These drawings are of an alternator mount for a Ford Pinto engine. It is meant to be used with a Lucas 17ACR alternator as fitted to the Cortina, Capri, Austin Mini, Austin/Rover Metro etc. This is a cheap and compact alternator with more than enough power for a Locost. The alternator is supplied in two versions. With one version the belt tension adjuster is in the wrong place but it can be moved my removing the rear cover, undoing the bolts that go right through the body and rotating the front aluminium housing.

The drawings have been based on a 2L Sierra engine with two drive belts and show two different positions for the mounting holes. With the front pulley used there is very little clearance between the alternator and the chassis. With the rear pulley used the belt tensioner can foul the heater pipe. I have allowed for both on my bracket as I am not sure what position I will use yet.

The bracket bolts onto the lower two mounting holes on the block. The upper front mounting hole has to be cut away to allow the alternator to be moved closer to the engine.

If your engine uses a single belt then make the body to the front pulley dimensions. Fit the brace but not the two uprights.

Bolt the uprights to the alternator - they both fit behind the alternator's legs. Bolt the bracket body to the engine and hold the alternator in place, with a belt around the pulleys. When you have the alternator's pulley in line with the engine pulleys tack weld the uprights on to the bracket body. Recheck the pulley alignment and then fully weld the uprights. This is the way I made my bracket, the dimensions were measured afterwards.

If your engine uses a single pulley could you please let me know how far the front upright is from the back of the bracket and I will update my drawings.
