Loud and scary noises coming from my 440...

[Grabinov911]

In his first post he eliminated the water pump. I had a friend spin a bearing yrs ago in a small block chevy and it made a odd whinning noise. Man I hate it for you. I know these problems can cause a person a lot of stress. I seen one guy put bolts that were to long in the crank pulleys on a hemi one time and the bolts were hitting the timing chain cover but you have already had the timing chain cover off.

I wasn't going to say it, but now that it's been mentioned: I don't remember hearing you say you had the TIMING COVER off as a test yet. I have been putting a new motor together / watching it go together over the past months and was surprised by how close the cam parts are to the timing chain cover. Any chance you have a cam bolt rubbing against the timing chain cover? Although I'll admit that's not the sound I'd expect from that problem...

Sounds like you have tried just about everything external mhow about something metal rubbing on the harmonic balancer lioke the timong index pointer just a thought because you said you removed all the belts and it still made the noise.

Also one of the first things i looked at. Its all good.

Looks like im gonna pull the pump off after i inspect everything one last time. I dont want to put it back together till i know for sure whats causing it.

Well then it must have a fan spinning by mouse and wheel lmao maybe your motor is just that a "screamer"! I listen to that sound over and over and could swear it sounds like a fly wheel hitting, the way it sounds spinning and then it just stops when you kill it. The problem is in the video which is all we have to go on shows your water pump hooked up, do you have other vids with out it? or have you cranked the engine with out starting it or did you rev it to see if it goes up and down with the rpm's? don;t thing I saw an answer on that one yet?

I took the video after weeks of trouble shooting. Ive run the motor with everything off that can be off and still run safely. The entire front end of the motor has been off. Its not the water pump! It does sound like the flywheel/flexplate. It has that ringing to it when it shuts down. But i havent found any interferance or damage. I think ill open up the trans this week and have a look inside. Ill post some more pics to see if anyone can find anything amiss.

sounds like the starter is running and disengaging at end of vid un hook the starter sig wire and use a remote switch to start and see if the wire has power after the engine is running, had a car that was back feeding in the elec system after running and had my starter engaged

 

[BeastlyBirdie]

He said he watched the starter disengage. And its not the water pump, either. Nor a belt. Nor a vacuum leak. All this has been covered in earlier posts. It is great that everyone wants to help, but, at least read the previous posts.

 

['67Satellite]

A couple shots of the flexplate. I havent messed with this since the rebuild, so it ran fine in the Satellite. Dont see it being a problem.

Tape a plastic paint can cap over the end of the trans tailshaft and fill it to operating level. Fluid in the lines doesnt mean it is pumping properly. I think running it low has damaged it.

Ever hear a power steering pump low on fluid. Sounds similar dont it.

Well that's why i want to get into the trans. The torque converter was filled when i pulled it all last night, so that's not running dry. And my dipstick is reading a little over full when the trans is off and cold. Obviously, i don't feel comfortable warming things up and checking it properly. But it seems like there's ample fluid in it. I guess i should probably be around 8.5 quarts with my 11 inch converter and a deep trans pan, i have pretty close to that drained out of it.

 

[Meep-Meep]

Do you know anything about that tranny and converter? Were they both running with the other engine? If those are new parts to this conversion then count the splines on the tranny input shaft and the corresponding splines in the converter. The old input is a 19 spline (up to maybe 65 or 66) and the later is the 24 spline, which is slightly larger. Check to see if you have a 24 spline converter on a 19 spline shaft. This may be completely off the wall but as long as we are looking for the proverbial needle in a haystack might as well check.

I like this one. I looked at the pictures you posted of the transmission input shaft and there does appear to possibly be a sizable groove on it. Definitely worth investigating.

I would say if it ran good in the previous car and you used all the same components it's got something to do with how you installed everything in the new car. It sounds like a blower car.

Yes, all the components on this motor/trans are the same that ran well in my Satellite last year. So I agree, i must have messed something up installing them.

As far as the grove on my input shaft, i'm not sure. I guess i never noticed it before, but then again i don't ever remember really looking at it. When i get off work today, i'm going to drain the torque converter the rest of the way and see if there's any damage to the inside of it. I'm also looking into exactly what parts i'll need to replace when i pull of the front pump. I really think the problem is in there. As has been said previously, if it was in the motor, i don't think it would still be spinning right now.

 

['67Satellite]

Well, after my son goes to sleep ill drop the pan and see what it looks like inside. Ill post a few more pictures after i do.

 

[BeastlyBirdie]

If its the groove I think you guys are talking about, its normal. About half inch or so from end of shaft?

Yea, it looks intentional.

 

['67Satellite]

Update. I pulled the pan off the transmission and found nothing out of the ordinary. Very very small glitter in the fluid, but nothing that I think is bad. I put the torque converter back on just to see what it feels like now that everything's out of the car. Spinning the torque converter over by hand was easy, and i could here fluid inside moving around. I was engaged in the pump for sure, and i couldn't hear any squealing or anything "bad". I spun the tail shaft in every gear but park (obviously), and had a squeaking inside the trans. Obviously i'm spinning it very slowly and for short bursts. But, could i be on to something here? Or is some squeakiness to be expected?

Remember, whatever's making that horrible noise when the motor is running, also does it in PARK. So for this to be the problem, whatever is squeaking would have to also be "engaged" in PARK. Mystery...

The slight squeaking while turning the output shaft by hand is normal.

I suppose if this tranny, converter and engine were all running as a unit before without noise then you need to piece this together from the time you shut it off to the time it restarted in the new car. And I know you have been - just gotta find the devil's hiding place. Pretty much rules out my mis-match spline theory but it only takes a minute to count them to see if they match.

Well I pulled the trans apart as far as i can without a slide hammer. Everything seemed like it was in really good shape. The bands look new, and from what i can see the surface on the bells looks nice. No grooves or anything. The output shaft bearing is really nice too.

But, something i noticed. The servo (i think it's called) between the 2 band tensioners (accumulators?) HAD NO SPRING. I'm sure it's supposed to have a spring, right? I looked everywhere in the garage and in the drip pan. And i'm sure i didn't drop anything. It's just not there. What do you guys think. I'm just looking for every little problem to put blame on. Shooting in the dark, as it were.

Damn, just watched a video on rebuilding these damn things. And they didn't use a spring on there's... Back to the drawing board.
