Illustrated Parts Catalog 915 iS C24 Series ROTAX Aircraft Engines

The information and components-/system descriptions contained in this Illustrated Parts Catalog are correct at the time of publication. BRP-Rotax, however, maintains a policy of continuous improvement of its products without imposing upon itself any obligation to install them on its products previously manufactured. BRP-Rotax reserves the right at any time to discontinue or change specification, designs, features, models or equipment without incurring obligation.

This Illustrated Parts Catalog is not an offer to sell parts, but a catalog illustrating the parts available at ROTAX® authorized distributors. BRP-Rotax reserves the right to deliver the components (crankshaft, crankcase, special tools etc.) only to organizations with respective qualifications, and thus, these special components will not be listed in this IPC.

Color variations on unpainted castings:
On unpainted surfaces (i.e. aluminium cases) minor color variations (i.e. grey tone on aluminum surface) are possible due to the manufacturing process. Such possible color variations do not affect the quality of the product and are no reason for rejection - even a color variation on castings in differing areas is acceptable.

Tightening torque
Generally all the fasteners on a ROTAX® engine are tightened with a torque wrench. The tightening torque must always be done according to the content of the latest Maintenance Manual Heavy for the respective engine type.

PARTS ORDER Engine serial number
When making inquiries or ordering parts, always indicate the engine serial number, as the engine manufacturer might make modifications to the engine in the course of product improvement. The engine serial number is on top of the crankcase, behind the propeller gearbox.

Indicates supplementary information which may be needed to fully complete or understand an instruction.
In illustrations this sign indicates the position of the current serial number (e. g. on crankshaft, camshaft, etc.). In descriptions (in part no. column) this sign indicates that this part is described in an other chapter.

Exploded view
Each section starts with an exploded view of the type 915 i on the left side. The corresponding heading and the listing of the parts is on the right side and the following pages. The numbering on the exploded view is in the sequence of assembly as much as practicable. For prevention of errors and to simplify exchange we tried best to list the part number of each component only once. But for better understanding components are frequently depicted without being listed, but referred to a respective section, if considered necessary

Engine-column
For each engine type the right amount of spare parts per engine is listed in the relevant engine-column. If the quantity is in brackets it indicates that the part is not absolutely necessary but optional on the respective engine type. A small letter added to the number refers to information at the end of the section. No number in the column parts per assembly indicates that this part is not planned for the respective engine.
