Lucas C45

This 12V Dynator unit replaces the Lucas C45 and is available with or without the rear mounted tachometer drive and for both negative and positive earth applications.

The standard Dynator has an output of 70A  and the units with tacho and rear drive have an output of 50A. They weigh approx 4.5kg, compared to 6.0kg originally. 

To ensure that the dynamo on your vehicle is a C45, it should be stamped with 'C45' on the case. If you cannot find this, check the distance between the mounting flanges, it should be approximately 166mm and the diameter of the body 4.5" (114mm).

• Diameter 4.5" (114mm)
• Internal mounting flange distance (Dim A) 166mm
• Shaft diameter 17mm
• 70A output (standard unit), 50A (tacho drive and rear drive)
• 4.5kg
• 3 year guarantee

As standard, units are supplied fitted with cooling fan and 63mm diameter pulley suitable for 10mm wide ('Z' section) belt. If a different pulley is required, then please enquire.

On the standard C45 the original pulley can also be used as the shaft diameter is 17mm. Please note that on the units with tacho drive and the power steering pump, the shaft diameter is 15mm. 

It should also be noted that a shorther version of the C45 is also available. (This is a much rarer unit and was only used by a few manufacturers in the late 50's and early 60's).

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.
