ELECTRICAL REBUILDER’S ASSOCIATION — Technical Document SS201508B www.electricalrebuilders.org AVOID SOMT CONFUSION sre Lou often field calls from fellow rebuilders pertaining to the commutator (see Figures 1 and 2). The chart also provides the Delco Remy Type 400 50MT starter. Most of the issues OE Delco armature number for each voltage application. You are related specifically to 32 and 64 volt applications. In can accurately cross reference a Delco armature number to most cases, the cause of the problem turns out to be your designated supplier part number to insure you get a incorrect or mismatched component parts. You would think that correct match. the most common part to get wrong would be the solenoid. But on It can be very difficult to properly test one of these higher the contrary, it seems that the armature and field coils actually voltage starters in your shop and know for sure from a free spin cause more problems for rebuilders. test that it will work properly when installed. The correct Armature bar count is extremely important when identifying armature and field coils are very important to obtain the correct armatures for these two application voltages. I have researched rotation and torque/power. If you mismatch either one along and put together a reference chart that includes some of the more with an incorrect solenoid it will wreak havoc with your rebuilt popular 50MT part starter numbers along with voltage, armature, unit. bar count, direction of rotation and field coils. You can quickly see the difference between a 25 bar commutator and a 35 bar 1951254 1945853 Long Shaft An ERA Publication. ©2015, Electrical Rebuilder’s Association. All rights reserved.
