Discovered that the air filter on my Yanmar 1GM 10 had 'sucked in' the rag used to winterise the engine and it has wrecked about 20% of the foam around the central metal cone.

A new element is £24.00 (of course a lot less in the USA - currently $19.06) but frankly it only needs a tiny piece of something to wrap around the cone.

So what is that stuff? It looks like foam but would felt do? or a paper element?

What sort of foam, as presumably it needs to withstand diesel around it?

Any thoughts? As I am sure as heck, NOT, repeat NOT parting with £24.00 for what looks like a 2p repair!!!
 
While we are talking about this, what about an air filter for a VP2030.

We have accidentally torn ours, which is a foam cylinder (wall about 1cm thick) with one end closed.

A replacement is a similar amout which, even by volvo standards, is outragouus.

What can we use to replace it?

Any reasonably porous material would do - a bit of oil soaked cotton sheet, maybe. The air cleaner isn't exactly critical on a sea boat. The Volvo MD22 (50hp - as fitted to numerous 11 to 15m boats, including mine and a few other forum members) doesn't even have an air cleaner as standard.:)
 
Plan B

Quite a few sailors seem to be replacing pricy factory air filter elements with an appropriate K&N model. There are some DIY threads on doing this for Universal Diesels. Perhaps this would be a better long term solution.

:confused:

We have not done this change for our 20-year-old diesel, but will probably do so before ever buying another overpriced foam filter element for our Universal.

Agree with above poster that, historically, an air filter was not considered vital... but what with dust from V-belts, and sometimes the bits of foam falling off old sound-deadening material, it's good to have filtering. And then there's the floating hair from the ship's dog or cat! :)

Good call! "Performance Sailor". There is a Halfords near us and I can even look for FREE!

And if I get a big filter, I can then cut it down and have some material left over for spares!

"RCYC" Royal Cornwall YC by any chance?
 
the material from cooker hoods is good but not the activated charcole ones.


attaching it is fun as most glues attack the foam, dont apply to the foam side only the steel and use sparingly as it will block the holes.

Barring accidents, this component lasts indefinitely. Cannot understand the reluctance to buy (even though expensive) but to bodge!

Anyway it is your engine.

One reason it may not last for ever is if you try to clean it! I decided that a rinse in diesel fuel would be helpful, as with old cars that I have owned. The diesel attacked the foam! Not a good idea.
 
I never cleaned mine in the 19 years I had it and it is still there! I have doubts that it actually does anything, but maybe my boat is just too clean.

If you could see the boat, I hope you would think that there are no 'bodges' on it - I'm very particular about stuff as I recognise that it is me that it is going to let down if it is not right.

However, taking your other post, the filter has some small damage, that will probably, as you suggest, actually make no difference, as the engine bay is clean as a whistle but you never know just what might get into it.

But I do have a real antipathy to paying Barrus prices (the UK Yanmar importer sets the prices which the 'dealers' all slavishly follow) when a) there are always lower cost options, often made by their supplier and sold under their own name and b)the same items cost a lot less elsewhere in the world.

So principles kick in.

I am always happy to pay a fair price but not a silly one. Hence the time spent making a reasonable assessment of the options and choosing to do some work myself, and learn a lesson while I am it. Better placed to make that repair out at sea if ever I need to.

Lesson learned this time? Be wary of yard winterisation programmes - may be better to do it myself next time!
 
Don't disagree with your principles. BTW the prices are set by Yanmar Europe, not Barrus - not that it is an excuse for prices being higher in Europe than in the US.

However, there are some things where it is not worth the effort to try and find an alternative because you so rarely need it and there is no viable alternative. Different on service items that you consume regularly - although these are usually better priced from Yanmar than non-service items.

I think I am typical of Yanmar owners. In the 17 years I had the engine the only non-service items I used were seals, fastenings and gaskets for the front cover after salt water corroded the aluminium casing - total less than £100. Don't think the dealers got rich on me. I just hope my new Nanni does as well.

Nope, other side of the spinning globe....
Rose City Yacht Club, Portland, Oregon

Odd trivia: one of members was land touring in Ireland and used his reciprocals to visit the Royal Cork YC. They told him that they are the "oldest YC". I have no idea if true. Our club was founded in the 1930's, so we are rather "young".
:)
We have a 150 boat moorage, floating clubhouse, and own our upland area -- enough for a parking lot. No paid help - members do all the work and we have our own dredge to cope with ever-accumulating sand.

It's true. Even more surprising is what a royal yacht club is doing in a republic.

As to filter materials, you probably can't go wrong with K&N, a well-established and reputable company. I'm not familair with their products for diesel (sorry, fueltrader, gasoil) engines, but their petrol engine products require perodic cleaning and impregnating with their special oil.

Tranona's distaste for 'bodging' suggests he has never sat on a chair, at least without a safety harness. What an upstanding fellow he must be. What on earth did bodgers do to become such a maligned species?

Maybe this: "bodging can also refer to a job done of necessity using whatever tools and materials come to hand and which, whilst not necessarily pretty, is nevertheless serviceable. Bodged should not be confused with a "botched" job: a poor, incompetent or shoddy example of work, deriving from the mediaeval word "botch" - a bruise or carbuncle, typically in the field of DIY."

On a boat, it's good to know the difference.
 
I wonder if the connotations of the "bodger" comes from the fact that the chairs were made of green wood, so the joints were fairly loose so tightened as the wood dried? of course, some never became good and tight...

Another potential source of spares for Yanmars is the industrial engine users and their suppliers. We once marinised a Yanmar twin, same base as the 2GM, which had been removed from a written off Thermoking refrigerated trailer. They're used to drive the chiller compressors. A Thermoking dealer supplied us with oil filters and spare hoses at a fractio of the price of Yanmar marine parts.

I have also used KN filters for air intakes, the ones sold for breathers are big enough as the throughput is fairly small by comparison.

Yes, I saw Monty Don in the wood on TV last week making chairs out out of green wood!

Using your distinction, you would need to determine whether replacing the "proper" filter with a piece of cooker hood foam is indeed "serviceable". I don't know as it looks a pretty weak affair to me - but as I said seems to last the lifetime of the engine and is readily available. So, despite the price it is not the sort of thing worth agonising over.
