| Lucas ACR High Output Replacement Alternator
Lucas ACR Replacement Alternator - available with 36amp, 45amp, 65amp or 80amp output
This alternator replaces the standard Lucas alternator fitted to most English vehicles from 1960s onwards. These units are direct replacements complete with fan and pulleys and will not require any modification to the vehicle. However note that these units are a direct swap only for existing Lucas units, they are not a direct swap for Bosch or Denso units as the attachment brackets will be different.
These units are new outright, not reconditioned and individually hand tested here in East Sussex.
Lucas alternators were produced in 2 versions - Left Hand Fitting and Right Hand Fitting
Right Hand Fitting (ie the attatchment bracket is on the right-hand of the alternator when you are looking at the front pulley wheel) eg Mini, MG Midget, MGB (4 cylinder), Land Rover Series II/III, Lotus Elan, Lotus Elite, Lotus Eclat, Triumph Spitfire, Triumph GT6, Triumph TR5/6, Triumph Stag, Jaguar E-Type, XJ6 to 1981, Ford Crossflow, Jensen Healey, Morgan 4/4 etc
Left Hand Fitting (ie the attatchment bracket is on the left-hand of the alternator when you are looking at the front pulley wheel) eg Ford Pinto, Ford V6, Ford Escort RS2000, MGB V8, Triumph TR7 etc
If you order the wrong hand then its very easy to convert a left-hand unit to a right hand unit and vice versa:
1) Loosen the 3 bolts that hold the casing on (the casing is just a cover, its not sprung - nothing will jump out)
2) Turn the body around (there are only 2 possible positions, left or right hand) while holding the plastic end cap (the plastic end cap must not rotate)
3) Retorque the casing bolts
Dimensions: Internal distance between mounting lug holes 88mm, external distance between mounting holes 108mm, (lug width 10mm each), adjusting mount lug width 10mm, pitch circle diameter between mounting and adjusting lugs 145mm, mounting bolt hole size 8mm, distance centre of mounting bolt to centre of pulley 91mm, pulley diameter 62mm, pulley groove 10mm (alternative non-standard pulleys available on request), weight 4kg - 5.5kg (depending on output). All measurements approximate.
What output size do we recommend for your vehicle? When vehicle manufacturers were gradually moving to alternator fitments (rather than dynamos) in the 1960s then 28amp was a common fitment. Moving into the 1970s when cars were more likely to be fitted with increased creature comforts such as more powerful heaters, two speed wipers, better lights then a 36amp and later a 45amp was a more common fitment. There is no disadvantage in having a more powerful alternator than you think you may need (apart from the initial cost), due to internal regulation your battery wont be overcharged it will just re-charge quicker and drain less, and allowing peace-of-mind for restarts if you had previously been driving with heater, wipers, lights etc all on at once.
Are the chrome plated bodies concours quality chroming? No, not at this price - nice and shiny and a thing of beauty but not councours winning. In fact in our experience few chrome plated componments are absolute concours quality straight quality out of the box, especially not ones designed to fit under the bonnet. If you need concours quality chroming then we use and recommend the London Chroming Company.
