Alternator JFZ2760 28V 75A 10PK Deutz SDLG

Product Attributes

Product Details

Product Overview

The JFZ2760 is a Deutz OE-spec replacement alternator delivering 28V output at 75A with a 10-rib (10PK) pulley, engineered for Deutz diesel engines as fitted to the SDLG LG956L wheel loader. This remanufactured (renovated) aftermarket unit, identified by the 3701010-687 and JFZ2980DC1J cross numbers, matches the original 28-volt charging-system specification of these heavy-duty construction platforms.

Fitted with internal regulator design, this alternator is stocked in-house with a 1-year warranty and 10-day dispatch lead-time. The 75-amp rating supports the standard electrical load of these loaders, including lighting, instrumentation, climate control, powered accessories and battery charging.

Key physical specs: net weight 6.5 kg, gross weight 6.9 kg, overall dimensions 260 x 260 x 210 mm, supplied inside neutral kraft inner carton.

The Deutz / SDLG LG956L Platform and 28V 75A Charging System

Deutz diesel engines power a wide range of construction machinery, including the SDLG (Shandong Lingong) LG956L wheel loader. These machines use a 24-volt electrical system with a 28V charging output. The 75A alternator supports standard equipment including lighting, instrumentation, climate control, powered accessories and battery charging across shift-long operation.

This unit is specified as 28V 75A, matching the factory charging-system specification of these platforms. The 10PK multi-rib pulley matches the original accessory-belt layout. Installing a pulley with the wrong rib count will cause belt mis-tracking, slippage, premature belt wear and charging faults. Always cross-check against your old alternator before ordering.

Technical Specifications

Engine Compatibility and Cross Reference

This alternator fits the following applications. Do not rely solely on the application name for fitment validation; always verify engine code, production year, old-part OE number, pulley type and amp label on your original alternator.

Multiple Deutz and Chinese alternator OE numbers appear across production batches and regional specifications for this same alternator family. If your original unit bears one of the listed cross-reference numbers, JFZ2760 serves as a direct drop-in replacement.

What to Look for in a Replacement

Follow these five verification steps before placing your order to avoid wrong-part returns:

• 1. Confirm the system voltage: this is a 28V-output alternator for heavy-duty 24V systems. Never fit it to a 12V passenger car system.

• 2. Check the amperage label on your old alternator: confirm it is rated for 75A. Different amp ratings are not interchangeable.

• 3. Count pulley ribs: this unit requires 10PK. Units with a different rib count are incompatible for this accessory drive setup.

• 4. Confirm the exact Deutz engine code and machine model (LG956L etc.), and match OE / reference part numbers stamped on your original housing.

• 5. Weight cross-check: genuine matching unit weighs approximately 6.5 kg net; significant weight difference indicates wrong assembly.

Application Scenarios

• Independent repair shops and construction equipment specialists servicing Deutz-powered loaders across China, Asia-Pacific, the Middle East, Africa, Europe and Latin-America.

• Mine and quarry maintenance teams servicing SDLG and similar wheel loaders.

• Fleet workshops maintaining loader fleets with Deutz engines.

• Parts counters and jobbers stocking Chinese construction machinery charging-system components.

• Used-equipment export traders supplying pre-owned loaders to global secondary markets.

FAQ

Q: Which machines does this alternator fit?
A: It fits Deutz diesel engine applications including the SDLG LG956L wheel loader. Always verify against the OE number, pulley and mounting layout of your original alternator before ordering.

Q: Is this alternator brand new?
A: No. This unit is a remanufactured (renovated) alternator, professionally rebuilt and tested to restore original performance. It is not a brand-new unit.

Q: Is this alternator 28V or 24V?
A: The unit delivers 28V charging output, matching heavy-duty 24-volt system standards. Do not fit it to a 12V passenger car system.

Q: My old alternator shows OE number 3701010-687 or JFZ2980DC1J, will JFZ2760 work?
A: Yes. These numbers belong to the same alternator family. It serves as a direct replacement.

Q: What is your warranty and lead-time?
A: Goods are in stock with a 10-day dispatch lead-time. A 1-year warranty applies from installation date; warranty excludes damage caused by mis-installation, wrong belt tension, or vehicle-wiring faults.

In Practice

For technicians working on Deutz-powered construction equipment: Before removing the existing alternator, perform charging-system diagnostics. Measure battery terminal running voltage with a multimeter: on a 24V system expect around 27.6-28.8V when charging. Weak batteries, corroded ground connections or a faulty main harness can mimic alternator failure symptoms. Always disconnect the battery negative terminal before commencing removal work.

Take photos of wiring connectors and bolt positions during disassembly to avoid mis-routing during reassembly. Confirm the 10PK belt is correctly seated in all pulley grooves and observe correct belt tension: 10-15 mm deflection when pressing the belt mid-span. Over-tightened belts accelerate alternator bearing wear; loose tension creates slipping and insufficient charging. Torque mounting bolts to Deutz / SDLG workshop-manual specifications.

Inexperienced mechanics are recommended to entrust replacement work to a qualified auto-electric repair shop. Incorrect wiring risks burning the alternator or machine electrical components.
