The John Deere Model 450B's originally used 9
fiber discs p/n T20716 and 8 steel separator plates p/n T31732 (T20717). When later models
were developed they used bimetallic discs to replace the earlier style fiber discs. The
bimetallic disc part number is T44129. The same numbers of discs were used in all
circumstances. Most of the time you can get by with only changing the friction discs. The
steel separator plates can usually be re-used. Check them for roughness, warping, or
dishing and if they are clean, smooth, and straight, by all means re-use them! To help "steer" you toward creating a superior
steering clutch we wanted to encourage you to use the bimetallic steering clutch discs and
to eliminate the old style fiber friction discs. To do this, we have discontinued the
fiber friction discs to make sure you get a superior clutch.
Because we have now eliminated our costs of buying and stocking the earlier style fiber
friction discs we were able to make the bimetallic friction discs in a larger less
expensive volume, letting us lower the bimetallic disc cost from $29.00 ea to $24.00 ea
When shopping for steering clutch discs or packs of clutch discs
many sellers do not advertise or really tell you what they are selling! You will
often discover, after you buy them, that the clutch pack of discs being offered includes
the inferior fiber friction discs and not the upgraded bimetallic friction discs. We
only sell the higher quality bimetallic friction discs.
STEERING CLUTCH TOOL
When putting your clutch together it is important to get the throwout bearing close to the
3 clutch release levers. JD makes a tool for this but as you have probably
discovered they do not sell the tool, and asking to borrow one, if they even have it,
well.....you are better off writing a letter to Santa. Luckily, Grimy Men stick together and help each
other......You can download a drawing of the tool from our website (CLICK HERE).
If you can print the file on 8 1/2 x 14 legal size paper you will have a good
pattern to get you going. You can get fancy or just make the tool from a manila
folder, cardboard, foam board, or whatever is handy.

The T20717 steel separator plates(used in the earlier JD450's) are often confused
with the T31732 plates used in the later steering clutches of the JD450B's. To be
sure which plates you have in your clutch the thickness should be measured. The
T20717 will measure closer to .087-.09 while the later T31732 discs will be closer to
.097-.099. If the quantity of your discs varies from what is normally required, it
is usually cause by the mis-use of the wrong steel separator plates. The depth of the
brake drum was deeper in the 450B.
 To complete your JD 450B steering clutch rebuild, we have
produced NEW steering clutch pressure plates, complete with
mounting cover, springs, levers and pressure plate.

BRAKE BAND LINING KITS, COMPLETE w/ RIVETS FOR 2 PCE BRAKE

You will have to heat the earlier style bands, scrape and power brush the off the old
glued on linings if you have the glued on linings. Because later brake bands, if
upgraded to the riveted on linings, they will be inconsistent in the placement of rivets.
For this reason these linings are not yet countersunk for the rivets.
