Central tooth 6Y6335R by GX-AFTER. This is a specialized "Shark" (R - Reinforced/Rock) version, characterized by an extended profile and increased mass compared to standard tips. Designed for mounting on 22 mm blades with a hole spacing of 74 mm. Dedicated to extremely difficult operating conditions in Caterpillar (CAT), New Holland, and Fiat-Hitachi/Kobelco backhoe loaders.
GX-AFTER supplies industrial-grade Ground Engaging Tools (G.E.T.) components. Thanks to advanced steel alloys and heat treatment, our teeth offer an optimal balance between surface hardness and core ductility, eliminating the risk of breakage under load.
| Brand | Models (check 74mm spacing) |
|---|---|
| Caterpillar (CAT) | 416, 420, 422, 424, 426, 428, 430, 432, 434, 438, 442, 444 (Series B, C, D, E, F) - Front bucket |
| New Holland | LB75, LB85, LB90, LB95, LB110, LB115, NH75, NH85, NH95 (select models with 20-22mm blade) |
| Fiat-Hitachi / Kobelco | FB90, FB100, FB110, B90, B100, B110 (with 4-in-1 front bucket) |
The list is for reference. It is crucial to verify the mounting hole spacing (74-75 mm) on your machine.
The tooth is mounted using two plow bolts with nuts. Typically, 5/8" or M16 bolts are used. We recommend replacing the bolt set with every new tooth installation.
Working with loose teeth leads to ovalization of mounting holes in the bucket blade. A damaged blade requires costly regeneration or replacement of the entire cutting edge. Regularly check bolt torque.
The 6Y6335R central tooth is the main working element of the front loader bucket, facilitating pile penetration.

The version with the letter "R" (Reinforced/Rock) is longer, more massive, and has a more aggressive profile, ensuring better penetration in hard ground and longer life compared to the short, flat standard.
Usually not. JCB uses teeth with a smaller bolt spacing (approx. 45mm). This tooth (74mm spacing) is typical for CAT and New Holland/Fiat machines.
Typically, teeth are sold separately. Plow bolts with nuts must be purchased separately, matching the length to the blade thickness.
