Is the oil pressure good (no warning light)?

Can you post a video of the noise?

I guess you have not read the TC installation manual then, dandan...

No, I just know that the alignment pin procedure was dumped because it made no sense.

The gerotor in the pump must be aligned with the crankshaft, not the cam plate or crankcase.

If the pins are used they will force the pump body into a certain spot when the fat part of the pin snugs into position, this may not be the best position for the body.

Snugging the OEM bolts while rotating the crankshaft will allow the shaft to move the body into the proper position without being in a bind.

I have not only read the service manual, I also understand what is being accomplished, and I have done the task numerous times.

Also, you can refrain from the childish name calling.

I opened the cam cover and the tensioners look fine. I'm not hearing the noise so much with just idling like I did while riding but maybe I'm just being paranoid in thinking that there's something wrong.
I didn't see a way to upload the video here so put it in Google Drive.

Did you use the service manual procedure when you installed the pump?

Now that you have it open again. Just a thought for you - Maybe pull the plugs and do a rotation check and see if there is anything that sounds or looks not quite right.
Easy enough, and its right there.

Again - like always - you did not read or follow the engineers design for reinstallation. Yes, the engineers - the smart ones that know how things are to be done, over a wahttobe back yarder. That's ok - I know, you are right and the engineers are wrong.

Back side one hasn't fallen apart has it? Hard to see it.


I don't really hear anything abnormal on your .mov audio. Sure not a chain on a missing tensioner pad.

It seems like we have to "threads" going on here now.
For the entire procedure that I did when changing the tensioners and installing new cam bearings, I was following the manual along with a bunch of videos.
I think the conversation here about the oil pump came out of someone else's post, not mine, but figured I clarify the use of the manual for my work.

The sound clip you posted seemed normal to me, there was no loud clatter.

Is the oil pressure ok?

Sometimes when people reassemble a cam chest and there is a clatter or low oil pressure it is due to an o ring that dropped out of place during assembly...

I don't have an oil gauge but no lights on either so assuming it's ok
