Though this is on the parts list 91004-MT3-003, I don't understand what it does. Does it aid in assembling the 28A to the 40A somehow, or can it be skipped since I'm getting a refurbished alternator from Ken Heming.
You are quickly becoming folk legend in the alternator forumsDo you get only the genny, or also the "drive" (the part sitting in the engine case)?
Your bearing is loc #35 in the fice:

Thanks for the clarification. I recently went through quite a challenge understanding what was needed for the upgrade. Reason, rcb just upgraded and described the process as plug and play, so naturally I was perplexed. Why was it so easy and he didn't remember having to get the before mentioned bearing, I thought, "Why not, it's on the list?"The assembly that plugs into the engine case and has the split gears that engage the flywheel is usually called the Alternator Shaft Assembly; both the 28amp and 40amp versions. Upgrading to the 40amp requires assembling that version's Alt Shaft Assy with three 40amper parts (base plate, shaft, and the bearing you asked about) and the other parts (common to both versions) transferring from the old 28amper's Alt Shaft Assy.
Martin points out that if you're using salvage parts: get the whole 40amper's Alt Shaft Assy. Can't imagine any breaker/salvage yard disassembling the Alt Shaft Assy to sell you just the 3 needed for an upgrade. Nobody needs the other parts of it separately. Offer 1/2 of the online price for the three parts new and ask for the whole thing. Recommend you get a new o-ring for the baseplate-to-engine seal, and the one for the Alternator-to-base plate seal.
Also, if you are going the salvage route, get the '96-'02 fuseblock and its wiring harness (to starter-relay/main-fuse and battery).

Whenever you manipulate, or pressing/hammering/jiggling a shaft in/out its recommended, suggested to replace the bearing in question...The problem wasn't the cost of the bearing...
JuST to be clear, the bearing in question (item 13 in the schematic) has already been installed on the 40amper's shaft in the picture l linked above.I'd like to thank you for the photos from the link below. It's what started the question about the difference between the base plate I thought I needed compared to the base plate assembly.
Thanks. So if I'm splitting the 28A base plate assembly option, and ordering the shaft and 40A base plate, I do need the bearing?JuST to be clear, the bearing in question (item 13 in the schematic) has already been installed on the 40amper's shaft in the picture l linked above.
Short answer: Yes. It's not one of the parts common to both versions that can be transferred.Thanks. So if I'm splitting the 28A [Alternator Shaft Assembly] option, and ordering the shaft and 40A base plate, I do need the bearing?
I'm ok with the short answer. Placing the alternator this time, will be the 3rd time in 3 weeks. Wanna do it right.Short answer: Yes. It's not one of the parts common to both versions that can be transferred.
