EVERY 100 HOURS carry out the preceding
checks plus the following :
Operation 23 - Fuel Injection Pump Oil Level
Remove the Fuel Injection Pump Drain Plug, Figure
20, and check the oil level. If necessary, add oil from
the Filler Plug and wait till the excess oil drains out.
Refit the Filler and Drain Plugs.
Clean the area around the filter. Smear clean engine oil
around the rubber seal of a new filter and install on the
tractor. Screw up until the faces just meet, then tighten
a further ¾ of a turn. Do not overtighten.
Replace the drain plug, remove the filler plug, Figure
23, and refill the engine with clean oil. Replace the filler
plug.
Run the engine for a minute or so, to circulate the oil,
then stop the engine. Wait for a short period to allow the
oil to drain back to sump then check the oil level by
means of the dipstick.
Add clean oil, as necessary, until the oil reaches the
upper mark on the dipstick.
See Section C for correct oil grade.
EVERY 300 HOURS carry out the preceding
checks plus the following :
The following text depicts the normal 300 hours engine
oil and filter change period. However, engines operating
in temperatures below – 12°C (10°F) or in arduous
conditions should have the oil changed every 150 hours
of operation. (the oil filter need only be changed at the
normal 300 hours service interval).
In some territories, locally available diesel may have a
high sulphur content, in which case the oil change period
should be adjusted, as follows:
*
Diesel fuel sulphur content below 0.5% - normal
oil change period applies.
*
Diesel fuel sulphur content between 0.5 and 1.0%
- reduce oil change period to half of the normal.
*
Diesel fuel sulphur content between 1.0 and 1.3%
- reduce oil change period to one quarter of the
normal.
The use of diesel fuel with a sulphur content above
1.3% is not recommended.
Operation 24 – Fuel Injection Pump Pre-Filter
