(d) With the center of the sleeve correctly placed between thecrimping jaws, squeeze the crimping tool until either end
comes into contact at the section marked by ªCLOSE HEREº.
HINT: Check to see that the sleeve and wires are still in the
correct position before closing the crimping tool ends with
steady pressure.
(e) Pull the joined wires to either end. Make sure that they are joined firmly by the sleeve.
NOTICE: If the joined wires come loose the splice is de-
fective, so replace the sleeve and repeat the procedure.
(f) Crimp both ends of the sleeve with the crimping tool at the ªINSº position.
4. PROTECT JOINED SECTION Wrap silicon tape around the joins to protect them from water.
HINT:
wBefore starting the operation, throughly wipe dirt and
grease off the sections to be joined.
w If the adhesive surfaces of 2 tapes come in contact, they
will stick together and will not come apart, so do not
remove the backing film except when using the tape.
w Do not let oil and dust, etc., get on the tape surface.
(a) Ready about 100 mm (3.94 in.) of silicon tape (Part No. 08231±00045) and peel off the film.
(b) Stretch the silicon tape until its width is reduced by half.
(c) About 10 mm (0.39 in.) from the end of the pressure contact
sleeve, wrap the silicon tape around the sleeve 3 or more
times while stretching the tape.

wIf the preload is greater than the specification, replace
the spacer.
w If the preload is less than the specification, retighten the
nut 13 NVm (130 kgfVcm, 9 ftVlbf) at a time until the
specified preload is reached.
Maximum torque:
490 N Vm (5,000 kgf Vcm, 362 ft Vlbf)
If the maximum torque is exceeded while retightening the
nut, replace the spacer and repeat the preload procedure.
Do not back off the nut to reduce the preload.
26. CHECK RUNOUT OF DRIVE PINION SHAFT Measure the r unout of the drive pinion shaft at a point 10 mm
(0.39 in.) from the end of the shaft.
Maximum runout:
0.08 mm (0.0031 in.)
