Hey NumberDummy when you have a chance after your visit with your sister then please tell me if by chance if the 62 school bus I have with a 4 speed in it might also be a T-98? What I read they used the T-98 up to 64.


The front tires or flat and can't get under the thing easy but my friend with the 56 said he could get to the speedo gear by removing the metal cover in the old bus.


The number plate that I found in the bus does not give me any info but the numbers on the title might but even then might not have what I need. I know there is a large rear end under the thing. The rear in that is in the 56 going by the number is a 392. And the one in the bus has to be in the 4's I would guess?


Well I know this I guess and it is a f-750 Here is the vin number B75FV291605.


Dag my eyes are like having what you call floaters and driving me nuts.

 

Sister is here, so I cannot spend much time. Your 4 speed is a T-98, but what series is the bus? B500, B600 or ?

 

Thanks Bill. Family first.

I kind of hijacked his thread but, we're all benefiting from this info. I am looking for the drive gear. The OP is looking for the driven gear.

Scott

 

The overall length is 3&1/4" long.
The end shaft for speedo cable connect is 15/32"

 

Look at post #16 again, I edited in the sources.

 

Only thing I see and that is on the hood pieces is B750. I guess we will know more once my friend can get to the gear from the shift cover like he said he can do? And then hope he does not drop it HA HA.


Thanks for the pictures and the measurements jmadsen From the looks of the end of his old one then right where the indentions are on your picture that is what is broke off.
He can get the cable in there if he sticks it in first but then has to wiggle the cable to put the piece on the out side on that holds it all in place. When he checked inside the cab he could not turn the cable but he guess that when he went to connect it back up then it pulled out of the gear.
The use of some super glue or JB Weld might do the trick but if he ever wanted to have it calibrated then it couldn't.


It is still strange that the tip of it broke off? But I guess that is what it is meant to do so it would not damage the gear in the trans or anything else. The old oem cable was stuck real good and he like to have not even got it out.

 

Do you know the rear axle ratio and tire size for the B750?

 

Tire size would be easy once I walk back down to my shop but the axle ratio I would have no idea unless it is either on a plate or stamped into the housing or axle tubes? That end of the bus is higher and can be got to if I want to crawl in the sand. But would like to know where to look if I am going to do that.
Here is what I found. Tires 900x20 this number was on the rear/right housing?? 1681 this number was found on like a paper like tape maybe wrapped around the housing near left next to the U bolts E2.19? That is all I could find or at least easy. If there was ever a tag then long gone.


Gee now is the time I wish dogs could read and give me that info. They go under it all the time


Just to make sure I understand the speedo gear correct and I would guess the fewer the teeth it has would be what would really be needed to get it to read closer than it would with like the 20 tooth one that is in it now. Is that correct?


Am I correct that if we ever found one with less teeth then the gear inside the tranny would have to be one or it?


Thanks

 

01Y-17285-A .. 18T DRIVE Gear / Obsolete ~ 11 available NOS

01Y-17285-B .. 19T DRIVE Gear / Obsolete ~ 8 available NOS

Pick the one you want, I'll list the sources.

If you want the 01Y-17285-C .. 20T DRIVE Gear / Obsolete - See post #16.

If you want the DRIVEN gear, I will need to know the type of rear axle and the ratio.

 

Well we know the 20 tooth was in the tranny for what ever it came out of and was not made for this truck according to the numbers. Even with a 20 one put back it will be off and we expect that.


From what I just read if we want to slow it down then it needs more teeth but if wee want to speed it up then we need less teeth on the drive gear.


I just copied all the info on post #16 Thanks With us not knowing how much it is off then I would guess the best bet would be just stick with the one that was in it and if all goes well at least it will read something and then go from there.


But what other gears would work with out having to change the driven gear inside the trans? You could change the nylon ones back in the day and have done so but I guess there is even a limit that you could use before you destroyed the teeth?


You tell me on the driven gear that would be needed if you can.


Thanks

 

Well number dummy this is not going very well. Wrong gear! the 01Y-17285-b shows up all over the place as the nylon gear that goes inside the trans and not for sure what we need?
Here is what you find using that number even on the Carpenter site
Speedometer Gears


Do I need to call them and they tell me what they have in their hand an looking straight at it maybe?


If not looks like we are back to sq one and need on like pictured a few post above #20 and my 1st post and it is an 01T-71 C-20 or close. So I guess we pull the one out of the old bus and see what it had.

 

I don't give a damn what others are calling it, NONE of the 01Y DRIVE gears are nylon.

I have been looking these gears up (introduced in 1940) in parts catalogs for 45 years (I'm 15 months older than you), so I know what the hell I'm talking about.

Call one of the sources and ask for a description.

 

Driven gear.




8J-85-7<br/>At least appears to be a 7?

 

This is the DRIVE gear on the output shaft of the TRANS. The DRIVEN gear is at the end of the cable where it fits into the trans.

Counting across, this ^ is 8J-17285 7 tooth DRIVE gear. Is this the gear the OP wants? Obsolete ~ available NOS

Pic: DRIVEN gears .. TYPES 1 -2 -2a are nylon, TYPE 3 is 01Y
