Removal and Installation
REMOVAL- 1.Remove the front diffuser. Refer to Exploded View.
- 2.Remove the sub-muffler. Refer to Exploded View.
- 3.Remove the heat insulator.
- 4.Separate the front propeller shaft assembly. Refer to Exploded View (GT-R certified NISSAN dealer).
- 5.Drain the transmission oil from the transmission assembly. Refer to Draining.
- 6.Install the flange wrench (commercial service tool) (A) to the companion flange of transfer, and then remove the mounting nut.
- 7.Remove companion flange using a puller (commercial service tool) (A).
■ CAUTION ■
Never damage the companion flange.- 8.Remove the front oil seal using the puller [SST: KV381054S0 (J-34286)] (A).
■ CAUTION ■
Never damage case. INSTALLATION Note the following, and install in the reverse order of removal.
■ CAUTION ■
Apply anti-corrosion oil to threads and seat surfaces when installing the companion flange mounting nut.- Drive and install the front oil seal to the case end surface using a drift.
A : Drift [SST: ST30720000 (J-25405)] B : Drift [SST: KV40104830 ( — )] ■ CAUTION ■- Never reuse oil seals.
- Check that the grease is applied to the lip and all inner walls of oil seal. Apply multi-purpose grease or equivalent if the grease is not applied.
- Never use including extreme pressure additives.
- Never incline the oil seal during installation.
- Never allow oil and dust, etc. to get on the oil seal press-fitting surface.
- Never damage the oil seal.
- Never damage the front drive shaft when installing the oil seal.
NOTE：For OK/NG judgment of oil seal installation, measure the oil seal press-fitting depth (on 2 locations or more) and check if they exceed the dimension “A”. Always calculate the dimension “A” before measurement. Dimension “A” can be calculated by the formula below.A = B − C − 0.5 mm (0.020 in) A : Oil seal press-fitting depth B : Case depth C : Oil seal flange thickness 
- Never reuse oil seals.
- Fill with the transmission oil to the transmission assembly after installation. Refer to Filling.
