2.25 injection pump filter change
By: eddie hitler Date: February 17, 2012, 3:19 pm
---------------------------------------------------------
my attempt at a how to thread...
at work a 2.25 injector pump came in with a lack of power and
poor starting, the owner had changed the fuel filter, draind the
tank and flushed the fuel lines after some 'dodgey' diesel had
been used.
there is another filter in the inlet of the injector pump.
changeing this filter is a relatively esay diy job (however his
pump was too far gone hence its part-striped state)

this ally casting is the transfer pump housing, before unbolting
slacken but do not remove the 24mm plug on top, then remove the
four 8mm bolts holding the casting to the head (the steel bit)
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/start14.jpg
remove the casting
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/start8.jpg
at this point it is wise to replace the transfer pump blades ,
these are made of graphite and are quite easly broken
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/start10.jpg
remove them with a pair of long nosed plyers
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/start19.jpg
gently push the new blades in, you might need to lubericate them
with diesel
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/DSC01004.jpg
back to the filter, take the casing inside as there are a few
small bits that if droped wont be found again! unscrew the top
plug and remove the spring or tip the contents on to the bench
(2 springs a spring cap/shim and a piston)
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/DSC01005.jpg
carefully remove the plastic filter with a small screw driver
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/start3.jpg
the old filter next to the new one, this ones in a very bad
state
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/start5.jpg
as can be seen by the amount of muck removed
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/DSC00995.jpg
with the filter removed the rest of the inards should fall out
from left to right, hair spring, piston housing, piston, small
spring, spring cap, main spring and filter.
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/DSC01007.jpg
remove whats left of the card washer (some may be on the housing
and some left inside the casing) and replace with a new one.
to reassemble put the hair spring back into the bottom of the
casing, it can be a pain to get to to lie right.
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/DSC01006.jpg
place the piston in its housing (it's not handed) and replace in
the caseing (the card washer end down)
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/DSC01017.jpg
next the filter...
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/DSC01015.jpg
then the small spring (shown without the filter)
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/start27.jpg
this is the spring cap the end with the three lines sits inside
the large spring. a small amount of grease may be needed to hold
it into the large spring
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/start28.jpg
fit the large spring then replace the 24mm cap useing a new
copper washer
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/DSC01028.jpg
replace the seal between the head and the casing
HTML http://i446.photobucket.com/albums/qq190/eddie_hitler/DSC01029.jpg
screw the casing the back onto the head being carfull to line
the dowel and the slot up. these screws only need a little more
than a nip.
thats it i hope this was helpfull (and readable )
:lol:

Cool post!
Does this filter exist on the 2.5d and td engines as well? Might
check mine

Looks good, good write up.
Are you saying that the seals are the only thing that needs
doing or is there any calibration that also needs doing?

on that bit its just seals no setting needed
and the 2.5 is similar but not the same in this area
cheers

sorry to butt in but have you got a clue about how would a worn
distributor pump sound like?
does it sound rattly when using a long screw driver against its
body and ear?
