John Deere 450B Crawler Dozer
JD450B STEERING CLUTCHES

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 are discontinuing the fiber friction discs and they will not be provided after their stock runs out.
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, thereby lowering the bimetallic disc cost from $29.00 ea to $23.00 ea.

JD450 450B BIMETALLIC & STEEL DISCS
 

T31732_JD450B_CLUTCH_PLATE.JPG (93829 bytes) 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 rhw JD450B's.  To me sure which plates you have in your clutch the thickness should be measured.  The T20717 will measure closer to .087 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.
