Coupler end play?

(1/3) > >>

tinbanger:
Well I pulled the trans out for a yearly look. My coupler was pushed 1/4 " into support.I was running 3/16" end play. The motor plate is not bent. My question is how much end play is to much? Any info would be a greet help.

Mrs Esterhouse:
1) T
HE COUPLER MUST BE LONG ENOUGH THAT THE GROUND SURFACE IS COMPLETELY THROUGH THE BUSHING IN THE TRANSMISSION TAIL HOUS
-
ING
.  I
F THIS CANNOT BE OBTAINED IT WILL BE NECESSARY TO GO TO A DRIVE SHAFT WITH
4
COUPLERS AND A SPLINED DRIVESHAFT
.
2) I
N ORDER TO KEEP THE COUPLER PROPERLY ENGAGED IN DIFFERENTIAL COUPLER IT IS NECESSARY TO HAVE A SPACER INSERTED IN TO THE
COUPLER BEFORE INSTALLING IN THE TRANSMISSION
.  T
HE SPACER NEEDS TO BE A LENGTH THAT WILL ALLOW APPROXIMATELY
1/8”
OF MOVEMENT
OF THE COUPLER IN AND OUT
.  T
HIS MOVEMENT IS NECESSARY BECAUSE OF NORMAL MOVEMENT OF THE CHASSIS
. T
HE SPACER CAN BE MADE
FROM ALUMINUM
,
HARDWOOD OR PLASTIC
(
NOT SUPPLIED BY
M/W)
ROUND MATERIAL
.
3) A
LIGNMENT IS CRITICAL
,
ANY ABNORMAL WEAR IS A SIGN THAT THE ENGINE
-
TRANSMISSION
-
REAR PINION CENTERLINE ARE NOT PERFECTLY
ALIGNED
.  C
OUPLERS ARE NOT DESIGNED TO TAKE ANY MISALIGNMENT
.

You can go back and edit your post at anytime to clean it up.

If I put a spacer in front of the coupler would that remove end play ? I had 3/16 play for flex.
