Racket After New Clutch Install

Team,

Recently I installed a new clutch kit, flywheel, and rear main seal on my
2016 Tacoma 2.7L 4x4.

Within 1000 miles, I began to notice an intermittent racket when I came to a stop, shifted into neutral, then let off the clutch pedal and reengaging the clutch. I also hear it when driving slow next to close objects that allow the sound to echo back, such as cars, fences, buildings, and some curbs.

The racket stops when I depress the clutch pedal and release the clutch. Reengaging the clutch makes it come back.

It’s really noticeable when my A/C is running. Each time the A/C compressor kicks on, the racket is at its worse.

I made a couple videos to listen to. They’re posted on YouTube.
(if there’s a more efficient, effective, or easier method to share videos, please let me know)

Any insight before I tear back into it will be greatly appreciated!

 

Sadly I have never been able to watch anything on You Tube.


When the transmission was out did you never feel how the transmission input bearing felt?

What brand Clutch kit some really bad made in China bearings. Very Hit or miss quality!

Did you knock the clutch release bearing off center installing the transmission.

 

i think you need to adjust the clutch engagement. sounds like it's not fully disengaging.

 

I purchased and installed the following kit and flywheel. It included release and pilot bearings, disc and pressure plate. I took extra care in further packing the bearings too.

I’m leaning against it being the release bearing, but will troubleshoot it to make sure.

Now, I hate to admit this, but I’m sure I pulled a rookie mistake when doing this job. I had a heck of a time separating the bell housing from the engine. Obviously I didn’t have it aligned and supported axially, causing the input shaft to bind up. A few times I’m certain the entire weight of the transmission and transfer case were being supported by only the input shaft stuck into the clutch assembly.

I’d like to know all the potential ramifications of allowing that to happen.

Mating them back together went very smoothly.

Based on that, I’m worried about the input shaft bearing on transmission side, or worse yet, the thrust bearing on crank shaft.

Regardless, I will just have to drop the transmission again and start from the clutch out.

 

First just why did you pack sealed bearings ??

A very cheap clutch kit of unknown quality.

You had no support under the transmission while attempting to remove it?

The alignment pins tend to be seized and require some work to get things to slide apart.

Good Luck!

 

Oh yes, the alignment pins! That makes me feel somewhat better knowing that perhaps they too were supporting the weight when everything was dangling off the back of the engine. This happened twice and only for a matter of mere seconds each time.

I was well equipped with a 1-ton hydraulic transmission floor jack with fore and aft tilt. I used two ratchet straps to secure the jack and transmission together. They’d become one. But when slowly lowering, constantly adjusting the tilt to accommodate, the front wheels of the jack lifted off the floor. The tilt knob, which turns a screw on the aft end, was obstructed and in contact with the transmission. I raised it back up and loosened my straps. Some time later after wrestling this thing, lowering the jack again, all contact was lost with the transmission. I immediately raised it back up. This happened twice.

As for packing the bearings, I agree with you on the pilot bearing. But without tampering with the seals, using just my thumb to plug the center, I forced it into a cap filled with grease. Grease flowed internally through the bearings and out the top.

It’d been strongly suggested that I pack the release bearing. As far as I could tell it was sealed on one side.

Why, you ask? For thoroughness. To eliminate any question in my mind that there was good and ample grease within those bearings.
