1) Remove the injection drive tensioner, then the gearwheel and the guide plates, which should allow the
removal of the belt and the gear on the crankshaft. Dayco BIO kit KBIO01 provides all the components
– crankshaft and injection pump gearwheels, belt guides and belt – in a single replacement ‘cartridge’; for
which the belt guide bolts should be tensioned to 23 Nm and the gearwheel bolt to 50 Nm. Once installed, fit a new Dayco hydraulic tensioner ATB2635 and tension to 65 Nm.
2) Refit the cover, followed by the auxiliary belt idler, which should be tensioned to 48 Nm. Replace the
existing crankshaft oil seal with a new seal and refit the crankshaft pulley, using a new bolt, which needs to
be tightened to 100 Nm. Refit the injection pump pulley and tension the bolts to 24 Nm and replace the rest
of the items, including all the timing drive components contained in Dayco Timing Belt Kit KTB470 & KTB251.
