Title: piston application Post by: my8thholden on April 19, 2020, 06:50:42 AM Any one have a old Repco catalogue and can look up piston WX1872P ..I imagine it will be under Holden listing for early grey engine ,It may be under a numerical listing and say for example Chevrolet or Vauxhall ,if either way its found I would appreciate the details ..thx Vern .

My catalogue lists; FX to FC std bore of 3.000 as WX1558 FB std bore (and FX to FC overbore) of 3.0625 as WX1871 FX to FC over bored to 3.125 as WX1851 (https://i.postimg.cc/34LMy5Pf/C36-CFB9-D-F959-4691-9-E75-C630261-C8-CBC.jpg) ($2) Ken Title: Re: piston application Post by: Harv on April 19, 2020, 10:58:11 AM The 1966 2nd edition Automotive Parts Catalogue does not list WC1872P for anything (Austin, Chrysler, Datsun, Ford, Hillman, Holden, Humber, Isuzu, Morris, Nissan, Rambler, Standard, Toyota, Vauxhall, Volkswagen and Wolseley). It lists WX1558D for FX-FC, WX1871C for FB-EJ, and WX1872A as a “Repco 3-ring Piston” for FB-EJ.
The Repco Replacement Parts to suit Holden 1948.1965 catalogue shows the same. You sure it’s a “P” and not an “A”? If the slug is 3.0625” bore and 3-ring then it may be FB-EJ.

Repco rings verses ACL rings Verses Perfect Circle rings kept beliefs and preferences alive ,3 piece segmented oil control rings as opposed to one piece ..I think that's why the choise was provided..also pre fitted rings got around the problem of the guy who would break one ring when assembling..engine reconditioners usually have a few boxes of raided rings tucked away ...cheers Vern
