Just installed my jdm 4.7 final drive in my tranny for my trip to Expo. Started car up to hear a loud clicking. Sounds almost like a rod knock. It is coming from the tranny. I just replaced clutch and flywheel also. The input shaft is not bound up and spins freely. I just pullled it from the car and opened it up to find everything looking just fine. Noise goes away when you push clutch pedal in and all gears shift smooth. Dont want to drive it this way.

Please help, only 3 days till I leave for Expo and need her fixed!!

Any ideas??? I am stumped, searched all over with no results

 

"sounds" like a throwout bearing kind of sound to me

 

I thought so too, but I just installed a brand new act clutch kit and JUN flywheel

The noise takes about 2-3 seconds to go away like the internals of the tranny are slowing to a stop and it clicks/knocks till it stops turning after I press the clutch pedal in

 

my older civic did the same thing.

It went years with no problems.

My itr kinda does the same thing, just not as much of a pronounced "ticking" like yours

I would also guess throwout bearing if you didn't just replace it.

hmmmm

 

Yes, the throw out bearing was replaced with new clutch. This is a loud click/knock. It sounds alot like a rod knock. I did the screw driver to ear test and it sounds like its in the bell housing. My wife could hear it from the house and we have a detached 24x24 shop 50 ft away. I would really like to rock this FD at Expo......

Headin off to work

 

what type of clutch did you put in, i've heard perfectly healthy ORC kits make some terrible noises

 

did you measure and use the proper shims as described in the Helm manual? whenever you swap shafts or the diff, or swap everything into a new case, you should check the shims/clearances.

That sounds like the input shaft bearing. If you have the tranny open just go ahead and replace it as well as the rubber seal behind it. How many miles do you have on the tranny?

 

could be your differential shimming clearance. i found this out after installing, disassembling, and reinstalling my trans 9 times. biggest pain in the *** as far as transmission work.

if all the gears look clean, and no sign of chipping, and all bearings move freely and no chips on bearings, and if your clutch arm is also correctly put in and all gears shift freely by hand. and when you put the trans back together and all snap rings actually snap in, and if you correctly torque the shaft nut, then the only other thing i can think of is the shims for the differential. ????

^^god, i feel your pain.....

But I agree with shoe

 

ITR-2001 just started having that problem too. They're gonna pull the tranny out to inspect it. I'll post more info or have him post what they find.

The lsd wasnt changed, just the ring gear. Im out to the garage to screw with it some more, no signs of hope yet

 

Problem found!!!

Jdm final drive first gear had 2 teeth(main syn gear) that were hit/gouged over very lightly causing slight binding when it came in contact with the input shaft. Took my snap-on da sander with 120 grit pad and slowly deburred it and is as good as new.



See ya at Expo

 

Awesome to hear. See joo at expo!!!

 

baddass, so this year maybe we can drink them beers.....and you can check out the new paintjob and motor

 

nemesis, bring your FC/C JUST in case, but i might not need it as well either after i get a ride with your bad *** K
