Marbed 9502 – Rack Travel Dial Gauge Holder for Bosch PE/P Pumps (OEM Ref. Bosch 1 688 130 030, EFEP 393)

The Marbed 9502 comparator holder is a professional workshop tool for surveying the rack stroke in Bosch PE/P inline fuel injection pumps.

• Mounting: threaded 24×1.5 mm, with 18 mm protrusion into the pump body.

• Measurement: direct reading — the dial gauge probe contacts the rack directly, no lever system required.

• Clamp: supplied with clamp and rods (art. 9502-A) to secure the dial gauge.

• Extensions: can be completed with adapters for other pump series:

  • 9502-C: reduction for Bosch 8500 pumps (threaded 24×1.5 mm inside).

  • 9483-K19: reduction for Bosch MW pumps (thread 26×1.5 mm outside).

This makes the 9502 a versatile, precise, and durable tool for calibration and maintenance in diesel workshops.
