Convert IH 574 from Lucas to NA Alternator

Avondale · Nov 18, 2011

Can anyone tell me which model of NA (i.e AC Delco) alternator would fit the IH 574? I have a Lucas on it now and am considering a winter project to completely re-wire and modernize the beast. Currently, only batt and starter works and all wiring has been "messed" with by previous owner(s). Many wires to no where, etc. Snake's wedding inside panels and there are no lights fitted. Would like to run head, tail and work lights as well as some aux power circuits (trailer, etc). Thanks in advance for any info. PS: I have searched the Case IH forums.

Since it is a Lucas alternator, I'm assuming your tractor is a European model. Here is a link to Case/IH. Do a parts search for the 574, but select the North American model. About all I saw listed for the N.A models, were Delco units.

Thanks, I'll look into your suggestion further. May just need model number and shop at auto-recycler.
