1969 Plymouth Barracuda Restoration
 
 

Before Reassembly

Cleaning Parts

  1. I have a cup style wire brush that goes on a large grinder that I use to clean rust and old paint. This is an industrial grade grinder that I've had for at least 35 yrs. I have found a cleaner at Walmart that works well. It's called Super Clean and comes in a purple spray bottle. You can also but it in a gallon size. It's very high detergent, I recommend latex gloves if you get your hand in it. The gray color on the cover is Eastwood Spray Gray and the black is Rustoleum semi-gloss. If I have heavy rust, I use a product called Extend, made by Loctite. I get the paint on bottle, it also comes in spray. Very good product.

Removing Rust (Chemicals)

  1. Sodium carbonate can be found in the laundry soap aisle of the supermarket. Look for "Washing Soda"; it will probably be on the shelf next to Borax. You can also find it in pool and spa supply stores as "pH Increaser". Read the ingredients on the label to make sure its pure sodium carbonate. Sodium carbonate should be in your garage anyway, since its used to make the electrolyte solution for electrolytic rust removal. I did a rust removal post a long time ago if you want to search the archives, or just Google "electrolytic rust removal". There's a how-to video on the Mopar Mailing List website:

  2. www.moparmailinglist.com

Removing Rust (Wire Wheel)

  1. You will spend hours at the wire wheel cleaning bolts, the battery tray and one of the brackets that holds the front bumper to the frame. The majority of that time was spent on bolts, for the doors, trunk lid hinges, hood hinges, front clip. fenders, etc. Your body guy needs them when he starts assembling the car. Very tedious.


  2. Wipe off all the bolts cleaned up the previous day (they soaked overnight in a rust dissolver).

Media Blasting Cabinet

  1. Consider purchasing a media blasting cabinet to save you time and effort restoring car parts.

De-Rusting Chrome

  1. Oxalic acid, the acid part of Prestone Heavy Duty Radiator Cleaner, (discontinued several years ago) can also be used for de-rusting chrome.

Cleaning Engine Bay

  1. Use simple green and cotton cloth to scrub most of the grease off and finish with Armor all cleaning wipes.

Bolts

  1. If you have issues with bolds and threads, run a tap down the hole after blowing it out with compressed air because there may be dirt or other debris lodged inside there. But as long as you have enough threads to keep it tight, it should be good.

  2. Nathan


  3. Whenever I doubt the correct bolt is in there, I run something thin down the threaded hole to gauge the depth of the hole and compare that to the length of the bolt (minus the thickness of whatever the bolt is holding, of course).


  4. The bolt doesn't have to run all the way to the end of the threaded hole but it should have enough threads for the job. An easier way is to count turns from engagement until the bolt is tightly in place. I thought someone said the length of engaged threads into the hole should be equal to or greater than the bolt diameter, to provide enough tensile force (clamping force).

  5. Ed


  6. "I thought someone said the length of engaged threads into the hole should be equal to or greater than the bolt diameter, to provide enough tensile force (clamping force)."

  7. Correct. This is the rule of thumb I've used for many years. Dr. Mosley may have additional input, but I think the logic is sound.

  8. Josh Walton - ‘68 Conv., ‘67 coupe


  9. When dealing with studs I like to see at least one diameter sticking out past the nut also. Found this on Fastenal’s site:

  10. “For carbon steel fasteners (including tapped holes) the length of engagement would be limited to approximately one nominal diameter (approximately 1-1/2 times the diameter for aluminum). After that, there is no appreciable increase in strength. Once the applied load has exceeded the first thread's capacity, it will fail and subsequently cause the remaining threads to fail in succession.” Page has some good reading, this bit about thread strength is the bottom of the page. There is also a section explaining why rolled threads are preferable.

  11. https://www.fastenal.com/en/78/screw-thread-design


  12. Another note, if you want to chase threads on a bolt, stud, or threads cut into an object it is always better to use a thread chasing tool and not a cutting tap or die. Especially if the bolt or stud has rolled threads. Cutting material can make the threads weaker.

  13. Michael Mosley



Sealing Parts

  1. Pans and covers come with two types of seal surface. If its completely flat (typically on axle housings), RTV sealer is required. A conventional gasket will not seal. It also has to be RTV that is compatible with the fluid e.g. synthetic gear oil requires grey RTV (there is a Chrysler TSB about this; the oil will attack blue, black and red) (for engine use, it must be labeled as being safe for O2 sensors, if the vehicle is so equipped; black and grey are permissible).


  2. If the seal surface has a longitudinal stiffening ribs stamped into it between the holes, it is designed to be used with a gasket. It can be used with RTV though. In either case, the seal surface has to be straightened with a hammer and dolly if necessary. If used with a gasket, it will be deformed around the holes, particularly if it was tightened without using a torque wrench, and must be straightened.


  3. When using RTV, don't use too much. Make a circle around each of the screw holes, then connect the circles with a line. There should only be a tiny bead squeezed out after the screws are tight. Do not fill any fluids until the RTV has completely cured (typically 24 hours, but it depends upon atmospheric humidity; higher humidity = faster cure).



Before you Begin

  1. When the car comes back from media blasting, get the body up on 4 jack stands. Now your just about ready to start getting the suspension back on the car.  POR some spots on the undercarriage that didn't have undercoating sprayed on them. That will be due to masking and the saw horse that the car was resting on in the body shop. Now there shouldn’t be any bare metal anywhere to rust!



During Reassembly

  1. When using assembly lube, be generous, it does't hurt.


  2. During restoration of parts, use POR 15 as a rust inhibitor. You can buy it almost anywhere - search the web.

  3. http://www.por15.com


  4. During reassembly, use tape on the body after painting, It saves the car paint from chipping when putting back parts during reassembly.


Bolt Orientation

  1. The way Chrysler put in bolts without reference: Put in bolts from front of car towards back.

  2. Graveyard Cars


Nuts Replacement

  1. Nowadays they use a nut with nylon inside to prevent nut from backing off. They used to use a crush nut. They put as wedge on the nut. Nut has oval one side, round on the other.



Final Reassembly

  1. check all fluid levels: engine oil, antifreeze, transmission oil, grease suspension, differential fluids (If you can touch grease in rear end filler hole, it is full enough. You don’t want it over that point) ...

  2. Check linkages for any missing cotter pins, check brake lines, all clips are in place, emergency brake is tight, leaf spring hangers, tank.

  3. When test driving, check for rattles and squeaks, .... braking, heating, ...

  4. Graveyard Cars



Order

  1. Begin with replacing and installing brake lines. Install the brake distribution block and right front brake line. It is much easier to get them in while the engine bay is empty.

Before Starting Car

  1. For the First Time Pre-oil the engine prior to starting with a drill.

  2. Instead of pulling the distributor, do the following: - pull the plugs - squirt some oil into each cylinder - crank the engine with the starter until the oil pressure comes up

  3. Make sure the gauges all are working. Check all your fluid levels before you put the key in.

  4. Have a fire extinguisher handy. Not kidding too much work went into it!

  5. Mike Jarvie - ’68 FB


Start Up the Car

  1. It appears the Mopar engineers did not feel it was necessary to fill the lifters with oil prior to starting up an engine after a cam change after re- assembly with liberal amounts of cam lube. They would fire it up and run it at 2000 rpm for twenty minutes to set the cam lobe pattern - the lifters will clatter initially but that will go away as they fill with oil and the lifters won't be damaged.

  2. However, it seems to me it still begs the question of why take the chance on scoring bearings or damaging lifters.

  3. Steve Toth


Start Up Troubleshooting

  1. The proper steps to take if all checks out, start looking at weird stuff like a bad EI module, bad points condenser, cracked rotor or cap, carbon traces or moisture inside cap, etc. I've seen all these cause backfiring/ misfiring.

  2. Ed


  3. Pull no. 1 plug out, put your thumb over the spark plug hole, have someone bump the starter. You will know when you are on compression stroke. You will feel the compression. Look at you damper and readjust to top dead center. Then make sure your rotor is pointing to no. 1 cyl wire on the cap. If not, pull the distributor and rotate 180*. If it's backfiring through the carburetor, then your timing is off. If you wires are positioned correctly, your distributor is off. That's assuming your distributor drive gear is installed properly.

  4. Jim Conner - ‘6


  5. The crank turns two revolutions for each single turn of the cam and distributor.

  6. TDC occurs on both the compression stroke (rotor at no. 1 wire position) and at the exhaust stroke (in order to expel exhaust gas). If you are 180* out, you are firing on the exhaust stroke. You are also firing somewhere else while an intake valve is open, causing backfire out of the carburetor. You can take the left valve cover off and watch your rockers to see when both valves are closed at TDC, but the thumb in the spark plug hole is easier. Just pull your coil wire off while bumping the starter.

  7. Jim Conner - ‘6


Start Up Without the Dash

  1. 1. Run a hot lead from battery to remote starter on the starter then to ballast resistor

  2. 2.Wire to coil to distributer.
