  2. TRANSFER CASE WORK

  3. Transfer Case Work The transfer case is an integral part of the four wheel drive system of a motor vehicle. Its purpose is to turn the vehicle into an all-wheel drive when necessary by allowing the axles of the front and rear to move together. To do this the transfer case forms a part of the drive shaft. This is the part of the vehicle that transmits power to the drive train. Through the drive shaft the transfer case also connects to the transmission (part which sends signal to change to four wheel drive) and the front and rear axles (points where signal for four wheel drive manifest).

  4. Mechanism of Action of the Transfer Case • Bear in mind that the purpose of the transfer case is to achieve four wheel versus two wheel drive. When it receives the signal via the transmission, certain conformational changes take place to ensure that happens. Below is a step by step process of just how the transfer case works to provide four wheel drive.

  5. The transfer case located on the drive shaft receives a signal via the transmission. The signal from the transmission generates from a change in the gear by the driver of the vehicle. In this case the driver would switch to the four wheel drive gear/s options in the vehicle. • The transfer case interprets the message and relays it to the axles; both front and rear. • When both axles operate at the same time the vehicle is in four wheel drive and can withstand off-road conditions such as bad weather and rough terrain.

  7. GEAR BOX

  8. MAINTAINANCE Stork Gears & Services is well known for her short delivery times and quality of her gearbox repair services. Besides gearbox repair, equally important is discovering the root cause of the gearbox failure in order to avoid unplanned machine downtime in the future. To pinpoint equipment failure we perform oil analysis, vibration measurements and thorough visual inspection, for instance examination of abrasive wear patterns and gear tooth pitting. 

  9. CHANGING OIL GEAR BOX • First off, you need to buy 2 gallons of EP90 gear oil (stick to EP90 and not EP80/90, as EP90 is what is recommended for the • keeping pressure on the nut. When the nut is undone, remove it quickly, and hopefully you should avoid getting old EP90 • Then, having placed a suitable container underneath to catch the draining oil, loosen the brass nut and then remove it, • Once the oil has finished draining, replace the drain/sump plug. I usually put a light smear of instant gasket on the last few • Once the gearbox is full, the oil will start to come back out of the filler aperture; now you can replace the filler plug. • Remember, you can check the oil level in the gearbox at any time by removing this plug….just allow time for the oil to settle

  10. CHECKING OIL GEAR BOX Safety check • Do not put your finger into the filler plug opening to check the fluid level whenever the transmission is rotating. • If the vehicle has been driven just prior to checking the fluid level, the fluid could be very hot. When you remove the filler plug, the hot fluid may run out. Be careful not to burn yourself. • Make sure that you understand and observe all legislative and personal safety procedures when carrying out the following tasks. If you are unsure of what these are, ask your lecture.

  11. CHECKING • Raise the vehicle on a hoist and make sure it is level. • Find the filler plug, referring to the shop manual if necessery • Clean the area around the filler plug to keep dirt out of the engine. • Remove the filler plug with the correct wrench to prevent damage to the plug. • If fluid begins to leak slowly, then the reservoir is full. • If fluid runs out freely, let it drain into the drain pan until it seeks its own level, which is just at the bottom of the filler plug opening

  12. If the lubricant level is below the level of the filler plug, bend a short length of metal wire and insert it into • Pull the wire out and note the lubricant level. If the level is down, you will need to add fluid of the correct lubricant type and grade, to bring it up to the recommended level. • Check the plug for damage to the thread, and sealing gasket if it exists. Install a new gasket. Replace the filler plug and tighten it with the correct wrench to the manufacturer’s recommended tension.
