Ford Dover & Dorset Engines

[BoatingBeginner]

I gave this bloke a copy of the full Ford Dorset range service manual, which he has kindly posted on his amusing blog:

Does anyone know whether the Dover and Dorset engines are interchangeable? I know there are differences internally, but are the bellhousings and sumps a straight swap?

The Dover will directly replace the Dorset, externally the major difference being the injection pump drive arrangement. Dorset's are external drives and you can run the raw water pump from the same drive, on the Dover you need an arrangement to replace the air brake compressor and steering pump (available from Lancing). The industrial sump fits the Dover, but you have to alter the oil pick up pipe and bracket.

Dorset and Dover engines were made at Dagenham engine plant Essex.

But dont ask me, i have not a clue.

What do you want to change?? the complete engine or bits from one to the other? I know the exhaust maniflods are different and the timing gear is bevelled on the Dorset and straight cut on the Dover. Apart from that unable to assist

Have you seen the size of his lunch box ! , dover production stopped @ dagenham around 18-20yrs ago , some machinery was shipped to a plant in turkey where they carried on with limited numbers , the "marine" crank made @ D,E,P had a diff process from a road crank , also a different alloy sump pan .

No but I know it would have to carry 500kg, but then again him being an Essex Boy???

Some of the old boys here at Dagenham, say the crankshaft was very heavy and large.
If still in production i would put it down my trouser leg..

Assuming you are talking standard engines i.e. 120/150 hp Complete engine swop is O.K. but dozens of internal & external parts updated, including manifolds, but as I say footprint is VERY similar.
