Withdrawal
Remove poly V-belt. Remove toothed belt: Toothed belt drive with hydraulically damped tensioning roller, toothed belt drive with friction damped tensioning roller. Remove oil pan. Remove seal. flange on the pulley side. Remove bolts -arrows-. Unlock the 5 fixing brackets and remove the oil separator.
Press in chain tensioner and secure with locking pin -T10060 A- -arrow-. Unscrew intermediate sprocket -1- from crankshaft frame. Loosen bolt -2- and remove chain tensioner. Remove the chain from the sprockets and lay it on a clean bed.
3lock the balancing shaft with a wrench SW 24/27 -pos. 1- as shown in the picture. The wrench must be centered on the balance shaft counterweight and perpendicular to the balance shaft. Loosen counterweight bolt -2- using wrench -T10061-. Only loosen the bolts, do not turn away.
Unscrew crankshaft carrier -3- from cylinder block and remove with balancer shaft. Lay the crankshaft frame on a clean bedding. Loosen the counterweight bolt and remove the counterweight and sprocket. Rotate the balance shaft so that it can be removed from the support.
Installation
Install in reverse order, but the seal must be replaced. O-ring. Replace the bolts, which are further tightened to the appropriate angle. Lubricate the working surfaces of the support with oil and insert the balance shaft. Install the sprocket and counterweight on the balance shaft. The sprocket and counterweight can only be installed in one position. Tighten the counterweight and sprocket bolts by hand. Before installing the crankshaft frame, check the installation of centering sleeves in the cylinder block and the installation of seals in the crankshaft frame. rings. Screw crankshaft carrier -3- onto cylinder block by hand and align. The crankshaft frame must be flush with the outer edge of the cylinder block on the side of the belt pulley. Screw the crankshaft frame crosswise in several steps. Block the balancing shaft with a wrench SW 24/27 -pos. 1- as shown in the picture. The wrench must be centered on the balance shaft counterweight and perpendicular to the balance shaft. Screw counterweight with new bolt -2-. Install the chain tensioner. Clean the chain with a rag. Check that the marking -arrow- is on top of the crankshaft sprocket.
Install the chain on the sprockets of the crankshaft, oil pump and balance shaft. The markings on the sprockets of the crankshaft and balancer shaft must match the chain links marked with a colored felt-tip pen -arrows-.
Instruction. The chain links marked with a colored felt-tip pen must be additionally marked with a zigovka.
Insert the intermediate sprocket into the chain and screw it to the crankshaft frame. Pull the retainer out of the chain tensioner.
Check that the markings on the sprockets on the crankshaft and balancer shaft match the chain links marked with a colored felt-tip pen -arrows-. Install seal. flange on the pulley side. Install oil separator with new seal. ring, to do this: lubricate the seal with oil. ring, lubricate the inner oil separator rod with oil, check the correct installation of the seal. tape, make sure that the oil separator snaps into the crankshaft frame. Install oil pan. Install toothed belt (adjust valve timing): Toothed belt drive with hydraulically damped tensioning roller, Toothed belt drive with friction damped tensioning roller. Install poly V-belt.
