Hi All,

I am thinking of buying a secondhand head for my AQ145a.

Can anybody please tell me if there is a part number stamped on it and what it would be to distinguish it from an auto head. Also how can Identify that it is a marine camshaft?

Many Thanks

Nick

Nicholas, the AQ145A is a B23 block that was manufactured only for a short period of time (sometime between 1982 and 1984) and the head (to the best of my knowledge) is not interchangeable with other models. There should not be a difference between "auto" and "marine" heads. The part number for the head is 1276371 (old) and 857532 (new).

The cam on the AQ145A is a K cam. The letter should be stamped at the end of the camshaft (flywheel side if I recall correctly).

Hope this helps.

El, once again you have come through with the information. I don't know what this forum would do without you and the other senior members giving your time so generously. Very much appreciated and thank you one once.

Regards

Nick

You are welcome, Nicholas. Glad to be of help.

By the way, the K camshaft should be Volvo part 1336775 (new number), or 1306167 (old number). Both parts correspond to the same item.
