Hey guys, have a question for you all about the essentric shaft bolt which connects from the front engine pulley. I remember seeing somewhere on this forum a locking plate for an FC that fits over the top of the essentric shaft bolt that actually holds the bolt in place on top of the drive pulley. What I was wondering was was if that locking plate came standard for FDs. I had some problems in the past where my essentric shaft bolt was not torqued on enough and I had to break into the front of the car and torque the bolt down with a heavy duty torque wrench (torqued to 195 lb-ft). I don't have that locking plate on the front of my drive pulley and was wondering if this was a stock part that came with the FD. I can't find the post that had the plate for the life of me, so sorry I can't post a pic of the locking plate, but do any of you guys know if that locking plate came standard on the FDs or were the bolts just torqued on to spec?

 

The eccentric shaft bolt should have been torqued on during engine assembly. This would have been done with a stop bar bolted to the fly wheel.
To do this with the engine in the car, put the car in gear, set the brake or better yet, have a friend step on the brakes and torque away.

 

Its suppossed to be torqued between 290-360 ib-ft according to the manual... gonna need a bigger torque wrench, or calculate the length of a braker bar and your weight... have fun

 

To answer your question ..No the stopper is not standard equipment on the FD. I have one on my engine. however i believe that XS put it on when they did their thing a long time ago.

It can't hurt to have it on since all that is required to install is pull off 2 bolts on the pulley and install the brace/stopper. Pretty straight forward. But if the bolt was torqued properly on assembly it should not be a problem.

 

you sure it's 290 to 360? The copy of the shop manual I have says 180 to 200 lb-ft.

 

yeah, the first time I found the problem I took it to a shop and they put it back in, but did not dead stop the rotation of the engine when they were putting it back on, so the bolt backed out, then I basically did it myself: put the car in 5th, then had someone step on the brake and toqued it to 195lb-ft.

 

yeah, I think it is supposed to be 180-200lb-ft, just checked a couple of different install manuals for pulley installs and they all say 180 to 200 and just double checked the shop manual and it says 180-200 as well.

 

My '95 has this locking plate.

the front bolt 190 ft. lbs. the rear nut 300 ft. lbs. all inthebookRON

 

Seems a lot of the 89-95 engines have the plate, but most do not. From what I can tell a lot of remans came with it. I've never noticed a rhyme or reason to it, really.

With the torque on that thing (my 600ft-lb gun usually has trouble with them) plus the loctite on the threads, you really dont need it.
