Yanmar 1GM water pump seals

[wee_niall]

Need some help guys as my memory has failed me....i stripped my 1GM pump a few weeks back to replace the leaky seals and i was going to pop it back together now i have the replacements but i've forgotten how the seals go! Can anybody tell me? I found a schematic drawing but it doesn't really show me which way round they go.....

The open sides of the seals face away from each other.

On the 3YM30 there is only one water seal. It is easy enough to remember ..... the open end of the seal is always inmost as it is the water pressure in the channel that keeps the lips of the seal in contact and doing their job. This is good for any seal.
