For crank bolts, the threads are “normal” and tight on the right and slack on the left. The R side cup is left-hand threaded with the most popular English BB standard, therefore you’re confusing them with BB cups. Alternately, the L pedal is always manually threaded when using pedals. For both, crank bolts have a standard R hand thread. However, Campy left both of the built-in bolt/extractors that came with its C-Record cranks connected into the arms. Therefore, a special Campy L hand threaded crank puller is required if you want to remove them and use standard bolts.

Crank arms have reverse threads, right?
You might need to spritz some penetrating fluid, like GT85 or Muc Off Bike Spray, to get your pedals started if you haven’t taken them off in a while. Once you’ve made a few spins and exposed a few threads, spray the fluid again, repeating every few threads, until the pedals are free. If you attempt to remove the pedal without a little assistance from grease or oil, you risk damaging a dry, corroded thread.
Tip 3
The left pedal spindle is reverse threaded, so keep that in mind. When facing the crank arm, turn it clockwise to remove the pedal. Turn it counterclockwise to loosen it; the right side is the typical side.
You must place an Allen key into the pedal axle directly across from the pedal in order to loosen it.
Steps to remove pedals
1. Turn your bike’s drive side toward you. This is the bike’s right side, where the chainset and chain are located. The crank arm should be turned to the third position.
2. Put a spanner between the pedal body and the crank arm on the flattened surface.
3. Using your hands to hold the brakes. To turn the tool counterclockwise, press your foot firmly down onto the spanner. We’ve discovered that utilizing your foot gives you more leverage and ensures that you’re positioned so that you won’t run into the bike’s sharp edges or lose your balance if the pedal were to suddenly decide to come loose.
4. After the pedal has been loosened, turn the tool in an anticlockwise direction to release the pedal.
5. Rotate the bicycle. You are now facing the left side, which is the non-drive side. 6. To make the crank arm horizontal with the floor, turn it to the nine position. 7. Align the crank arm with the spanner or Allen key. 8. Press down on the spanner with your foot. To loosen the pedal, spin the spanner in a clockwise direction.
How can a left hand thread be loosened?
You will undoubtedly encounter left hand thread as you navigate the car repair industry. The majority of threads are standard right-hand threads, hence tightening the aforementioned object requires twisting the nut or bolt in a clockwise direction (turning counter clockwise loosens).
There are times when using left-handed thread is necessary. Contrary to normal right hand thread, left hand thread stretches and contracts (turn clockwise to loosen left hand thread). When something spins, it can make right-handed goods fall apart, necessitating the usage of left-handed thread.
Left-handed thread is used in several fan clutches. Left hand thread lug nuts may be used on a car’s left side, especially on older and more powerful models. If you look at the studs, you will notice that the left-hand thread is indicated by a “L” on the end of the stud.
Someone accidentally overtightened the lugs in an effort to remove the wheels, which led to each stud breaking off. Although replacing the wheel suds is possible, it is expensive and time consuming.
Just remember to pause and think about why if you are having trouble disassembling something. Something is probably incorrect if it seems to be wrong. You might avoid hours of agony and hundreds of dollars with a quick phone call.
How should a bottom bracket be unscrewed?
There are left and right arms for the two-piece crankset, but the spindle is connected to just one of the cranks. The bottom bracket shell’s bearings are passed through by the spindle.
The left and right arms of the typical three-piece crankset include an integrated bearing and spindle.
Common bottom bracket shell threading is referred to as “English. The left-side cup has a right-hand thread that tightens in a clockwise direction and removes in a counterclockwise way. The left-hand thread on the right side (the drive side) tightens and loosens in the opposite direction of the left hand thread.
The less popular Italian has right-hand threading on both the left and right sides. In a clockwise and counterclockwise motion, both sides tighten. The marking on Italian threaded cups will read: “36×24.
A harmonic balancer bolt may be reused.
I’ve used them repeatedly and never had a problem. If you are concerned about it, apply a little blue loctite on it. The most crucial thing I can advise you is to apply silicone on the keyway. Additionally, the included bolt is simply for beginning the pulleys; do not use it. My harmonic balancer pulley remover/installer set works better for mounting the balancer than a bolt, thus I have a few of them that I’ve never even opened.
Without a crankshaft pulley, can you drive?
Depending on which pulley was damaged, the pulley’s effects (there are quite a few on a engine). If it were the crank pulley, it might ultimately break off and, if it does, it might cause quite a bit of damage if it did so while the engine was running. In fact, if the crank pulley and harmonic balancer fail and the engine keeps running, the crankshaft may sustain damage. That’d be a pretty horrible thing. If a fastener is missing, other pulleys may deform, which could harm the drive belt that rides on the pulley. It is not a good idea to put engine oil in the transmission; instead, the transmission should be completely drained. Try to avoid starting the automobile if you know there is engine oil in the transmission because doing so will taint the transmission even more and make it harder to remove the oil. If you haven’t driven it, which is again the best case scenario, just take out the transmission oil pan and properly let all the fluid drain out. You may need to perform a few drain/refill cycles. You can ask for the transmission fluid exchange service that YourMechanic provides.
Q: How do you remove a stuck crankshaft pulley?
Have you got a crankshaft pulley that needs to be removed right now because it’s stuck? What you must do is as follows.
To remove the crankshaft pulley bolt, one method is to use a three-foot breaker bar or a longer breaker bar. Make sure you use a strong breaker bar that you can try to bust the bolt with.
You might be able to break the jammed crankshaft pulley with a 1/2 or 3/4 horsepower impact drive that you can rent. Make sure to choose a plug-in type because reefing the bolt could take 8 to 10 minutes. Additionally, try lubricating the crankshaft pulley bolt to help it loosen up a bit. As you continue to hammer on the bolt, you can do this periodically.
Use the starter motor to loosen the crankshaft pulley bolt if you’re inquisitive about how to remove crankshaft pulley bolts without an impact pistol. To accomplish this, attach the socket to the bolt and wedge the ratchet’s end into the ground. Then, make sure the ratchet is positioned so that it can turn the crankshaft pulley bolt counterclockwise when the pulley starts to turn. After that, start the engine by turning the ignition key.
Q: What tool is used to remove the crankshaft pulley?
A half-inch drive impact gun is the appropriate tool for removing a crankshaft pulley. In order to fully attach it, you might also use a torque wrench. As a result, it would be beneficial to adhere to the instructions in the service manual when removing a crankshaft pulley and to take the necessary safety measures before raising and supporting the front end of your car. ABC stands for “Always Be Careful,” as the saying goes.
Q: Is a crankshaft pulley bolt reverse thread?
A crankshaft pulley bolt has a typical thread, and turning the bolt counterclockwise loosens it. In order to prevent the bolt from backing out while removing the crankshaft pulley, the engine is turned in the opposite direction from the direction of the bolt’s removal. The water pump and the oil pump may be harmed if the crankshaft is turned incorrectly. Additionally, you might want to learn how to stop the crankshaft pulley from rotating.
Q: How much does it cost to fix a crankshaft pulley?

Using a strap wrench is the most straightforward method of removing a crankshaft pulley without a puller. The safer method is to use a pipe wrench with other tools, such as a breaker or cheater bar.
The crankshaft pulley can be removed without a puller, as this article will demonstrate. This is a much safer and simpler approach. You’ll be able to remove the pulley in no time if you follow these instructions!
Which crank arm’s thread is on the left?
If you’ve ever put together a bike or changed out an old set of pedals, you are aware of something that many people discover far too late: left and right pedals differ from one another. A short glance at the two side by side is all you need to distinguish between them, even without clear clues. Most of the time, they will be marked with a small sticker or engraving indicating right and left. Right pedals adhere to the conventional righty-tighty, lefty-loosey guidelines since they have a right-hand thread. However, left pedals go righty-loosey, lefty-tighty since they have a left-hand thread. The threading on the right pedal will go “up to the right,” and the threading on the left pedal will go “up to the left,” if you hold a pair of pedals side by side with their axles pointing up. Yet why?
