Magnetic Base Dial Indicator Set , or equivalent
Note
|
This measurement procedure is intended to measure transmission or transfer case output flange runout for systems with a constant velocity (CV) joint, rubber coupling or bolt-on U-joint yoke at the transmission or transfer case.
|
1.
|
Place the transmission into NEUTRAL.
|
3.
|
If equipped with a CV joint, measure the transmission or transfer case output flange radial runout on the machined surface of the prop shaft front CV joint housing, as close to the flange as possible:
|
|
3.1.
|
Clean the surface of the prop shaft front CV joint housing just rear of the transmission or transfer case output flange.
|
|
3.2.
|
Mount a dial indicator set,
GE-7872
Magnetic Base Dial Indicator Set , or equivalent, and position the dial indicator to contact the prop shaft front CV joint housing as close to the transfer case output flange as possible.
|
4.
|
If equipped with a rubber coupling or bolt-on U-joint yoke, measure the transfer case output flange radial runout on the machined surface of the flange pilot area:
|
|
4.1.
|
Mark the position of the prop shaft to the transmission or transfer case output flange.
|
|
4.2.
|
Separate the propshaft from the transmission or transfer case output flange.
|
|
4.3.
|
Clean the surface of the flange pilot area.
|
|
4.4.
|
Mount a dial indicator set,
GE-7872
Magnetic Base Dial Indicator Set , or equivalent, and position the dial indicator to contact the pilot area as close to the end of the pilot as possible.
|
5.
|
Rotate the transmission or transfer case output flange by hand to locate the low spot.
|
6.
|
Set the dial indicator to zero on the low spot.
|
7.
|
Rotate the flange or shaft by hand and record the amount of radial runout.
|
8.
|
Compare the runout of the flange or shaft to the runout tolerance specifications guideline.
|
9.
|
If the transmission or transfer case output flange runout exceeds the specification, the flange or shaft requires replacement.
