Cylinder Lubrication − LFR and HFR Bushes
1. Description
There are two bushes installed on each cylinder lubricating pump (1, Fig. 1).
The low feed rate (LFR) bush (3) is installed on the screw (2) at the bottom of the
cylinder lubricating pump. This bush is for usual operation.
Note: For usual operation, it is not necessary to change the bushes in service.
The engine control system (ECS) always uses the correct value to
calculate the appropriate pump capacity. The correct value in the engine
control system is set after the shop test.
Note: When you install the HFR bush, the output of the cylinder lubricating
pump increases by 34%, compared to the output when the LFR bush is
installed.
The high feed rate (HFR) bush (4), is installed in the storage position. This bush is
used when it is necessary to change the output of the cylinder lubricating pump (e.g.
for running-in or other unusual operations).
To change the bushes, see the procedure in paragraphs 2.1 and 2.2.
