Zoomlion YZ rollers: drums, drive and engine identities

Read the roller suffix before matching its engine or drum

These Zoomlion entries cover different roller arrangements. The YZC12 rows include front and rear drums, while the YZ12 and heavier YZ machines have a drum-and-tire layout in the original specifications. A shared weight class does not make their running gear interchangeable.

The unexplained tire entry on the tandem machines is preserved as a rejected reference value; it is not a tire size to order.

Zoomlion's original road-roller catalogue separates mechanical single-drum machines, hydraulic single-drive machines and hydraulic dual-drive machines. Even similar YZ names appear in different schedules. Its YZ27 example uses a BF6M1013ECP, whereas the earlier reference here names BF6M1013C.

Keep those engine designations intact. The catalogue's vibration schedule also pairs different amplitudes with its two frequencies. A rounded inch entry that makes both amplitudes look alike hides that choice; it does not prove that both settings behave identically.

The catalogue arrangement is recorded separately below, without replacing the earlier model's figures.

Filter identification gives another useful distinction. WIX's Brazilian application catalogue names the YZC12 with the Deutz F6L912 and lists WL51820 for oil and WF33195 for fuel. Its YZ20E and YZ25 rows name BF6L913C and add the WA49783 air-filter reference.

Those rows support specific engine-and-machine combinations, not a filter kit for every YZ roller. The YZ18A uses a different engine and a different fuel-filter reference in the same catalogue. Losing the suffix can therefore send a parts search to the wrong row.

The WIX catalogue separates machine applications from broad engine listings and explains that a cross-reference alone does not establish an application. Photograph the installed engine identification and filter markings before using its historical references. A blank catalogue column is not proof that a machine has no filter in that circuit.

Nor does an entry for YZC12 automatically establish fit on YZC12A. The original comparison keeps those two models separate, including their different weights and static linear loads; confirm the installation instead of treating the final letter as decoration.
