Tillotson HW Throttle Shaft Finish
Posted by on
To Whom It May Concern,
Tillotson would like to confirm that the surface finish of some HW throttle shafts may vary slightly from the typical production finish, resulting in a duller appearance.
This variation in appearance can occur during the plating process where there is reduced or inconsistent electrical contact with the individual parts. This affects the visual appearance of the finish only.
We confirm that all affected throttle shafts remain within the specified dimensional and measurement tolerances and the difference in finish is cosmetic and does not affect the suitability or performance of the parts.
Best regards,
Andrew Fallon
Product Engineer

Until further notice (the 2024 fiche [...]

The overall length is too short. Some of these have made their way into the U.S. market and have been discovered in several areas (race [...]
Notice: X30 Gearbox Venting
The vent fitting onto the X30 crankcase is provided because the gears compartment (like all the gears compartments) need to be vented. The air contained into the gears compartment is heated by the aluminum walls, by the oil and by the gears themselves, as all these parts are heated up during engine operation. As a result, [...]
