This document provides instructions for disassembling and assembling the transmission hydraulic control valve of a Caterpillar 637G wheel scraper. The disassembly procedure involves removing 19 parts in 19 steps, taking care with springs. The assembly procedure reverses this in 19 steps, also noting springs and proper torque values. Installation involves positioning valves and manifolds before refilling transmission oil.
In this presentation, we have discussed a very important feature of BMW X5 cars… the Comfort Access. Things that can significantly limit its functionality. And things that you can try to restore the functionality of such a convenient feature of your vehicle.
