Pistons, Piston Rings and Cylinder Liners
Note before ordering a piston set or ring set from Somerford Mini: a set of pistons consists of four pistons complete with rings and gudgeon pins; a set of rings consists of sufficient rings for four pistons. Cylinder liners are supplied individually. Various piston upgrades (superior design and manufacture, different capacities and compression ratios) are also available from Somerford Mini, but are only listed in this catalogue in instances where they make a good, complication-free replacement for original specification pistons which are in short supply.
         
Pistons listed here are those for original 1275cc Mini engines - i.e. the 1275 GT engine built between 1969 and 1980, plus engines fitted from the resumption of 1275cc Mini production in 1990 onwards. If you have a 1980s Austin or MG Metro 1275cc engine in your Mini, the later A Plus pistons shown here may be applicable in some circumstances, but we strongly advise you to contact Somerford Mini quoting your full engine number before placing an order to ensure you receive the right pistons or rings for your engine.

Connecting Rods and Crankshaft
Connecting Rods 1969-80 (1275 GT)

9 BHM1136 ROD SET, connecting, set of 4 1 Standard fitment.
10 12G1506 ROD ASS'Y, connecting 4 Standard fitment; included in connecting rod set.
  12G1297 ROD ASS'Y, connecting 4 Alternative Austin 1300 GT/Innocenti item.
The 1300 GT/Innocenti rod design is lighter than, but as strong as, the standard rod to be found in 1275 GT engines. It can be easily recognised by its forging number 12G1298 and a small strengthening web across the rod between its flutes (just above the forging number). Ideal for inclusion in a tuned engine, this rod was historically speaking very popular. Somerford Mini still has a limited number in stock, but hurry - when they're gone, they're gone. When changing to a different design of connecting rod, it is of course imperative that all rods are changed at the same time.

Crankshaft
Crankshafts shown here are either assemblies (including main bearings, connecting rod bearings and thrust washers), or bare (without bearings or thrust washers). However, please note that new crankshafts may be supplied complete with bearings but other times not, depending on what is available at the time. Additionally Somerford Mini can offer a crankshaft regrinding service, usually carried out on your old unit. You should enquire on the current status of supply before ordering a crankshaft from Somerford Mini. The CAM6232 crankshaft, by the way, has rolled fillet radii on the bearing journals which vastly improve its fatigue life.
         
For details of the primary gear and its bushes located on the tail of the crankshaft, please see the 'Manual Gearbox - Primary, Idler and Drive Gears' section or the 'Automatic Transmission - Torque Converter and Housing' section in the Transmissions area of the Somerford Mini catalogue.

There are two distinct main bearing designs: the earlier 8G2391 bearings have locating lugs on the edge of both upper and lower halves, whereas the later BHM1574 bearings have lugs on the edge of the upper halves and in the centre of the lower halves. They cannot be interchanged in engines because the engine main bearing caps are unique for each design. 1275cc engines were not fitted by the factory in Minis during the 1980s; however many owners have chosen to transplant Austin or MG Metro 1275cc engines made in the 1980s into their cars. For the benefit of those owners, the change in main bearing design on the Metro power unit occurred in 1983.
