  • Cluster Gear Differences

    I am getting ready to rebuild the transmission for the delivery sedan. It is a March or April 1929 built car, but still has the case with the machined bearing surfaces and the cluster gear with the permanent spacer. No thrust washers like on the earlier 28 style transmissions I have rebuilt. The only good cluster gear I have is a later one with the removable bearing spacer. Is there anything to look out for using the later cluster gear in the early 29 case? My only other option is using one of my later cases. Thanks Rod

    I think you're good to go, so long as there isn't too much clearance between the cluster and the case. just my opinion

      That was my thinking also. I was suprised to find this style of case and cluster gear in a March/ April built chassis. Although I have 14 cases, I prefer to use the case that came with the chassis and is likely original to the car. I do not see any evidence this transmission has ever been apart. It is a 67K mile chassis. Rod

    The cluster gear with the non removable bearing spacer, is that a tight ring pressed into place, or is it actually just one piece of metal?

      I beleive it has the tight rings, but would have to dig it out of the scrap iron bucket and hope to dig out the right one. I guesse there are 6 or 7 of them in the bucket after all of the disassembly. Still have 2 really rusted transmissions to deal with. Doubt I can save anything beyond the cases. So far I have been unable to remove the u-joints from either, so both are being sprayed with PB Blaster a couple of times a day. I cut one yoke of the u-joint on each and still could not remove them with a gear puller. Front bearing retainer and main drive gear are removed. Rod

    Timely topic for me. I tore apart my early 29 transmission today with no thrust washers and non-removable bearing spacers. They appear to be two pressed in rings to locate the bearings. Between the 2 rings is rough machined, not like where the bearings ride.

    I also have a donor transmission a guy gave me several years ago. It is the later style. The case is junk but I am hoping to use the universal joint and gears from it because they look better than my original.

      I hope you have better luck finding good cluster gears than I have had. Took 14 transmissions to find 2 nice cluster gears. I had better luck with the early 28 transmissions I rebuilt. Was able to find about 1 good cluster gear every 3rd transmission. Rod

    Spare Transmission
    by JohnB15632
    Rowdy's Post Who got this awesome Deal, got me thinking.

    Is there any way to determine if this transmission or any of its parts are original?

    This transmission came with my A when I moved it to my garage.

    Than you.

    Speedometer gear case
    by DBaldwin
    Doing my research I have a 4:11 rear gear however I cannot find a complete speedometer gear case that has the proper 21 tooth I see 18 and 19 tooth for the 3:56 and 3:78. This means I’ll have to buy a new complete case and then a new gear to put in it unless someone can point me to a source with a complete 21 tooth assembly. Hopefully someone can help me out on this one. This is for a 30-31 pickup....

    Rebuilding the Tranny
    by Tom Wesenberg
    Yesterday I rebuilt Mark's tranny, and had to replace the cluster gear and bearings. The good used cluster gear didn't have the bearing spacers installed, so I had to remove the old ones to install in the good cluster gear. Notice the flat side must face the bearings, and they get installed just far enough for the bearing to be recessed about .020" to .030" from the face of the cluster gear....

    Transmission cluster gear spacer?
    by AzBob
    Upon removal of the cluster gear, I found an extra roller bearing (long one) installed instead of a spacer. The extra bearing is one of the “dimpled" retaining ring type.

    Does anyone know the correct length of the spacer?

    Multi-year transmission
    by Nsieber
    I just started rebuilding the transmission for my 1930 sedan, and I noticed a couple of interesting things. First, the cluster gear had brass thrust washers at each end, which I believe were for pre-1929 transmissions only. Second, the cluster gear had the spacer in between the two needle bearings, which according to the Model A Mechanic Handbook, is for after October 1929. I know the previous owner...

    cam gear.
    by canadian
    trying to sort out a engine noise . removed cover for timing gear , have a small amount of backlash movement but noticed that gear is a little loose seems around centre somewhere. fibre gear . question can this be replaced in car? I have a aluminum one on hand, are these recommended ? or worst ? also can cam gear come off on it own or does both gears have to come off at same time? thanks

    Strange Ring Gear Wear

    Saw this ring gear on Ebay . What would cause it to wear like this, almost like it was made off center.

    Pinion Gear jamming with Flywheel Ring Gear
    by saxman657
    I've had the pinion gear jam with the flywheel ring gear several times within the past 4 weeks or so on my 1928 Tudor. I was able to pull the starter and inspect the Bendix and flywheel. Bendix moves freely and starter operates fine with bench test. I do have some marks on the pinion gear as well as on the flywheel gear ring when viewed through the the starter opening (see photos). First jam I...
