Fits Models At A Glance:

• Caterpillar Backhoe Loaders: 420E, 430E, 446, 446B

Key Notes:

• Part Number: 8T7004 (Caterpillar reference 8T-7004)
• Position: Taperlock Wheel Stud
• Thread: M10 x 1.5
• Length: 35 mm
• Style: Taperlock - the shank seats on a taper rather than a plain press fit
• Weight: 1.0 lbs.
• Condition: Aftermarket replacement part
• Application: Replaces a taperlock wheel stud on Caterpillar 420E, 430E, 446 and 446B backhoe loaders
• Shipping Restrictions: Ships to the lower 48 US states only
• Note: Sold as a single stud; nuts are not included. This is a TAPERLOCK stud - the seat is tapered, so it is not interchangeable with a straight press-fit stud of the same thread. Caterpillar catalogues it against a very wide range of machines beyond backhoes, including graders, articulated trucks and large loaders. The shipping weight shown is the supplier's figure and is high for a stud this size.

Common Use Case or Symptoms:

Replace these when a taperlock stud spins in its seat, has sheared, or the taper has pounded out so the stud no longer draws up tight - a taper that has been run loose does not clean up, and a stud that turns in the hub will never hold torque again.

Why Choose Broken Tractor?

• ✅ Taperlock Not Press Fit: The tapered seat is what makes this stud different from a plain M10 - fitting the wrong style leaves a joint that will not stay tight.
• ✅ Small Thread Big Consequence: M10 x 1.5 at 35 mm is a light stud carrying real wheel load, which is why they are replaced as a full set.
• ✅ E Series And 446 Coverage: 420E and 430E backhoes alongside the 446 and 446B.
