Part number 4120001019, model CBW57F100R, is a single hydraulic gear pump listed in our catalogue for the body lift circuit of LGMG MT60 and MT86 mining dump trucks. Olive Branch Hydraulics manufactures it in Xinji, Hebei, China, under SKU OBH-MN-074.
This is an aftermarket replacement pump manufactured by Olive Branch Hydraulics.
The MT60 and MT86 references are catalogue fitment references, not a universal fit. Before quoting, we confirm the hoist circuit and the truck serial number for each order.
Compare the shaft, flange and port positions against the old unit; the product photograph alone does not confirm fitment.
The model code alone does not confirm a fit. We do not derive displacement, rotation or tooth count from "CBW57F100R," ; verify these against the original pump specification.
These four checks decide whether this pump matches your truck:
| Check Item | Status in Our Catalogue | What to Send Us |
|---|---|---|
| Truck model and serial number | MT60 / MT86 catalogue references | Nameplate photo with the full serial number |
| Circuit function | Body lift (hoist) circuit | Confirmation that the pump feeds the hoist and not steering |
| Shaft rotation and spline | Confirmed per order | Rotation viewed from the shaft end, plus a shaft photo |
| Flange and ports | Square flange, four holes, side ports | Flange and port measurements or old-pump photos |
Some suppliers list a shaft tooth count for this number. That figure has not been validated for our pump, so verify the spline on your old unit.
You buy directly from the manufacturer, for sample- and drawing-based configuration matching. Pricing is quoted EXW Xinji, Hebei, and you choose the freight forwarder.
Inspection points and required documents for your order are confirmed before production.
No. The same number appears online for an unrelated SDLG shift control assembly. Our 4120001019 is the CBW57F100R body lift gear pump only.
Not automatically. MT60 and MT86 are catalogue references, so we confirm the circuit and the truck serial number before quoting.
Not without verification. We treat it as equivalent only after comparing shaft, flange, ports and rotation.
Rotation is confirmed per order and is not taken from the model code. Tell us the rotation viewed from the shaft end, or send the old pump.
Yes. Samples are built against your confirmed configuration, and the sample cost and timing are listed on the quotation.
For a manufacturer EXW quote, use the inquiry form. Send the part number, the truck model and serial number, the quantity and photos of the old pump. We will reply with a configuration check, a price and the sample and delivery terms.
