卡特彼勒單體泵齒條同步行程調(diào)整程序

Tools Needed 調(diào)整工具   8T-2684 Rack Synchronization Gauge 齒條同步行程測(cè)量工具

Injector synchronization is the setting of all fuel injector    racks so each injector gives the same amount of fuel to each cylinder. Injector synchronization is done by setting each fuel injector rack to the same position.

         調(diào)整單體泵齒條同步行程是為了讓所有的單體泵提供相同的供油量提供燃油給每個(gè)氣缸. 單體泵齒條同步行程是調(diào)整每個(gè)單體泵齒條行程在相同的位置.

   2.  The top bolt that holds cover (3) in position is synchronization

         pin (2). Remove synchronization pin (2) and plug (1) from the

         front drive housing. Remove the washer from the synchronization pin. Remove the plug and install the synchronization pin into the threaded hole. Tighten the synchronization pin.

         打開(kāi)在前端驅(qū)動(dòng)齒輪殼體左上側(cè)的蓋(3)松開(kāi)同步銷(xiāo)(2)和堵頭(1) 取下同步銷(xiāo)的銅墊片后把同步銷(xiāo)(2)安裝在堵頭(1)的螺孔

    3.  Turn the governor or the actuator terminal shaft to the fuel ON position until the flat face of fuel stop lever (4) contacts synchronization pin (2). This is the synchronizing position or zero reference point. Hold the control linkage in this position when the injectors are adjusted.

        把調(diào)速器或執(zhí)行器終端軸推向油門(mén)“運(yùn)行”的位置至到燃油停止供油操縱桿(4)的平面接觸到同步銷(xiāo)(2). 這就是同步位置或“0”的位置參考點(diǎn). 保持控制杠在這位置當(dāng)進(jìn)行調(diào)整單體泵齒條同步行程.

  4.  Remove the valve covers打開(kāi)氣門(mén)蓋.

  5.   With the fuel stop lever against the synchronization pin, put the 8T-2684 Rack Synchronization Gauge (5) on the round part of the fuel injector rack between the fuel injector body and the end of the rack. Use a screwdriver and make an adjustment of control rod (6). Turn the screw that is located on the control rod one click at a time until the 8T-2684 Rack Synchronization Gauge fits between the fuel injector body and the shoulder at the end of the rack. Remove the screwdriver from the control rod so that no pressure remains on the linkage

    燃油停止供油操縱桿的平面接觸到同步銷(xiāo)后, 把8T-2684 齒條同步測(cè)量工具(5)安裝在單體泵和齒條尾端之間的單體泵齒條圓形部位上. 然后用螺絲起子調(diào)整控制桿(6)內(nèi)的調(diào)整螺絲. 注意同時(shí)細(xì)聽(tīng)調(diào)整螺絲發(fā)出的“滴”聲至到8T-2684 齒條同步測(cè)量工具接適當(dāng)?shù)慕佑|到單體泵和齒條尾端扛之間.把螺絲起子從調(diào)整控制杠取開(kāi), 避免給齒條連桿機(jī)構(gòu)造成壓力

(5) 8T-2684Rack Synchronization Gauge齒條同步測(cè)量工具

(6) Control rod  控制杠 

(7)  Fuel injector rack 單體泵齒條

5.   Check the setting with the rack synchronization gauge. Any pressure on the linkage with the screwdriver will not give a correct indication when the setting is checked with the rack Synchronization gauge. Ensure that the linkage is free and that the linkage is giving an accurate setting by moving the linkage. Check the setting again.Put the box end of a combination wrench over the nut and the bolt.The nut and the bolt connect control rod (6)and the bellcrank. Pull upward on the control rod three times. Check the setting again.

    再檢查8T-2684 齒條同步測(cè)量工具, 當(dāng)再度用齒條同步測(cè)量工具檢查調(diào)整設(shè)置時(shí), 如使用在螺絲起子過(guò)度的力量在齒條連桿機(jī)構(gòu)上將會(huì)造成錯(cuò)誤的設(shè)置.確保齒條連桿機(jī)構(gòu)是松動(dòng)無(wú)阻力當(dāng)移動(dòng)連桿機(jī)構(gòu)時(shí)能給予準(zhǔn)確的設(shè)置. 用扳手套在曲柄桿,  然后把調(diào)整控制桿(6)往上拉3次,再檢查設(shè)置是否準(zhǔn)確.

6.  If the other injectors need to be adjusted, use rack synchronizationgauge (5). When all adjustments have been made, release theactuator terminal shaft.

    接下來(lái)以同樣程序調(diào)整其他單體泵齒條同步行程(5), 調(diào)整完畢把調(diào)速器或執(zhí)行器終端軸松開(kāi).

尋找卡特彼勒活塞在第1缸上止點(diǎn)

Remove cover (1) and plug (3) from the right front side of the flywheel housing打開(kāi)飛輪殼右前端的蓋(1)和堵頭(3) Put timing bolt (2) through the timing hole in the flywheel housing. Use the 9S-9082 Engine Turning Tool (4) and a ratchet wrench to turn the flywheel in the direction of normal engine rotation. Turn the flywheel until the timing bolt engages with the hole in the flywheel.

         把正時(shí)螺絲(2)塞進(jìn)飛輪殼的正時(shí)孔,用9S-9082盤(pán)車(chē)工具(4)和扭力扳手根據(jù)機(jī)組曲軸轉(zhuǎn)動(dòng)方向-逆時(shí)針?lè)较?標(biāo)準(zhǔn)運(yùn)轉(zhuǎn))盤(pán)轉(zhuǎn)至到正時(shí)螺絲(2)剛好能接觸和用手輕輕的扭進(jìn)飛輪螺紋孔內(nèi).

1. Cover 蓋

2. Timing bolt 正時(shí)螺絲

3. Plug  堵頭

4. 9S-9082 Engine Turning Tool盤(pán)車(chē)工具          

3. f the flywheel is turned beyond the point of engagement, the flywheel must be turned in the direction that is opposite of normal engine rotation. Turn the flywheel by approximately 30 degrees. Then turn the flywheel in the direction of normal engine rotation until the timing bolt engages with the threaded hole. This procedure will remove the play from the gears when the No. 1 piston is on the top center.

         如盤(pán)過(guò)活塞在第1缸壓縮行程上止點(diǎn)時(shí), 必須將飛輪往順時(shí)針?lè)较虮P(pán)大概30° 度. 然后再往逆時(shí)針?lè)较?標(biāo)準(zhǔn)運(yùn)轉(zhuǎn))盤(pán)轉(zhuǎn)至到正時(shí)螺絲(2)剛好能接觸和輕輕的扭進(jìn)飛輪螺紋孔內(nèi). 這是為了消除恥輪之間的間隙避免造成不準(zhǔn)確的第1缸的活塞上止點(diǎn).

4.  Remove the valve cover for the No. 1 and No. 11 cylinder head.打開(kāi)第1氣缸和第11缸的氣門(mén)蓋

The inlet and exhaust valves for the No. 1 cylinder are fully closed if the No. 1 piston is on the compression stroke and the rocker arms can be moved by hand. If the rocker arms cannot be moved and the valves are slightly open, the No. 1 piston is on the exhaust stroke. Find the cylinders that need to be checked or adjusted for the stroke position of the crankshaft after the timing bolt has been installed in the flywheel.

         此時(shí)第1氣缸的進(jìn)氣和排氣氣門(mén)是完全閉合. 而用手可以搖動(dòng)進(jìn)氣和排氣氣門(mén)的搖臂.  然后根據(jù)3512氣門(mén)閥調(diào)整順序調(diào)第1缸的氣門(mén). 如果氣門(mén)的搖臂用手無(wú)法.搖移動(dòng)或有點(diǎn)打開(kāi). 那就檢查是否第11氣缸是在壓縮行程的上止點(diǎn). 如果是那就根據(jù)3512氣門(mén)閥調(diào)整順序調(diào)整第11缸的氣門(mén).
