Toothed Belt, Removing And Installing: Removing
-- Remove the engine support. Refer to ENGINE SUPPORT, REMOVING AND INSTALLING .
-- Remove the lower toothed belt guard. Refer to LOWER TOOTHED BELT GUARD, REMOVING AND INSTALLING .
Risk of destroying by the toothed belt skipping.
- Only turn the crankshaft in the direction of engine rotation.
-- Turn the crankshaft at the crankshaft toothed belt sprocket bolt until the camshaft toothed belt sprocket is at "TDC".
-- Secure the camshaft hub with the :3359 by inserting the pin into the fork on the drive plate -2- and into the hole behind it -1- in the cylinder head.
-- Loosen the crankshaft holder -1- in the camshaft sprocket a half a turn, but do not remove.
-- Secure the crankshaft toothed belt sprocket with the :T10490 .
- The pins on the :T10490 must engage in the threaded holes on the toothed belt sprocket.
- The pin on the :T10490 must engage in the hole on the sealing flange.
The tightening specification for the loosening and tightening of the camshaft central bolts and high pressure pump and should never be transferred to the pin. If a counterholder is used the >>carriers<< may be damaged. Under some conditions, these are not visible and engine damage may be the result. For loosening and tightening the central bolts, remove the pin and then if necessary remove.
-- Pull the pin and loosen the camshaft bolt. Before completely loosening, replace the pin.
-- Loosen the bolt -arrow- for the camshaft toothed belt sprocket.
-- To do so, use the :T10172A with the :T10172/11 .
-- Pull the pin and loosen the camshaft bolt. Before completely loosening, replace the pin.
-- Secure the hub on the high pressure pump with the :T10492 .
-- To do so, place the locking pin in the hub fork -2- and the rear hole -1- in the sub-assembly bracket.
-- Pull the pin and loosen the high pressure pump toothed belt sprocket nut. Before completely loosening, replace the pin.
-- Loosen the nut -arrow- for the high pressure pump toothed belt sprocket approximately 90°.
-- Use the :T10051 to do so.
-- Loosen the nut -1- for the tensioning roller.
-- Turn the tensioning roller eccentric pulley counter-clockwise using the :T10264 in direction of -arrow- until the tensioning roller can be locked with the :T10265 .
-- Turn the tensioning roller eccentric pulley with the :T10264 clockwise in direction of -arrow- until it stops.
-- Tighten the nut -1- by hand.
There is a risk of destroying a used toothed belt if the running direction is reversed.
- Before removing the toothed belt, mark the running direction with chalk or a felt-tip pen for installation later.
-- Remove the toothed belt first from the coolant pump and then from the remaining toothed belt gears.
