There is a lot to do about our 850er Limo from 1993. Some things have to be done for the TÜV and other things are more or less fun. The parking brake is TÜV-relevant. I think I can do that. The steering is leaky and therefore spongey. Probably not TÜV-relevant, but it has to be done. The car is needed daily. That’s why I wanted to get a used steering, repair it and then mount it over the weekend. And here’s the first problem. I I found only one sticker with the indications 6800275, AC23A414. But not on the steering gear but on the push rod. Can anyone do anything with this? Another thing is a desired motor replacement. Soon the timing belt and the clutch have to be renewed. To do this, the motor j a. We still have a 125 kW engine (to be repaired) in another Volvo. What does everything have to be changed if we want to install this engine in our Limo? Does the entire engine compartment wire harness have to be replaced? What about the control units (engine and ABS)? What about the exhaust system (including catalyst)? What information do you need to answer these questions? I have already called the TÜV. Unfortunately, there is no need for a replacement. “He would call me again,” he said. But that was already a week ago and nothing is happening. I think, however, the TÜV should accept the conversion. There is this 1993 soda with the 125kW engine. The third topic is the exchange of the rear wheel bearings: My soda still has 4-hole rims. I want to get this as much as possible. Unfortunately, there are no more so many suppliers for rear wheel bearings for 4-hole rims. And if, then at high prices. but also found individual ball bearings as wheel bearings. Has anyone ever changed ball bearings? I and I have done this kind of work already, but I would be very grateful for a short instruction. Unfortunately, something has become a lot for a post but I have really limited myself. There is a lot more to do. Thanks already now for your answers.
