Perkins 4.107

Well, now that the fuel system on my Perkins is servicable, moving on the the next job - replace the air filter...

But - there is no air filter currently. Went down to my local perkins supplier, and they dont have any documentation for the 4107 - they did show me some parts for the 4108 which look totally different, square rather than circular housing.

So my questions to you guys are - does the photo of my air "filter" housing look like a standard 4107 install?

Is it usual to run these with no filter element inside.

It would be really great if somebody could post a picture of a 4107 showing the filter element correctly installed- even better if somebody can give me part number and where to get a filter (local perkins guy reckons he couldnt find a part number or stock code)

there is a manual for these engines and 4-108-- one can be found in the leaky teaky yacht club on yahoo groups and one can be found in the fuji owners site...when we installed my 4-108 after po broke the 107, we found the air cleaner from 4-107 works great on the 108. we didnt use any element inside ita s the engine is inside --way deep inside the boat and no dust or diet goes there..not like a tractor in a field....is cleaner----so we didnt add anything to the filter unit, just placed the red round unit on the nice blue engine.

G'day Billwa,
The 4107 does not have a filter as used in automotive circles, a metal screen drops into the manifold top to act as a cold start flame arrestor &to stop larger objects finding a way in. If not regulary cleaned the the screen clogs up with a lint oil mix, many operators throw it away as you have discovered, because running conditions are so clean in most boat engine rooms it is not needed unlike a ag situation .You will not find one any parts place, other than a machinery wreckers. Too old.

I have seen people try to-re-engineer their "silencers" with foam......then they wonder why the boat loses power and blows black smoke.......

I've a friend who adapted a K&N system to his 4108, and it runs and starts fine with no smoke and it's lots quieter too. I'm thinking of doing the same thing.

Hi Johnar/BIGMAN

May be interested in the spare part, but at the moment would love to see a photograph of your air filter so I know what I am missing from my engine (if anything).

Oh, by the way, I am based in West Australia.

Yes.

Yes. (marine application)

There are LOTS of different application for these engines, so different configurations as well as different components. As I pointed out in your fuel line thread, my starter is is on the other side of the engine from yours. The diff you are seeing (between the 4-107 and the 4-108 ) in the pictures means nada..... zip... didley squat.

My boat had a badly negeleted 4-107 when I bought it. It has a 4-108 now. Only the long block was changed.

4-107= wet cylinder sleeves. 4-108 = dry sleeves.

I added a K&N filter to replace the screen on my 4-108. It is quieter and even living in a "clean" envioroment on a boat I like to have a true filter. The link below should take you to the specifics I used but if you search the forum for perkins 4-108 air filter this should come up.

LOL, that will make it easy to find...

When we built our house, we had a female electrical contractor. She had all her tools painted pink - she said that the guys she hired hated to use them, and somehow the tools rarely walked off the job site.
