Cooler Service And Cleaning

Clean the coolers and surrounding areas of dirt, debris and buildup daily. The radiator, A/C condenser, hydraulic oil cooler and charge air cooler should be a part of everyday routine maintenance.

Clean the area around the engine at this same time to eliminate build-up from crop debris and chaff.

  1. CAUTION: To prevent injury, never service windrower while it is running. Engine must be off and key removed.

    Turn off engine and remove key.

  2. Raise engine hood completely.

A - Rotors

B - Retaining Nut

The cooling box screen is equipped with an automatic cleaning device that vacuums the screen by means of two rotors. They only operate when the engine is running. The rotors are electrically driven, and the suction is provided by the engine cooling fan.

It the screen is not being cleaned by the rotors they may be plugged.

If rotors (A) are plugged, clean screen as follows:

  1. Park the windrower on a firm, level surface.

  2. Stop engine and remove key.

  3. Raise engine compartment hood fully.

  4. Remove retaining nut (B) at the center bottom of cooler box.

B - Retaining Nut

C - Motor Support

D - Motor Mount Bolts

E - Motor/Duct Assembly

F - Screen Access Door

G - Screen Assembly Latch

Check rotor clearance between trailing edge of rotor (A) and the screen. It should be 1 - 8 mm (.04 - .32 in.) at all locations when rotating.

If necessary, adjust clearance as follows:

  1. Loosen retaining nut (B) on motor support (C).

  2. Move support in or out until duct is 2-6 mm (0.08-0.24 in.) from screen near the center.

  3. Re-tighten nut (B).

  4. Loosen the two motor mount bolts (D).

  5. Move motor / duct assembly (E) to obtain 1-8 mm (0.04-0.32 in.) gap to screen at full rotation of the duct.

  6. Re-tighten nuts (D) on motor mount.

  7. Close screen access door (F) and engage latch (G).

  8. Lower engine compartment hood.
