-
The oil additives (detergents, etc.) could be depleted.
- Leakage of coolant into the luba oil can caused
severe sludging.
2.
BLOATED SPIN ON
Spin
On Filters are designed to withstand pressure approximately
5 times greater than normal pressure in the lubrication
system. In the event of excessive High Engine Oil Pressure
that is produced by the pump the spin on may be severely
damaged, and caused oil leakage
3.EXPLODED
FILTERS
Element
type filter are designed to flow from outside to
inside.
The most common cause for this problem is reversed
oil lines leading to and from the filter housing
4.
COLLAPSED FILTERS
Full
flow filters both element and spin-on are protected
by a safety relief or by pass valve and valve setting
is approximately 25 PSI
It is probably caused by the media being excessively
plugged with contaminants and a faulty by - pass
valve
5.
WRONGLY FITTED FILTERS
* Misapplication Oil Filter and Fuel Filter
* Reversed side Top and Bottom
* Different thread size used
* Misapplication Full flow filter & by Pass
*Cleaning bolt and the surface of filter bracket
* Does the filter have adequate strenght?
*Seal
filter improper seated on the bracket because dirt
on the surface of the bracket or defective at the
center bolt.
*The center bolt lose cause filter lose and oil
leakage
*
Seal packing / Gasket
· Function: to endure pressure
· Use correct component. Others component
although similar may not be the same
·
Mounting seal packing
Apply oil to the seal before fitting the filter
and ensure the seal is in the correct position
