Caterpillar 3208 Plunger and Barrel | 6N7527 | Sleeve Metering 8mm

New aftermarket plunger and barrel assembly (part number 6N7527) for Caterpillar 3208, 3304, and 3306 sleeve-metering diesel fuel systems. This is the precision-matched pumping element that meters and pressurizes fuel in CAT's sleeve-metering injection pump. Manufactured by FP Diesel — a new replacement part, not remanufactured.

Key Features:

• New aftermarket plunger and barrel assembly, part number 6N7527 (FP Diesel FP-6N7527)
• Precision-lapped matched pumping element for CAT sleeve-metering fuel systems
• Fits Caterpillar 3208, 3304, and 3306 engines and related industrial and gen-set applications
• 8mm plunger, naturally-aspirated (NA) metering configuration
• Restores OE-spec fuel metering and delivery

Specifications:

• Base part number: 6N7527 (FP Diesel FP-6N7527; Caterpillar format 6N-7527)
• Component type: Fuel injection plunger and barrel assembly (sleeve-metering)
• Plunger configuration: 8mm, NA metering

• Engine make: Caterpillar
• Engine models: 3208, 3304, 3306, D330C, D333C, SR4

Compatibility / Fitment:

• Fits Caterpillar 3208, 3304, and 3306 sleeve-metering diesel engines
• Also referenced for D330C and D333C industrial engines and SR4 generator sets
• This is the 8mm NA metering configuration — plunger diameter and metering must match your fuel system
• Sleeve-metering plunger & barrels are calibration-specific — confirm your CAT part number, engine output, and serial before ordering
• One plunger & barrel per cylinder (a 3208 V8 uses eight; a 3306 uses six; a 3304 uses four)

Conclusion:

The FP Diesel 6N7527 is a new aftermarket plunger and barrel assembly for Caterpillar 3208, 3304, and 3306 sleeve-metering fuel systems.
