Massey Ferguson MF-HEMA / MF #10 Tractor Hydraulic Gear Pump Replacement

Trace the correct reference

An enquiry for MF-HEMA / MF #10 should include the complete identifier, not a truncated family number. The corresponding Massey Ferguson hydraulic component must also be checked against the machine’s mounting arrangement.

No specific tractor serial ranges are established here for MF-HEMA / MF #10. Use the parts manual and existing hardware to complete the application check.

Technical specifications

Connection geometry and handedness

The selection should rule out the opposite drive hand at the outset: MF-HEMA / MF #10 is CW. Do not rotate a directional unit backwards to make its fittings line up.

The feed and discharge entries are NPT 3/8 and NPT 1/4. Establish whether each is a plain port, a thread or a connection requiring a separate sealing element.

How to compare pump sizes

The model is listed at 5.0 ml/rev, with a maximum pressure of 120 bar. The displacement gives geometric delivery per revolution; installed output depends on shaft speed and volumetric efficiency.

Within the comparison set, 527904M93 / MF #9 lists 6.0 ml/rev and 120 bar. That is a useful limit check for the MF-HEMA / MF #10 hydraulic request, not permission to alter the tractor’s original pump rating.

In addition to displacement, the table provides 5.0 L/min controlled flow. This is a separate selection datum and needs its own confirmation in the machine.

The stated speed is 3600 rpm. Before commissioning, verify the engine accessory drive ratio and that normal operating conditions do not exceed this listing.

Practical installation sequence

An installation review should include oil grade, tank venting and relief valve condition for MF-HEMA / MF #10. If the previous pump failed from starvation or high pressure, replacement alone will not remove the cause.

A repair should be assessed against the 120 bar pressure entry and the 3600 rpm operating-speed specification, not simply whether the pump produces movement.

Close relatives are not identical

The part Massey Ferguson 527904M93 / MF #9 is similar enough to deserve a check, not similar enough to presume interchangeability. Differences in CW/CW handedness or 6.0/5.0 displacement can affect both installation and operation.

Wrong-hand selection is a frequent avoidable risk when several variants share an external form.

What the sales engineer should receive

A useful request specifies MF-HEMA / MF #10 by OEM reference and includes the hydraulic system’s working duty. Supply the exact rotation convention and two views of the pump body.

If different pump types are required in one shipment, show quantities separately so the mixed-order arrangement can be priced correctly.

Before you approve a replacement

Does reference MF-HEMA guarantee that MF-HEMA / MF #10 fits?

No; the part number helps with identification, but the shaft, sealing face, ports and CW rotation need checking.

Why must the port sizes for MF-HEMA / MF #10 be measured?

The listed supply/discharge values (NPT 3/8 and NPT 1/4) do not describe the full gasket, thread seat or bolt pattern.

Ordering, samples and shipping terms

Order quantities are set according to pump type and total order value. A small order of 1–2 pieces can be considered at a higher unit price; new customers may request 1–5 samples when the item is suitable. Mixed-model orders are available, normally with a combined order value of approximately USD 1,500.

Typical production schedules are 10–25 working days for standard items, 20–45 working days for customized components, and 45–120 working days for project equipment. Usual delivery terms are EXW, FOB, CIF and DAP. FCA, CFR, CPT, CIP and DDP can be discussed for specific shipments. Confirm the final schedule and terms with the quotation.
