Caterpillar 1U-3352 Bucket Tooth (J350)

What Cat Says About This Tip

Cat's own page for 1U-3352 describes it in one line: the J350 general purpose bucket tooth is designed to penetrate and loosen soil and rocks. It carries the same family wording as the rest of the J series — industry-standard side-pinned design, quick installation and removal with the standard pin and retainer system — and is rated standard for wear and durability, with general excavation and loading listed as the application.

The number that separates it from every other J-series tip is the pin: 19 mm diameter, 108 mm long. J250 and J300 both run a 14 mm pin, at 78 mm and 92 mm, so a caliper across the pin tells you in five seconds whether you are holding a J350. On the Cat side the pin is listed as the 19 mm grooved pin 114-0358 with the 19 mm J350 retainer 114-0359; aftermarket wear-parts catalogues quote pin 9J2358 with retainer 8E-6359 for the same system.

The Three General Purpose Sizes Side by Side

Part number	Tip size	Overall length	Front width	Pin	Catalogue weight
1U-3252	J250	7.48 in / 190 mm	2.52 in / 64 mm	14 mm × 78 mm	~2.8 kg / 6.2 lb
1U-3302	J300	8.465 in / 215 mm	3.15 in / 80 mm	14 mm × 92 mm	~4.3 kg / 9.5 lb
1U-3352	J350	9.449 in / 240 mm	3.543 in / 90 mm	19 mm × 108 mm	~6.2 kg / 13.7 lb

Dimensions are from Cat's published part pages; millimetre figures are our arithmetic at 25.4 mm per inch. Weights come from aftermarket catalogue listings rather than from Cat, and describe the standard profile casting. The pattern is regular — each family up is about 25 mm longer — which is exactly why the tips get confused on a bench and why the pin measurement is worth taking.

Hardware and Adapters That Go With It

Item	Number	Size / note
Pin (Cat listing)	114-0358	Described by Cat as a 19 mm grooved pin
Pin (catalogue)	9J2358	19 mm × 108 mm per distributor wear charts
Pin retainer	114-0359	Described by Cat as a 19 mm J350 pin retainer
Pin retainer (alt)	8E-6359	Listed by Cat in the same group as this tip
Weld-on adapter	6I-6354	Listed by Cat with 1U-3352; J350 nose required

Every profile in the J350 family — general purpose, rock chisel, tiger long — runs on that same 19 mm pin and retainer set, so a mixed box needs one hardware number rather than one per profile. Ship one pin and one retainer per tooth, plus spares for the field: a walk-out pin costs the tooth as well, and the tooth is the more expensive half.

Other	EL200B, EL240B / EL240C, E240 series excavators; 227 logger; 633E wheel scraper

As with every J-series part number, that list is Cat's own and it is longer than most people expect: 966 and 980-class loader buckets and 320D2-class excavator buckets both appear against the same tip. It tells you where the tip can be found, not what is on your machine today. Confirm the pin and the adaptor nose, then quote against those.

FAQ

Q: What pin and retainer does a Cat 1U-3352 tooth take?
A: A 19 mm pin, 108 mm long. Cat lists the grooved pin 114-0358 with 1U-3352 and describes 114-0359 as a 19 mm J350 pin retainer, with 8E-6359 in the same group; aftermarket catalogues quote pin 9J2358 with retainer 8E-6359. Anything measuring 14 mm across is J250 or J300 and will not lock this tip.

Q: Which adapter fits a 1U-3352 tooth?
A: A J350 weld-on adapter nose, such as Cat's 6I-6354. The J350 nose is wider at the pin line than the J300 nose, so a J250 or J300 adapter will not carry it. Converting a bucket from J300 to J350 means replacing the adapters as well as the teeth — worth deciding before you order a pallet.

Q: Is 1U-3352 suitable for rock work?
A: Cat describes it as a general purpose tooth designed to penetrate and loosen soil and rocks, rated standard for wear and durability, for general excavation and loading at low to moderate impact and abrasion. For continuous rock or high-impact digging, the same 19 mm hardware is used with a heavier profile in the J350 family. Tell us the ground conditions and we quote the profile, not just the number.
