MATING MARK
75.10~ Measure the side clearance (endplay) using a
15.10d Install the gears with the marks aligned and
straightedge and feeler gauge facing out
3 Unbolt the oil pickup tube (screen) from the bottom of the pump hous-
ing.
4 Remove the pressure relief plug, spring and plunger (see illustra-
tion).
5 Remove the timing belt tensioner (see Section 8).
6 Remove the oil pump-to-block bolts noting the different lengths and
locations of the bolts. Carefully separate the front case from the engine.
7 Detach the cover from the rear of the case (see illustration 15.4) and
remove the inner and outer oil pump gears.
8 Remove the crankshaft oil seal from the front case (see Section 9).
Inspection
Refer to illustrations 15. IOa, 15. lob, 15. IOc and 15. f Od
9 Clean all parts thoroughly and remove all traces of old gasket material
from the sealing surfaces. Visually inspect all parts for wear, cracks and
other damage. Replace parts as necessary.
10 Install the oil pump outer and innergears and measure the clearances
(see illustrations). Compare the clearances to the values listed in this
Chapter’s Specifications. Measure the free length of the pressure relief
spring and compare the measurement to this Chapter’s Specifications.
Replace parts as necessary. Pack the pump cavity with petroleum jelly
and install the cover. Xghten the bolts to the torque listed in this Chapter’s
Specifications. Note: Be sure to install the gears with the mating marks in
the correctplace (see illustration).
Installation
Ii Install a new crankshaft front oil seal (see Section 9).
12 Install the pressure relief valve components and tighten the plug se-
curely.
13 Using a new gasket, posftion the pump on the engine. Install the bolts
in their proper locations, according to length. Tighten the bolts to the
torque listed in this Chapter’s Specifications.
14 Reinstall the remaining parts in the reverse order of removal.
15 Add oil, start the engine and check for oil pressure and leaks.
16 FlywheeUdriveplate - removal and installation
Thisprocedure isessentiallythesameforallengines. RefertoChapter
