Location of crankshaft sensor on 92 Pontiac Trans Sport?
On 1990 through 1995 General Motors 3.8 L engines, the crankshaft positioning sensor was located under the harmonic balancer on the left side of the engine. The harmonic balancer is attached to the main crankshaft and must be removed through an access hole located in the right passenger wheel well. Remove the right front passenger tire after jacking up in stabilizing the vehicle. Inside the wheel well is a small plastic panel that can be removed to access the harmonic balancer mounting bolt. Remove this bolt from harmonic balancer. Using a small wheel puller on the harmonic balancer, gently tap and tighten the wheel puller to remove the harmonic balancer itself. Caution -- be very careful while doing this! The harmonic balancer has a soft aluminum rings attached to it that can easily be bent during the removal process. If they are bent, they will not work properly and will damage the crankshaft positioning sensor! Once the harmonic balancer is removed the crankshaft positioning sensor and wiring is exposed for replacement. Follow the wires leading out of the crankshaft positioning sensor to the electrical wiring coupling. Uncouple this union to disconnect the electrical wires of the crankshaft positioning sensor. Carefully clean the area around the old sensor while still mounted on the vehicle. He is a permanent magic marker and carefully outline for Mark the position of the harmonic balancer before removal. This Is Very Important! If the new crankshaft positioning sensor is not in the precise position as the old one removed, it can cause a no pulse situation to the mission module, which produces the sparkplug timing and firing to the sparkplugs. Crankshaft positioning sensor is held on to the engine by two bolts. Carefully remove these two bolts and the old sensor. Clean the area behind the old sensor with steel wool to make a clean surface for the new sensor mounting. But the new crankshaft positioning sensor in place were the old sensor was removed, follow closely the marks made earlier to position the new sensor at the right location. Mount the new sensor with the two bolts that were removed. Attach the electrical wires from the new sensor following the same path as the old wires on the sensor removed and reattach the electrical coupling to the wiring harness. Carefully replace the harmonic balancer back in place on the crankshaft. Do Not Force the harmonic balancer if you feel any resistance! The circular aluminum fins attached to the harmonic balancer may be pressing against the crankshaft positioning sensor if the crankshaft positioning sensor is not aligned correctly. If you feel any resistance from the harmonic balancer you'll have to climb into the engine area and carefully check to see if the new crankshaft position sensor is in the right location to allow the aluminum fins on the harmonic balancer to fit between slots on the new crankshaft positioning sensor. If the slots do not accept the fins on the harmonic balancer, slightly loosen the two mounting bolts for the sensor and reposition it where you can clearly see that the slots will accept the aluminum fins on the harmonic balancer. Once you have done this, lightly slide the harmonic balancer back into place and check again at the aluminum fins fit cleanly into the slots of the new crankshaft positioning sensor. With the sparkplugs removed, it is possible to rotate the crankshaft and harmonic balancer clockwise to ensure the aluminum fins pass cleanly through the slots of the crankshaft positioning sensor. Once you have verified this, re-tighten but not over tighten, the mounting bolts on the crankshaft positioning sensor. Reinstall the harmonic balancer on the crankshaft and replaced the bolt that holds it to the crankshaft. Be sure to tighten this bolt securely. Again and rotate the crankshaft clockwise by hand very slowly. Listen and feel for any resistance at the harmonic balancer to this turning. If you hear any, remove the balancer and check the crankshaft positioning sensor alignment again. If no resistances felt, the job to be done. Using a cheap spark detection tool, available at most part stores, you can have someone cranked the engine and check for spark plugs. If you have installed the new crankshaft positioning sensor correctly, have it aligned correctly so that the aluminum fins on the harmonic balancer ride smoothly through the slots, you should see spark now at the plugs. This is assuming of course all of the components, the ignition module, the coil packs, and electoral connections are in good working order. When the engine is running and the harmonic balancer rotating on the crankshaft with the aluminum fins sliding through the crankshaft positioning sensor, this provides electrical control pulse to the ignition module, that tells it where the crankshaft position is and regulates when the spark to each plug is released. In this Distributorless design, the crankshaft positioning sensor is a simple Hall Effect switch. While not very complex, it is an integral part of the Distributorless SPARC system for the vehicle and often is suspect to failure. The failure of the crankshaft positioning sensor causes a no spark situation at the plug and the engine just stops running. This can happen at any time. Meaning, you can be driving along, the engine is running fine and then it just suddenly quits! After a short period of time, you can suddenly restart the engine and it runs fine again. This condition generally is caused by the crankshaft positioning sensor overheating and stops producing the needed control pulse to the ignition module which controls the spark at the plugs. Many mechanics misdiagnosis this problem when the vehicle is brought in. 1990 to 1993 onboard computers do not have a trouble code for a bad crankshaft positioning sensor. 1994 and up vehicles have a different onboard computer, called OBT2, and a trouble code for this condition. An intermittent crankshaft positioning sensor can also cause erratic engine operation, from rough idling and power loss, to poor gas mileage. As a general rule, if your vehicle as the 80,000 to 125,000 miles on it, it is a good preventative measure to replace the crankshaft positioning sensor, even if you are experiencing no problems with it. The crankshaft positioning sensor only costs about $35 at most part stores but because of its critical role, it is a part not be ignored in preventative maintenance. I hope this helps some people resolve a serious condition I call The Sudden Stop Syndrome. Otherwise, a 3.8 L V-6 engine has been a fairly reliable engine for General Motors. If you have any questions, be sure your vehicle is serviced by a competent mechanic. C.08 - DERICKUSA1
Removal and installation of a harmonic balancer for a 1993 cutlass ciera?
Remove the large bolt (in center of balancer) then attach a puller by using three(3) bolts of the right size and threads screwed into the holes that are one hundred and tventy degrees(120*)appart that are located toward the periphery(outside) of the balancer and then turn the large center bolt of the puller that is in the depressed area of the crankshaft and the pulley should slide off the crankshaft. The most difficult part of this operation may be in loosening the large center bolt, but that is very easily accomplished by using an impact wrench.

The crankshaft balancer is part of the pulley.
How do you remove a harmonic balancer from a 2005 Mercury Mountaineer?
You must first find a very large telephone pole or concrete building, wrap a large chain around the harmonic balancer and attach it to the building or pole, now be very careful not to start the car at this point as you might damage your vehicle. find another large vehicle preferably a large pick up with at least a class3 hitch. attach this vehicle to your vehicle with a large chain prefereably at least 20 feet long. after attaching everything and making sure all is secure, very carefully and safely accelerate the pull vehicle to 30 miles per hour, the force applied should be suffiecint to remove that stubborn harmonic balancer, if one try does not work repeat. I have never tried this technique but I have been told it works. good luck or you could go see a mechanic if in doubt!
Where is the crankshaft position sensor on a 94 buick lesabre?
Your Crankshaft Position Sensor is located behind your Harmonic Balancer. To replace, remove your serpentine belt from the harmonic balancer. Remove your right wheel and inner fender cover. Obtain a harmonic balancer puller. Most auto parts stores will rent them to you. The puller kit probably won't have the right bolts for your 94 Lesabre. At your local hardware store, buy 3 metric bolts, M6-1.25 x 70mm. If you can get flange bolts it is better, but a fender washer on each bolt will work if you get regular bolts. I learned this the hard way. Before removing the harmonic balancer, you must remove a little inspection plate on the transmission so you can clamp the flex plate in place. There is a special tool for this, but a pair of vise grips will work nicely, just clamp them on the flex plate tightly and be careful not to damage the plate's teeth. Now remove the center bolt on the balancer, attach the puller through the three holes and slowly tighten the center screw till the balancer slides off. Once off, you will see the electrical connection for your crank sensor just to the right of where the balancer was mounted. There is a plastic cover that you must remove. With a bit of gentle prying, it will come off. Now you have access to the two bolts holding the sensor on. While down there, look just above and to the left of where the balancer was and you will see another electrical connector. That is for your cam position sensor. One bolt is all that holds it in, but it has an o-ring so if you need to replace it as well, it will also take a little gentle prying. Reassembly is everything in reverse. Be careful to align the key-way in the balancer with the key on the crank shaft as you reinstall it. Autozone.com has everything you need to know including instructions. That's where I learn. Check there for the torque specs for the balancer bolt. I think it is somewhere around 120 foot pounds.
How do you install a harmonic balancer in a 1977 Lincoln Continental?
take off the old one with a harmonic ballencer puller you can rent one at the tool rental store, there is a large screw holding the ballancer in place with a keyway, you losen the screw tell its almost off but not all the way and then you attach the puller to the ballencer with two screws then you turn the center screw in until the ballancer pops off ..
How do you take a harmonic balancer off of a 1995 Buick Riviera?
Remove the belt(s). Raise the passenger side front tire, support car with jack stand, and remove front tire. Remove the plastic access panel in the wheel opening. You only have to take out the pop-in fasteners on the front half and then bend the panel so that it is out of the way. Using a 24mm socket or wrench, remove the harmonic balancer bolt. It is tight and an impact wrench would be useful here. You will need a universal type balancer puller, such as the ones Snap-On and others sell which have 4 slots. There are 3 oval openings in the face of the balancer. Under these slots are threaded holes to attach the puller screws. The holes are 1/4 inch fine thread (1/4-28 UNF). You will need three 1/4-28 x 3 inch long screws. The screws in my puller kit weren't long enough so I had to get some at a local hardware store. Attach the puller to the balancer being careful not to run the ends of the screws in too far. About 1/4 inch in is OK. Depending on the size of your puller's center bolt, you may have to put some sort of spacer into the opening for the balancer screw to keep from damaging the crankshaft. I used a small deep-well socket. Run the puller's center screw in slowly until it begins to tighten up against the bottom of the hole or puller, whichever is the case. I used an air impact wrench to tighten the puller and remove the balancer. If this is not available, you may have to hold the balancer with a strap wrench to keep it from turning. Just be careful not to damage the underside of the balancer which has the sensor rings attached to it.
How do you time a 1994 jeep wrangler 2.5 4 cylinder?
attach a timing gun to your battery and number one spark plug wire, mark the timing marks on the front harmonic balancer and engine block and use the gun to set the timing to factory specs by loosening and rotating the distributor left or right.
What is the main working cycle of a v8 engine?
it consist of 8 piston in v shape that are attach to the crankshaft and the rest of the process is same compare to the other engine
What is a rod journal?
Connecting rod journals are the part of the crankshaft where the connecting rods attach to. There is one rod journal for each piston/connecting rod in the engine. These journals have a machined surface so the connecting rod bearings can move smoothly as the crankshaft rotates.
You are not a mechanic can you set the timing on your 350 motor?
It's easy. All you need is a timing light. Attach inductive clip to no 1 plug wire, attach batt leads to battery, aim at balancer & pull the trigger. It will flash & Line on balancer in relation to pointer on timing cover will tell you where timing is. To change, just turn distributor & retighten the 1 bolt on manifold. You will probably have between 8-12 degrees initial. Some advance is normal. Do at idle speed so vac/mechanical does not kick in.
How do i set the timing on a 305 Chevy 1992 model?
To do it properly you will need a timing light. Attach it to the number one cylinder spark plug wire and start the engine. Hold the light so you can see the harmonic balancer and check where the timing mark is when the light shines on it. If you need to adjust it you will have to loosen the distributor hold down bolt about 3/4 of a turn. Rotate the distributor very gently until the mark lines up with about six degrees advanced and your 305 should run fine. remember to tighten the distributor bolt back down.
