What are Semi Finished Liners?
Semi-finished liners once fitted to the cylinder block require boring and honing to size. Finished liners are supplied pre-bored and once fitted may only require a light hone. Liners basically come in two different flavours: Parallel and Flanged. A description of these are below: Parallel Liner: As it says, the parallel liner is flat on all edges.

These are held in the block by an ‘interference’ or ‘press fit’. Meaning the liner is marginally bigger than the parent bore of the motor. When these are pressed into place, they may distort and conform to the shape of the parent bore. Available only in semi-finished. (needs to be bored to size) Flanged Liner: Yet again, as the name implies, these liners have a flange at the top.

This flange locates into a counterore cut into the top of the parent bore. These liners can be either ‘press’ or slip’ fit. Available in either; finished (pre-sized) or semi-finished. (needs to be bored to size)

  • 2 Alpha Letters AA
  • 5 numbers 12345
  • the letter “U” U
  • 5 more numbers 56789
  • 1 alpha letter L

you can also check our engine number guide link The later, older engines had their engine numbers stamped into the cylinder. A lot of people get confused with the casting numbers or the numbers off the Injector pump. Unfortunately this can not assist our sales staff with identifying your Perkins Engine if your unsure contact one of our sales staff.
