305 kampiakseli

[Teac]

Ongelma on kampiakselin valunumero 14088526, josta löytyy vähän kaikenlaista"tietoa".

Jos nyt menen ostamaan samalla numerolla olevan akselin niin onko mahdollista, että pieleen menee? Eli voiko olla niin, että samalla numerolla

olisi tehty erinlaisia akseleita 305 ja 350 koneelle?

Tämän mukaan 305 ja 350 oli sama kampiakseli

Tälläinen tieto löytyi kanssa

Although factory GM 305 and 350 cast cranks have the same casting number, they are "balanced" differently. A 305 application crank has a target bob weight of 1600 grams, while a 350 application crank has a target bob weight of 1850 grams.

Eli fiilailee parisataa grammaa pois

Just tuota vähän pelkäsinkin. viitteitä painotuseroon löytyi mutta en löytänyt sitä noin suoraan sanottuna, kiitos!

 

Millähän h...llä nyt voi sitten olla varma mitä saa; löysin yhden kaupan missä samaisesta akselista todettiin että "305/350",

muutamissa mainitaan 350, mutta osassa ei mitään.

Saa muuten viilata ihan tosissaan

Akselin valunumerohan voi olla sama mutta toisessa vaan koneistettu limput vähän pienemmiks. Luulis painavammasta saavan kevyemmän ainakin kun vie asinmukaiselle pajalle. Tulee samalla tasapainotettuakin. Toki hintahan muuttuu melkolailla...

Juu saahan siitä pois, mutta jospa ei ihan vielä vaivuta niin epätoivoiseen tekoon

IDENTIFYING ONE PIECE REAR MAIN SEAL CRANKSHAFTS

GM 5.0 & 5.7L (305 & 350 CID) Crankshafts

 

Identifying the Chevrolet 5.0 & 5.7L (305 & 350 CID) crankshaft used in various GM cars and trucks has not been made any easier since the introduction of the one piece rear main seal crankshaft.

 

Currently AERA is aware that casting numbers 14088526 and 14088535 are cast iron crankshafts used in either 5.0L (305 CID) or 5.7L (350 CID) engines. Again, GM is using the same crankshaft castings in two differently balanced engines. A steel crankshaft with the forging number 14088532 is used in the 5.7L (350 CID) Corvette engines.

 

Both engines are externally balanced and use the same counterweighted flexplate or flywheel and a non-counterweighted damper. Equally shared are the connecting rods which weigh 603-604 grams. The rotating (big) end of the connecting rod weighs 424 +/- 2 grams while the reciprocating (pin) end weighs

179 +/- 2 grams.

 

The weight for a 5.0L (305 CID) piston and pin is 646 +/- 3 grams, whereas a 5.7L (350 CID) piston and pin come in at 743 +/- 3 grams. The total bob weight for the 5.0L (305 CID) engine is 1815 grams in comparison to the 5.7L (350 CID) engine at 1916 grams.

 

AERA mrmbers have visually differentiated the crankshafts by the balance holes drilled into the front and rear counterweights. Machinists using these specifications should be aware that all of the measurements are approximate and may vary slightly from crankshaft to crankshaft.

 

The holes drilled in the 5.0L (305 CID) crankshaft front counterweight vary somewhat. There are either two 1 holes drilled to a combined depth of 2.563, or two similarly drilled 1 holes along with a third .750 hole drilled to a depth of

.125-.313. The rear counterweight is much the same with either two 1 holes drilled to a combined depth of 2.250, or two similarly drilled 1 holes along with a third .750 hole drilled to a depth of .188-.313

 

The 5.7L (350 CID) crankshaft's front counterweight has two 1 holes drilled to a combined depth of 1.188. The rear counterweight also has two 1 holes drilled to a combined depth of 1.563.

Multa saat 350 one piece akselin asevelihintaan, on Corvetten akseli joka kestää + 500 hv joten jää virivaraa.

Kiitos tarjouksesta! Yritän nyt ensin löytää 305:sen akselin, mutta palataan jollei ala löytyä.
