Installing a new R-4 compresssor in an '83 240D. It came with 5 seals and two aluminum inserts. The insert installation seems obvious: the short insert goes in the high pressure side which has little space in the compressor, and the long insert goes in the low pressure side which has much more space. Tap the inserts in the hose block with a plastic hammer, etc.

The only instructions as to which seals to use are that after tightening the hose block to the compressor there must be a 1.2 mm gap between the hose black and the compressor. Only two seals seem to stick up high enough and evenly enough that the 1.2 mm gap would result after tightening. That is with the green edged metal/rubber seal in the high pressure side and a brass edged metal/rubber seal in the low pressure side. I don't see any way the other seals could be used. This is the first compressor I've installed in a Mercedes. Am I missing something?
Thanks,
Gerry
