[212 CV] AUXILIARY
DRIVESHAFT
Current production engines (effective February 27,
1992, serial No. 2E1233) feature an improved
“fast ratio” auxiliary driveshaft assembly and oil
pump assembly. This arrangement increases
operating oil pressure by approximately 25% and
creates a change in the oil pump speed. Do not
mix ratios. Refer to Oil Pump assembly
procedures in this section for part number
information.
Inspection
1. Using standard shop procedures, thoroughly
clean auxiliary driveshaft.
2. Inspect auxiliary driveshaft journals, gear
teeth and splines for evidence of cracks,
pitting, scoring or severe wear. Replace
auxiliary driveshaft if any of these conditions
exist.
3. Use magnaflux (PT7190 or equivalent)
inspection procedures to detect cracks.
Installation
앫
Fast Ratio, 1.5:1, part No. 453GC381M
(18 teeth)
앫
Standard Ratio, 1.3:1, part
No. 453GC379AM (17 teeth)
Refer to Figure 6-49.
Purchase the auxiliary driveshaft as an assembly
only. Do not try to dismantle or rework as it may
result in damage to the engine.
It is possible to assemble an auxiliary driveshaft
with a fast ratio oil pump drive gear (5) and a
standard ratio oil pump drive. Do not mix a 1.5
fast ratio assembly with a 1.3 standard ratio
assembly. Damage to the engine will result.
1. Lubricate front auxiliary driveshaft journal
(2), rear auxiliary driveshaft journal (4) and
shaft bearings (in cylinder block) with clean
engine oil.
2. Install shaft (3) into the rear of auxiliary
driveshaft housing. Take care when aligning
shaft through rear bearing (1).
