Fuel System Points to consider in field on pumps fitted with IKSB
35 Series 4WD, Model - 3535, 4035, 4535 and 5035 SM June’08
1.
It is advised not to attempt to remove the IKSB unit or loosen it for priming purposes under any circumstances. Bleeder screw in the distributor head can be loosened to remove air trapped in FIP.
2.
Ensure that 12V is connected to IKSB unit when abnormal smoke is seen in the field during cold operation.
3.
When the IKSB unit is energized / de- energized, marginal difference in noise may be observed due to advance in cold and retardation in hot conditions – This is absolutely normal.
4.
Do not attempt to handle the pump / lift it holding the IKSB unit.
5.
When the vehicle fails to start in cold condition, check if the 12V is connected to IKSB solenoid. Check if battery voltage is 12V.
6.
During hand priming using filter ensure that the ignition key is OFF, bleeder screw in filter is loose. DO NOT attempt to prime the system with ignition key ON as it may impart additional resistance to filter hand primer. As a last resort bleeder screw in the pump (center of DV ports) may be opened for priming purposes.
7.
In case of suspected problem with the pump, the pump is to be handed over to the authorized BOSCH dealer in undisturbed condition, IKSB should be in undisturbed condition.
8.
IKSB unit of one pump should in no circumstance be replaced on another pump without calibration of the pump.
