11 7-55 Camshaft Timing Chain < Set timing chain on exhaust camshaft end < Working in cylinder head cavity, remove timing chain cover bolts (arrows). < Remove secondary chain lower guide bolts (arrows). Re- move chain guide. NOTE- Bolt on intake camshaft side is long and extends into timing chain cover. - Remove crankshaft loclting tool from transmission bellhous- ing.
~ ~~ ~ I Camshaft Timing Chain I -- lnstall crankshaft holding tool (BMW special tool 11 8 190/11 8 200). Make sure cut outs in tool engages openings in damper assembly. While counterholding crankshaft with special tool, remove crankshaft center bolt (A). CAUTION- Do not use flywheel locking tool to hold crankshaft stationary NOTE- The crankshaft hub centerbolt is tightened to a torque of 410 Nm (300 ft-lb). 4 Install crankshaft damper puller (BMW special tool 11 8 210) to 11 8 200. and (A) remove damper from crankshaft. The crankshaft must not be allowed to rotate when the timing chains are loosened or removed. The pistons can contact the valves. Use appropriate crankshaft holding tool when loosen- ing crankshaft hub center bolt. Using a drift of less than 5 mm diameter, drive two locating dowels in left and right sides of lower timing cham cover to- ward engine. Remove cover mounting bolts (arrows) and carefully lift cover off. CA UTION- * Use care when removing the cover from the cylinder heao gasket. If the cover is stuck, use a sharp knife to separate it from the headgasket. If cylinder liead gasket Is damaged, remove cylinder head and replace head gasket. See 113 Cylinder head and valvetrain. NOTE- - The chain cover can be removed with the coolant pump in- stalled. Use care when removing the cover from the coolant pipe at rear. - Push primary chain tensioner guide rail aside and remove chain.
... -. rpp- --- Camshaft Timing Chain1 Timing chains, installing (M52 TU and M54 engines) CAUTIOI\C The procedure outlined below assumes that the camshaits are lockedin the TDC installation position with speciallocling tools as shown earliel: - inspect timing chain sprockets. Inspect guide rail and ten- sioner rail for damage. Replace any part that is worn or dam- aged. NOTE- If any sprockets are being replaced due to wear, the chain should also be replaced. 4 Primary timing chain assembly 1. Primary chain tensioner 2. Chain tensioner rail 3. Cranltshaft sprocket 4. Exhaust camshaft sprocket 5. Primary chain 6. Anchor bolt 7. Guide rail 8. Anchor bolt 9. Woodruff key - Install primary timing chain to crankshaft sprocltet and hang upper end from exhaust camshaft. - If necessary, replace crankshaft radial seal in cover. See Crankshaft oil seal, replacing (M52 TU and M54 engines).
(camshaft Timing Chain - To install lower timing case cover: - Clean cover and cylinder block sealing surfaces Use new gaskets and coolant pipe O-ring. Remove timing chain cover dowel pins from engine block. Drive timing cover dowels in until they just protrude slightly from sealing surface. Apply a small bead of silicon sealer (Three Bond 1209 63 or equivalent) to corners of cylinder head where timing cover meets cylinder head and engine block. Tap cover into position until firmly seated. lnstall all bolts hand tight, including two Torx bolts from above. Install secondary chain lower guide. Tighten cover mounting bolts alternately and in stages. Tightening torque Lower timing cover to cylinder bloclc (M6) 10 Nrn (89 in-lb) - Install oil pan with new gasket. See 119 Lubrication Sys- tem. Tightening torque Oil pan to engine bloclc (M6) 8.8 grade 10.9 grade 10 Nrn (89 in-lb) 12 Nm (9 ft-lb) - Align damper assembly with lteyway and tap into place. In- sert new center bolt with washer. CAUTION- Inspect woodruff key for damage before installing hub assembly. - Attach special tools 11 8 20011 1 8 190 to damper assembly. Counterhold damper with 11 8 190 while tightening center bolt. CAUTION- Do not use BMW special tool 1 I 2 300 to hold crankshaft stationary to tighten cranl(shaft hub center bolt. Use only the special tools specified, or equivalent hub holding tool. Have a second person hold special tool 11 8 190 while tightening center crankshaft bolt. Tightening torque Crankshaft hub to crankshaft 410 Nrn (300 ft-lb)
Camshaft Timing chain/ Fit top sprocltet to primary timing chain and install on exhaust camshaft so that pointer (arrow) on sprocltet lines up with cylinder head sealing surface. Position sprocket so that chain slack is on tensioner rail side. 4 Insert BMW special tool 11 4 220 in cylinder head and screw in adjustment screw by hand just until it contacts tensioning rail and chain slack is removed. NOTE- BMW special tool 71 4 220 is an adjustable primary chain tensioner that simulates the function of the tensioner. - Make sure arrow on top primary sprocket is still lined up with upper edge of cylinder head. Reposition sprocket if neces- sary.
11 7-60 Camshaft Timing Chain < Install and tighten down threaded locating studs (arrows) in end of exhaust camshaft. Tightening torque Exhaust camshaft locating stud 20 Nrn (15 ft-lb) 4 Install secondary chain tensioner on cylinder head. - Make sure tensioner is locked in compressed position as described earlier. Fit exhaust camshaft splined sleeve, aligning gap in sleeve splines with corresponding gap on camshaft splines (arrows).
- Camshaft Timing chain] < Slide splined shaft onto exhaust camshaft, aligning larger tooth with corresponding gap of splined sleeve (arrows). Slide splined shaft in further until 3 small or elongated slots in splined sleeve are centered to 3 threaded holes in sprocket. 4 Place intake and exhaust sprocltets in BMW special tool 11 6 180. Position spline gap on intalte sprocket (arrow) as shown and place secondary chain on sprocltets. < Carefully remove chain and sprockets from tool and slide onto camshafts. Align gap in intalte sprocket splines with cor- responding gap in camshaft splines (arrow). CAUTION- Do not alterposltion ofsprocl(ets with respect to chain when removing from specfa1 tool 1 1 6 180. 4 Slide splined shaft onto intake camshaft until approx. 1 mm (0.04 in.) of splines can still be seen.
1 17-62 Camshaft Timing Chain 4 Install intake camshaft spring plate so that FRONT mark is visible. Install mounting nuts (arrows) finger tight. 4 Worlting at exhaust side, insert sprocket mounting Torx screws into threaded lioles (arrows). Initially tighten screws to approx. 5 Nm (44 in-lb), then back off one-half turn. 4 Fit thrust spacer (A) on exhaust camshaft.
Camshaft Timing chain1 4 lnstall spring plate (A) to exhaust camshaft. Make sure that F mark is visible. NOTE- If F mark is no longer visible, install spring plate as shown Install exhaust camshaft impulse wheel, aligning mark (B) with top edge of cylinder head (A). Install mounting nuts (ar- rows) finger tight. 4 Pull out exhaust splined shaft until it stops - Press down on secondary chain tensioner and remove ten- sioner lock-down tool.
~~~ ~ Camshaft Timing Chain - < Preload primary chain: Tighten adjusting screw on BMW special tool 11 4 220 to specified torque. Tightening torque Primary chain tensioner preload 0.7 Nm (6 in-lb) < Preload exhaust camshaft spring plate by pressing on im- pulse wheel while tightening mounting nuts (arrows) finger tight. 4 Install BMW special tool 11 6 150 (VANOS setup bracket) to front of cyl~nder head timing case. Tighten tool mounting nuts (arrows) by hand, then tighten down uniformly until special tool is firmly contacting cylin- der head. CAUTION-- Male sure allgasl(et material is removed from face of cylin- der head. Clean sealing face and keep free of oil.
