A907E1191F — Crankshaft V-Belt Pulley, Single Groove — Lotus 907 / 912

Original Lotus single-groove crankshaft V-belt pulley, part number A907E1191F, for Lotus 900-series engines using the single accessory-drive configuration.

This pulley mounts to the front of the crankshaft and is keyed to the crank with the original Woodruff-key arrangement. It is used to drive the engine accessory belt on applications that do not require the additional pulley grooves used for air conditioning or power steering.

Factory Lotus parts documentation identifies A907E1191F as the single-groove crankshaft pulley. Depending on model and market specification, Lotus also used twin- and triple-groove crank pulleys where additional accessories were fitted.

Typical applications include:

• Lotus Esprit S1 — 907
• Lotus Esprit S2 — 907
• Lotus Esprit S2.2 — 912
• Lotus Elite — 907 / 912
• Lotus Eclat — 907 / 912

This pulley is appropriate only for vehicles originally equipped with the single-groove crank pulley configuration. Cars fitted with certain air-conditioning or power-steering systems may require a twin- or triple-groove pulley instead, so buyers should compare their existing pulley and accessory arrangement before ordering.

This is a genuine used Lotus part, not a reproduction. The pulley has been cleaned and inspected and is in good reusable condition. The keyway, belt groove, hub, and mounting surfaces should always be checked against the buyer’s existing component before installation.
