The injection timing device is attached to the inter\u00admediate sprocket shaft (104) by a hex-head bolt (95).<\/div>\n
Vacuum pump lubrication is provided via the inter\u00admediate sprocket shaft (104) and the hollow hex-head bolt (95). The adjustment range of the injection timing device amounts to 8\u00b0 up to model year 1979, starting model year 1980 7.5\u00b0.<\/div>\n<\/div>\n<\/td>\n

Leave chain on sprocket and deposit together in chain box. 11 Unscrew chain drive retaining screw (94) and withdraw upper pin of guide rail (93) using puller. 53 Camshaft sprocket 89 Guide rail 93\u00a0 \u00a0 Guide rail 93a Guide rail 94\u00a0 \u00a0 Retaining screw   12\u00a0 \u00a0 \u00a0 Lift chain out of injection timing device, sliding support plate between injection timing device and chain for this purpose. For better fixing, intro\u00adduce guide pin (arrow) into tapped hole. 13\u00a0 \u00a0 \u00a0 Remove or push off injection timing device. Attention: After removing injection timing device, be sure not to turn crankshaft or camshaft. 14 Remove injection timing device bush (2) and thrust ring (3) from intermediate sprocket shaft. 1\u00a0 \u00a0 Injection timing device 2\u00a0 \u00a0Bush 3\u00a0 \u00a0Thrust ring 4\u00a0 \u00a0 Intermediate sprocket shaft 5\u00a0 \u00a0Woodruff keys   07.1.8-240\/3 F3       15 Check guide rails (93 and 93a) (sight-check), exchanging if necessary.   Installation 16\u00a0 \u00a0 \u00a0Oil thrust ring (3) and bush (2), slipping onto intermediate sprocket shaft. Make sure that both Woodruff keys (5) are correctly seated (illustration. No. 14). Note: If injection timing device needs exchanging, position the old one on the new one in such a way that the keyways of the one agree with those of the other. The paint mark on the old injection timing device must now be transferred to the new one. 17\u00a0 \u00a0 \u00a0Slip injection timing device onto intermediate sprocket shaft. 93 Guide rail 93a Guide rail   18 Draw chain upward and lift camshaft sprocket with chain, making sure that mark on injection timing device agrees with that on crankcase. If necessary, turn injection timing device until the two marks agree again. Then withdraw supporting plate. If marks are offset, insert supporting plate again and relocate chain on sprocket to make marks agree.   19 Slip camshaft sprocket and chain onto cam\u00adshaft, making sure that mark in shim agrees with mark in first camshaft bearing.   07.1.8-240\/4 F3       Check once again whether all marks are aligned in same way as before removal and whether TDC position of balance disk is correct.     20\u00a0 \u00a0 \u00a0 Install chain tensioner (05-310). 21\u00a0 \u00a0 \u00a0 \u00a0Introduce bearing pin of guide rail (93a) into crankcase, coating pin end with sealant. While driving into position, make sure that wire retainer of guide rail engages notch in bearing pin. 22\u00a0 \u00a0 \u00a0 Insert and tighten retaining screw (94) with new sealing ring. 23\u00a0 \u00a0 \u00a0 Check start of delivery adjusting if necessary (07.1-110and 115). 24\u00a0 \u00a0 \u00a0 Vent injection system (07.1-140).   07.1.8-240\/5       25 Fit hollow hex-head bolt and torque to 40 Nm. Attention: Be sure to use hollow hex-head bolt only.   26 Check end play of intermediate sprocket shaft Specified value is 0.05\u20140.12 mm. Withdraw thrust ring (3) if necessary.   27\u00a0 \u00a0 \u00a0 \u00a0Insert camshaft sprocket bolt and torque to 80 Nm. 28\u00a0 \u00a0 \u00a0 Check injection timing device for satisfactory operation, using a wrench to turn hexagon screw clock\u00adwise to stop. When screw is released, injection timing device must return to old position. 29\u00a0 \u00a0 \u00a0 Fit vacuum pump with new gasket and connect vacuum lines. 30\u00a0 \u00a0 \u00a0 Hold guide rail (89) in position, insert drive pin and tighten. 31\u00a0 \u00a0 \u00a0 Fit cylinder head cover, making sure that rubber gasket is correctly seated. 32\u00a0 \u00a0 \u00a0 \u00a0Attach and check control linkage, adjusting if necessary (30-300). 33\u00a0 \u00a0 \u00a0 Fit radiator and connect all lines. 34\u00a0 \u00a0 \u00a0 Run engine and check for leakage.   07.1.8-240\/6 F2        <\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_crdt_document":"","footnotes":""},"categories":[49,44],"tags":[],"class_list":["post-2943","post","type-post","status-publish","format-standard","hentry","category-injection-system","category-om617"],"aioseo_notices":[],"featured_image_src":null,"author_info":{"display_name":"mackuz","author_link":"https:\/\/mbci.mackuz.ovh\/index.php\/author\/mackuz\/"},"_links":{"self":[{"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/posts\/2943","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/comments?post=2943"}],"version-history":[{"count":1,"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/posts\/2943\/revisions"}],"predecessor-version":[{"id":2944,"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/posts\/2943\/revisions\/2944"}],"wp:attachment":[{"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/media?parent=2943"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/categories?post=2943"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/tags?post=2943"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
