(see check valve height in relation to head surface earlier in this group.) valve seat or valve face may be ground to bring within specifications. note: if necessary to resurface cylinder head, a maximum of 0.15 mm (0.006 in.) can be milled from minimum new part dimension. remove only what is necessary to restore flatness. specification cylinder head (rocker arm cavity-to-combustion face)—

remove valve guides 1. position cylinder head with combustion face facing up. 2. drive valve guides from combustion face side of cylinder head using jdg164a driver (a)&a press. 3. inspect valve guide bore for cracking/excessive metal transfer. thoroughly clean valve guide bore. 4. measure valve guide bore in cylinder head. replace cylinder head if valve guide bore is not within specification. specification valve guide bore in head—id 14.94 ± 0.02 mm (0.5882 ± 0.0008 in.) ctm100 (20mar01) 02-020-33 powertech 10.5 l & 12.5 l diesel engines 032001 pn=105 continued on next page cylinder

install valve guides 1. assemble jdg1167 valve guide installation adapter (a)&jdg164a driver (b) onto replacement valve guide (c). 2. position cylinder head resting on combustion face. 3. position valve guide over bore in cylinder head and press guide in head until adapter bottoms on machined surface. 4. measure valve guide installed height. installed height should be as follows: specification valve guide—installed height 14.5—15.5 mm (0.57—0.61 in.) 5. insert a valve stem through valve guide to check for adequate clearance. valve stem should move freely in valve guide. rg,rg34710,86 –19–30sep97–1/1 clean&inspect valve seats 1. use an electric hand drill with copper/brass (soft) wire brush to remove all carbon on valve seats. 2. inspect seats for excessive wear, cracks,/damage. 3. check entire combustion face for rust, scoring, pitting, or cracks. ctm100 (20mar01) 02-020-34 powertech 10.5 l & 12.5 l diesel engines 032001 pn=106 cylinder head&valves 02 020 35 rg,rg34710,87

c—arbor important: valve seat grinding should only be done by experienced personnel familiar with equipment&capable of maintaining required specifications. always keep valve guides&work area clean when grinding valve seats to maintain valve guide bore-to-seat runout. grinding valve seats increases seat width&valve recess in cylinder head. do not grind excessively. only a few seconds are required to recondition the average valve seat. dress grinding stone as necessary to maintain specified seat angle. support the weight of grinder to avoid excessive pressure on the stone. blend/radius all sharp edges 0.50 mm (0.02 in.) maximum corner break to eliminate burrs after grinding valve seats. 1. install appropriate pilot (a) in valve guide bore. 2. install appropriate grinding stone (b) on arbor (c) and position onto valve seat&pilot. 3. using drill from jt05893 heavy-duty seat grinder set, grind valve seats to the following specifications: specification valve seat grinding—contact angle 30° width . 1.50—2.00 mm (0.059—0.079 in.) maximum runout . 0.16 mm (0.006 in.) continued on next page ctm100 (20mar01) 02-020-35 powertech 10.5 l & 12.5 l diesel engines 032001 pn=107 cylinder head&valves 02 020 36 rg,rg34710,87 –19–28nov00–2/2 rg6318 –un–03nov97 measuring valve seat runout a—eccentrimeter 4. use a vernier caliper/scale to measure seat width. if valve seat is too wide, reduce the width with a narrowing stone. note: a narrowing stone will change the top angle of the seat&reduce the outer diameter of the valve seating area. varying the width changes the fine contact between valve face&seat. if seat width is too narrow, valve may burn/erode. 5. if valve does not seat properly, use an eccentrimeter (a) to check valve seat runout. use a new/refaced valve&blueing to check contact between valve seat and face. if necessary, lap the valve onto its seat using a lapping tool&lapping compound. replace valves and inserts as necessary. 6. install new/refaced valve&check valve recess in cylinder head after grinding. (see check valve height in relation to head surface earlier in this group.) rg,rg34710,88 –19–30sep97–1/1 remove valve seat inserts rg8314 –un–06dec97 removing valve seat insert a—jde41296 valve seat puller b—adjusting screw important: be careful not to damage cylinder head when removing valve seats. use jde41296 valve seat puller (a). adjusting screw (b) may need to be retightened during removal of inserts. after removal of inserts, thoroughly clean area around valve seat bore&inspect for damage/cracks. measure bore id. (see measure valve seat bore in cylinder head in this group.) ctm100 (20mar01) 02-020-36 powertech 10.5 l & 12.5 l diesel engines 032001 pn=108 cylinder head&valves 02 020 37 rg,rg34710,89 –19–13aug99–1/1 measure valve seat bore in cylinder head rg8315 –un–21may98 measuring valve seat bore 1. measure valve seat bores in cylinder head and compare with specifications given below. specification intake&exhaust valve seat bore—id 49.424 ± 0.013 mm (1.9458 ± 0.0005 in.) . bore depth . 11.25 mm (0.443 in.) radius at lower bore 0.64 ± 0.25 mm (0.025 ± 0.001 in.) standard intake&exhaust valve seat—od 49.487—49.513 mm (1.9483—1.9493 in.) 2. if valve seat bores are not within specification, oversize seat inserts are available. have a qualified machine shop bore the valve seat to specification for installation of oversize valve seat inserts. (see install valve seat inserts, later in this group.) ctm100 (20mar01) 02-020-37 powertech 10.5 l & 12.5 l diesel engines 032001 pn=109 cylinder head&valves 02 020 38 rg,rg34710,90 –19–03nov99–1/1 install valve seat inserts rg8319 –un–06dec97 valve seat pilot driver rg8318 –un–21may98 installing valve seat insert a—jdg164a pilot driver b—jdg1166 adapter 1. use jdg164a pilot driver (a)&jdg1166 valve seat insert installing adapter (b) to install valve seat inserts in cylinder head. 2. install valves&measure valve recess. (see check valve height in relation to head surface, earlier in this group.) 3. grind valve seats as required to maintain correct valve recess&valve face-to-seat seal. (see grind valve seats earlier in this group.) important: a common practice is to chill valve seat inserts in a freezer before installing. this chilling process allows for less interference when pressing in valve seats. once inserts heat up to room temperature, original press-fit is restored. rg,rg34710,91 –19–13aug99–1/2 install valves rg8306a –un–06dec97 installing valve stem seals a—valve stem seals 1. lubricate valve stems&guides with ar44402 valve stem lubricant/clean engine oil. note: valve must move freely in guide&seat properly with inserts to form an effective seal. 2. insert valves in head (if valves are reused, install in same location from which removed). 3. slide valve stem seals (a) over valve stems&onto intake&exhaust valve guide tower until firmly seated. ctm100 (20mar01) 02-020-38 powertech 10.5 l & 12.5 l diesel engines 032001 pn=110 continued on next page cylinder head&valves 02 020 39 rg,rg34710,91 –19–13aug99–2/2 rg8326 –un–06dec97 installing valve rotators rg8327 –un–06dec97 installing valve retainer locks rg8328 –un–21may98 seating valve retainer locks a—valve springs b—rotators c—retainer locks important: replacement valve springs (r133891) have higher working loads than older springs (r116585). newer valve springs (r133891), have two green paint stripes for identification. valve springs must be replaced in sets of two with new rotators. do not intermix springs across valve bridges. 4. with cylinder resting on combustion face, install valve springs (a)&rotators (b) with retainer locks (c). 5. compress valve springs using jdg982 valve spring compres &install retainer locks on valve stems. 6. strike end of each valve several times with a soft, (non-metallic) hammer to ensure retainer locks are properly seated. 7. recheck valve recess. (see check valve height in relation to head surface, earlier in this group.) ctm100 (20mar01) 02-020-39 powertech 10.5 l & 12.5 l diesel engines 032001 pn=111 cylinder head&valves 02 020 40 rg,rg34710,92 –19–28nov00–1/6 replace unit injector sleeve in cylinder head using jdg981 rg8151 –un–05dec97 removing injector sleeve a—may-25010 punch b—wood block remove unit injector sleeve note: cylinder head must be removed to replace eui sleeve using jdg981 unit injector sleeve installation set. to replace eui sleeve with head installed refer to replace unit injector sleeve in cylinder head using jdg1184 later in this group. important: whenever eui is replaced, sleeve in cylinder head must be replaced also. jdg981-2 swedge is obsolete. disgard this tool&replace with jdg1184-2-1 swedge rod&8132 adapter. 1. remove cylinder head from engine. (see remove cylinder head, earlier in this group.) 2. remove valves from cylinder head.
