Massey Ferguson 3533911M91 / 14 cc Tractor Hydraulic Gear Pump Replacement

Start with the removed pump

An enquiry for 3533911M91 / 14 cc 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 3533911M91 / 14 cc. Use the parts manual and existing hardware to complete the application check.

Technical specifications

Compared with a neighboring listing

Consider Massey Ferguson 7228132 / 20 cc only as a reference to compare: it is designated CW and has 20 ml/rev. 3533911M91 / 14 cc is designated CCW, so any departure in direction or shaft style must be resolved.

Do not infer a warranty of interchangeability from an OEM number appearing in a search list.

Interpreting the pressure listing

3533911M91 / 14 cc carries a 14 ml/rev displacement entry. This is not a stand-alone guarantee of a required lift speed; the working rpm and load-dependent losses remain system-specific.

Within the comparison set, 7228132 / 20 cc lists 20 ml/rev and 200 bar. That is a useful limit check for the 3533911M91 / 14 cc hydraulic request, not permission to alter the tractor’s original pump rating.

No controlled-flow rate is specified for this item; please include duty conditions if that value is required in the RFQ.

The stated speed is 500–3000 rpm. Before commissioning, verify the engine accessory drive ratio and that normal operating conditions do not exceed this listing.

Inspect the hydraulic drive

Use the dismantling photographs to place 3533911M91 / 14 cc at the same mounting angle as the original. Verify that hoses reach naturally and that no connection has been cross-threaded or over-tightened.

Make the clockwise/counterclockwise check explicit in the workshop instruction: 3533911M91 / 14 cc is CCW.

Shaft-end direction and port layout

One of the first installation checks is direction: this reference is CCW. Also check that the pump body can be seated without stressing the hoses.

For hose matching, write down both port specifications: feed Ø19, discharge Ø14. Thread class and sealing face matter as much as nominal size.

Complete the pump identification

Include the part 3533911M91, the delivery destination and any customization needs. Attach the removed pump’s outline dimensions rather than depending on an estimated scale from the catalogue image.

Let the quotation identify any uncertainties in compatibility before manufacturing begins.

Common selection questions

Is the Massey Ferguson tractor name sufficient for ordering?

No. Confirm the exact pump removed from the tractor, its drive-side rotation and its connection geometry.

What does the 250 bar pressure value represent?

It is the maximum catalogue entry for this model, not proof that the tractor circuit or hoses may safely operate at that pressure.

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.
