Requested: Honda Assembly Plant Manufacturing Markings
Hello all, I found no result for this search on this sites forums but I am looking to see if you all have encountered any unique manufacturer markings done during assembly of your Honda vehicle.
I am glassy eyed in my approach to Honda vehicles from the 90's as I do believe they will one day be very coveted cars since everyone in my generation had one in highschool, which is why there are so few clean chassis left.
My civic hx has grease pen markings on the under side of the hood and on the gas tank under the car. The hood on my vehicle is the factory unit as it still retains all stickers, the car still has the factory Honda headlights and Honda front bumper (and they all have matching paint and matching hail damage.)
In 1997 and newer cars they went away from the grease pen markings, but still used colored grease pens on suspension parts
On 1997 and newer cars they adopted vin number labels to identify cars to their parts as the went down the assembly line. To find the location of factory labels to determine if your car is original see here
https://honda-tech.com/forums/honda-...start-3288303/
Please post up if you have seen any grease pen markings or stampings you have found in your vehicles that could have seen done on the assembly line. Maybe one day we can look back and see restorations done down to these grease pen markings
As best I can tell on car made in or before 1996 had these markings from the liberty plant in Ohio. In 1997 Honda developed a six sigma computer program to implement global quality control from standard assembly blue prints, and before 1997 cars were made using an approved stamping sent by Honda to the manufacturers plant
Under side of the hood
On my shock tower
Drivers side fender
On my drivers side rear lower control arm
No idea what the A stands for, it is one the gas tank and rear shocks and B is on the front shocks*
I would also like to see some window stickers and the dimensions. Here is one I found online

Re: Requested: Honda Assembly Plant Manufacturing Markings
Thank you sir.
I spent a few hours image searching for anything related to manufacturer markings, assembly markings, inspector markings and had no results.
Maybe my car just rolled off the line at an odd time and was the last car in the 96 line up, or last car on a friday. Hoping others can shed light on it

Re: Requested: Honda Assembly Plant Manufacturing Markings
I have emailed the assembly plant in Ohio to verify however I believe my car was one of the last 96 models to be assembled on the line.
The build date on my hx is may of 1996

Re: Requested: Honda Assembly Plant Manufacturing Markings
Factory was of little help, but said markings were used only to distinguish part line up changes or for secondary inspection approval. My control arm has a serial number on it and the marking was most likely to keep serial numbers correct by year
So I am under the assumption with a may of 96 build date my car was one of the last to roll off the line as a us spec 96 model
There are no sales figures for the 96 honda civic, if some one could find the sales figures for 96 it would identify if my serial number (the number at the end of the vin ) was one of the last produced
Also I assume this is common but my chassis has the build date stamped on both shock towers

Re: Requested: Honda Assembly Plant Manufacturing Markings
I had to call and they really didn't seem to understand why I wanted information on the assembly of a 96 civic (especially since the plant doesn't make civics anymore) but they took my info and said they would contact me back. I had a line supervisor call me and explain their quality control. Most markings are removed after the last qc inspection, if any were found. He was suprised to hear I had several parts with markings but couldn't offer any insight as to why they remained on my car.
If I understand the vin sequence correctly my car was number 54,380 built that year which would sound about right if I could find a 1996 us sales figure for the honda civic
I know to most "tuners" this thread is pointless, but it is getting harder and harder to find clean 92-99 civics as their value is less than the sum of their parts, making most of them end up in a junk yard
I can forsee a day where we are in our 60's and see clean unmolested cars bringing good money.

Re: Requested: Honda Assembly Plant Manufacturing Markings
Ever check your VIN to make sure it was made in Ohio and not Canada? I had a 96 and found out it was made in Canada, They didn't start making them in Ohio until the completion of their East Liberty Plant I believe. Numbers/ chicken scratch shouldn't be visible accept on electronics.

Re: Requested: Honda Assembly Plant Manufacturing Markings
The control arm is likely a replacement, like the spring beside it. Honda wouldn't need to mark what year the part is with a big white marker. The run one model a year, and even so parts are organized and marked in the container they are in not on the part. The only parts that you would typically find with any markings is usually electronics that Honda doesn't make in house. But with the 96 being the first model year of the 6th generation for Civics. The yellow markings are possibly a certain type of double check on certain parts for whatever reason. That could explain the yellow marks on the parts. Someone might have had to check parts after the car was put together. They checked /marked and then under the hood would be the persons badge/clock #, date of check and # for some reason numbered parts. Hope I helped.

Re: Requested: Honda Assembly Plant Manufacturing Markings
Vin states L for liberty plant.
I'll check the serial number on the drivers side rear control arm and post a picture of it. How do you know the spring has been replaced?
I appreciate any info, the hood markings are what made me curious. Figured I would see if anyone else has found anything similar

Re: Requested: Honda Assembly Plant Manufacturing Markings
I have inspected a few other civics and did not find stamping numbers on the shock towers.
Mine can't be the only one to have a chassis stamp, anyone have those stampings as well?

Re: Requested: Honda Assembly Plant Manufacturing Markings
I found one on my rocker arm assembly when I was doing my valve seals and valve adjustment.
I should have taken a picture but I didn't even think of it. Next time I have my valve cover off, I will wipe off the spot with the permanent marker writing and take a pic and post it here.

Re: Requested: Honda Assembly Plant Manufacturing Markings
All civics in 96 should have tower stamps, my chucked scratch under the hood is likely from a failed quality test at the end of the assembly line
.
The number 76/76 most likely symbolizes the qc checks the vehicle passed through on the assembly line to approve its construction. The extra markings just to purely ensure the first model in the process line is receiving the correct parts as it moves through the line. A on the gas tank to pass under side inspection, marking on the arm to symbolize rear drum and suspension, marking on the hood to show passing engine check. I would bet if it pulled the carpet or dash I cold find inspector markings there as well for electrical and interior qc inspection
The symbols on my fender cross back to a company in Taiwan. Most likely a very early recreation of a factory part with no indication of being oem, or perhaps just outsourced as oem replacement licensed through Honda, or more likely a cheap aftermarket fender to replace an old dented factory fender
Quoted from edmunds.com
From Hondas own world history civic production page suggesting production "kits" I assume meaning assembly guides and specifications for models. After 97 the production was done electronically ensuring seamless conformity
Through 1996, worldwide production figures are the total of Japanese production (CBU+CKD) plus exports of knockdown kits.
From 1997 onward, these figures are calculated on an off-production-line basis, excluding domestic production (CBU+CKD) and overseas production (CKD).

1996-2000
A revamped Civic lineup debuted for 1996. The new body featured larger light clusters fore and aft, a grille (chrome-accented on sedans) and a crisp character line that ran the length of the car. Hatchbacks now had the 103.2-inch wheelbase of the coupes and sedans, and overall length was up around 2 to 4 inches, depending on body style.
Sedans were again offered in DX, LX and EX trim levels. A new coupe, the HX, joined the DX and EX coupes. The HX coupe essentially replaced the VX hatchback, offering high mileage figures from a fairly powerful engine. The revised VTEC-E engine (now at 1.6 liters) in the HX put out 23 more horsepower (for a total of 115 ponies) than the previous version but now "only" scored mileage figures of 39 in the city and 45 on the highway. A gearless continuously variable automatic transmission (CVT) that promised seamless performance and manual-transmission fuel economy was introduced later in the year as an option for the HX. The hatchback lineup was trimmed down to two models, the CX and DX. A new 1.6-liter 106-horsepower engine that earned Low Emission Vehicle (LEV) certification powered the CX, DX and LX, and a slightly more powerful 127-horsepower VTEC-assisted version was found in the EX models.
Excluded from the redesign, the del Sol was now in its fourth year and got a host of tweaks to keep it current. The base model (S) got the new 1.6-liter 106-horse engine fitted to the new Civic, Si models got the beefier suspension of the VTEC, and all versions got a freshened front fascia.
In 1997, all Civics came with 14-inch wheels, DX models got full wheel covers, the LX sedan received air conditioning and, strangely, EX coupes with manual transmissions no longer had the option of antilock brakes. As this would be the last year for the del Sol, Honda made no changes.
Not much happened in 1998, save for new wheel covers, an exterior handle for hatchbacks and the addition of map lights.

Re: Requested: Honda Assembly Plant Manufacturing Markings
I had the opportunity to view a 96 dx with a zc swap and the date code on his shock towers were upside down except for the day. So the 4 was upside down and the 28 was right side up and the 96 was upside down
Can anyone with shock tower stampings please post pics of them

I believe this is factory markings on the crank main cap girdle on a D15B7 pulled from a 95 CDM CX Hatchback EH2.

Re: Requested: Honda Assembly Plant Manufacturing Markings
Nice, those look legit to me. The crank is probably an indication of the balancing it took during production. Must have been a pretty low mile motor to be so Clean
Also not sure if this is unique or not but it is a production/assembly markings

Not really low miles but probably decent oil change servicing most of it's life.
