  Q: How to remove and install the belt tensioner and other engine components on Mazda B2000?

  A:

  In order to take out and install the parts, begin by loosening the alternator mounting bolts, loosening the belt tension, and detaching the alternator belt. The next step is the removal of the attaching bolts to remove the upper front cover and the gasket, and then rotate the engine in the normal direction until the camshaft pulley mark aligns with the V-notch at the top of the front housing, and the crankshaft pulley notch aligns with the arrow on the front housing except in the case of a belt having jumped time. A tool such as the brake pliers or otherwise, can be used to take the tensioning spring away, then the bolt in the tensioner is removed and then take the tensioner. Check the tensioner: It must rotate free and smooth and in case it does not change it. Make sure you keep the belt into the three sprockets and the crankshaft and the camshaft sprockets are timed accordingly. Install the tensioner with the hole of the mounting bolt at the center of the bolt hole, mount the bolt but not tightening. Install the tensioner spring then with the help of a wrench looseness around the crankshaft pulley, rotate the engine in the usual direction, rotating the engine, by a full two turns, until the timing marks are in alignment again, tightening the lockbolt to 28-38 ft.lb. Lastly, replace the cover gasket, place the upper cover, and the alternator belt back in the same order of install removing it and then tighten the bolts to 57 ft.lb.
