||The John Deere Model 450's ("plain"
model 450) originally used 8 fiber discs p/n T20716 and 7 steel separator plates p/n
T20717 (T31732). 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
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

The T20717 steel separator plates are often confused with the T31732 plates used in the
later steering clutches. 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 discs will be closer to .097-.099. If the quantity of your discs varies from
what is normally required, it is usually caused by the mis-use of the wrong steel
separator plates. The JD 450B used the thicker plates.
To complete your repair of the JD450 steering clutch, we have produced NEW steering clutch pressure plates, complete with mounting cover,
springs and levers.

RIVETS FOR 2 PCE BRAKE BAND $65.00
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.

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.
Using the above tool, you can follow the workings of a
fellow Grimy Man who has sent some pictures
and narrative on how he worked out the clutch adjustment. This may help you in your
steering clutch adjustments. (CLICK
