Ive been putting together the parts for an evetual T-9 conversion to my Xflow. This is the list of stuff I know so far.
Not sure I agree with Burton on the "standard Escort clutch".
On parts, standard 1600 Kent clutch disc is 190mm 7/8" x 20. A T9 was never fitted to Kent 1600 in a Ford road car, but on 2ltr and larger engines using larger clutches.
To adapt the T9 to work with the Kent it only requires two or three things: (1) A 1" spacer between the case and the bell IF the T9 uses the longer input shaft (1x23), and a small bit of the shaft length may need removal. (2) A reduced diamter input shaft sleeve the release bearing slides on so std Escort bearings can be used (with a std Kent pressure plate). (3) A special 190mm 1x23 PPlate, which is an oddity because the 1"x23 discs were larger in diameter for the 2ltr Pintos. Im not sure what vehicles used a 190mm 1x23 but I've only heard of one. Thank Burton for keeping them in stock.
Input shaft tips are same dia so pilot/spigot bearing is common to both.
I believe I have seen a CRB spacer on Burton for the takeup issues.
Here is a more typical CC
Vibration causes, im only sugessing here...
Trans & engine mounts loose,
warped flywheel, chatter/ slipping from contaminated flywheel surface, uneven bellhousing bolt torque, prop shaft U joints bad.
I hope Im helpful here.
