth ring gear. A VW Starter does not fit with the Diehl Accessory Case.

We introduced the moulded ceramic based Magnet Ring for the 22 AMP internal alternator. This state of the art magnet ring eliminated the problem associated with steel caps coming loose off magnet rings.

You can order the entire unit as a package and save a few dollars or you can order the items individually. The flywheel is available to fit either 4 or 8 dowel crankshafts. We also have replacement flywheels, mag drive, starter and alternator conversion kits for older HAPI and Mosler engines. Call for pricing!
