[AJD] 1939 B front tire size

Sun Dec 4 11:55:35 PST 2005

Chris:

Better send that request to the "Two Cylinder Magazine". The CC doesn't do
the serial number research any more. In fact I believe the magazine had a
note in it recently about a certain deadline in order to receive a response
by Christmas. It does take awhile. I have wondered a bit why it takes so
long. It is my understanding the JD hired Two Cylinder Magazine to enter the
hand written data into a computer data base some years ago. I don't know if
that was totally completed. But if most or all of the data is stored on
computer, it would seem to me to be a somewhat trivial task to search on a
serial number and print out the results. Must be something more to this than
I am aware of. It may be nothing more than someone of the staff who has
multiple jobs to take care of.

Duane,

    Thanks for the info. So it looks like my wheel configuration in correct,
or was at least a possibility.  I guess I will have to shell some money out
to the collector's center for some s/n research one of these days.

                                     Chris

  The following information is for rubber tire wheels only.
A 1939 B came from the factory with the following front wheels: 
AB1023R-version 2 with a3.00Dx15 rim for a 5.00-15 tire. version 2 means 
the center wheel is riveted to the rim at 4 "flutes", with 2 rivets/flute. 
Sometime in the early '40 model year AB1023R-version 3 was used, and it had 
four "hand holes" where the wheel meets the rim. That was followed by the 
JD1262R reversible rim at B153376.

Rear wheels had more options. A B1545R (casting, not part number) had a 
cast-in hub and used a B1189R clamp. Several rims were available. A 
"conventional" rim for 7.50 or 9.00-36 tires was used until 81792, at which 
time Deere generally made a change to "wide base" rims and tires so a 7W-38 
rim was used for an 8 or 9-38 tire until early 1940 when a 10-38 option 
became available. Note a 9-38 tire then would be a 9.5-38 tire now.

Pressed steel wheels also became available at the change to wide base tires,

and at 81793 the JD1250R wheel with a 7W-38 rim for a 8 or 9-38 tire was 
available.

A flat spoke rear wheel (JD1240R) was used, but became an option at 81793. 
The JD1240R used a B1189R clamp and had a 6.00S-36 rim for 7.50 or 9.00-36 
conventional tires. However, it had hub breakage problems and was replaced 
by the JD1259R flat spoke wheel at 102683, which also had problems and was 
replaced by the JD1270R flat spoke wheel with a bolt-in hub at about 191300.

Both of these last two wheels were replacement wheels only.
