I swapped my 5:38 axles for 4:27. The speedometer is now about 20% low. Using original 31" tires with T18 transfer case. What would be the new gearset needed. Is it available? Mike
GK:
My 57 Wagon is all original with 4.27, has a 19 tooth driven gear and is accurate. My 62 Wagon has 3.54 axles and a 17 tooth driven gear original. Both have the original T90 trans and spicer 19 transfercase

Sorry, a different drive/driven gear for your speedometer isnt available. Good news is you'll never get a speeding ticket in a Willys.

If fluid is leaking out of the speedometer cable and this housing area for 47 willys cj, how does replacing this seal? Are there o-rings, etc built in?
Willys Jeep Parts Tech:
There really is no seal there. So either the transfer case is over filled or your missing/clogged the vent part number: A934 due to pressure build up.

What size socket do I need to remove the old set up? The old speedo cable broke inside and I need to get it out.
Willys Jeep Parts Tech:
I would just use a hex head wrench and it will screw off the housing.

Will this gear accept a ‘universal’ speedometer cable? I changed speedometers (equus) and the original cable won’t connect to the new gauge.
Willys Jeep Parts Tech:
As long as the speedometer cable is designed the same way the 643797 cable that originally was used.

‘52 m38. Current gear has a half moon shaped shim to hold the cable end. This gear appears to have a square hole to accept the cable end........ is that the case?
Willys Jeep Parts Tech:
Yes, see MSPEEDOCABLE part number. You can see the tab on the inner cable.

I want to be sure about this. This gear set WILL fit in my M38a1 transfer case and allow me to use a Civilian speedometer?
Willys Jeep Parts Tech:
Call and as for Mike M. I can confirm this.

Where the side bushing screws into the transfer case, should there be an O-ring or washer of some type to prevent oil from seeping out?
Willys Jeep Parts Tech:
You could use some permatex if you wanted.

Do I need product number A1511 also if I purchase this? I disconnected the cable today and spun the tab. The needle on the speedometer flicked up in relation to me spinning the tab. I removed the insert where the cable connects and tried pulling the gear out. It was loose but didn't come out. I decided not to force things at that time. I just want to make sure I'm buying everything I need to replace the internals of the speedometer system at the transfer case. With my luck it's probably just the cable itself. HA

Yes, they mate to each other to turn your speedometer.

Hi, my 66 cj5 v6 has had the single lever transfer replaced by a twin stick by the previous owner. when diagnosing why the speedo did not work I found that the driven gear that exits the T/C is round with a slot in it like the M38A1 . Will this gear allow me to use the stock speedo cable with the square inner cable? Thanks in advance.
Willys Jeep Parts Tech:
This would allow you to use 643797 original cable.

I have 1962 willys pick up with dana 18 t/c. i went from stock height tire to a 285/75-16 or 33". what t/c speedo gear would i need to get to fix this speedo cal? Thank you
Willys Jeep Parts Tech:
I don't think there will be much you can do about your speedometer being off. There really are not many options on the speedometer drive / driven gears. Only what is original is available.
