Pebbles The 64 Corvair Monza Converible

[unclejam]

This is Pebbles my 64 Corvair Project.

Theres a Good bit of work ahead of me. The Carbs are getting rebuilt as well as the starter, pulling the Drivetrain in the next couple of weeks to replace the clutch and flexplate as well as seals and any leaky gaskets. Fun times ahead for sure

Looks like a pretty solid start though. Good job!

The red and white seats are a custom job and pretty cool. I like the idea of 4 spoke mags on 4 bolt wheels.

Hmmmm. Broken starter snout. "Replacing clutch and flexplate" (flexplate ?). Make sure you get the correct pressure plate bolts. They aren't regular bolts and help to center the pressure plate on the flywheel. Dennis

I noticed the broken starter nose. Yes for awhile Clark's was selling the INCORRECT pressure plate to flywheel bolts. Hopefully they have corrected this. I got the ones with the correct shoulder from Ray Sedman (American Pi Corvair) and they were made by ARP. Good quality.

It looks like someone restored this car a long time ago and then it was left out, maybe due to the broken starter. If the body is solid it is a good project. Check to see if the 64 suspension and engine is in it. If so a great find!!!

It could also be a loose flywheel rivets.

Welcome to the Corvair Forum!

Hello from Tacoma Washington! Just Purchased a 64 Corvair Monza this past weekend as a project. Starting a Project thread to document the journey but here are some pics of Pebbles for good faith.

Based on your naming scheme, a project report title slide occurred to me...

It looks like this Corvair received some loving attention before it lost its way. Could you post a picture of the engine compartment? Also, could you tell us a little more about yourself, your experience as a DIY mechanic, and how you got interested in Corvairs? Knowing more about your background and mechanical experience will help members of the Corvair Forum as we offer comments and suggestions. Looking forward to your effort to bring this nice Corvair back to life!

Started working on the brakes today, Drums are too far gone, so a complete replacement of the brakes are due from master cylinder, lines, and everything else.

As far as myself, I'm a bit of a old car nut, Pebbles makes the 3rd project in the pipeline right now. There's Fred, the 61 Oldsmobile Super 88 Holiday, Pebbles the 64 Corvair Monza Convertible, and Wilma the 78 Triumph Spitfire. Been working on cars since I was 15, 33 now. Anywho here's a pic of the engine compartment. I'll be back once parts are here and {I have a day to install them. Have a great weekend!

Missing Harmonic Balancer on Pebbles

Corvair Harmonic Balancer/Oil cooler Replacement.



Page 4 of the attached CORSA Corvair Technical Guide 1+2 - Corvair Code Numbers Will help you to verify the actual engine type in Pebbles. In 1964 and later Corvairs GM engineers switched to the use of a HARMONIC BALANCER to protect the long-stroke crankshaft that was introduced in 1964 to increase the engine dispacement to 164 CID. The exception was found in the lowest horsepower engines, in which GM compromised to save costs by using a solid crankshaft pulley. The three-piece harmonic balancer does eventually wear out, and owners smetimes try to save money by substituting a cheaper solid crankshaft pulley. To protect your crankshaft you may want to consider purchasing a new harmonic balancer for Pebbles.

If I'm decoding it properly It's a 110.

T0417YN

T = Tonawanda, New York (GM Tonawanda Engine Plant)
http://media.gm.com/media/us/en/gm/comp ... wanda.html
0417 = Engine manufacturing date (month and date). April 17th. (If it is the original engine, probably 04/17/1964)
"YN" is from 1961-1964 (No year is included in the date stamp, unfortunately).
YN
1961: 98hp — 145 CID (Cubic Inch Displacement), 9:1 Compression Ratio, with Manual Transmission — Corvair 500, 700 and 900 Monza only.
1962-1963: 102hp — 145 CID (Cubic Inch Displacement), 9:1 Compression Ratio, with Manual Transmission — Corvair 500, 700 and 900 Monza only.
1964: 110hp — 164 CID (Cubic Inch Displacement), 9:1 Compression Ratio, with Manual Transmission — Corvair 500, 700 and 900 Monza only.

Your engine has the type of cast pulley only found on 1964 and later engines (although it would fit on any model year engine). Assuming that all other evidence indicates that it is still the original engine, and that it is a 110 hp engine, someone apparently substituted a cheaper cast pulley in the past to replace a failed harmonic balancer, which is more expensive. GM also cut costs with their basic 95 hp engine by using this pulley on the base engine, but engineers were convinced that the long-stroke 164 CID crankshaft in engines rated at 110hp and above demanded the use of a harmonic balancer to protect the crankshaft from developing cracks or stress fractures. You will have to decide whether or not to replace this solid pulley with a correct harmonic balancer.

A used harmonic balancer, froma source like The Corvair Ranch in Gettysburg, Pennsylvania https://corvairranch.com/ might be considered, but all 3-piece harmonic balancers eventually fail over the years, as the "press-fit" rubber component that holds the outer ring to the center hub decays and the outer ring begins to slip. There is no way to know how much life is left in a used harmonic balancer that shows no evidence of slippage. If you wish to install a new harmonic balancer...
