View Full Description

This 12V Dynator unit replaces the Lucas C48 and is available for both negative and positive earth applications. It has an output of 65A compared to 30A of the original and weighs 5.9kg, compared to 8.5kg originally. The C48 is a fairly rare unit and was fitted to a few larger cars such as Roll Royces and Bentleys.

To ensure that the dynamo on your vehicle is a C48, it should be stamped with 'C48' on the case. If you cannot find this, check the distance between the mounting flanges, it should be approximately 203mm and the diameter of the body 4.8" (122mm).

  • Diameter 4.8" (122mm)
  • Internal mounting flange distance (Dim A) 203mm
  • Shaft diameter 15mm
  • 65A output
  • 5.9Kg

As standard, two pulley options are available.

  • 82mm diameter double V pulley (LMP023) suitable for 10mm wide ('Z' section) belts.
  • 73mm diameter double V pulley (LMP164) suitable for 16mm wide ('B' section) belts

If a different pulley is required, then please enquire. Alternatively, use your original pulley on the new unit as the shaft sizes are the same.

Electrical connection to the vehicle is easy and straight forward using the original dynamo control box as a junction box. Fitting instructions are given in the downloads section below (one for negative earth installations, the other for positive earth). Alternatively, the original voltage control box can be removed and replaced with a fused dummy control box, which can be used as a suitable junction box to easily connect the Dyantor to the vehicles wiring.
