TECHNICAL SERVICE BULLETIN
BEARING CLEARANCE TESTER (BCT) PROCEDURES
 NOTICE
This bulletin has been revised to include additional information. New/revised sections of this
SUBJECT:
bulletin

are indicated by a black bar in the margin area.

This bulletin provides information regarding test procedure of the Bearing Clearance Tester (BCT) Special
Service Tool (SST). The SST comes pre-calibrated from the supplier however, in some cases, due to variable
shop compressor air pressure, the SST may need to be re-calibrated to ensure that the tool provides accurate
readings when testing the engine rod bearing wear. The calibration and BCT measuring point maintenance is
included in this bulletin. Follow the procedure outlined in this publication to perform the BCT procedure for
the applicable engines listed below:
•

Addition of Blue Loctite to BCT Measuring Point refer to page 2

•

For THETA 2.0L-T/2.4L GDI ENGINES refer to pages 3-11

•

For THETA 2.4L MPI, GAMMA 1.6L GDI and NU 2.0L/2.0L-T GDI refer to pages 12-19

•

BCT Calibration Procedure refer to page 20-23

 NOTICE
It is recommended that the SST is always connected to a known good air supply that is consistently
providing the same air pressure to the SST when using. Switching the SST to multiple different
locations is not recommended for this reason. Do not use a portable air compressor ever.
A printed copy is for reference only; publication information can be updated at any time.

BEARING CLEARANCE TESTER PROCEDURES
ADDITION OF BLUE LOCTITE TO BCT MEASURING POINT
This outline provides information regarding the application of Loctite® Threadlocker Blue 242 to the dial
gauge ‘measuring point’ end included in the Engine Bearing Clearance Tester (BCT) kit SST KQ231
2T110QQK. This extra step helps reduce the possibility of the measuring point tip loosening on the dial
gauge due to repeated use. If measuring tip comes loose, inaccurate BCT measuring readings will result.
This tool remedy should only need to be performed once.
Instructions:
Probe Rod
1.

Unscrew the ‘measuring point’ end (A) from the base of the dial gauge.

2.

Apply one drop of blue Loctite® to the threaded end of the ‘measuring point’.

3.

Reinstall the ‘measuring point’ end back onto the dial gauge finger tight.

4.

Fully insert the dial gauge into the probe rod.

5.

Secure the gauge to the probe rod by tightening the locking wing nut by hand.

6.

Test gauge operation by pressing the lower bar of the probe rod inward and
verify the gauge readings correspond with the movement

IT IS NOT NECESSARY TO CALIBATE THE SST
BEFORE EVERY TEST. Only perform the
calibration if the gauges read out of spec.
