I am reaching out to you guys for your expertise. I have a T18 having a hard time finding a cluster shaft (counter shaft). Mine is a 43-36-27-16, and i can only find 46-36-27-16, why is that? What are my options? i have been able to find all the other parts, except this one.

ford tag on top cover D9T3-CB
40 teeth on the first/reverse slider
13-01-065-904 borg warner casting on the side
PTO cover on one side
F.21.78 13 01 097 906 stamps on top cast iron cover
It is a on a 1975 F250 4x4, married NP205 transfer case, the guy i bought it from said it had "one ton" running gear?

T18 TRANSMISSION CLUSTER SHAFT 46-36-27-16 FITS '65+ FORD JEEP INTERNATIONAL & INDUSTRIAL UNITS (T18-8) - The American Powertrain Warehouse

This is the cluster shaft, everything except the 46 teeth is correct, i need 43 teeth. They have a rebuild kit, reverse/idler gear, and the 1st/reverse slider gear and they are all right...WTF is going on here.

Thanks

Steve

 

They were available with different ratio options; I would contact Novak........

Check the illustration to make sure this is the correct p/n

Also, on your tag (D9T3-CB) I think it's an "A", not a 3, D9TA-CB. I couldn't find any reference to a D9T3-CB.

 

Sounds good, i have a email into novak and american powertrain warehouse, i will get a measurement on that tonight after work.

I wonder if i just change the gear ratio? If it was out of a "one ton" it would have been geared lower. So if i get the 46-36-27-16 cluster shaft, it would change the ratio to a higher ratio, but would i have to change another gear to match up with the new 46 teeth? hmmm....

 

For the price of fixing that one you buy another trans that doesn't have problems

 

that is a possibility, if i can find one that is better shape than mine, that will direct bolt to the transfer case. for a rebuild kit, 1st/reserve slider gear, reverse idler gear, cluster shaft, gaskets, misc parts, is about $500 plus my weekend time. I wouldn't mind spending a little more to know that everything is 100%...if you know what i mean, plus i have all my time of tearing this one down and researching and what not. i have seen rebuilt transmissions ranging from 800 to 1500. my transfer case is already rebuilt, so i cant change style of transmission. I really like this married transfer case setup vs the stock divorced transfer case. i have the original stock transmission and divorced t case setup, its the NP435 but it needs a least a couple gears and a rebuild, but what direct transfer case will bolt onto it?

 

What engine are you using?

 

6.4 L 390 FE big block

I have always wanted a overspeed transmission in this thing, maybe now is the time to figure it out instead of fixing this dang 4 speed. Gets a little tricky with the married transfer case 4x4, whereas putting a OD transmission in a 2wd is easy

on the hwy at 70 mph im pushing 5,000 RPM

 

Something doesn't sound quite right I don't remember 5k at 70 when stock. With 4.10 and 9.50-16.5 which still weren't stock I don't think was around 4k. Regardless it was still high. Anything over drive is going to be expensive. I think you would be just as happy taking the 4.10's out and going with 3.55. Usually used 4 speeds around here aren't really worth anything. The 2wd seems to sell easier around $200. Married setups usually can't give them away even though it's really a better setup.

I thought the input shaft was shorter on the married setups? I wonder how that's working with the FE? Did you get all the ordiginal stuff to put it back to divorced like driveshafts etc?

 

hmmm, ill check on the differential gear ratios,

what is the other numbers your referring too, 9.50-16.5?

 

It's a old tire size around 30" tall. I'm still using 4.10's and 285/75-16 on my 79 F250 and that's great combo. Sure overdrive would be nice but it's tolerable like it is with a tire that's basically 33" tall. With 3.55 it would be real nice on the road but I think I'll keep my 4.10. Your highboy should have 4.10 unless someone changed them to something ridic like 4.56.

 

It's a cluster gear .. there's no such thing as a cluster shaft.

The counter shaft is basic part number 7111 .. it has no gears.

 

tire size good point, let me check which size i have tonight.

NumberDummy, great point, cluster gear, i was mixing up cluster gear and counter shaft, LOL, i will get a measurement on it to confirm, because.....

C5TZ7113E is $500.00 plus shipping at GREEN SALES COMPANY

YIKES so that is out the window, american power train ware house has one for $186 that has 46 teeth vs 43 teeth, would i need to change another gear to make this one work? it would change the ratio, this is where i am waiting for Novak to get back to me.

 

31" tall tires 265 75 r16

4.10 rear 4.09 front axle ratios

That part number that number dummy pointed out measures the same.

American power train ware house doesn't give a part number or length for the 46-36-27-16 cluster gear.

Number dummy do you have any part number for a cluster gear that has the same length measurement but has 46 teeth instead of 43.

I'm trying to figure out other options vs a obsolete 500 cluster gear, I'm not sure WTF to do. I wish Novak or American power train would call or email me back.

 

31" tires, 4.10 axle, 1:1 high gear, 5000 RPM = 113 MPH.

31" tires, 4.10 axle, 1:1 high gear, 5000 RPM, 1.96 low range in your TC = 57 MPH.

Just a thought.....
