Remarks Alternators 11AC Alter nator (External Regulator) Up To 1969 Reconditioning AC type alternators is becoming more difficult, due to the limited stocks of spare parts available. If you require a reconditioned unit, please contact Somerford Mini first to ensure we can help. Replacing an external regulator AC alternator with a more serviceable and powerful internal regulator ACR type is an option, but you should be confident of your electrical abilities if you intend to make the conversion. AC alternator fitted Minis are positive earth, and you will need to convert the system to negative earth to fit an ACR alternator. There is also a quantity of terminal conversion and rewiring required to connect an ACR alternator into the system. 1 GEU2201 ALTERNATOR, reconditioned, exchange 1 Not supplied with pulley and fan. 2 GGB501 BRUSH SET 1 3 27H8146 HEATSINK, with anode base diodes 1 4 17H8689 BEARING, rear 1 5 97H626 BEARING, front 1 6 37H6834 KIT, bearing retaining 1 7 27H3832 ‘O’ RING 1 8 37H2884 ROTOR 1 9 37H3096 STATOR 1 10 17H8695 SUNDRY PARTS KIT 1 11 13H2177 FAN 1 12 12G1054 PULLEY 1 13 FNZ207 NUT, pulley and fan securing 1 Included in sundry parts kit. 14 LWZ207 WASHER, locking 1 Included in sundry parts kit. 15 GEU250 PLUG KIT 1 Use if converting AC to ACR system. 16 13H8783 CONNECTOR, plug, small 1 Included in GEU250 plug kit. 17 ALU1003 CONNECTOR, plug, large 2 Included in GEU250 plug kit. 18 ADU4669 HOUSING, plug 1 Included in GEU250 plug kit. 19 ADU4670 COVER, plug 1 Included in GEU250 plug kit. 20 GCB10838 DRIVE BELT, alternator, water pump 1 Use with original 4 9/16" dia. and fan water pump pulley. 11AC Alternator Circuit Components 21 GEU6609 REGULATOR BOX, Lucas 4TR 1 22 GHF425 SCREW, self tapping, regulator attaching 2 23 BMK1092 CONTROL UNIT, warning light 1 24 PMZ408 SCREW, control unit attaching 1 25 LWZ204 WASHER, locking 1 26 FNZ104 NUT 1 27 BMK685 FIELD RELAY, alternator 1 28 PTZ1003 SCREW, self tapping, field relay attaching 2 16ACR and 17ACR Alter nator (Internal Regulator) 1969-80 Several different alternators w ere fitted in this period, of varying power rating (16 or 17ACR) and using two methods of sensing. Initially battery-sensed alternators were fitted; at unspecified times the designs changed to machine-sensed. The situation today as regards replacement alternators is that all ACR types (as far as Mini is concerned) supersede to a single, 17ACR, machine-sensed unit. If you have an early 1970s Mini and you suspect the alternator hasn’t been changed in the last 15 years or so, then you may well still have a battery-sensed alternator fitted. There should be no problem in exchanging it for a GXE2211 machine-sensed item. 29 GXE2211 ALTERNATOR, reconditioned, exchange 1 17ACR, machine-sensed; not supplied with pulle y, fan or capacitor. The following are parts specific to original Mini equipment ACR alternators. The Lucas identifying number should still be visible on the casing, and will usually be required when ordering parts. Batterysensed alternators were numbered 23748, 23750 or 23804;machine-sensed units w ere numbered 23640, 23725, 23774 or 23802. 30 NKC484A COVER, rear 1 31 GGB504 BRUSH SET 1 32 607693A BRUSH BOX 1 33 AAU8600 SURGE PROTECTOR 1 Not for 23640 alternator. 34 608074 CAPACITOR, suppression 1 For 23748, 23802, 23804 alternators. 35 18G8620 BEARING KIT, rear 1 36 18G8619 BEARING KIT, front 1 For 23748, 23750, 23802 and 23804 alternators. 518848 BEARING KIT, front 1 For 23640, 23725, 23774 alternators. 37 AAU2053 ROTOR 1 For 23640, 23750, 23804 alternators. 607691 ROTOR 1 For 23725, 23748, 23774 and 23802 alternators. 38 37H2250 SLIP RING 1 For 23640, 23750, 23804 alternators. 608423 SLIP RING 1 For 23725, 23748, 23774 and 23802 alternators. 39 606828 STATOR 1 For 23640, 23750, 23804 alternators. 37H6023 STATOR 1 For 23725, 23748, 23774 and 23802 alternators. 40 37H6924 RECTIFIER 1 For 23640 alternator. 90607688 RECTIFIER 1 For 23725, 23774, 23802 alternators.
