  Q: How to properly remove and install the Crankshaft Seal and Harmonic Balancer in V6 engine on Mazda Tribute?

  A:

  In order to remove the component, you have to begin by unplugging the cable at the negative battery terminal. Relax the lug nuts of the right front wheel, elevate the front part of the car and position it firmly over jackstands prior to taking off the wheel. Then remove the splash shield of the fender and the drivebelt. Take off the driveplate access cover and be sure to hold the teeth on the ring gear with a large screwdriver or prybar so that the harmonic balancer does not turn. Next, take out the harmonic balancer retaining bolt. In older models, screw a puller into the holes of the harmonic balancer, whilst in later models, three hooked pullers are used, which attach to the inner hub of the harmonic balancer and not the outer rim. Then take a seal puller and peel the seal off the engine front cover, be sure of the orientation of the sealing lip to the new seal. Installation: To be installed, examine the harmonic balancer seal surface and front cover surface to ensure they are undamaged. Apply clean engine oil on the new seal and put it in the engine front cover with the lips facing inwards. In case there is no seal driver, gently pound the seal with a big socket and a hammer until it is even with the surface of the front cover. Install the TV sealant to the keyway and inside bore of the harmonic balancer, lubricate the outer sealing surface with clean engine oil, center the keyway in the harmonic balancer and the crankshaft key and screw the harmonic balancer with an appropriate installation tool or soft faced mallet and screwing on the retaining bolt to the recommended torque. Install the rest of the parts in the reverse order, snapping the lug nuts of the wheels to the required torque. Rewire the battery, open the engine, and see whether there is oil leaking. The Powertrain Control Module needs to be retrained to an optimum idle and fuel trim strategy to achieve optimum driveability and performance.

  Q: How to remove and install the harmonic balancer for 4 cylinder engine on Mazda Tribute?

  A:

  On 2004 and pre-2.0L engines, start by taking off the drivebelt. When removing the harmonic balancer as an incidental procedure, be sure to place the engine in TDC before loosening the harmonic balancer bolt. The timing pin should not be used to lock the crankshaft because it is not robust and can easily shear off the pin and should be removed before the bolt is slackened or tightened. When unscrewing the bolt, to ensure that the crankshaft does not turn, place a screwdriver in the teeth of the Flywheel, lock it with a chain wrench with protective material or block the flywheel by removing the starter. Undo the screwdriver through the bolts of the harmonic balancer and take it off. To install it, follow the steps in reverse, but be sure that the keyway fits into the locating key of the crankshaft, and screw the bolt until it is tightened to the desired torque, and lock the crankshaft in the same fashion. In the 2.3L and 2.5L engines, the right-front wheel lug nuts should be loosened, the vehicle raised and the right front wheel and fenderwell splash shield removed. Disassemble the auxiliary drivebelt and valve cover, positioning the engine at TDC, and making certain that the camshaft alignment plate and crankshaft alignment bolt are correctly installed. Install a special tool to support the harmonic balancer as you loosen the bolt using an impact gun, making sure to maintain engine at TDC. Take off the harmonic balancer and diamond washer, and get a new one and put it in place of the washer. Apply a bit of clean engine oil to the front seal of the crankshaft, install a diamond washer and harmonic balancer and tighten the new bolt by hand. Install a crankshaft pulley alignment bolt, align the harmonic balancer with the timing chain cover. Do not tighten the harmonic balancer bolt with an impact gun but rather tighten it with the holding tool to the required torque. Take out the holding tool and the alignment bolt, and turn the engine clockwise until it is in TDC. Install the timing pin and crankshaft pulley alignment bolt, making sure that it fits properly: repeat the required steps in case alignment is not possible. Lastly, fit the camshaft alignment tool and verify the position of the camshafts and adjust the engine timing as necessary.
