Disc Set I

Disc Set I

• If disc set "I" is being replaced, then the following is required:

• Bearing "D" and "E" for disc set " I" must be replaced => [ Bearings D and E for Disc Set I ] Bearings D and E for Disc Set I.

• Bearing "C" must be checked for wear, and if necessary, replaced => [ Bearing C for Disc Set I ] Bearing C for Disc Set I.

• The shim - 2 - and the circlip - 1 - must be measured again.





• The old shim - 3 - is installed again in any case.

• If, on the old disc set "I", a spacer - 2 - was installed, then this is no longer necessary. The spacer is required only for bearing "D" with an inner race, which is being replaced by the bearing "D" without an inner race.





Procedure

- Remove chain and disc set "I"=> [ Chain and Disc Set I ] Chain and Disc Set I.

- Check bearing "C" for disc set "I" for wear=> [ Chain, Disc Set I and II, Bearing C and Suction Jet Pump, Checking for Wear ] [1][2]Chain, Disc Set I and II, Bearing C and Suction Jet Pump, Checking for Wear, if necessary replace bearing "C"=> [ Bearing C for Disc Set I ] Bearing C for Disc Set I.

- Replace bearing "D" and "E" for disc set " I"=> [ Bearings D and E for Disc Set I ] Bearings D and E for Disc Set I.

Determining shim and circlip





- Install old circlip - 1 - for disc set "I" into the groove on the old disc set "I" - 2 -.

• Installation position: The bores in the circlips eyes are conical. The narrow side point up

• The circlip must contact the base of the groove.

- Determine and note "dimension -a- old" as illustrated.

• "Dimension -a- old" is measured from the upper side of the circlip to the contact surface.

- Install old circlip for disc set "I" into the groove on the new disc set "I".





• Installation position: The bores in the circlips eyes are conical. The narrow side points up

• The circlip must contact the base of the groove.

- Determine and note "dimension -a- new" as illustrated.

If the difference between "dimension -a- old" and " dimension -a- new" is less than 0.2 mm:

• Install the new circlip - with the same strength as the old circlip - and the old shim with the new disc set "I" again.

If the difference between "dimension -a- old" and " dimension -a- new" is greater than 0.2 mm:

• Determine the new shim as follows:





• Dimension - b - is the total disc thickness of the circlip - 1 - and the shim - 2 -.





• "Dimension -b- old" is the old total disc thickness, " dimension -b- new" is the new total disc thickness.









- Put together combination of shims and circlips available, which will result in "dimension -b- new".









• The total thickness of the new shim and the new circlip must not exceed " dimension -b- new".





• Dimension - b - is the total disc thickness of the circlip - 1 - and the shim - 2 -.





• "Dimension -b- old" is the old total disc thickness, " dimension -b- new" is the new total disc thickness.









- Put together combination of shims and circlips available, which will result in "dimension -b- new".









• The total thickness of the new shim and the new circlip must not exceed " dimension -b- new".

Assembling

- Install new chain with the new disc set "I"=> [ Chain and Disc Set I ] Chain and Disc Set I.
