LUBRICATION POINTS





DISASSEMBLY SERVICE POINT



<<A>> PTJ CASE REMOVAL


caution Pay attention to the spider assembly roller because it may be disconnected easily.

<<B>> PTJ BOOT REMOVAL


1.Wipe off the grease on the shaft spline.
2.If the PTJ boot is reused, protect the shaft spline area with a tape from damage in pulling out the boot.

ASSEMBLY SERVICE POINT



>>A<< DYNAMIC DAMPER/DAMPER BAND INSTALLATION



1.
caution There should be no grease adhered to the rubber part of the dynamic damper.
Install the dynamic damper in the position (A) shown in the figure.
A:
231 ± 3 mm <LH (4N1)>
312 ± 3 mm <RH (4B1, 4J1)>
2.Secure the damper band.
3.Wrap plastic tape around the shaft spline, and then install the PTJ boot band (small) and PTJ boot.

>>B<< PTJ BOOT INSTALLATION


Apply a tape to the shaft spline area, and then incorporate the PTJ boot.

>>C<< SPIDER ASSEMBLY/PTJ CASE INSTALLATION


caution
  • Special grease is used for the joint. Do not mix the new and previous types of grease or different types of grease.
  • When the spider assembly is cleaned, apply the specified grease carefully more than usual.
1.Fill the specified grease fully into the clearance between the spider shaft of the spider assembly and the roller.
Specified grease: Repair kit grease

2.Install the spider assembly to the shaft of the spline area from the bevelling side.

3.Insert the driveshaft into the PTJ case after filling the specified grease to the PTJ case, and then fill the grease again.
Specified grease: Repair kit grease
Application amount:
210 ± 10 g <4B1-LH, 4J1-LH>
200 ± 10 g <4B1-RH, 4J1-RH>
255 ± 10 g <4N1 (M/T), 4N1 (A/T)-RH>
245 ± 10 g <4N1 (A/T)-LH>
note When using the repair kit grease, fill the half of the grease into the joint and the other half into the boot as a guideline, and consume the grease completely.

>>D<< PTJ BOOT BAND (SMALL)/PTJ BOOT BAND (LARGE) INSTALLATION



Adjust the distance between the boot bands to the standard value to make the air volume inside the PTJ boot to the specified value, then be sure to tighten the PTJ boot band (large) and PTJ boot band (small).
Standard value:
85 ± 3 mm <4B1, 4J1>
85 ± 3 mm <4N1>
