--------------- END SUPPLEMENT ---------------
Reports indicate that the recommended thread lubricant for the connecting rod and counterweight bolts, Fel-Pro C100, is not readily available in all areas of the world. If Fel-Pro C100 is not available, 2P2506 Thread Lubricant can be used.
Regardless of which thread lubricant is used, it is important that a coat of thread lubricant is on the bolt threads and the under side of the bolt heads. This must be repeated each time the bolts are tightened. Also note that too much thread lubricant on the bolt ends should be avoided. If a bolt with too much thread lubricant on the end is screwed into a blind hole, hydraulic lock can occur. This can cause an incorrect clamping force.
