Checking the Timing Belt Model 1MZ-FE

Rice. 2.238. Checking the timing belt

Rice. 2.239. The sequence of installing the timing belt on the elements of the mechanism

Do not bend or twist the timing belt. Do not allow the toothed belt to come into contact with oil or water. Do not stretch the timing belt when installing or removing the camshaft pulley (Fig. 2.239).

Check the timing belt for defects.

Check that the timing belt is correctly installed. Check the timing belt cover gaskets for damage and proper installation. If the belt teeth are damaged or cracked, check to see if the camshaft is jammed. If there is significant wear on the non-working (outer) side of the belt, check for nicks on the tensioner pulley, idler pulley, and water pump drive pulley. If wear or damage is found on only one end of the belt, check the belt guide and correct pulley alignment. If the belt teeth are significantly worn, check the toothed belt cover for damage, the gasket for correct installation and check for foreign matter on the belt teeth. If necessary, replace the timing belt.

Carefully inspect and check the idler pulley and idler pulley. Check for oil leaks from the tensioner pulley seal. If the seal is damaged, replace the idler roller. Check how smoothly the tensioner pulley and intermediate pulley rotate. If necessary, replace the idler pulley and idler pulley. Check tensioner. Check for oil leaks from the tensioner seal. While holding the tensioner with both hands, push firmly on the stem. If the stem does not move, everything is normal. If the stem moves, replace the tensioner.
