Because the bolt should not be sticking out of it.. Have it tightened before it comes off and causes damage to crankshaft or soeones windshield. Soon. Good Luck, Ned

How do i fix this problem ? clanking high pitch sound coming from intake.


have a compression test done as it may be a loose valve seat insert
balance shafts are just shafts and unless you have done a bearing for the shaft it will not make a clanking sound as there is no pressure applied to the shaft
basically a balance shaft is like a flywheel that takes vibrations out of the motor

My engine stalls?


The crank sensor is located behind the crank pulley on the 3.8 liter. The crank pulley must first be removed. A 15/16" socket, three very long 8 x 1.0 bolts (pretty sure that is the size, some large washers, and a crank pulley pulley will be required.

With the crank pulley removed mark the bracket where the old crank sensor is located so that the new sensor can be placed in exactly the same position. Failure to do this will result in the new sensor and/or the crank pulley being severely damaged.

Then it's as simple as removing the old sensors and installing the new one.

Good luck and let me know if you have any questions.

How do i fix my mitsubishi fto water pump


Remove the bolt for the crank pulley. Use a gear puller the remove the pulley. If you don't have an impact gun, you have to remove the starter . So you can hold the flywheel/crank shaft from moving as you remove the bolt.

How to replace a timing gear


Remove the bolt in the center of the crank shaft damper pulley

Use a special puller to remove the pulley

Remove the timing cover & use a puller if doing the
crank gear,most likely your doing the top cam gear
because it has plastic teeth or used to have teeth.

May have to remove water pump as well to get cover off

Bottem pulley on engine block is making noise, I think the bearings are going out. What is this pulley attached to and can it be lubricated?


the bottom pulley is the crank pulley. It is attached to the crank shaft. It has two parts, an inner and an outer that are joined together with a rubber isolator. Over time the rubber breaks down and the inner part part of the puller will start to rotate independently from the outer part of the pulley creating a unigue clacking noise.

To solve this you'll need a standard crank pulley puller set. You'll remove the crank bolt and then use the pulley puller to pull the crank pulley off of the crank shaft. The install the new pulley making sure to torque the crank pulley bolt to the proper spec.
