Noh, laitan tähän tällaisen päivityspostauksen tuon ö-pumpun ruuvin tienoilta minkä netistä löysin, tuntuu ihan järkevältä?? Hä?
The oil pump pulley bolts have a reputation for shearing off usually resulting in a broken belt and consequent top end damage. Whether this is due to an over-tensioned belt or to an under-rated or over-torqued bolt is open to debate. In any case, they should be replaced with new bolts at each timing belt change. [Karl-Dieter Haugk] The replacement bolt is Volvo p/n 948472, an extra strong metric 10.9 class M10 x 1.5 mm (standard thread) x 30 mm long bolt including a flat washer (Volvo p/n 960148). This appears to be an upgrade from the original class 8.8 25.4 mm long bolt which should reduce or eliminate the incidence of failure. Use the new, higher grade bolt as this is a critical engine part.
Kulmamies lienee siis jäljillä..

Laitetaan tähän oikeen vahvennettuna lainaus tuon jutun lopusta niin menee varmaan perille.
Use the new, higher grade bolt as this is a critical engine part.Eli käytä uutta(10.9 lujuusluokan ruuvia), volvolla osanro Volvo p/n 948472. Prikallekin näyttää olevan osanumero..

Sopinee siis tavallinen 10.9 30mm pitkä ruuvi prikan kanssa?
Niinkuin Xuppo:lla on.
