XZ638 and XZ50 series gearbox oil level can be determined from the oil level in the gearbox mounted in the lower right side of the gearbox oil level switch。

XZ668 can be determined from the gearbox oil level in the gearbox mounted in the lower right side of the gauge。

Gearbox oil level inspection procedure is as follows：

1) Before the cold start, you should first check the oil level when cold oil state, the purpose is to check the oil level at cold start-up, there is enough fuel. For quite a long time to stop the use of the loader, the more important。
2) Park the machine on a flat space, speed control lever in neutral position, parking (hand) brake is a brake status, bumper mounted on the frame fixed to prevent machine movement and rotation. Engine idling。
3) XZ638 and XZ50 series gearbox oil level check steps: Before starting the engine, turn on the lower right side of the gearbox oil level switch, oil can switch ports along a small amount of the oil spill, if the oil can not switch from the mouth of a small amount of the oil spill, refueling should switch to oil from the oil port small spills before they start, start the engine and run for about five minutes after the stop, wait for 3 to 5 minutes, check the fluid level again, if the oil level is too high, then by oil plane Switching released on the 6th of excess transmission oil, if the oil can not be a small amount of the oil spill from the switch port, you should add a section on the 6th transmission oil。
4) XZ636-Ⅲ gearbox oil level check steps: Before starting the engine, open the fuel cap, even at the fuel filler cap with a cloth to wipe the oil dipstick, and then there will be the ruler of the oil filler cap into the fuel tube, then remove, if there is more oil in the next mark (about 15mm), you can start, if the next mark following should refuel more to start the next mark. Start the engine run for about five minutes after the stop, to check the oil level through the fuel filler pipe of the oil gauge, oil gauge oil level should be at least 15mm around the next mark. If the oil level in the oil gauge 35mm or more tags, then by loosening four bolts refueling pipe following the release of excess oil on the 6th gear, then lock the fill tube, then refuel the oil gauge is about 15mm over the next mark. If the oil level in the oil gauge mark below, you should add some 6 transmission oil。
5) XZ668 gearbox oil level check steps: Before starting the engine when the liquid level gauge to check the gearbox on the right side should be at the level gauge 2/3 prescription can start the engine in the idling state, liquid position should be in the middle of level gauge), if the oil level gauge in the middle of the following, you should add some oil on the 6th gear; if the oil level gauge in the middle of the above, through the release of excess oil drain 6 transmission oil。

Note：

① Gearbox oil level is high or low, will cause transmission damage, please keep the gearbox oil level in the correct position。
② Check the oil level in the gearbox and replace the gearbox oil in the process, have great attention to cleanliness, can not allow dirt to enter the transmission system in order to avoid transmission damage。

Replace the gearbox oil

On the one hand, as in the transmission fluid torque converter - Transmission hydraulic system working media, on the other hand also for converter - cooling and lubrication of components in the gearbox, gearbox oil grades and therefore should meet the requirements, in accordance with regulations to replace the gearbox oil drain intervals, otherwise it will shorten the transmission using ordered。

Replace the gearbox oil, follow these steps：

1) Start the engine to operate the machines work a few hours, so that dirt, metal Unqualified and sediment suspended in the oil in。
2) Park the machine on a flat space, speed control lever in neutral position, parking (hand) brake is a brake status, bumper mounted on the frame fixed to prevent machine movement and rotation。
3) Turn off the engine, unscrew the bottom side of the gearbox oil drain plug drain carried and used container to catch the。
4) Remove the transmission oil pan and filter, cleaning the inside of the oil pan and clean the filter box attached to the iron and dirt。
5) After cleaning is done and oil, transmission oil pan and filter installed. Join the provisions of the gearbox from the fuel filler on the 6th hydraulic transmission oil, gearbox oil level should be checked the oil level steps prevail。

Note：

①　Since this time the gearbox oil temperature is still high, so to wear protective equipment, and careful to avoid personal injury。
②　Before replacing the gearbox oil should be noted that the parking brake cover, in order to avoid the parking brake friction plates coated with oil, reduce braking performance。
