85 E350 Super 100A alternator internal parts list.

[Orkea6]

Hey Guys,

I am looking for the part number for the drive bearing on a 100A Alternator - Motorcraft OEM GL-286-RM - I am lost in the catalog, I find the calibration list is 390 for this truck- but there must be elsewhere to look.

Can anyone help me get a number for item 10094 in the exploded view on the 100A Motorcraft unit or better yet- point me to where I can look it up?

The story

My "newly rebuilt" 100A alternator has had the bearing fail *again* - I had upgraded to 100A unit in 2006 and it last until mid 2020- about 45K miles when it seized up. As this is a motorhome and I was a few hundred miles from home, I replaced the unit with a rebuilt Carquest brand alternator- it lasted less than 100 miles and seized up as well. I replaced that one and all was well for about 2,000 miles, now this too, has seized up. These belts need to be pretty taught in order to not squeal (they still will at first start)- but this is getting ridiculous because in order to change the alternator on the E350, I must remove the radiator (because silly me, I put a thicker radiator in the truck and the pivot bolt is now too long to come out otherwise.

Any help would be greatly appreciated. I thought I got the right bearing part- but what I have is the bearing for a 60A alternator. I hate buying another rebuilt- and though Advanced Auto *might* give me a third unit- they are ALL getting the same chineseium bearings which will not last.

Thanks

Looks like 10094 is the bearing? If so:

So that makes it C9ZZ-10094-AA "*GE-21"

FYI with a little more Googling, no promises this is the right part, but it looks like PFI makes an interchange for this:

If that's right, their part number 6203-2RS-C3 gives me this spec sheet:

http://bearingsize.info/catalogue-online/deep-groove-ball-bearings/bearing-6203-2rs-c3-pfi-obj175758.html

So that's a 17mm bore 40mm OD 12mm width deep groove sealed ball bearing. Maybe that'll let you find some alternatives to try, PFI or otherwise.

I must be missing something (it happened before) - where did you find the part list for the alternator?

Appreciate the help (and patience).

I'm pretty sure the Ford p/n for your 100A alternator is E1UF-10300-AA.

My master parts catalog is on CD so unfortunately I have no way to access it from my phone but the drive bearing for those alternators is 62034 (2RS)

This bearing is 17 x 40 x 12mm with seals on both sides.

There's no need to buy one from a specialist alternator parts supplier or through a Ford dealer.

You can find quality name brand bearings like SKF or Timken for as low as $2.95 online.

Hope this helps

Beat me to the checkers! 😂

Thanks for your very helpful post

Thanks Guys- yes, it seems the 6203-RS is the ticket. I found that I have some GM branded (on the box) ACD# 19312054 - and the part in the bag says 6203-RS right on it- but the specs shows it is 17mm wide, rather than 12mm - and now that I have it in hand, it is actually 12mm width... china strikes again. +/- 5 mm- who would notice once assembled?

You guys rock!

I must be missing something (it happened before) - where did you find the part list for the alternator?

This is from the master parts catalog (MPC), which you need in order to get the prefix and engineering suffix to complete the part number from the basic part number shown in the illustration.

Additionally, note the number with an asterisk just below the Ford part number is the Motorcraft p/n (GE-21in this case)

This often becomes handy when you want an OEM part like a switch or sender from a local parts store that doesn't have access to the dealer network.

I don't remember where I found these links originally - Googling, a post here, or something like that. I was fairly sure it was here but I could be mis-remembering. In any event they're invaluable. The illustrations provide MUCH better parts diagrams than the shop manuals although it can definitely be daunting to go through them! Once you find the diagram for your exact component you take the number of the part you need and that's the "group number." You search for THAT in the bigger 3490-page beastie and then find the closest fit to your year, model, etc.

Somebody correct me if I'm explaining something wrong...

Your explanation of how the MPC works is spot on!

I'm pretty sure Gary's copy of the MPC has been OCR'd to make it easily searchable rather than having to develop a sense of how those catalogs were originally organized.

Back in the days of paper a good counterman could crack that big binder and have you a part number in seconds, but those days are mostly long gone.
