Экскаваторын шүд болон ачигчийн зүсэгч ирийг адаптерийн системээр хэрхэн сонгох
This article explains bucket tooth and cutting edge selection for excavators and wheel loaders. The 1U3202 tooth belongs to the CAT-style J200 system and is typically used with a 119-3204 adapter, 8E6208 pin and 8E6209 retainer on CAT 320-class excavators. ZL50-class 5-ton loaders use bolt-on or pin-type teeth and cutting edges where buyers must check edge thickness, bolt specification, center tooth and side tooth positions, and compatible loader model. The guide compares standard, rock, tiger and twin-tiger profiles, and warns that mixing tooth, adapter and retainer geometries from different brands causes looseness, lost teeth and adapter nose cracking. Buyers should send machine model, old part number, adapter photo and pin-hole dimensions.
Many buyers send “I need ZL50 teeth”, but ZL50 is a loader platform, not one tooth type. On the other side, 1U3202 is not a universal tooth — it is a CAT-style J200 standard tooth. The things you must check are completely different.
A J200 base is often about 89 mm wide × 67 mm high with a 41 mm pin hole, but final fitment depends on the stamping on the bucket adapter nose.
For ZL50, ZL50G, ZL50GN, CLG856, LG956 and similar 5-ton loaders, the front end usually is not a J-series tooth system. It normally includes:
Cutting edge thickness often around 33.5 mm, but this varies by brand.
Common numbers include 252101813 / 252101811 / 252101812 for XCMG/SDLG-type loaders, and 72A0005 for LiuGong 5-ton-class machines. These numbers are not cross-brand interchangeable.
Adapter taper, pin groove and retainer shape differ between manufacturers. Forcing Brand A teeth onto Brand B adapters may seem fine at installation, but leads to:
Rule of thumb: buy tooth, adapter, pin and retainer as one system. If the adapter nose is badly worn, do not just swap tips — repair, re-weld or replace the lip/adapters.
1. Machine brand + model（CAT 320D / PC200 / ZL50G / CLG856…）
2. Old tooth number（1U3202, 252101813, 72A0005…）
3. Adapter photo + nose stamping
4. Pin-hole diameter and pin direction（vertical / horizontal / rubber lock）
5. Cutting edge thickness, bolt spec, center/side tooth layout
