Kalto virzuļu un cilindru izmērs

[BriinumsBo]

Atnāca Wiseco virzuļi, bet nav skaidrīte uz cik jāborē cilindri.
Virzuļi itkā paredzēti 86.5mm (0.5mm virs standarta). Virsū rakstīts "Bore: 0.000", iekšā kastē specifikāciju lapa, kur lielākā daļa nav aizpildīta
Nomērīju virzuļus - 86.46~86.47, t.i 0.03mm mazāks par vajadzīgo cilindra izmēru.
Wiseco mājaslapā FAQ raksta, ka viņu virzuļiem (vispārīgi, nav noteikts kuriem) vajag 0.004 collas izmēra starpību (piston-to-wall clearance) kas ir ~0.1mm..
Vai cilindri jāborē uz 86.50mm vai uz teiksim 86.56mm?
Kautkādā vispārīgā aprakstā par kaltajiem viņi raksta šitā:

vajaga ņemt bloku, virzuļus un braukt uz kantori kur borē blokus. domājams ka viņiem vajadzētu zināt kas tur un kā

Ja clearaance ir 0.1mm, tad dirku vajag 86.5+0.1=86.6

Answer from my USA collegue:
Martin, Sorry, for some reason the clearance isnt listed on the 865mm sheet. The sheets for the 86 & 87 list the minimum recommended clearance as .0025” (.0635mm). For higher boost applications it should be increased to .003” (.0762mm). The clearance should be added to the piston diameter and the bore set at that diameter. We don’t have a chart listing thermal expansion rates. Keith
Best regards.

parasti normaalos ceshos zina kas cik ir jaahonee...
daudzos ceshos veel piekopj vecaas metodes, ka honee tik ilgi, kameer saellots jaunais virzulis, pats ar savu svaru izsliid cauzi izsliipeetajam cilindram...
Taapeec jau arii lielaakaa dala cehi prasa liidzi virzulus...

vel atbildeja:

1&2) Minimum recommended means that the clearance should not be less than .003”. Maximum clearance would be .0035”. The major diameter of the piston should be measured at 90 degrees from the pin at the bottom of the skirt. JE clearances are not the same as ours. We each have our own designs that require different tolerances. The clearances mentioned in our FAQ refer to Wiseco domestic American applications which require a little more clearance.

3) The coating is .0005” thick and it is permanent. It won’t wear off under normal conditions.

The .080mm will be good. You should have no issues.

Regards,
Keith
