been running, engine and fuel filter housing may be hot. 1. close fuel shut-off valve (if equipped). 2. clean entire area surrounding fuel filter assembly to keep debris from entering fuel system. 3. remove cap from fuel filter housing. if cap is too tight, a wrench/pliers may be used to loosen cap, as shown. dpsg,ouo1004,1015 –19–24aug99–2/5 rg10303 –un–02sep99 relieve vacuum 4. relieve vacuum in filter housing by operating hand primer until fuel filter “pops up”. if filter does not “pop up” after about 30 strokes of primer, a small screwdriver may be used, as shown, to carefully pry under filter flange to relieve vacuum in the housing. continued on next page ctm188 (20mar01) 02-091-4 powertech 10.5 l & 12.5 l level 6 fuel system 032001 pn=58 single rail fuel system repair&adjustment 02

suspended straight up in top of housing to drain fuel from filter. 6. allow fuel to drain completely from filter into housing. carefully begin rotating filter from housing, as shown, until completely upside down to ensure minimal leakage from fuel filter. 7. place filter in container suitable for diesel fuel. important: reusing fuel filter once removed from housing may result in trapped air in the filter, causing fuel to overflow from the filter housing during insertion of filter element and/or cause the engine to stall and not restart without additional system purging. continued on next page

(b)&max (a) fuel levels indicated on the outside of the housing&on the corresponding marks on the center tube. if the fuel is below the min level, carefully open the fuel supply shut-off valve a small amount (if equipped) to add fuel. operate the hand primer to add more fuel if required or if the unit is not equipped with a fuel supply shut-off valve. important: fuel level below the min indication may result in trapped air in the filter causing the engine to stall? restart without additional system purging. fuel level above the max indication may cause fuel to overflow from the filter housing during insertion of filter element. always use a new filter element whenever an existing element has been removed from filter housing. 2. insert new (dry) fuel filter into filter housing. 3. reinstall fuel filter cap&tighten by hand to the following specification. specification fuel filter cap/cover-to-housing—torque. 11 n?m (100 lb-in.) 4. open the fuel supply shut-off valve (if equipped). 5.

found by viewing camshaft timing lobe through camshaft timing pin bore while rotating engine. the double timing slot (e) will be at approximately 11 o’clock (viewed from rear of engine) when pin is installed in slot (d).this ensures that engine is locked at tdc of no. 1 cylinder’s compression stroke. intake&exhaust rocker arms on no. 1 cylinder should be loose. 3. remove threaded plug from
