Strange noise

Post by ronenbetzalel »

I have a question today while driving the car I notice a rattling noice I drove back home and look under. Cont don’t find where it come from but it look like it’s coming from the fly wheel area you mostly hear it in low rpm.
I disconnect the belt from the fan and from the AC just to make sure it’s not the fan.
I attached two video.
Any idea ?

Is the car a stick shift or automatic?

:wave: :welcome2: :wave: Welcome, Ronen, to the Corvair Forum!


Air conditioned Corvairs are pretty rare. Does your A/C work? I hope you will post some photographs of your Corvair.
AirVair Group wrote:Chevrolet took another big gamble when they developed and offered the Air Conditioning system for the Corvair. Unusual design was required by the need for sufficient air movement thru the condenser and the result was a very strange looking installation, to say the least.

When the Corvair was first made available with A/C in the Spring of 1961 the base price of a Monza Club Coupe was $2201.00 So the Air Conditioning added around 16% to the cost of the car!! About 1% of the buyers stepped up - about 3000 Air 'Vairs in 1961. The percentage increased in 1962 to a whopping 2.5% ! This was the Corvair’s best sales year with 306,000 cars sold, so around 7,650 Air 'Vairs were created. 1963 was also a great year for the Corvair with over 254,000 made and again about 2.5% or 6641 had cool drivers and passengers.

1964 saw some major mechanical changes to the Corvair with the engine displacement stroked to 164 cu. in. with the result of about a 20% power gain and the rear suspension revised to improve ride and handling. But Americans were used to a New Look every year, and Corvairs were in there fourth year with only minor trim variations to tell the cars apart - Why buy a new car when your neighbors can't tell?? As a result, another 50,000 drop in sales to under 200,000 but the increased power brought out more A/C buyers at 3.20% produced, 6401 more cool ones added to the pool...

If your Corvair has a manual transmission, and it rattles loudly from the clutch area while idling in Neutral, does the rattling sound stop when you start to depress the clutch pedal? If you have a loose, noisy flywheel, the noise will often stop when you press the clutch pedal enough to bring the throwout bearing into contact with the clutch diaphragm spring in the clutch pressure plate. The physical contact with the throwout bearing can dampen the vibration and loose flywheel and will often silence te rattling sound. The rattling sound will return when you take your foot off of the clutch pedal.
Clark's Corvair Parts wrote:We offer REBUILT STOCK FLYWHEELS and SOLID STEEL FLYWHEELS. Be sure to read about each type before ordering. We also offer bolt kits to rebuild your own. Flat? Recessed? See page 108! Bad Flywheels: Stock flywheels are riveted together. They are usually good for 50,000 to 110,000 miles, then they start to rattle and later also vibrate badly. If yours has over 75,000 miles and you are replacing a clutch disc, I would replace the flywheel. Be sure to replace all seaIs and gaskets
:link: http://www.corvair.com/user-cgi/catalog ... w_page=109

Unfortunately, the "fix" requires removing the engine and transaxle from the vehicle, separating the engine from the transaxle, and performing a clutch overhaul (replacing all worn parts — not just the worn flywheel).

If you determine that a replacement clutch is in your future and you plan to do it yourself, check back with us for advice before you begin the project. If you are a member of a local CORSA (Corvair society of America) club chapter, you may be able to recruit some assistance there to make the job easier and safer.


:dontknow: I would like to encourage you to expand on your post and tell us more about yourself, as well as about your Corvair. Your personal assessment of your mechanical skills and abilities helps a lot. Members of the Corvair Forum love to be helpful in assisting other Corvair owners with technical support and advice, but it helps a lot if we have some understanding of your technical background and mechanical abilities, your Corvair-related knowledge, etc. Helping us to know more about you, your Corvair, and you plans for your Corvair will help us to write comments to you that are tailored to your needs and experience. Knowing where you live may also help, as your location may suggest some possibilities or solutions.

The link below will provide you with a list of useful websites that are Corvair-related. Some of the links will lead you to an extensive technical library that will allow you to download shop manuals and other technical references in Adobe Reader (.pdf) format at no cost. There is also a link that will help you to locate nearby CORSA (Corvair Society of America) club chapters. While the Corvair Forum can be very helpful as you work on your Corvair, having local friends and contacts in your region who are knowledgeable about the Corvair can also be very helpful. These family-friendly CORSA club chapters often offer picnics, group scenic drives, technical training and assistance, car shows, and competition events that can greatly enhance your enjoyment of Corvair ownership. You will also find a list of essential Corvair parts suppliers.

Thank you for the quick replay.

I give you a bit background about me and the car.
I live in northern NJ.
I bought the car about 2 months ago
It had two owners - one from 1964 to 1998 and the second from 1998 to 2019.
It’s a 2 door with 54k original miles and factory AC. It’s 110hp monza 900 and it’s a 2 speed power glide

I love the car and I did some basic maintenance on it - check plugs, wires, oil pan seal, valve cover seal, I changed 6 push rod tube o rings, two new carburetors, 4 new tiers, fixes and change all heater ducts - needed a good heat in NJ - I changed the gas tank and the sander and the steering wheel stabilizer bar bushing

I love the car and drive it every day

Back to the strange noise - it’s happening while in drive or in neutral and it’s mostly noticeable in low rpm.
I can’t tell where exactly it’s coming from but it’s from the area of the back where the engine meet the transmission


Here are some picture of the car

By the way I met Jeff from corvair range - he is a great guy and helped me a lot - thank you Jeff

Check to make sure the three bolts holding the trans. flex plate to the torque converter are tight.

Since you have an automatic transmission, I wonder if the flex plate that secures the crankshaft to the transmission torque converter might be loose or missing a bolt?

Image

Steps 3 an 4 below indicates that all three bolts should be hand-started prior to torquing. I believe the bolts should be long enough to reach the torque converter.

Image

Image

The flex plate has a convex and a concave side. Installation is addressed in the link to the Corvair Center...

You find the craziest things on cars other people have worked on. I thought I would find the flex plate on upside down because the bolts were too far forward when I was taking it apart but I was wrong. Never would have guessed.

ImageImage
According to the Clark's Corvair Parts online catalog, the flex plates are different for 1960-1963 (145 CI) and 1964-1969 (164 CI) engines, with a slightly deeper (.375) concave offset for the 145 CI engines, and a .325 concave offset for the 164 CI engines.

This is what I would do first. If these are good I would guess an internal differential issue from listening to the video but can not hear things like this well from a distance:)

Don't forget a broken flex plate. I've had this quite a bit and it continues to get worse until it sounds like a broken crank. The bell housing is also often broken.

You can get to the access panel shown in Brad's post without engine removal. You may have to remove front shroud sheet metal.

You can inspect the torque converter flex plate attachment bolts via the metal access plate shown on the bell housing. Some engine sheet metal at the front of the engine will have t be removed to expose the cover plate on the aluminum bell housing.

You can also see a portion of the torque converter and the starter ring gear via a large opening on the lower right side of the bell housing.


NOTE: DO NOT CLIMB UNDER THE CAR UNLESS IT IS PROPERLY SUPPORTED ON FIRM GROUND (I.E. CONCRETE OR ASPHALT PAVEMENT) BY JACK STANDS. DO NOT TRUST A HYDRAULIC JACK OR MECHANICAL SCISSORS JACK TO SUPPORT THE CAR! NEVER USE CONCRETE CINDER BLOCKS OR SIMILAR MATERIALS TO HOLD THE CAR UP IN THE AIR FOR MAINTENANCE.

You will need to download the complete 1961 Corvair Shop Manual and the 1964 Supplements.

The bolts that hold the flex plate to the torque converter (3) can be accessed, inspected, and tightened via the metal access plate at the top of the aluminum bell housing. if one or more bolts are missing...

Thank you brad for the information
I was planing to drive the car on Saturday 12/7 to the monthly meeting for the first time. I guess it’s not safe to drive it like this. I will probably will go to meet those member and look for help with a local mechanic that know that car. My guy is not familiar with corvair.



I will try to get access to those bolts and check them

I have attached two images.
This is the cover that need to be removed ?
I guess I need to check it from the top of the engine (not from under the car )

Thank you
