Front end loader bucket teeth: the measurements that matter
A loader bucket tooth looks simple until you try to replace one. The teeth are not interchangeable between buckets, and the retention system varies more than on an excavator.
Naming: front end loader, not wheel loader
Both names describe the same machine. In North America the everyday term is front end loader; in Europe and in most specifications it is wheel loader. Parts listings use both, so search both before concluding a part does not exist.
Three measurements, same as an excavator tooth
- Pin or bore diameter — measured at two perpendicular axes. A worn bore is oval; take the smaller reading.
- Opening width — between the inner faces where the adapter seats.
- Overall length — pin centre line to tip.
All three must match. Two teeth with the same pin diameter can differ in opening width.
What differs from an excavator
- Bolt-on tooth bars. Many loader buckets use a bolt-on bar rather than individual welded adapters. If yours does, the hole pattern on the bar is the fitment dimension, not the tooth pin.
- Bolt-on versus weld-on adapters. A weld-on adapter replacement requires cutting and welding; a bolt-on does not. Know which you have before ordering, because it changes both the part and the labour.
- Wider variety of retention. Loader teeth use pin, bolt, and flex-pin systems, and these do not interchange.
What to check before ordering
- Is the tooth pinned to a welded adapter, or bolted to a bar?
- How many teeth does the bucket carry? A set price is not comparable to a single-tooth price.
- Are the adapters worn? A new tooth on a worn adapter fits loosely and wears fast.
