Louver Length

H89699

A - Wire-To-Wire

Machines can be equipped with two different types of chaffer and sieves.

  • Deep-tooth chaffer and sieve.
    • Chaffer 41 mm (1-5/8 in)
    • Sieve 30 mm (1-3/16 in)
  • General-Purpose chaffer and sieve.
    • Chaffer 30 mm (1-3/16 in)
    • Sieve 30 mm (1-3/16 in)

Proper way to measure chaffer and sieve louver length is from wire-to-wire (A) as shown. This can be used to determine if a deep-tooth or general-purpose chaffer or sieve is installed.


Sieve Louver Depth

H120674
H120674-UN-02FEB17

A - Louver Depth

Machines can be equipped with two different types of sieves.

  • Deep-tooth sieve.
    • Sieve 22 mm (7/8 in)
  • General-Purpose sieve.
    • Sieve 10 mm (3/8 in)

Proper way to measure sieve louver depth (A) is from bottom of louver to tip of louver as shown. This can be used to determine if a deep-tooth or general-purpose sieve is installed.


Louver Clearance

H92974
H92974-UN-03OCT08

A - Louver-To-Louver

Always close the chaffer/sieve louvers past the desired set point and then open the louvers to the desired set point to remove play.

Proper way to measure chaffer and sieve clearance is from louver-to-louver (A) as shown. This can be used to determine if clearance on chaffer and sieve matches with setting shown on armrest display.
