[Tow4]

Did you find out that M1008 alternator is the same size as 100type 27si? Actually i need new brush holder but I don’t know it is 100type or 200 type

Type 100 and 200 use the same brushholder.

Need to replace port side alternator. Gather from those in the know that direct replacement is Delco 27SI. What I did not know is there are two types 100 & 200. Type 200 being 100 amp and 100 being 80 amp.

Question for those in the know. Can I substitute 100 amp type 200 for type 100 80 amp on my M1009? Mechanic says dont need the amperage and will not create Charging sytem problem. Your input is important to me. Savings are huge stacking up the two types! DMLII sends....

Type 100 is used in military vehicles, type 200 in industrial

Type 100 and 200 use the same brushholder.

Different brush Assy. Look the same.

Keep in mind that many of the parts across the Delco SI series of alternators interchange. This is the correct part for 27SI type 100 series IR/EF alternators. It also fits Delco 10SI and 12SI alternators. You can find it by searching 39-101-3 on ebay.
