are you honing the bearings?? how are you intending to do that? the rods may be swapped around as long as you check over the engine when built. (the rods will not be all the same length, so you should swap them around until all the pistons are equally far from the deck at TDC |

On the large bore engines the rods are "handed", ie, they are offset top to bottom along the line of the crank.

Yes, but the rods are offset on a standard 1275, look at them and you will see they are "cranked" from top to bottom, so two go in one way around and the other two, the other way around...... Schrödinger's cat - so which one am I ??? |

The do however have an offset Small bore rods on the other hand, are handed, there are two part numbers, one for left and one for right handed rods

The rods in the 998 are mirrored(?) Two of each. On 13th Jul, 2012 Ben H said:

Is it possible to determine which go where? Thing is, is it much of an issue anyway where im having fully preped con rods and crank with new bearings? Your have to bear with me am new to this lark

It wont matter where the rods go, they will only fit in the engine one way anyway, two with the offset to the right and two with the offset to the left.

So 4+3+2=9

would it matter if the rod caps are put on back to front??? The notches in the big end journal for the bearing shells are both on the same side, as oposed to one either side of the rod On 26th Oct, 2004 TurboDave16v said:

OK so no real issue there as I can determine which way the caps go on by looking at the notches. 1310cc TWINK - T Conversion |

So what you are really saying is that a left handed spanner is can be used as a right handed spanner, yet they are the same
Something termed as 'handed' means it was designed to be used one or the other way, not both small bore rods are 'handed'

And WTF is a left handed spanner ???? A spanner that writes with it's left hand? Depending on the pistons used (especially if they have a front or thrust face), once they are on the roads the assemblies do become handed.

They are physically identical but go in, two the one way, two the other..... So they look like they are handed, although it's just putting the offset opposite ways around..... And WTF is a left handed spanner ???? BTW, obviously I agree the small bore rods are physically handed becuase the caps are not at 90 degrees, but..... Sorry, bad mood, my bottle of argon just ran out in th middle of my final weld....  You need to take one of these
