- 525B (S/N: 3KZ1-UP)
- 535B (S/N: AAE1-UP)
Description of Change: A new radiator is used on the machines that are listed. The new radiator uses bolted joints instead of the former soldered joints. The new shroud uses hinges that improve access for cleaning. The new radiator improves service life.
Adaptable To: The new 221-2659 Radiator replaces the former 156-5881 Radiator. The new 221-2659 Radiator uses a new radiator shroud that is not adaptable to the former 156-5881 Radiator .
The new 221-2659 Radiator was effective with 525B (S/N: 3KZ796, 826 and 835-UP) Wheel Skidders and 535B (S/N: AAE569 and 571-UP) Wheel Skidders. The new 221-2659 Radiator is adaptable to first production of the machines that are listed.

| ( 1 ) | The later shrouds will use the original M10 hardware. The later shrouds will not require the new M8 hardware. |
Note: Some earlier shrouds used weld nuts. These shrouds will require twelve 8T-4908 Bolt. The later shrouds used M10 weld nuts. These shrouds will use the original M10 bolts.
Note: The new radiator shroud is 26 mm (1 inch) wider than the former shroud. Therefore, two 224-5631 Plates are required in order to mount the condenser to the shroud. Four 1W-5040 Spacers and four 8T-4182 Bolts can be used as a substitute for the 224-5631 Plates. The spacers can be installed between the condenser core and the rubber mount. The 8T-4182 Bolts are used in order to mount the condenser to the bracket. The bolts are also used in order to accommodate the 1W-5040 Spacers.
