NISSAN Pathfinder Manual Transmission Rebuild Page 3
Measuring Transmission Gear End Play in my 1994 Nissan Pathfinder.

  1. The Pathfinder's gears are exposed and ready for gear end play measurement. This is the stage where I find out why I couldn't get it into first gear or reverse.

    This is incomplete at best. A service manual is essential. If you are following along, this is page MT-39, Manual Transmission section of the Nissan Pathfinder Factory Service Manual.
    But first, lets pay some bills:

    1. Measure first gear end play.
      Factory spec: 0.23 - 0.33 mm.
      Mine: 0.25 mm.
      Note: I am not pointing to first gear, I am holding up one finger to remind myself which pic was for which gear. The feeler guage is in the position to measure first gear end play.

    2. Measure second gear end play.
      Factory spec: 0.23 - 0.33 mm.
      Mine: 0.20 mm.

      second gear end play

    3. Measure third gear end play.
      Factory spec: 0.23 - 0.33 mm.
      Mine: 0.25 mm.

    4. Measure OD counter gear end play.
      Factory spec: 0.23 - 0.33 mm.
      Mine: 0.30 mm.

    5. Measure reverse main gear end play.
      Factory spec: 0.33 - 0.43 mm.
      Mine: 0.35 mm.

    6. Measure counter gear end play.
      Factory spec: 0.10 - 0.25 mm.
      Mine: 1.0 mm.

    7. Measure reverse idler gear end play.
      Factory spec: 0.30 - 0.53 mm.
      Mine: I do not know how to measure this while it is out of the case. Later I figure out how to measure it in the case.

    8. So this tells me I have to pay close attention to second gear and the counter gear because they are out of spec. I will also check the bearings because of a high pitched whine while driving. I will also check the reverse gear and syncro because it is hard to engage reverse.

    9. Next I sold out to make 02ยข so I can fulfill my lifelong dream of owning a 1986 944 with blown head gaskets.

      But no minivans!

    10. Then I finished my beer.
