Ive had a think and when i looked at my washers in the past after Gilbert pointed out about the dome, 5 of my washers wernt domed. They appeared to be ordinary ones. So i added a dome to them. Is the size of the washer and dome crucial for sound deadening?
Where might one obtain proper domed washers for the job.
According to the parts book the washers are RVL100030

Lol. Gonna cost £8.10 for 6 washers including shipping.
Seems a bit steep. Ill have a look in the scrappy first and see if theres any on the cars in there. If not, i suppose £8.10 would be a small price to pay for potentially silent motoring.
Or just hit the flat ones with a ball peen hammer......
I did that. They are domed now but i dunno how big a dome it should be. My dome may be too big or too small.
They need to touch the metal sleeve in the centre of the mounting but not be touching the rubber part. The compressor also needs to be held up far enough that it doesn't touch the bottom of the plastic box.
