Cone Wrench and Combination Wrench

Step 1: Wheel Removal

Remove the Wheel
Remove the Nuts or the Skewer

Step 2: Using the vice

Place the Axle Vice in the Bench Vice

Axle parts from left to right: Axle, Cone, Lock Washer, Lock Nut

Clean out the old grease, check for pits.

Put new grease in

Insert new bearings

Replace the dust caps

Place the Axle Vice in the Bench Vice
Find appropriate cone wrenches for both cone and lock nut.
On a rear wheel break lose cone from lock nut on non-drive side. On a front wheel do which ever side.
Remove lock nut any washers or spacers and then cone nut. Keep parts in the order they where removed.
Slide axle out of hub.
Remove dustcaps if they will come out easily if not leave them in.
Remove bearings, magnets work great for this. Save on a clean rag.
Clean cups cones and bearings. This may require the aid of some degreaser if grease is old and hard.

-. Design a direct impact on investment
+== Step 1: Wheel Removal ==
-Decision-making process, including project construction, project design and implementation of the three stages of the project. Control is the key to investment decision-making and design stage, and make investment decisions in the project, its key is design. According to statistics, the same functions to meet the conditions, technical and economic rational design, can reduce the construction cost of 5% to 10% or even up to 10% to 20%, such as a radio factory in the multi-storey frame structure factory (4 layer) designed as an independent unit based on the conventional design, due to the larger multi-plant load, resulting in a larger size independent of the monomer basic, depth deeper (-3.2m), after analysis by other designers such as the use of strip foundation under column can save a lot of concrete, and reduces the depth of excavation to reduce, compared to investing savings of more than 20 million; a two functions, structure, size, form the basis of comprehensive building are similar, including an in consideration of the legislation side effect of many decorative columns set and decorative lines, resulting in the part of the cost difference of 10 million, turns out to be described by a line, investment spending thousands of interference.
