Escogiendo la relación de transmisión correcta-Video
Existen tres razones principales para reemplazar los engranajes de tu vehÃculo. El primero es para recuperar la capacidad de la conducción y la eficiencia de combustible de un vehÃculo de conducción diaria que ha sido modificado con rines y llantas más grandes. El segundo es afinar las caracterÃsticas de rendimiento de un vehÃculo que es dedicado para todoterreno, donde el enfoque está más en el poder y la aceleración. El tercero es mejorar la eficiencia del combustible. El video adjunto describe el por qué y las consideraciones que deben tenerse en cuenta para encontrar la relación de transmisión correcta para su vehÃculo.
Yukon Drivetrain Installation Kits: The Smart Move
The biggest projects can be derailed by the smallest parts. It’s frustrating to be on a roll with an installation and have the wrenching screech to a halt because you don’t have the right shim, bolt, or other small part. This is where dedicated installation kits save the day. Yukon Gear & Axle has developed the most comprehensive line of differential rebuild and gear installation kits on the market. The strength of these kits is how they’re compiled to deliver the essential small parts needed for different individual drivetrain installation jobs. They range from mini-kits that contain the bare minimum for a gear swap or diff repair to Master Overhaul Kits, that include every component necessary for a complete replacement of bearings, seals, shims, and more. The following kit types are listed with their part number prefix in parenthesis. Yukon Master Overhaul Kits (YK) Yukon Master Overhaul Kits provide all the small parts and components needed to complete any differential job from start to finish. These kits use high-quality Koyo/Timken bearings and races and include carrier bearings and races, pinion bearings and races, a pinion seal, a complete shim kit, ring gear bolts, a pinion nut, a crush sleeve (if applicable), oil baffles and slingers (if applicable), thread locking compound, marking compound with brush, and a gasket. We’ve done all the homework and parts bundling to create a one-click kit that’s easy to order, no wonder Yukon Master Overhaul Kits are so popular among installers and DIYers alike. Yukon Bearing Installation Kits (BK) Yukon Bearing Installation Kits are perfect for shops and builders who have shims on the shelf and are looking to save money versus purchasing a Master Overhaul Kit. Kits include carrier bearings and races, pinion bearings and races, pinion seal, crush sleeve, marking compound and brush. Some kits include differential gaskets as well. Yukon Pinion Installation Kits (PK) Yukon Pinion Installation Kits are designed for ring and pinion gear set installations on lower mileage vehicles where the carrier bearings and races can be reused. These kits include pinion bearings and races, pinion seal, a complete pinion shim kit, and marking compound with brush. Yukon Carrier Installation Kits (CK) Yukon Carrier Installation Kits are a convenient and low-cost solution for carrier changes in situations where one is upgrading to a positraction limited slip differential, a mechanical locker, or an air operated locker. These kits contain carrier bearings and races and a carrier shim kit. Yukon Minimum Installation Kits (MK) Yukon Minimum Installation Kits, or mini-kits, are a low-cost solution for gear changes in newer vehicles where the both the pinion and carrier bearings can be reused. Generally, these kits include a pinion seal, axle seals, crush sleeves, a complete shim kit, marking compound, and a brush. We understand the effort it takes to assemble and setup a differential. Heck, just gathering and arranging the tools can be a monumental task. We also know how maddening it can be getting into a fast cadence only to be derailed by the absence of a seemingly insignificant part. That’s why we created these kits… peace of mind makes the work go all the more smoothly.

Tech Tidbit: All-Wheel-Drive Roll-Out Tire Test
Harmony, balance, and smoothness… are all attributes of a healthy all-wheel-drive system. While there are many component systems that have to work hand in hand, tires are often taken for granted and overlooked by enthusiasts and shop owners alike. A simple roll-out test will ensure your tires are in sync with the driveline. Why A Roll-Out Tire Test? Symptoms of an un-even roll out include, the vehicle pulling to one side, strange locker operation, worn spider gears, worn LSD clutches, and stress on the differential and transfer case. Over time the stress put on transfer case internals can lead to poor performance, and ultimately, failure. Tire Size Looking at an all-wheel-drive vehicle from a four-corner standpoint, with each corner represented by a traction tire, you want to achieve a balance of circumference at each corner. When one corner is moving at a different speed, faster or slower, than the other corners due to a difference in circumference, the resulting imbalance creates stress that will be transferred to the weakest link, which is usually the internal components of the transfer case or the differential. Many customers think replacing a worn tire is a way to fix this issue. Even if it’s the same exact size, tires from different manufacturers have different circumferences… heck even same-sized tires from the same manufacturer but in a different model can have different circumferences. This means problems are still possible. There is a reason why all-wheel drive vehicles, especially Subarus, mandate replacing all the tires at once… it keeps the Symmetrical All Wheel Drive system… symmetrical, happy, and in balance. Buying four tires at a time ensures you’re purchasing from the same production batch and that the tires are well matched. Tire Pressure Tire pressure can also have an impact on the likelihood of trouble. Mis-matched pressures between tires can lead to circumference differences which can result in differences in tire rotation speeds, thus opening the door to uneven drivetrain loads. The Roll-Out Test Step 1: You will need two people, one to view and measure and one person to operate the vehicle. Mark each tire exactly in the 6 o’clock position with a paint stick or chalk. Step 2: Using the front driver’s side tire as the reference tire, have one person drive the vehicle as the other person monitors the driver’s side tire and counts out 10 revolutions. Let it slowly roll forward then stop and creep it forward until the front driver’s side tire mark is once again in the 6 o’clock position. You can mark the pavement at 6 o’clock to serve as a visual reference to better compare each tire. Step 3: Put the transmission in park/neutral. Then check the other three tires and see how the tire marks present. If any of the other marks are not at 6 o’clock, your tires are not revolving at the same speed and there may be undue load being transferred to your transfer case and/or differential. If a mark is off by more than an inch, you may have a bad tire or you’ll need to check your tire pressure… or both. Step 4: If you’ve checked tire pressure and a difference remains in your tires, see your local tire retailer for new tires. As mentioned above, it may be wise to replace all four tires simultaneously with the same/similar date code in order to ensure you’re getting tires from the same manufacturing batch. A properly conducted roll-out test can be a quick and easy way to possibly identify the root cause of a customer’s ongoing issue. You come off as a superhero, the customer is happy, and he or she will be back to support your business in the future. A win-win for sure.
Proper Gear Break-In - Video
Gear break-in consists of controlled heat cycling of the gear set in a way that properly seasons or hardens the gear’s contact surfaces. It is a series of test drives. These critical first few miles of drive time can be the difference between a gear-melting headache and years of carefree driving. Failure to properly break-in your gear set can result in damaged, failing gears and a complete re-do. Read this article in Español Once the wrenches have been laid down and the gears have been properly installed with backlash and preload correctly set there’s still more to do. The gear set must be broken in on urban roads and the freeway because different vehicle speed ranges produce different heat cycling. Towing is a whole other ball game. If you tow you’ll need an additional round of break-in because the physics of towing puts additional pressure on the pinion and slightly changes its position on the ring gear teeth… it’s like you’re hardening a new spot on the gear teeth. Check out the accompanying video for more specifics about proper gear break-in procedures.
