Identifying Your Mazda 2.0L & 2.2L Engines

Saturday, March 1, 2014

Identifying engine variations is always a challenge to even the most seasoned parts persons. It is the job of the engine remanufacturer to ask the appropriate questions that will identify the engine in an easy and timely manner. Some remanufacturers rely on model and serial number information alone, which is a sure way to create a world of problems. Although this model and serial number method is the easiest for the parts personnel, it is also the least profitable for all of the parties involved. With the cost of freight and the low margins in the reman and forklift businesses - every order must be flawless in order for all parties to make a fair profit. Believe it or not PROFIT is not a dirty word. At All Industrial we focus on what our customer can physically see that will identify the correct engine variation 100% of the time. For this reason, I feel that it will be very helpful to focus several Tech Talk articles on identifying popular late model engine variations. The following article will explain the easiest way to identify the different variations of the Mazda FE, F2SA & F2SM engines and the easiest way to differentiate between the three.

The Mazda FE and F2SA are used by Hyster and Yale with the F2SA being the later model. TCM also used the F2SA belt drive but more commonly used the F2SM chain drive, which has a different style cylinder head. The engine block of all three engines has an FE or F2 stamped into the corner of the deck of the block. The problem is that once the block is resurfaced the stampings are machined off. The other problem is that it is hard to find this tab on a dirty engine loaded with accessories. The following will breakdown each engine variation to allow for easy and accurate identification.

Mazda FE – (2.0L Timing Belt)

  • On either the black plastic dust cover or on the inner plate behind the cam sprocket will be casted in 2.0L
  • Three crankshaft variations – shorter stroke than the F2 (3.386”)
    • Pin Type – (oldest) 1” crank nose with an alignment dowel pin instead of a crank key. This style crank uses a tapered wedge that is in the crank sprocket, which has a threaded I.D. for a special removal tool.
    • Short Nose Keyed – (middle) 1” crank nose with a crank key.
    • Long Nose Keyed – (late) 1.900” crank nose, which has a wedge in the hydraulic pump drive hub.
  • Uses the same cylinder head as the F2SA, which will have a casting number of: FE-79 and/or F8, which will be directly casted on the intake side of the head.
  • The FE oil pump is located in the lower front area of the engine and houses the front crankshaft seal. It has four (14mm head) oil pump bolts.
  • The FE uses a belt tensioner only

Mazda F2SA – (2.2L Timing Belt)

  • On either the black plastic dust cover or on the inner plate behind the cam sprocket will be casted in 2.2L
  • Two crankshaft variations – the F2 crankshaft has the same journal sizes with a longer stroke (3.701”) than the FE crankshaft.
    • Short Nose Keyed – (middle) 1” crank nose with a crank key.
    • Long Nose Keyed – (late) 1.900” crank nose, which has a wedge in the hydraulic pump drive hub.
  • Uses the same cylinder head as the FE, which will have a casting number of: FE79 and/or F8, which will be directly casted on the intake side of the head.
  • The F2 oil pump is located in the lower front area of the engine and houses the front crankshaft seal. It has three (14mm head) oil pump bolts.
  • The F2 uses both a tensioner and a belt idler.

Mazda F2SM – (2.2L Timing Chain)

  • This engine only has one style crank- shaft whose crank nose is different than all of the crankshafts listed above. However, it does have the same stroke (3.701”) as the F2SA crankshaft.
  • The timing chain is enclosed inside an aluminum front cover, which extends upwards also covering the cam gear.
  • Used only by TCM.

This information should be helpful in ­identifying, which engine you are working on. Whether you are looking up engine specifications or ordering a reman engine, it is good to know what you have.
