CAT 3208 motor, hvordan oppleves denne motoren?

[Kjetel]

Hei, lurer allerde på å bli noen fot større. Har tittet litt på en Pairline og en Princess, begge med CAT 3208 375 hk. maskiner. Har ikke prøvekjørt noen av dem enda. Hvordan er disse motorene med hensyn til gange, røyk, holdbarhet osv. Motorene er fra ca 1990 og kjørt 1700/1100 timer.

Har nå TAMD 41 A maskiner, og de røyker som kjent en del, og ønsker ikke å ha like mye røyk fra min neste dame. ( Selv om mine motorer er av den snille sorten med tanke på hva jeg har sett at de kan. )

Faren min har en nyoverhalt 3208 375hk i båten sin. Den har veldig stille og rolig gange med lite vibrasjoner. Man hører jo såklart selve motoren, men selv med eksos uten lyddemper er det overraskende lite lyd bak båten. Kan ryke en del like etter oppstart men dette slutter helt når du får normal driftstemperatur. Ved normaltemp ryker den nesten ikke i det hele tatt. Nå har ikke vi hatt denne motoren lenge, men førsteinntrykket er ihvertfall veldig bra!:) MYE kraft! hehe

 

Mvh Tomzern

Flott motor.. diesel V8 hvis jeg ikke husker feil.. Men den er en steingammel konstruksjon som opprinnelig ble levert i traktorer.. mener den er fra 1967 eller rundt der.. ble opprinnelig også lagd som bruk og kast motor men viste seg og være rett så trofast

 

Motoren ble faset ut 1999 grunnet at den ikke klarte utslippskrava.. noe man forstår når man ser på hvor mye diesel disse skal ha vistnok.. etter signende så renner det igjennom.. altså i overkant tørst..

 

Deletilgangen kan vise seg og være begrenset etterhvert.. ikke akkuratt vp med sjapper rundt hver odde.. (som ofte trengs )

 

Sikkert fler som kan noe om denne gulklumpen.. et raskt søk på google gir deg bøtter av svar

 

en annen ting.. hvis du må kjøpe deler fra merkeverksted så hver forberedt.... skulle tro at delene var av guld og diamanter.. vp blir lillegutt i forhold

Her er historien rundt motoren og litt til

 

Catepillar 3208:

 

 

Although its original concept was a cheap throw-away engine, the Caterpillar 3208 engine has been used for many applications. Perhaps the most popular application has been to power marine craft, where it has proved to be a reliable engine, with some boats clocking up thousands of running hours.

 

Introduction to Caterpillar Tractors and 3208 Diesel Engines

The Caterpillar Company was formed in 1911, after some years of research and development. It reputedly took its name from a farmer who was watching a test run and stated that it moved “like a caterpillar.”

 

Caterpillar engines have proved to be reliable and cheap, and the 3208 is particular suited to fitting into all sizes of boats. An RNLI Lifeboat near Drogheda in Ireland is powered by twin 3208 turbo-charged diesels – such is their reliability.

 

This is an article on diesel engines and in particular the Caterpillar 3208 diesel engine and its application in modern times. We begin with a short history

 

 

of the Caterpillar Company and move on to its assets.

 

 

Short History of the Caterpillar Company

As we saw in the introduction, the Holt Caterpillar Company was founded in 1911. It produced tractors and exported them to Canada, Argentina, and Mexico, gaining much experience which it used during the First World War.

 

During the war Caterpillar Armored Tractors were used extensively to tow artillery pieces such as howitzers. It wasn’t long before the British Army Engineers saw the potential of using the track driven tractor as an armored tank.

 

After the war, the depression set in and Holt Caterpillar was forced to sell out to a competitor named Best who scrapped the production of large tractors in favor of smaller agricultural ones. He formed the Caterpillar Company in 1925. All the livery including the engines was painted yellow, distinguishing it from its competitor’s machines.

 

During this time the engines were developing apace, and during the Second World War found fame once again when their diesel engines became the preferred engine as opposed to a gas (petrol) one.

 

Since then Caterpillar engines have become world famous. I worked on a couple of 3208 marine diesels over the years, and although they were very basic, I liked them.

 

They were reliable being easy to strip and repair as there was always plenty of spares around, no matter what part of the world I was working in.

 

Nowadays spares for the 3208 model are still available from various outlets; some EOL still supply, in fact you need to go there for certain gaskets and valve-stem oil seals and some spares. Facebook has at least four suppliers of reconditioned engines and used and new spares for this engine.

 

Typical Applications for the Cat 3208 Diesel Engine

Although the 3208 has been discontinued (1999) there are many still in service; the most popular applications for these engines are listed below:

 

•Marine

The Caterpillar TA 3208, 375 HP will drive a 13T boat along at 35 knots.

 

Marine applications include main and auxiliary engines on the following vessels.

 

•Cruise ships (aux)

•Ferries (aux)

•General cargo ships (aux)

•Yachts and pleasure cruisers (main)

•Offshore (aux)

•Tugs (aux)

•Fishing boats (aux)

Other applications for the 3208 caterpillar engine include:

 

•Government Service Vehicles – garbage trucks, snow ploughs and blowers, delivery trucks and school buses.

•Agricultural Machinery – combine harvesters, tractors, sprayers, and fork lift trucks.

•Industry – excavators, bulldozers, cranes, low-loaders, articulated mining trucks, and backhoes.

•Power Generation – emergency generators and temporary and permanent industrial power station standby gensets.

Design of the 3208 Diesel Engine

The original caterpillar 3208 diesel engine was a 225hp, 636 cubic-inch capacity V8 design. It did not have cylinder liners, but many engineering companies would re-bore the blocks and fit oversize pistons and rings rather than throw the engines away. (They were known as “throw away engines,” which the makers claim was one of the design criteria.)

 

The 3208 emerged in 1973 as a turbocharged version but in 1981, major design mods such as stronger internal rotating parts, three-ring pistons, and beefed up oil and water pumps. The cooling system was also upgraded to include a bigger heat exchanger and seawater pump to cool the engine oil, exhaust manifolds, and turbochargers with the expansion tank and thermostats also being modified.

 

It was used in many applications but soon became a firm favorite with the yachts and pleasure boats fraternity, with the larger vessels having twin turbo-charged engines fitted.

 

Unfortunately, the engine was a bit of a gas guzzler and failed to meet the new internal combustion exhaust emission laws which were due to come into force in the new millennium; therefore it was discontinued in 1999.

Tørst.

Tørst?

Den er ihverfall ikke spesielt mye tørstere enn allt mulig annet som sitter i den type båt. Den bruker i snitt

20 liter pr. 100 HK du tar ut av den. Jeg har 3208TA 375 og den synes jeg er veldig bra. Cat har også deler stortsett

over hele verden. På forumet Boatdiesel.com (koster 25 usd) er det veldig mye om denne motoren (og mye annet, som man kan smurfe i.:D

Der er 375 versjonen en av de bedre versjonene av 3208. Husk motoren har 10,4 liter volum, så den er ikke mye trimmet iforhold til mye annen diesel idag.

Veldig bra motor. Ble levert fra 150-210 Hk uten turbo, og fra 250 Hk og oppover med turbo og intercooler med maks 425 hester. Den beste motoren er vel 375 hesteren, og det er tynt ut lite hester av den når en ser på det store slagvolumet. Bare de får sine olje og filterskift, så går de som bare det. Ryker litt på tomgang på kald motor, men det er det flere som gjør.

HAR SELV EN 210 HK OG ER MEGET FORNØYD ,BARE DEN FÅR LITT STELL MED OLJE OG FILTER ER DET INGEN ANNEN TING SOM GÅR I STYKKER, HAR HATT MIN I 5 ÅR NÅ OG DET ENESTE JEG GJØR ER OG SKIFTE FILTER OG VASKER OG STELLER MED DEN, DET ER LITT STØY MEN KAN MAN BRUKE DE TØNNENE JEG HAR SETT NOEN MOTORER HAR SÅ ER DENNE OGSÅ STILLEGÅENDE.FORBRUKET ER CA 2 LITER PR NAUTSK SÅNN OMTRENT PÅ CRUISING SPEED.OG SET ER ABSOLUTT INGEN VIBRASJONER PÅ MOTOREN.
