I have an early trans in my pile, it will give up some nice parts.
My question is ,this trans has the two thrust washers on the cluster gear,I think the later trans dont have these,
Is the difference in the case or the gear compared to a later one
can the case be used with the later gears and can the cluster gear go in a later case
Thanks Lawrie
we have just got back from the A rally in Masterton in NZ,A first class rally, we had the best times there.

Is this unit from a early multidisc unit? If so everything inside but the input shaft will work in a later case. Watch the reverse idler gear and shaft. They are not like the later units. They must be used togather.

Vince Falter (Fordgarage.com) has a good write up of the differences between early, middle, and late version transmission cases.

To summarize on the cluster gear: the cluster gears were identical end to end size through all years. The three earliest version transmission cases used the bronze washers. The change in the 4th version and beyond cases was to "extend" the bosses to make up for the no washer condition.

This and more at https://www.fordgarage.com/pages/atransmissioncases.htm

I have a "type 2" Multiplate case on my work bench right now. I have traced this down to July of '28.

The difference is in the machining of the transmission case. See the Ford Service Bulletin of January, 1929, Page 311, "A change has been made in the transmission case which eliminates the two A-7119 transmission countershaft gear thrust washers...."

I think I have an early case in my bin of parts that even has a snap-ring.

If it has the "small" front hole, it is to be used with the multiplate clutch pak.

Pix of the matching bell-housing (note the "different" access door on top.)

Not worth much without the rest of it.

Note the engine colour on that bell housing. More blue then green. Same as the NOS one on ebay.
Good gearbox cases were hard to get here years ago. Not so much now. Drilling the front bearing retainer holes in the early box for the single plate clutch seemed to work OK.

I have a complete multiple disc setup to get rid of.I don't like them,so I'm going to a single disc.I just put the car in the cellar to start tearing it apart.I took the engine out of my 30 truck to get a couple of cracks fixed,and told him to look closely at the babbit too.I was never really happy with the job somebody did in 05,so I just took it apart to send it out.I hauled the block to the engine shop last Friday,so I put the pickup up against the wall and put the Phaeton in for the clutch conversion.It may be a couple of months before I get my rebabbited block back so I'll have time.I'll be looking to get rid of the complete setup,flywheel,clutch,trans case,pedals,anything related to the multiple disc setup.I'm not sure,but I have done this before and seem to remember the pedal spacing is different,and the upper floorboard has to be changed or modified.Did that one in the 70's,but that little detail keeps floating to the top.I may have been thinking of something else entirely.

My car is March 1928, and I had that access door on my car when I got it in 1994.

Ya can always tell the 28's with the multi-disc because the knurling on the clutch pedal is different. Plus, after the set for a few hours, the pedal tends to fall down to the top of the freeplay position for some reason.

To be truthful, getting rid of that 63lbs flywheel does not really pick up all that much MPH for the amount of work involved to swap things over.

I think the trunyon on the pedal is different too. Think the universals were different in 1928 too.

There are differences, if ya know what to look for.
