No - The crankshaft bolt will loosen counter-clockwise. Because the crank bolt is so hard to remove it can seem as though it is reversed threaded. The crank turns the opposite direction that is used to tighten the bolt. For the crank bolt Lefty-Loosey (counter clockwise), Righty-Tighty (clockwise) apply here. The crank bolt is tightened to 87 ft/lbs of torque. It took more then 87 ft/lbs of torque to loosen my crank bolt. The manual says to apply a drop of motor oil when reinstalling the bolt. An Harmonic Balancer Pully Holding Tool is used to hold the crank while working with the crank bolt. Holding Tools can be found on the internet for $20 to $73. There are two sizes, 45 mm and 50 mm. For a 1990 model year the size is 50 mm. I made an Harmonic Balancer Pully Holding Tool by tack welding a 2 foot length of 1 1/2 inch by 1/2 inch piece of stock, for a handle, on a 2 inch (50 mm) hex nut. The nut fits into the pully to hold the crank and the socket, used to turn the crank bolt, fits through the nut.
Not all crankshaft pulley bolts are left hand thread. In my experience if it is a left hand thread the bolt head normally has an L stamped on it to notify the direction of thread
No. But it's tight.
no it is not left handed,some times just a real pain getting off.
Right hand thread
1998 Nissan pathfinder crankshaft pulley bolt is right handed.
crankshaft pulley bolt is left hand thread,so it will come out opposite direction to normal bolts
i am sure its left hand thread
standard thread on the 99 model with 4.0 liter.
More than likely it is right hand thread.
No. It is standard thread. (righty tighty, lefty loosey)
most crankshaft pulleys have a left hand thread. this means it turns opposite direction or clockwise to remove
No,it is right hand thread.
Take the bolt to a machine shop and they can tell you . if you dont have it most metric auto bolts have a 125 thread pitch but i dont know the diameter.
It is right hand thread. Turn counter clockwise to loosen.
remove 22mm center bolt its regular thread there are 2 threaded holes in pulley you will need the right pulley remover with the right bolts for the pulley you can get this at most parts stores make sure to not mess up crankshaft bolt threads
No. It's regular righty tighty, lefty loosy.
NO, just turn it to the left and it will come right off.
No it is not. The bolt on the pulley is but the tensioner mounting bolt is a T55 torx bit head with the standard thread (right/tight left/loose).
No. Righty-tighty, lefty-loosey. Just removed mine and looking for the specs on the thread as it looks like the last person in put it back in with a hammer-drill and broke some of the threads on the bolt: hence, I need to run a bottoming tap into the crankshaft to make sure these threads are still good.
Left are reverse threaded.
No it is not reverse thread. The passenger side rear spindle is the reverse thread on 88-93 festivas.
My grandmother sews with a needle and thread. She lost the thread of the conversation. Help me thread the rope through the pulley. The girls was threading beads on a string.
Hey, yes the Idler Pully nut is reverse tread (you have to turn right to loosen this) this is because you turn left to loosen belt tension. I believe this is true for a lot of GM engines.
