What are these inside "NOS" cluster gear?
Picked up what was supposed to be a NOS cluster gear but it's definitely not new and had these odd sleeves in the bore that had to be pressed out. I don't have that much history w/ Model As but all I've ever seen are two roller bearings and a spacer. Anyone recognize these?

If large enough, those look to be for the post war common jeep T 90 tranny.

I'd politely suggest doing more home work before bashing away at something.
Earlier cluster gear used a two bearings and a sleeve. Later gears used those two collars to locate the bearings. replacing the pipe sleeve. It is OK to ask questions, this was new to all of us at one time. |

Re: What are these inside "NOS" cluster gear?
That cluster is all straight cut gears so it is an old one. I just can't say if it's model A unless a person has a tooth count for all the gears. The tooth count is 31 24 18 15 for the A7113 cluster. The B7113 cluster has two helical gears since they went to a semi-synchronized transmission in 1932. 4-speeds had a lot more teeth on them.
Ford used the Hyatt caged spiral roller bearings and a spacer sleeve from the model A days to well after the war. In the 50s they changed to loose rollers with thrust spacers and a sleeve. The B-7118-A bearings were the common replacement parts parts from 1928 through 1948 and beyond on Mercury cars & F1 pickups. The current replacements may still be crap. They didn't make them the way Hyatt did. I'd reuse an old Hyatt if it's still holding tolerance on the shaft and in the bore. Last edited by rotorwrench; 06-08-2023 at 11:22 AM. |

Re: What are these inside "NOS" cluster gear?
The model A cars had a long service life. I'm sure that more than one gear manufacturer made gears for these transmissions after they went out of production. Ford likely had parts for them outsourced under contract for quite while. There is no telling what all is out there for them.
A seller shouldn't try to market any part with corrosion or wear as a new or NOS part but there are all sorts of folks out there trying to unload there "stuff". Not all of them can be trusted. Photos, lots of photos are good. |

I have pulled model A transmissions apart over the years and found those spacer rings in the cluster gear instead of the tubular spacer numerous times. I suspect Henry had multiple gear suppliers and it depended on where it came from.
I always knocked them out, so I could better clean the tunnel, then I replaced them with the tubular spacer. Tom Endy |

I'd use that gear cluster. Change the 600W oil after driving it a bit.
