Clean and paint

Since today was sunny and somewhat warm, I decided to clean and paint some parts.

Lower axle bumper housings

Leaf springs

Sway bar and hardware

Rear caliper brackets

Since the rear end will serviced, no point in painting it, I'll do that once I get it back. I looked up the casting numbers. It has a posi center unit made February 20th 1962

Shocking Progress

Moving along on my punch list..... I started on the suspension. I expected the shocks would be bad, siting in the same position for 15 years has a tendency to cause issues. My experience has also shown me that removing the shocks can be a pain, the nuts stick causing the shaft to spin, not loosen. As I lay under the 55 ready to remove the nut, I said a prayer and hoped for the best.

Lucky for me, the bolts came out easily. Once I removed all four, I tested them by compressing the shocks. What should have been difficult was very easy, no resistance! Here they are, five minutes after I compressed them, no movement back to extension......DOA!

Hello new shocks!!!

Sway bar links....

I replaced the rear sway bar links with a more robust option with polyurethane bushings. I will be doing the same on the front sway bar.

I plan to have the rear end inspected to make sure it is in good condition and have any issues corrected. I hope, since the transmission was fine, that the same can be said for the rear end... Fingers crossed. I am also going to take the opportunity to have the drive line upgraded with  a beefier drive shaft, transmission output shaft, and rear end pinion yoke. My wife's Acadia, comes in handy !!

I was going to replace the gas tank sending unit, but two stripped screws brought that to a screeching stop. Once I get a set of EZ outs, I will try again.

With the drive line, rear end, shocks, and springs removed, their is plenty of room to inspect the undercarriage for issues and to do some TLC and cleaning.

The body has held up very well, the paint is great, but there are a few little issues. One area, is around the driver's side mirror. The paint has discolored around the gasket, not sure what caused it and if it can be corrected without paint work. I don't have plans to correct that now, as my goal is to get the 55 reliably running so it can be enjoyed!!

Birthday!!!

My schedule has kept me away from the 55 for a few weeks, so i am really excited to get back to work.

I am not a big social media nut, but i do use facebook and every once in a while it pays off big.  I belong to several classic chevy groups and one day i caught a post by another 55 owner that lead to some good info regarding my 55.  The person posted the birth date of his 55. That got me to thinking, could i find out the day my 55 was built??

I was surprised how quickly i was able to locate production documents for 1955. That, coupled with decoding my VIN number, i was able to determine the following: My 55 was built on Friday, May 20th 1955 sometime in the morning at the Baltimore Maryland plant.


Decoded VIN: B=55, C=B, D=133571

 

 



Production sheet:

The last VIN on Thursday the 19th was 133560 and the last VIN on the 20th was 134349. That means they produced 789   55 chevys on Friday and since my VIN would have been the 11th car produced that day, it is safe to guess it would have been early in the morning.  What is really cool is, the document also shows the days the plant was down for repairs or to change out tooling....

Drive train and suspension

Progressing.......

As you know, if you have been following my posts, I pulled the trans and was going to have it gone over.  I dropped off the trans to a local transmission specialist for a thorough inspection, I picked up the trans Friday and it passed with flying colors.  Some slight wear on the reverse gear, but that is normal and it was well within spec. They noted that who ever last worked on it, used RTV and not gaskets.... The shop corrected that, so now it looks a lot better and will not leak.  They cleaned it up as well.

The next large item to address is the rear end.  Since the rear end was rebuilt the same time as the trans, I am even more optimistic that it wont need any repairs, maybe new axle bearings, but even that isn't a big deal.  I have been spending a lot of tile playing detective, under the car, as I go over it from front to back noticing items either missing or in need or repair or replacement.  It pays to have an assembly manual or the link to an online version.  The assembly manual shows where everything should be and how it is put together. 

When I was driving the car (late 90's), I remember when the car hit bumps and the suspension was really working, I would always hear a loud noise, sounded like the suspension was bottoming out.  That has been on my mental checklist to figure out.  As I was looking over the suspension and checking suspension parts in my parts catalogs (Danchuk and Lutty's chevy) I noticed they listed upper and lower rear axle bushings.  I consulted the assembly manual to see the drawing of their location, I quickly realized I was missing them.  The noise I always heard was the rear axle hitting the underside of the frame.  The bushing prevent that from happening!

If you want to take a glimpse into how a 1955 Chevy Bel Air is put together, follow this link, it is the full shop assembly manual.  It is an absolute must have when restoring one of them.  Consider it the cars bible!!!

The bumpers and their brackets are missing from my rear end.  The bumpers should be on either end of the axels next to the "U" bolts. The "U" bolts hold the bumper brackets to the axle.

 

I am also going to replace the sway bar links that connect from the frame to the ends of the sway bar.

Mine are a little tired....

When I test fit the rear break calipers (92 Chevy S-10) I realized that the disc brake conversion kit required a little hump in the casting to be ground flat.  That only took be a few minutes with a grinder
