Replace Flywheel Ring Gear
CAUTION: Oil fumes or oil can ignite above 193C (380F). Use a thermometer and do not
exceed 182C (360F). Do not allow a flame or heating element to be in direct contact with the oil. Heat the oil in a well ventilated area. Plan a safe handling procedure to avoid burns.
1. If ring gear is damaged, place the flywheel on a solid flat surface.

2. Remove ring gear with a brass drift and hammer.
IMPORTANT: If flame heat is used, be sure gear is heated uniformly around circumference. DO NOT OVERHEAT. Overheating may destroy original heat treatment of gear. SEE CAUTION.

IMPORTANT: Whenever rear oil seal is replaced, also replace rear wear sleeve as a matched assembly.
4. Rear oil seal (B) will come off with housing. Use a small punch and hammer to remove oil seal from housing. Discard seal.
IMPORTANT: The preferred method of removing the rear wear sleeve is with JDG790 Rear Wear Sleeve Puller. If removing wear sleeve with a chisel, DO NOT gouge crankshaft flange. Nicks or burrs should be removed with a medium-grit stone. A polishing cloth (180-grit or finer) may also be used when a stone is not available.
5. Remove rear wear sleeve from crankshaft flange.
Crankshaft rear wear sleeve can be removed using one of the following procedures. However, the preferred method is using JDG790 Wear Sleeve Puller Kit.
• Use JDG790 Wear Sleeve Puller to remove wear sleeve from crankshaft flange, as described earlier in this group. See REMOVE CRANKSHAFT REAR OIL SEAL AND WEAR SLEEVE in this group.
• Use the ball side of a ballpeen hammer and tap wear
sleeve across its width in a straight line (to deform and stretch sleeve).
• Score the wear sleeve in several places around O.D.

我们要求各地要使用符合要求的合格的优质轻柴油,并且达到96小时沉
淀,三级过滤,浮子取油,给拖拉机加油时**好使用加油机,以达到进一步分离柴油中水和杂质的目的。
很多地方的油品管理不规范,使用的柴油不是太洁净。拉萨Perkins帕金斯1204E-E44TTAG2约翰迪尔John Deere柴油机活塞、活塞环去哪找,临夏Perkins帕金斯2806A-E18TAG3约翰迪尔John Deere柴油机上下大修包大概的价钱,绵阳Perkins帕金斯2206A-E13TAG3约翰迪尔John Deere柴油机散热器组件联系,朔州Perkins帕金斯1204E-E44TTA约翰迪尔John Deere柴油机水温机油压力转速传感器去哪找,黑龙江Perkins帕金斯1506A-E88TAG5约翰迪尔John Deere柴油机水泵、水泵衬垫电话,大同珀金斯4012约翰迪尔John Deere柴油机大修包去哪找,黄石Perkins帕金斯1106A-70TAG4柴油机去哪买网站,萍乡Perkins帕金斯,2206A-E13TAG6约翰迪尔John Deere柴油机柴油泵、喷射泵组件去哪找,北京Perkins帕金斯4008TAG1A约翰迪尔John Deere柴油机柴油泵、喷射泵组件费用,加油时没有加油机,有的还用小油罐、大桶等把柴油送到地里进行加油,这样就不能充分地过滤出水和沉淀等杂质,所以在使用中要遇到放水、放沉淀的情况,如果报警,7820出现故障码:ECU 000097.00,03,04,16,31等均表示柴油中有水,须要通过滤芯下面的放水开关来排除柴油中的水。
排水时注意的问题,即滤芯下部的开关在放完水之后拧紧时,一定要注意:要对准扣,否则容易拧错扣,会出现从此处往滤芯内倒进气的现象,从而使拖拉机熄火。例:鹤山农场姜秀文的7820。b.更换柴油滤芯之后,排气不干净,拖拉机启动不着。
例:1. 9520T拖拉机不着火
时间:2004年9月18日
地点:内蒙前达拉滨大西江农场的作业点上。
用户反映:滤芯堵塞之后,更换新的滤芯,经过排气之后,约翰迪尔John Deere柴油机不着火,没有故障码出现。
问题分析:由于没有故障码出现,可以确定为油路故障,即燃油内有气没有排放干净。
解决方法:
第一步确认油箱来油顺畅,没有杂质等堵塞油管。
第二步按压手油泵排放系统内的空气,按照OM手册介绍的方法进行排气。确认没有空气了,打开钥匙门启动约翰迪尔John Deere柴油机,不着火。
第三步还是确认系统内有空气,让驾驶员一直按压手油泵,打开钥匙门启动约翰迪尔John Deere柴油机,并且使油门开到**大位置,几秒钟之后约翰迪尔John Deere柴油机启动。
故障原因:由于9000系列的拖拉机是泵喷嘴的,约翰迪尔John Deere柴油机上的油泵是输油泵,只是把油箱内的燃油输送到约翰迪尔John Deere柴油机的供油轨道内,由于轨道内的燃油量不够,故约翰迪尔John Deere柴油机不能启动。
