Floating ones were original. I have heard some 998 press fit rods were used here but have never seen one. However, 998 A+ motors in UK are press fit. |

I the years I played with minis I only ever came across one 998 engine that had press fit Gudgeon pins. that was in a Deluxe. From Memory the rods were the same minus the bush. |

These press fit rods were Australian manufactured and only used for a couple of years. About 1968. Repco made the pistons and rings which are now obsolete. The little end size is a couple of thou bigger than the normal 998/1100 conrods when the bush is removed. Most people use the normal rods when doing an engine rebuild that requires pistons. |

I have a set of GR 80 thou flat tops . About a 16 mm pin. The rods I pulled out of the deluxe 998 are 20mm . There is no circlip present , they look press fit. Question : am I dealing with an odd set of rods ? Machinist has stalled so I need to organise this asap. All help appreciated  Sent from my iPhone using Tapatalk |

Q: Am I dealing with an odd set of rods? Looks like it. Get a set of the standard bushed 998/1098 rods. I have 4 here in Sydney but Matt Read in Brisbane would have a pile. PM 'theminiman' on here. |

If you are doing a proper rebuild you will be fitting new bushes in the rods anyway, so if you are going to use the pistons with smaller pin that need a small end bush why not just fit bushes in the rods you have and and have them machined and aligned to suit the pins of the pistons you are using. |
