8991 A/C Compressor for Caterpillar PS300C

Sanden 8991 SD7H13 A/C Compressor for Caterpillar PS300C

Sanden 8991 is positioned as a complete aftermarket replacement for PS300C service demand, with its 12V clutch providing an immediate screening point for buyers. This complete air conditioning compressor is specified for Caterpillar PS300C equipment under reference 8991. Its SD7H13 configuration combines a 12V clutch with a two-groove 125 mm pulley for R134a systems. The product is intended for distributors and equipment service suppliers that need a clearly identified replacement assembly rather than a clutch, coil or other compressor component.

Reference 8991 is the first number to use when requesting a quotation. The electrical rating, pulley layout and rear connection arrangement should then be compared with the removed unit. That sequence helps buyers avoid approving a visually similar SD7H13 compressor that belongs to another machine or belt configuration.

Sanden 8991 Compressor Specifications for Purchasing

Why the 12V A2 Configuration Matters on Caterpillar PS300C for the 8991 A/C Compressor

PS300C owners often purchase through an equipment dealer, an independent A/C workshop or a general construction-parts importer. Each buyer may describe the same requirement differently: by machine model, by the number 8991 or by the SD7H13 body. Keeping those identifiers together on the inquiry makes the order easier to interpret and gives the supplier a better basis for checking the physical configuration.

The 12V coil is a critical checkpoint because many construction compressors use 24V electrical systems. The two-groove 125 mm pulley is another visible feature that should be confirmed before dispatch. Neither point should be inferred from the compressor family alone; SD7H13 units are sold with several clutch, head and mounting variations.

Sanden 8991 A/C Compressor Original-Unit Checks Before Quotation

1. Read the original label and confirm reference 8991 where available.
2. Check that the machine clutch circuit is 12V.
3. Confirm the A2 two-groove pulley and measure the original pulley against the 125 mm specified value.
4. Compare the ear-mount pattern and the position of every mounting point.
5. Check the horizontal O-ring suction and discharge connections, including their orientation and spacing.
6. Compare the electrical connector and wire position before approving the order.

A nameplate photo is useful, but it is not sufficient by itself. For difficult matches, send a front pulley view, a rear head view and a side view that shows the mounting ears. The combination helps identify differences that may be hidden when only one product angle is supplied.

Sanden 8991 A/C Compressor Supply for Equipment Dealers and Importers

Elecdura supplies the 8991 compressor for wholesale and replacement programs serving construction equipment. Orders can be arranged with neutral packaging or an agreed private-label presentation. Buyer item numbers, the 8991 reference and Caterpillar PS300C application wording can be added to the label specification to support warehouse identification.

For importers building a wider mobile A/C range, this 12V two-groove unit can be planned alongside other heavy-duty compressors, subject to order quantity and production scheduling. Mixed purchasing should still retain a separate carton identity for every compressor configuration; a generic “7H13 compressor” label is not precise enough for stock control.

Sanden 8991 A/C Compressor Receiving and Service-Readiness Checks

On arrival, verify reference 8991, the 12V connector, A2 125 mm pulley, ear-mount body and horizontal O-ring ports before the compressor enters stock. Keep the ports sealed and separate any unit with freight damage or a configuration that does not match the purchase order.

SP10 and a 135 ml compressor fill reference support product identification and service planning. The workshop should use the applicable Caterpillar information for the complete system and account for oil retained elsewhere; the product reference is not a universal instruction to add a full charge to every repair.

Sanden 8991 A/C Compressor Commercial Terms for PS300C Service Networks

The 8991 compressor can be quoted for dealer, importer and service-network demand with a standard MOQ of 50–100 pcs, an indicative 7–15 day lead time after confirmation and an 18-month warranty under agreed terms. Neutral cartons and OEM-label or ODM requirements can be reviewed for qualified orders. Because this unit is a 12V A2 125 mm configuration, its carton and packing-list identity should remain separate from the more common 24V construction-compressor lines.

Sanden 8991 A/C Compressor Buyer FAQ

Why is the 12V clutch a critical check for compressor 8991?

Construction-equipment compressor ranges commonly contain 24V units, while Sanden 8991 is specified as a 12V SD7H13 assembly. Read the electrical marking on the removed compressor and verify the machine clutch circuit before ordering. A similar housing or Caterpillar application does not override voltage. Recording 12V on the RFQ, purchase order and receiving label gives each team the same first rejection point for a wrong version.

How do I confirm the A2 125 mm pulley on the removed compressor?

Use a square front photograph to confirm two A-type grooves, then compare the 125 mm diameter, belt position and clutch offset. A single side image can hide the second groove or make the diameter difficult to judge. Pair the visual check with reference 8991 and the 12V connector so the supplier is not asked to identify the unit from the SD7H13 family name alone.

How should Caterpillar PS300C application data be used for Sanden 8991 A/C Compressor?

Caterpillar PS300C is the stated application for Sanden 8991, but the machine name alone should not be treated as a universal fitment guarantee. Confirm the original label, 12V clutch, A2 125 mm pulley, ear-mount body and horizontal O-ring connections. Add the machine serial range or service record when available so the quotation can compare the installed unit with the specified SD7H13 configuration.

What should be compared on the ear mount and horizontal O-ring head for the 8991 A/C Compressor?

Photograph every mounting ear from the side and mounting-face directions, then show both suction and discharge connections square to the camera. The bolt positions, ear spacing and horizontal O-ring orientation must agree with the compressor being replaced. These features are more decisive than the general 7H13 body shape, because another SD7H13 unit may use a different mount or rear head even when its clutch appears similar.

How should the SP10 135 ml reference be used for the 8991 A/C Compressor?

SP10 and 135 ml identify the lubricant and compressor fill reference for the 8991 configuration; they are not a blanket instruction to add a full charge to every vehicle system. The technician should consider oil retained in hoses and other components and use the applicable Caterpillar service information. The reference supports product identification, while the final system balance depends on the actual repaired circuit.

What should a distributor send for an 8991 A/C Compressor quotation?

Send reference 8991, Caterpillar PS300C, required quantity, destination and desired neutral or branded packaging. Include label, pulley-face, mounting-side, rear-head and connector photographs from the removed compressor. State whether the machine has been modified or previously converted. Elecdura can then quote the specified 12V A2 125 mm complete assembly as a distinct item rather than a generic Caterpillar SD7H13 compressor.

Send a Product-Specific RFQ for Sanden 8991 A/C Compressor

Include quantity, destination, required delivery date and packaging preference. State Caterpillar PS300C and reference 8991, then attach original-unit photos whenever possible. Elecdura will confirm the requested 12V, A2 125 mm SD7H13 configuration before preparing the wholesale quotation.
