Currently, the maximum clearance between the valve stem and the guide is 0,13 mm (0.005 in) for inlet valves and 0,15 mm (0.006 in) for exhaust valves. As these clearances are difficult to check in service, it is recommended that the procedure given below is used.

Put a new valve in the valve guide. With a dial test indicator on the face of the cylinder head, lift the valve 15,0 mm (0.6 in).

Move the valve radially across the axis of the cylinder head away from the gauge. With the valve held in this position, zero the gauge against the valve head (A). Move the valve radially across the axis of the cylinder head towards the gauge. Make a note of the reading on the gauge. If the reading is equal to or greater than the data given below, a new valve guide must be fitted.

Maximum permissible clearance with a valve lift of 15,0 mm (0.6 in):

Inlet guide: 0,24 mm (0.009 in)

Exhaust guide: 0,32 mm (0.013)

How to Replace Cab Air Filter for New Holland T9.700 Series Tractor

This instruction show you guide on how to replace Cab air filter for New Holland T9.700 series Tractor.

WARNING

Harmful dust!

Properly maintain filters. Keep cab doors and windows closed. Cab air filter, even if it is carbon, does not protect against all substances (e.g. chemical residue on crops). Absolute protection requires product-specific knowledge about potential hazards and how to counter them.

Failure to comply could result in death or serious injury.

CAUTION

Flying debris!

Compressed air can propel dirt, rust, etc. into the air. Wear eye and face protection when using compressed air.

Failure to comply could result in minor or moderate injury.

Preparations:

Doosan Excavator P2035 PDF Inlet Temperature Drift Fault

This instruction show you guide on how to repair Doosan excavator machine P2035 DPF (SCRF) inlet temperature drift fault.

Preparations:

2025 Doosan Data Monitoring System DMS-5

2024 Doosan Diagnostic Software Full Package

Doosan uVIM Diagnostic Tool

1 Overview

“E” SPNFMI

E00324220

REASON:

1 Electrical problem (DPF(SDPF) in temperature sensor connector)

2 Tampering (DPF(SDPF) in temperature sensor is not installed well for tampering, reduced DEF consumption)

3 Electrical problem (Faulty DPF(SDPF) in temperature sensor)

EFFECT:

CE lamp ON Torque Reduction 1(Mild) DPF regeneration inhibit by Active and Forced

2 Component Location

3 Condition for Running Diagnostic

Engine key on after 12hrs soaking.

* The engine soaking time is calculated based on real timer from CAN signal of machine

controller or GPS. And this fault diagnosis is only performed when the CAN signal is valid.

4 Condition for Setting the Fault Code

The DPF(SCRF) in temperature is compared with all other temperature sensors (Inlet air,

Intake manifold, Turbine in, Coolant) at 12hrs soaking condition and if the difference of value

is higher than all other sensors, fault code is raised. (>20degC)

* DPF regeneration is inhibited because the value of the DPF (SCRF) inlet temperature sensor

is not valid.

* If any heating or cooling system is used in engine body and intake / exhaust system, misdiagnosis could be occurred. Therefore, first check if there is a cause of temperature

change when engine soaking condition. (Heating system, Cooling system, etc…)

5) Condition for Clearing the Fault Code

DPF(SDPF) inlet temperature is within normal operation range.

* Even though the root cause problem is fixed, the fault code is remains until to re-diagnosis at

12hrs soaking condition. Therefore, it is necessary to clear the fault code using by the service

tool after fixed the problem.
