Another odd cluster gear in the batch...25-22-17-14,,and the end is different from the others ..is this for and OD transmission ?
Don't know about the last 3 numbers as I never memorized past the big end. But the 25 tooth is the rarest of the rare, that's for a "25 tooth Zephyr" and has the lowest numerical ratios in intermediate gears of any of the FoMoCo '32-'48 trans. Haven't messed with one of those trans since around '59-'60 so I don't remember the corresponding tooth counts required on the front main drive gear, the 2nd gear, and the low & reverse slider. But I bet if you check around on Ford Barn or if Flat Ernie or Dick Spadaro see this they can offer more info. Dave
Most likely just a different way of cutting oiling grooves on a thrust surface. May even be a different manufacturer made the gears. Dave
The grooves take ears that locate the thrust washer...there are several different washers, plus another odd one from Canada.
That is NOT the L-Z gear you might have hoped for. This is a Ford C2TZ-7113-B (Warner #AWT-8R). It was used with the C0AR-7119A thrust washer. Applications: 1955-56 Ford car - 272 V8 w/o OD 1956-62 Ford F100 truck - 272 & 292 V8 w/o OD 1957-62 Ford F250 truck - 272 & 292 V8
My apologies, but glad you corrected me! Didn't realize that Ford ever used a 25 tooth in anything oher than the L-Z.; Dave
Only difference I find is the thrust washer,,so I don't see why it could not be used. Bore is still 1.125 Also the later 55 gears are much longer than the earlier ( early is like 6 3/4 ) The 24 tooth T - bird gear was used and that is same design Also maybe some later boxes could be pirated for a good gear
Will try to remember to research tooth counts for the cluster...that should be in the Lincoln H series parts book. Have only Ford here.
For one thing, the tooth counts on the other gears on the cluster don't match up with the mating gears on the typical 40-48 LZ gears. Second, the actual tooth shape and design on the 51 and later gears is all different than 1950 and back. The bore size is large to accomodate the larger countershaft used in 1955+ along with the needle bearings.
Yes not a replacement gear,,it is an early aftermarket gear. Which can be used if one is building there own trans. and wish the LZ gearing.
I think perhaps the problem here is that you can't use any of the 51 and newer gears in the early (1932-48) passenger car transmissions because they were closed drive (torque tube) and the early mainshaft will not accept the 51 and newer slider gear....thus none of the rest of the gearset could be used. 1949 and newer passenger car could possibly be set up with that gear however. So, as always.....it depends........
yes and its the 17 gear,,,found a chart ( was posted on the HAMB somehwere ) that tells ya what gear is needed.
The Lincoln Zephyr gear that used a 25 tooth cluster gear had a 25-22-18-14 gear count front to back. The ratios were 2.120to 1 1st gear, 1.430 to 1 2nd gear, and 1 to 1 in 3rd gear. Good to use if you had a light weight rod or something with some extra HP and torque as it was kinda high geared off the line. The other L-Z gear set used a 26-22-18-14 tooth count on the cluster gear. the ratios were: 2.330 to 1, 1.577 to 1 and 1 to 1 in high gear. To use the L-Z gears you needed the Main Drive gear (input shaft) , the cluster and the 2nd gear as these were unique to the Lincoln gear sets.
