The difference between a steel protect and rubber sealing has got to do with greatest rpm. Presented the 10.8k rpm max alternator speed when Utilized in the kind four motor with 5400rpm rev limiter, double rubber seals will suffice nevertheless it's essential the bearings be sealed since the inside the alternator receives incredibly dusty, especially amongst the slip ring and its bearing.
Understanding this trick can turn out to be useful if The shop does not have the 1 you may need: just buy a differently clocked just one, choose it apart and "re-clock" it. (Make sure to retain the brushes in the event Try THESE Guys Out you make this happen: see Recommendations under within the re-assembly segment)
