OIL PRESSURE TESTS1. Completely warm up the transaxle.
2.Raise the vehicle by using a jack so that the front wheels
can be rotated.
3. Connect an engine tachometer and place it in a position
where it’s easy to see.
4. Attach the special oil-pressure gauge (MD998330-01) and
the adaptor (MD998332-01) to each oil-pressure outlet port.
When the reverse pressure is to be tested, the 3,000
kPa(400 psi) type of gauge should be used.
5. Measure the oil pressure under various conditions, and
check to be sure that the measured results are within the
standard value range shown in the “Standard oil pressure
table” below.
If the oil pressure is not within the specified range, check
and repair as described in the section “Remedial steps if oil
pressure is not normal” on the next page.

16. INSTALLATION OF SPIDER ASSEMBLY
(1) Pack specified grease amply between the spider shaft
and rollers of the spider assembly.
Specified grease: Repair kit grease
Id
Caution
Special grease is used to lubricate the joint. Do not
mix old and new grease or different types of grease.(2) To install the spider assembly to the shaft, insert the
shaft from the chamfered end of the spider.
11. INSTALLATION OF CENTER BEARING(1) Apply multipurpose grease to the center bearing and
inside the center bearing bracket.
(2) Use the special tools to press-fit the center bearing into
the center bearing bracket.
10.9. INSTALLATION OF DUST SEALS
(1) Apply multipurpose grease to the rear surfaces of all
dust seals.
Dust seal inner: 14
- 20 g (.49 - .71 oz.)
Dust seal outer: 8
- 12 g (.28 - .42 oz.)
(2) Press the oil seal into the center bearing bracket using
the special tool.
CautionTake care not to damage the rubber part on the
periphery of the dust seal.
(3) Apply multipurpose grease to the lip of each dust seal.
NOTEWhen applying grease, make sure that it does not
adhere to anything outside the lip.
