I like finishing jobs; leaving something unfinished anyones me. Not having been able to torque the prop shaft bolts was one of those unfinished tasks. I was waiting with that until I had a working handbrake, because to torque the bolts up, you need to be able to lock the prop shaft so it doesn’t turn.

Torqued prop bolts

The manual (v1.2 and v2.0) calls for thread lock, so I used Loctite 243 on the bolts before putting them in, making sure they are tight before the thread lock has dried.

Fitting the bolts is simple: find the best access to the bolt (for me that was from underneath with the tools I had available), lock the drivetrain with the handbrake and gear selection, torque the bolt, then release the handbrake and put it back into neutral, and rotate the prop shaft to gain access to the next bolt. I torqued the 12 o’clock and 6 o’clock bolts before the 3 o’clock and 9 o’clock ones to 47 Nm torque as per manual (v1.2 and v2.0). This tightening sequence is good practice, because you can’t torque all bolts simultaneously. Diagonal or opposite torquing allows uniform preload across all bolts.

Tools Used

  • 8mm hex 3/8″ drive socket
  • 8mm hex 1/4″ drive socket
  • 1/4″ drive extensions (selection)
  • 3/8″ drive ratchet
  • 3/8″ drive torque wrench
  • Side cutters (where used to remove temporary tie wraps holding the handbrake cable)
