FF1600 Hydraulic Release Bearing Kit, Hewland Mk9

Finally, an annular slave cylinder (hydraulic release bearing) designed to be a "bolt-on" for the Hewland / Webster Mk-series gearbox!

This unit is engineered to fit most Formula Ford 1600 (Kent engine) cars with single-disc 7.25" racing clutches and the standard 2 1/8" gearbox adapter plate. No fabrication is required! The included adapter base bolts to your main case using three holes around the input shaft. Most Mk-series gearboxes already have these holes drilled and tapped -- check your case before ordering.

Requires two 12x1.0mm adapter fittings and crush washers (sold separately). Choose the size you need to match the hydraulic lines you will use:
12x1.0mm to 3AN Steel Adapter (Part No. 3265-42)
12x1.0mm to 4AN Steel Adapter (Part No. 3265-59)
12mm Crush Washers (Part No. 3278-M12, pack of 5)

Replacement parts available:
Rebuild Seal Kit for FF1600 Hydraulic Release (Part No. 163-52)
Replacement Bearing for FF1600 Hydraulic Release (Part No. 163-61, lower right in photo)


Note: Using a Clutch Pedal Stop is critical to prevent damage to the clutch and to the engine!
