I am working slowly but surely through my new top end.
I am trying to do as much as possible to have a finished top end read to swap over so that I have minimal down time.
Learning as I go I shall be buying pistons and sending them with the block for rebore.
This leads me to my latest question.
Remembering that a little knowledge is dangerous my understanding is that pistons can come with pinch bolt or fully floating gudgeon pins, so I need to know which to order to go with my existing con rods.
From a previous head gasket faiure I took notes that my pistons are marked 11121 plus 40 thou (I did not make any notes as to an RS being present).
From what I can find referencing 11121, I have found.
Hepolite Pistons Application List:
Reliant Regent 8, 10 & 12 cwt three wheeler van 1948 - 52
Pistons: Alloy 2·20" Bore and 1·13/16" Length - Hepolite Ref. RS11121
Pins: 1/2" Diameter and 1·15/16" Length
Type: SC i.e. fully floating pin retained by SEEGER circlips
So my questions:
Does the 11121 reference therefore mean that I have the fully floating gudgeon pin type or can that reference be on either floating or pinch bolt types and if so is there any way for me to find out what type of pistons/rods I have without taking the sump off and looking up? .
Alternatively I guess I could take delivery of pistons minus gudgeon pins and have the pistons fitted etc and then take delivery of the pins once I have taken the engine apart.
Thanks as always
