Good evening, this is the first time that I've posted a question on the new website. It's about a second washer on the left-hand side of the front diff mounting plate, described in the official British Leyland Parts Catalogue and Rimmers catalogue, as a distance washer, part number 134603. Bear with me!
I run a 1980 spitfire 1500, one of the last made. When I bought the car it had been fitted with a replacement diff and rear spring. Very often after a long run, when reversing, the car would judder, shaking the exhaust. I replaced the rubber mounting bushes last year with Polybush ones; it was obvious they hadn't been changed when the diff was done. While it has more or less cured the judder, it still isn't as smooth as I would like and it was only by chance that I was looking through a couple of parts catalogues when I noticed this distance washer, which was missing from my car. I ordered one on Friday from Rimmers and it arrived yesterday morning. In the catalogues it is shown as being fitted below the normal washer, i.e. the ones that are fitted to both sides; but the hole in the washer itself is the same size as the Polybush (the captive stud is stepped in diameter to suit) which suggests that it is fitted under the Polybush and then the normal washer under that, then the nut. If it was fitted as shown in the catalogues, given the different diameters, it would not be effective at all.That is how I have fitted it although it must be compressing the Polybush mountings on that side to some degree. The car is fitted throughout with Blue "Comfort" grade polybushes. (Superb.)
I take that it is there to stop the diff twisting under torque in reverse?
Sorry for being so long-winded!
So the big question is have I got it right? I have a variety of workshop manuals but none of the mention it!!!As always, your experience, thoughts and comments would be appreciated!
