  • Themen-Opel für das US-Treffen in Carlisle, PA in 2020

    I received a new batch of V-belts (Anm.: Keilriemen) yesterday, the calculated length for driving the A/C compressor and the power steering pump was off by one size each on my first try.
    So today, I finished my bracket for installing the power steering pump and tensioning its belt. The bracket is not pretty, it is the result of cutting, welding, re-cutting and re-welding the bits and pieces together. Maybe I could send it to RallyBob (Anm.: Ein sehr talentierter Metallbearbeiter im US-Forum), and had him make me a good looking substitute :P But hey, it's doing its job. Before putting it in finally, I will sandblast it to at least have a uniform appearance on all sides. Rust won't be a problem, it's made of 316 stainless steel.
    Anyway, the main accomplishment here is that I can tighten both belts (engine to A/C, and A/C to pump) independently from each other. The PS pump bracket is sitting on top of the A/C compressor, and moves with it when the belt is tensioned. Yes, the angle of the PS pump can change a little over time when the belts stretch, but right now the pump angle is just slightly tilted to one side off vertical, and with the stretched belts it might just move a few angle degrees to the other side of vertical. I'm not expecting a lot of belt stretch in the first place, since both belts are very short to begin with (32" and 29").


    And now, it's POOL TIME!!!

    The front brakes are done!
    After a lot of discussions on the German Opel RWD forum (Anmerkung: "Opel Hecktriebler Forum"), with lots of very knowledgeable people involved, here's the documentation:

    • My Rekord was one of probably only a few dozen (or few hundred) Rekords with ABS. This was offered in 1986 for the first time from Opel, in the last year of the Rekord before they replaced it with the Omega. This ABS cost about 3,000 German Marks, while the car itself was only priced in the low 20,000's.
    • This ABS version had different (larger) front axle spindles, hubs (with included ABS ring), wheel bearings, and brake rotors. While the rotor diameter and thickness was identical to the regular vented non-ABS version, the hub connection had a larger diameter and 6 bolts to the hub instead of 4. Nobody in the whole wide world has any of the ABS-version brake rotors. They are not even available as unobtainium, they just plainly don't exist anymore.
    • I ended up converting to the front brakes from the Omega B / Cadillac Catera. Not a single dimension of them is identical to the Rekord (besides the hole pattern of the caliper), but I was able to make it work. My old calipers, and the new rotors and pads (non-ABS and not fitting my Rekord) were sold here.
    • The Catera rotors have a hub center dia of 70 mm and needed to be turned up to 94 mm diameter.
    • The Catera rotors have 5 holes (which is the 5/110 mm wheel bolt pattern) of the Catera. This comes from the completely different mounting concept of these rotors. While the Rekord rotors are bolted to the inside of the hubs with the hubs having studs inserted to attach the wheels, the Catera's rotors are going over the outside of the hub, and the wheels are held by wheel bolts going through the wheels and the brake rotors, to screw into the hubs. Plus, there is a 6th hole in the Catera rotors to screw them into the hubs so they don't get loose when taking off the wheels.
    • After opening up the center dia, I drilled the six 11 mm holes (for M10 screws) into the flange of the rotors. It is astonishing that it was possible to do that without any interference to the existing holes. The rotor flange looks like a Swiss cheese now!
    • The rotors are a great deal larger in diameter than the ones from the Rekord (296 mm vs 246 mm), the thickness is 28 mm vs 23 mm. I had to cut off quite a bit from the dust shield, to get them rotating freely without touching anymore.
    • The axial position from the calipers to the rotors was off. When bolting the rotors on, they touched and blocked the inside of the rotors. I fabricated some spacers out of 316 grade stainless steel (German equivalent: 1.4401, aka "V4A") in 1/8" (3.18 mm) thickness.
    • Of course, all bolts were tightened down with the specified Loctite and torque.

    I might have forgotten something, but the neighbors just arrived, it's time for pool, beer and music now!

    Solange die Wanne dicht ist? Es sei denn, ein TÜV Prüfer würde "annehmen" dass die Reparatur nicht fachgerecht ausgeführt wurde und das Zeug abfallen könnte. Zur Not mache es sauber und spritze etwas Alufarbe drüber, dann sieht man's nicht mehr.

    Kein Einfuhrzoll für die Nähmaschine. Bis 800 $ ist zollfrei, die nächsten 1000 $ kosten 3%, danach muss es angemeldet werden und der Satz hängt davon ab was es ist. Für ein komplettes Auto zahle ich 2.5% Zoll, muss aber dann bei der Zulassung noch die üblichen fälligen Auto-Verkaufssteuern in Höhe von 7% zahlen, die hier auch für Gebrauchtwagen anfallen wenn das Auto aus einem anderen Bundesstaat oder dem Ausland kommt.

  • Brauche Hilfe für Opel Nähmaschine in Berlin

    Wo es bei mir "die muss ich haben" gemacht hat war, als ich den Schlüssel für die Schublade, die Garnspulen für den Unterfaden, und die (sogar gut erhaltene) Bedienungsanleitung sah. Alles das war noch nie bei einer Maschine dabei die ich in den letzten 10 Jahren angeschaut habe.


    Die Zusatzkosten für den Verkäufer die ich für die Verpackung zahle halten sich in Grenzen. Der Versand wird wohl in der Größenordnung von 1,000 Euro liegen. Habe schon drüber nachgedacht ob in die Kiste noch ein guter C20LET reinpasst :D :thumbup: :pinch:

    Ich habe diese Nähmaschine auf ebay in Berlin gefunden, leider bietet der Verkäufer keinerlei Arten des Versandes an.
    Ich weiß es ist ziemlich weit hergeholt, aber gibt es ein Mitglied hier der die Nähmaschine für mich abholen und verpacken könnte? Ich kümmere mich dann um die Abholung der Frachtkiste beim Mitglied.
    Vergütung für die Hilfe und Bezahlung aller Kosten ist selbstverständlich.


    Ansonsten, wenn jemand selbst an der Nähmaschine interessiert ist, dann viel Glück damit!
