Alpine White Zender Kit E24 633CSI

[Jdesign]

I started to match the hardware to the BBS logos, and the lips are much closer to being polished now. I also got the new hazard switch in the mail already. I installed it and now have turn signals on one side of the car. I think a little more tracing should bring the issue to the surface.

@m42b32 was nice enough to share a link to a guy on maxbimmer who has access to build sheets. Although my car is right at the beginning of them recording the data, he was able to supply me with this, which I thought was cool;

"At least 68 - 1983-1984 BMW 633CSi Manual (5274) - NA **Incomplete** painted in Alpine White (146) with Cherry Leather (0162) interior were built for the US market.
None were built for the Canadian market.
The most rare option in this car is the option S209A - Differential lock 25%. It was installed on 619 out of 2,821 cars that are available to me.
Keep in mind that out of 3,592 built, there are no build sheets for 711 cars."

Turn signals fixed!!

Turns out the inside of the new switch was moldy causing some issues, then to add to that, one of the small T4 bulbs in the corner lights had a loose wire causing an arc. So that was giving me an intermittent flash. It was hidden really good behind the light. I figured that out by removing that whole corner section to check the harness behind the headlights.

Now my next big mission is springs and struts.

[Jdesign]

Accomplished a little bit more this weekend. I got new wipers (impressive I know) and I got the side skirts remounted with nutserts instead of the lag screws that were previously used.

Here's what's left of my list:

Parts to order / find

• Speakers (4 minimum)
• Wipers
• Door light switch(s)?
• Tires for Style 5's
• Springs /Shocks/struts

Labor

• Turn signal Relay needs to be cleaned or replaced
• Figure out the Parasitic power drain
• Finish buffing the entire car
• Remove the pin stripe
• Installed the side skirts with stainless hardware
• Refinish the Style 5's

I sadly have no pictures to add.

Update!

Wheels have been a slow process as I have been busy with other projects. But I have some images to share. I am really close now. I just need to finish polishing the lips and assemble them!

I had to make spacers for the logos in order to get them flush to the hex's. I cut slices of PVC and used ______ to bond them all together so they wont fall off.

Before

Spacers

After

I also coated all the wheel hardware with a high temp transparent clear that I tinted gold/yellow/orange. I was really trying to match the centercaps with the materials at hand. 3 batches later I gave up and settled on this. Its slightly darker than I wanted but it still looks nice. Next time I will just buy gold plated hardware.

I finally have new springs, front struts, and rear shocks. 

I started installing them a few days ago but have been hitting some speed bumps along the way due to a combination of missing and seized parts. 

FRONT

I was able to break all the bolts loose with minimal effort. Before I removed the main assembly I broke the strut cartridges loose while they were still on the car. I figured this was better than fighting them on the ground. One side had a blue Bilstein bellow which was covering the strut shaft but was severely dry and torn. The other side was completely exposed although I found reminisce of  a bellow once I had it all apart. 

See the difference between having a bellow and not. Its unclear the history here, but I think the passenger hub/knuckle (Image on left) was replaced at one point, or the driver side (Images at the right) was exposed to elements more often than the passenger side(i.e. parking two wheels on the grass often or for a long period of time) as not only was the collar solid rust in color, but the whole hub assembly was much rustier that the other. 

Spring comparison:

Upon pulling the cartridges out, which were almost airtight in the strut tubes, I found out that the old struts were really nice(at one time) Bilstein B8's. Check out the old labels.

 

The replacements I purchased were the touring models, which are vastly different from the B8's. I was about to learn the differences. First off, the strut shaft diameter is much larger on the B8's as seen below. On top of that the overall strut housing of the tourings was smaller about 1-2mm, they had stamped end plates vs. the threaded B8 counterparts, and the housing was about 5cm taller.

This wasn't an issue until I went to insert it into the strut tube and the collars that came with the tourings only threaded in halfway before cinching tight on the cartridge. This will hold, but Im not thrilled about the amount of threads exposed to the elements. 

I posted on an E24 page on Facebook and received confirmation that this is how they fit and I should not be concerned. I will be purchasing bellows to cover the threads so Im not really worried about the threads as there is plenty threads in the tube holding the cartridge in.

I forgot that I needed bellows and bumpstops as they all crumbled when removed. So those are on order and will halt reassembly up front until they arrive. In the meantime I cleaned and painted the strut tubes/hubs and recoated the wheel wells in rubberized undercoating.

Up next; My struggles with the rear Shocks.

[Jdesign]

REAR

How hard could this be? Its only 3 nuts and 1 bolt per side!

WELL......I thought t he hardest part about the rear is that the top of the shock is mounted in a very confined space. Right behind the rear seats the is a small access hole that took a combination of swivels and extensions to get to the front nut. This is 1 of 3 top nuts that holds the shock assembly in place. the other two are accesses from the trunk, and you have to remove all of the carpet paneling and contort yourself to reach them with a standard box wrench as there is not enough height to fit any other tools in there.

Heres the access hole:

a closer look

what I used to get the nut which isn't even visible in my pictures:

 

Here is a view of the shock top from inside the trunk:

On to the lower bolt......

So, I learned something interesting that BMW must have also learned after the E24, E28, and E34. It is unnecessary to have the rear shocks sleeve or dowel pin into the rear swing arms. Doing so will cause issues if the suspension is old, worn, or corroded/rusty. Something this car is. 

The first side came out without a fight. The second side though, the second side fought me for a few hours,......................... then days. HEAT, BANGING, PRYING, PENETRATING OIL, SCREAMING, AND CRYING, all proved useless. What eventually broke the dowel free;  TIME. I let the dowel soak for two days. Every time I walked past I sprayed it with penetrate again. Finally on the third day, I got a very large 4x4 block of wood, pressed it against the shock, and wailed on it with the largest BFH I had. 15mins later I was the winner at the worlds most annoying High Striker.

Here I am trying a useless method. I got that pickle fork all the way in there and the shock mount rubber was the only thing that was deflecting.

  

Heres what the easy side looked like. 

And final success with a comparison image. I have since got the car on the ground but haven't had a chance to drive it due to the weather.

I’ve give up trying that on parts cars, same experience where one comes off no problem.

I enjoy a good challenge.

[Jdesign]

Also, I forgot to add I am 98% done refinishing the Style 5 BBS wheels for this car. 

Before on the right, After on the left

[Jdesign]

I got one wheel bolted together but not loctite and torqued yet. My hunt for tires has begun. Anyone that has a lead on a set of 235/45r17’s let me know!

[Jdesign]

Just a little compare and contrast

What did you use on the insides of the barrel? Looks great!

[Jdesign]

Just a satin black high temp aerosol.

[Jdesign]

I got tires for the wheels this weekend. Bridgestone potenza 245/45R17's. I hope to install them this week when I get the tire machines hooked up.

 

This is the same size tire:

More progress.

I needed to get this off of the lift about a month ago but I was still waiting on parts. So I tossed it together and put it back on the ground. Over the holiday I found some time to revisit it again and install the parts that finally showed up.

New parts that Arrived:

• Brake Rotors
• Lemforder Rear sway bar links
• Lemforder Rear trailing arm links
• Sachs Front shock bellows and bump stops
• Sachs Rear shock bellows and bump stops

New Vs. Old

With the new rotors I will be installing new pads. So I decided to repaint the calipers too. Originally I had a seized front caliper that I tore apart and replaced the seals when I first got the car running. Taking it off and prepping it for paint I noticed that the piston's gasket/boot (not the seal) was not all the way on in one spot. I fought with it for over two hours, taking the piston in and out reinstalling the seal. Im to the point now of just buying a new caliper. If you look at the bottom (or top) where the perimeter of the seal is close to the casting you can see its deformed. No matter what I try it always deforms right there. I cleaned all the mating / sealing surfaces many times. Grrrr.

[Jdesign]

Well, I hope this is the right caliper. I looked at all the images and there are a few casting lines that vary, but all the mounting locations are the same....

Crazy thing is that I was struggling to  find a reman caliper for under $100. I stumble onto this one and its $53.91 and there are like 40 of them on eBay. I buy it, and went to look that the listing today, the price jumped up to $122. LOL  Maybe it was a mistake and they thought it was a rear?

Also realized I was sent the wrong rear brake pads. So I am ordering a different set today. I was reimbursed for the wrong ones and was told to keep them. I don't even know what they are for.

**EDIT** I googled it and they are pads for an E12 based car: BMW E3 E9 E12 E24 528i 530i 2800 Rear Disc Brake Pad 

More pics to come as I get everything back together!

[YoungCR]

Ughh why are those calipers so expensive! You could buy a brand new 540i powerstop calipers/brackets and decent rotors/pads from Rock Auto for $130-$140. Same setup I bought for my e34 bolts right up, no cores on the calipers.
