Search for Piston for Model A/B 1929 86.4 + 0.040"

[max.treichler]

I'm looking for a piston for Model A / B 1929 sv 557cc.
The bore must be 86.4mm +0.040 "= 87.4mm.
I already ordered one in May 2017 at Draganfly.
But unfortunately they still does not deliver.
Does anyone have such a piston?
Or could i use a piston from a later model?
If the diameter of the gudgeon pin is smaller, i can use a bush in the connecting rod.
Is the compression height the same?
Thank you for the help and tips.

I can only help you with NOS 500cc sidevalve pistons +20 and +30 so you would need a liner to use it.

I think VW Beetle has 88 mm piston, maybe it can be modified.
I have Datsun 160 J 84 mm piston in my VH, which was overbored
by previous owner.

Hallo Max,

ich habe einen Kolben für mein Modell B direkt bei JP-Pistons in Australien bestellt. Das Ganze hat vor 4 Jahren mit Versandt 130 AUS$ gekostet.
