P/S crush washers 700 1990

I'm into replacing my steering rack ('90 760GLT). The replacement is a reman Cam/TRW design. I've separated the pressure and return hoses at the banjo bolts and am trying to source and replace the copper crush washers. Using a Vernier caliper, I'm looking at four different washer sizes.

I first attempted to anneal the old washers with a propane torch I have on hand and gave up. This AM I called the most local Volvo dealership for replacements. I was told that there are only two sizes. I called TASCA and they also confirmed that there are only two sizes. Maybe I'm too fussy. One size is OEM p/n 18671 they say. An internet search gives: OD 21mm, ID 14.4. The other size is OEM p/n 11996. An internet search gives: OD 22mm, ID 16mm. My caliper indicates OD of 20mm for the former and 20.5 for latter for the washers removed from the return hose. And, yes I know that OD is not the critical dimension, but I'm not convinced that there are only two washer sizes for the two hoses.

TASCA noted that one p/n (two washers) was for the return hose and the other (two washers) was for the pressure hose. I wish I could show them in person that this doesn't cut it. Using the return hose's banjo bolt as an example, I can easily pass the largest ID over its threads and 16mm shoulder to lay flat under the bolt head. The second largest washer will, with twisting, move along the bolt's threads and but not pass along the 16mm shaft. As for the smaller diameter pressure hose's banjo bolt, the same holds for its original washers, that is, the smaller two of the four washers. It's shoulder has a diameter of 14mm.

Any ideas or experiences relating to steering gear crush washers you can share?

For the fun of Volvos,
Mike

    P/S crush washers 700 1990

    I think I've reached personal clarity on my crush washer observations.

    I ordered from TASCA two crush washers of each of the two sizes they have catalogued (p/n 11996 and 18671). I just received them and saw top quality copper crush washers compared to the four that I removed. I don't think heating those that I had removed would restore them to a near-new appearance and performance. The OEM washers are so cheap, it's not worth my time to hunt local stores or resurrect used ones from the dead.

    I'm now believing that my Volvo has suffered from sub-par quality washers and the subsequent leak. The car has a maintenance history that would suggest that when someone in the past installed a reman they used non-OEM washers. I still maintain that each of the these four washers are different in ID.

    This experience reaffirms my belief to use OEM parts where ever possible or beware of the risks of straying into aftermarket.

    Thank you all for your responses. Shortly, I'll share another power steering maintenance snag.

    For the fun of Volvos,
    Mike

      There's nothing wrong with new OEM crush washers, but they're designed to be used only once. Annealing them is just a last ditch method to get the job done without delay if you don't have new ones.

    How did you try to anneal the washers and what were the results? You anneal copper by heating it red with a torch, then quenching in cold water. Always worked for me.

      I was using a propane torch. Had to do it outside since I don't have a suitable enclosed shop. Though I chose a day that was nearly windless, I can't rule out some wind affecting my results. At any rate, I was not able to bring the copper crush washer up to temperature. I then gave up and began sourcing from the nearest dealership. HF is my next shopping source. Thanks for your input.

    captcha-free posting returns? 700 1990

    I know I wasn't that fussy, but it didn't leak.



    Sure sorry to hear about the unsatisfactory results you're getting at the Volvo dealership. I have to think the steering, sourced by several mfrs in your 700 cars, was more in the hands of the rack builders, than Volvo part inventory specialists. If I couldn't find one locally, I think I'd give Jorgen a jingle and see if they might pop a set in padded envelope. But so far, the sandpaper technique has served me well. I don't even go for the torch.

    My dog is worried about the economy because Alpo is up to $3.00 a can.
    That's almost $21.00 in dog money.
