Which Loctite On The Alternator Nut?

  1. Which Loctite on the alternator nut?

    Thanks
     
  2. blue I would say
     
  3. a controversial one unfortunately, have used 262/268/272/277/290 in the past and none have come loose after application but (apart from 290) will breakdown due to oil contamination in time and have noticed this on stripping. Loctite 290 is listed as oil tolerant (medium/high strength) and probably your best bet for peace of mind but may need heat to disassemble according to manufacturer notes but i've never had a problem when used with hot oil.

  4. I pity the poor s*d that has to get mine undone - I used 638 - that will not come undone easily without a bit of heat.

  5. Just waking this one up, manual says use Greese not locktite

  8. That's lubricate the mating faces of flywheel, washer and nut face.

    Look at the torque spec charts..
     
  9. The extract from the workshop manual above appears to be from the IE manual.

    The workshop manual that is readily available online for the carbed SS shows a washer which has to bent as per a tab washer.

    For some unknown reason the carbed SS parts manual doesn't appear to show the washer or nut in realtion the fitting of the alternator, but they do appear to be under the timing gears section.....shown as a lock washer.

    However, I think there is a suitable approach to the question asked by the OP.

    If you don't want the alternator/flywheel to come loose, use Loctite.
     
  10. Sorry this is a 2002 ST4S

    Engine Oil is on the torque spec
