2.9.16 Determining cross shaft bearing adjusting disk Q1
The bearing unit in the cross shaft lid is installed using adjusting disk Q1 with
compression. Determining adjusting disk Q1 requires measurement device Porsche
spare part No.: 991.450.348.9A.
Measurement process
Insert measurement device Porsche spare part No.: 991.450.348.9A in the cross
shaft lid. The touching surfaces of the components must be free from dirt.
The measurement device is clamped in with locking ring Porsche spare part No.:
900.042.049.01. The locking ring that is also ultimately used for installation must be
used (Figure 2.9.16.1)
Aligning the depth caliper
Carry out the distance measurement (Figure 2.9.16.2) from stamp end to ring disk
(1). Carry out three reference measurements (20.10 mm)
Measure the total length of the measurement device (2) (62.09 mm)
Measure the total length of both bearings (Figure 2.9.16.4) (39.95 mm)
Calculating the Q1 measurement
Total length of the measurement device – total length of the bearings – distance
measu compression (0.15 mm) = adjusting disk Q1
Example:
62.09 – 39.95 – 20.10 + 0.15 = 2.19
As a consequence, an adjusting disk with a thickness of 2.19 mm must be inserted.
