Bukh DV10 diesel engine

[Tullynessle Turnip]

We have recently bought a canal narrowboat in England, UK. It has a Bukh DV10 engine, one cylinder, made in Denmark.
We have the owner's manual, workshop manual and a repair manual - none of these tell how to change the gearbox oil, for instance: looking at the diagrams on the repair manual there seems to be a drain plug underneath the gearbox, and a filler plug on top, and the book says "oil level control through the overflow plug" but doesn't say what or where the overflow plug is! All 3 guides are somewhat lacking in proper descriptions all round!

Are there any people here who know about the Bukh DV10 diesel engine? I would like to find a list of mechanics/service places in England for this engine, also; I wrote to Bukh's head office in Poole (UK) and they just gave me the cold shoulder and said contact T W Marine, a company/boatyard that apparently specialises in Bukh's, They are in Furness Vale, to the east of Manchester (UK). T W Marine don't give an e-mail contact address on their website so yesterday I sent a letter to them by 'snail mail' - let's see if they reply...

Our narrowboat in in Oxfordshire at the moment. The engine is OK at the moment but needs inspecting & servicing as soon as possible - I have already changed the engine oil 2 times (within 4 days, the first oil, you could say, used to flush it) - I put a new oil filter on with the second lot of new oil.
I would like to have the gearbox oil changed, and the coolant (water + antifreeze) changed, and the zinc rod (anti-corrosion device) examined/changed, for starters.
This engine is from 1985, 29 years old, but as the boat is 25 years old the engine may have been used for just 25 years. I should like to look after it and keep it going for a few more years yet.

Always helpful and what they don't know about Bukh isn't worth knowing!

You would be better posting questions on this type of engine on the PBO forum as most are fitted to yachts.

Suggest you telephone Bukh in Poole rather than write - you will find them very helpful over the phone. BTW pretty sure the engine is raw water cooled therefore does not have any antifreeze in it. It draws the cooling water from outside the boat, circulates it through the engine and it is injected into the exhaust run and so back out! The anode is to reduce corrosion when using seawater to cool it. You probably don't need it for fresh water, but ask Bukh.

It will depend on what type of gearbox is attached to your Bukh, BW6, BW7, PRM? A photo would be useful for identification.

I've never serviced my own Bukh but I'm pretty sure that you pump the old oil from the filler hole on the top of the gearbox. As Tranona said, ask on the PBO forum on this site as they know loads about Bukhs there.

That's how it works on my Bukh 20. You stick the plastic tube at the bottom of the little brass pump into the filler hole and wriggle it around a bit until you think you've found the bottom of the gearbox sump (obviously there are various bits of machinery in the way so it won't necessarily go straight down). Pump away (if you're pumping air, you haven't found the bottom yet). Refill with the quantity stated in the manual - but you probably won't need it all because there'll still be some old oil you didn't manage to get out. Don't overfill.

I've had good service (parts) and advice from both Bukh UK at Poole and T Norris over the years.
