Expert Sourcing Alert: Are You Ordering K-Clutches (German) or C-Clutches (LZZF) for Your Basicpower Transmission?
Expert Sourcing Alert: Are You Ordering K-Clutches (German) or C-Clutches (LZZF) for Your Basicpower Transmission?
Introduction: A Costly Point of Confusion
One of the most critical errors in the global ZF parts market is assuming all “Basicpower” transmissions use the same clutch nomenclature. The German-designed ZF 4BP230 and the Liuzhou ZF (LZZF) Basicpower series use different naming conventions for their clutch packs, and the parts are not interchangeable.
As a 20-year technical specialist in both German and Chinese ZF systems, Tianjin XiaoHang Construction Machinery Co., Ltd. clarifies this vital distinction to protect your procurement accuracy.
Section 1: The German BP230 Standard (K-Clutches)
KV, KR, K1, K2, K3, K4
In the standard German 4BP230 (as seen in the 4681.084.018 parts catalog), the 6 clutches are designated by “K” (from the German Kupplung):
- KV (Forward)
- KR (Reverse)
- K1, K2, K3, K4 (Speed clutches) These clutches have specific part numbers (e.g., K1 Repair Kit 4681.298.014) and dimensions.
Section 2: The LZZF Basicpower Standard (C-Clutches)
CF, CG, CR, CA, CB, CC
In the Liuzhou-produced Basicpower (BP LZZF) transmissions, the 6 clutches are designated by “C”:
- CF, CG (Forward)
- CR (Reverse)
- CA, CB, CC (Speed clutches) These clutches often have different internal dimensions, such as smaller friction disc diameters (e.g., D128.0mm vs. D148.8mm).
Section 3: Why This Matters to You
Do Not Order a K1 Kit for a CF Clutch
A repair kit for a K1 clutch will not fit a shaft designed for a CA clutch. This is the most common reason for incorrect parts being shipped internationally. XiaoHang Machinery Co., Ltd. has the 20 years of repair and supply expertise to identify which system your transmission uses before we ship.
Conclusion: We Know the Difference
Stop guessing and avoid costly returns. Trust Tianjin XiaoHang Construction Machinery Co., Ltd. to verify your transmission’s BOM and supply the correct clutch components, whether it’s a K-series or C-series.
