Don't risk expensive engine damage because of a missed shift caused by worn dog clutch rings. If your dog ring lugs have rounded to more than 25% of the lug height, or if they are no longer visibly tapered, they should be replaced. This is the narrow tooth style, designed for easier gear engagement. These dog rings work in Hewland and Webster Mk 4/8/9, Staffs, and Formula Mazda gearboxes. Hewland part number HC232.

We also offer the Webster version of this Dog Clutch Ring, Part No. 1410-A47.

We also offer Dog Clutch Rings for LD200 Gearboxes, Part No. 1422.

Comments about Hewland Dog Ring (Clutch Ring) for Mk-Series Gearbox:

Bought a pair for spares. These parts typically don't catastrophically fail,
but if one did, you won't find a replacement at NAPA Auto Parts after towing 1,000 miles from home. Highly recommended to keep replacements on hand, particularly if you don't know the condition of the parts in your gearbox, or if yours are several seasons old.
