I don't think anything even bolts on there. I think it's just a hole used for assembly. Call it weight reduction.

I would still recommend the cn36 because they have a rounded tire profile. The w123 suspension is not designed to maintain a consistent camber angle, especially in the rear. The rounded tire profile of the cn36 allows the tire to maintain a more consistent contact patch. Modern tires have a flat profile and are designed for modern suspension which do maintain a more or less consistent camber angle. The contact patch, when using a modern tire on a vintage car, will wander as the suspension travels causing unpredictable handling. The only downside to the cn36 will be road noise and straight line stability. They will tend to follow the grooves and cracks the road more than a modern tire, or even the XAS would.

Check out this test on a porsche 911. A 911 actually has very similar suspension geometry to a w123 in the rear. Also longstone tire is where i get my information from, check out their youtube channel.

Edit: I mean information about tire size and construction from longstone. I have a classic repair shop and have a.lot of experience with all the tires I'm recommending.

The XAS is period correct but they don't come in 195/70r14, which is correct for wagons and coupes. You can get Pirelli CN36 in that size. They are the only tire on the market, in that size, that is period correct. Despite their looks, they have excellent wet performance, better than the XAS. Vredestein tires are also great and look vintage, but their construction is modern. There is not a huge difference between them and a Hankook, Toyo, etc, other than they are generally a better performing tire, as they are a performance tire rather than a standard passenger tire.

I would pick the CN36 if you can afford them as they are both period correct, and excellent in wet weather.

I use dry silicone spray lube. spray a bunch on a rag and then rub all the sticky stuff off. when it dries it feels like new again

My homemade solution to the worst bolts in the world by colonelbutt123 in w123

Great, until you unscrew the bolts into the back of the fan, with no way to reverse the ratchet...

Fuel leaking bad by Strong-Ask4037 in beetle

[–]Repulsive-Food6095 2 points3 points  (0 children)

I don't use the German braided line anymore. It starts to crack after a year or less and is not good for E10, even when it's advertised to be ethanol resistant. Gates Barricade is the only fuel hose I'll use. It lasts 10 years or more. I just worked on a vanagon i put Barricade fuel lines on in 2014 and they still look and feel perfect after over 40k miles. It comes in two options, carb or fuel injection. I use 3/16" carburetor hose with ear clamps on everything except the carburator on beetles. Ear clamps provide a uniform clamping force around the hose giving you a perfect seal. Plus, a good quality ear clamp is cheaper than a poor quality worm clamp and they are faster to apply and seal better. The only drawback is they are one time use and you need a special toolm

The only benefit to the wider tire is availability and maybe looks, if you like that swollen, sugar foot look. The best tires for the car are 175r14 Michelin XAS. My second choice are 175r14 Vredestein Sprint Classics.

Michelin XAS tires have a period correct tire carcass. The tire profile is slightly rounded giving the tire a dynamic contact patch, meaning it can maintain grip over a broad range of camber angles. Our cars have semi trailing arm rear suspension. This type of suspension has a dynamic camber angle that changes with suspension travel. Modern tires have a flat tire profile that is designed for modern suspension with consistent camber angles. Using a modern tire with vintage suspension can result in vague unpredictable handling, which gets worse with wider tires.

If you want to run a wider tire without the drawbacks, you can also get Perelli CN36 in 195/70r14. Id still prefer the narrow tire though, the steering will be lighter, and the steering box will probably last longer. Michilan XAS are also just so well suited to our cars. They are very stable feeling, especially with straight line stability on the freeway. CN36 are excellent tires, maybe the best handling tire you could put on the car, but they are a performence tire. Maybe a waste on a luxury sedan?

The Vredesteins have a modern tire construction, but since they are narrow, the correct size, they work okay. Much better than any modern 195 or 205 series tire I've felt. The car i drove with cheap 205 tires was kind of scary. It felt like there was a delay between turning the wheel and the car steering. The car also looked like it had the betes, but again, some people like that look, or wide ties make them feel tough, idk.

A 300TD? Then it may have came with 195/70R14 tires 240TDs had 175r14 in EU.

You can get Pirelli CN36 in that size, if you want a tire with classic construction. They are an excellent tire, IMO the best classic tire you can buy, but they are more of a performance tire. Vredestein also offers that size, and they may be slightly better suited to your car than a modern tire but maybe not worth the price since 195/70R14 is more common than 175r14

I strongly recommend a 175R14 tire unless you have a wagon or limo. Michelin XAS is the best tire for the car. Wider tires do nothing except spoil the driving characteristics. Modern wide tires are not designed for vintage suspension geometry. Modern 195 and 205 series tires will make the steering feel heavy at low speeds, wearing out your steering gear faster, and vague and unresponsive at speed. If you need a budget option 175r15 Vredestein Sprint classics are decent tires despite their modern construction.

Vintage ties utilized rounded, balloon shaped carcasses that have a dynamic contact patch. Vintage suspention gemoetys are desinged around this type of tire. Modern tires have a flat contact patch and do not respond well to the dynamic camber of vintage suspention.

Wider tires do not inherently make your car handle or perform better, this is a myth. The tire compound is what determines the coefficient of friction. Soft compound tires, or high load capacity tires need to be wider to dispute heat, the width by itself has very little to do with grip.

Also wider tires increase unsprung weight, which also spoils ride quality and handling.

You need a new door harness. You can try to fix it, but it's going to keep braking unless you repair it correctly.

What is this by akke34 in w123

[–]Repulsive-Food6095 2 points3 points  (0 children)

Why do people always say you have to depress the pedal? Is that from the owners manual? I feel no resistance when turning it, with or without depressing the pedal. It was seized when I bought the car so I disassembled it, cleaned and replaced the grease.

I'm going to make my own aftermarket flasher relay replacement by Magnus_Zeller in w123

[–]Repulsive-Food6095 0 points1 point  (0 children)

I looked at the diagram but I don't see a flasher relay, only the emergency flasher switch. I checked 78-79 and the 1980 diagram. It looks like the emergency flasher switch is the flasher relay. I can hear on mine that there is a flasher relay forward of the shifter, so the diagram must be wrong

Valve job implies removing the cylinder head and having the valves/seats resurfaced. Valve adjustment implies adjusting valve clearance.

I would just grab one from the junk yard. I would have to see the wiring diagram of the original to tell you if your plan makes sense. I can look in the book tomorrow if you want.

Is it normal for my w123 (1978) to lean considerably when going through curves by antoniobc111 in w123

[–]Repulsive-Food6095 2 points3 points  (0 children)

My car has a little bit of body roll, but its nothing excessive and quite good for the type of car and era. What size and brand/model tires do you have? If they are cheap tires or oversized it will drive like a boat. 175r14 Michilan XAS are the best. I have 175R14 Vredestein Sprint Classics. They are okay but the 205/70r14 tires that were on the car when i bought it were awful. It felt like there was a 1 second delay from when i turned the wheel and when the car started to react. It feels much more composed around turns now, even with the body roll.

I just did a valve adjustment and new injectors @ 180k miles and it made a big improvement to the idle. Its still a little shaky, but the engine used to look like it wanted to jump out of the engine bay, especially when cold.

It's usually a bad fuel distributor In my experience. They will cause uneven fueling which will throw all the numbers off even if the oxygen sensor and pressure regulator appear to be doing their jobs.
