Read the instructions carefully. The items refer to the parts list and service kits section.
Drawing 18
Nozzle Carrier Body Assembly
Remove the Nozzles (pos. 36) from the Nozzle Carrier (pos. 33.1). Inspect the Stream Straighteners (pos. 37) inside the Nozzles
for debris or damage. If the Stream Straighteners are damaged or worn, remove from the Nozzles for replacement.
Inspect the Nozzle Housing Cups (pos. 32) that are pressed into the Nozzle Carrier (pos. 33.1) for severe scoring or wear. If
either Cup is worn, they should be replaced as a pair.
Check whether the Nozzle Housing Bevel Gear (pos. 31) can be rotated and inspect it for worn, sharp, or damaged teeth.
If the Bevel Gear can be rotated but its teeth are not damaged AND the Bearing Cups are not significantly worn, an arbor press
can be used to press the inner Bearing Cup back into the Nozzle Carrier until the Bevel Gear is held in place.
If the Bevel Gear requires replacement, the inner Bearing Cup will need to be removed, at which point both Bearing Cups should
be removed and replaced together.
If the Bevel Gear is being replaced, the Bevel Gear Location Pin (pos. 33.2) can be inspected as well. Confirm that the Pin is
firmly seated in its hole in the Nozzle Carrier and is not deformed or worn.

Tee Housing Assembly
Inspect the Tee Housing Bearing Cups (pos. 24.2) inside the Tee Housing (pos. 24.1) for severe scoring or wear. If either Cup
is worn, they should be replaced as a pair.
Inspect the nose of the Tee Housing (pos. 42) for any debris or blockages in the windows. Check that the nose is coming
straight out from the main of the part and is not bent or deformed.
