Here are some more information for Bearing Gear Puller:
Many factors affect the scope and frequency of aircraft undercarriage overhaul. The possibility of system malfunction increases with severe operating conditions, such as pilot training and agricultural operations.
Cracks are the foremost area of concern, followed closely by worn, sheared, bent, or broken bolts, and elongated boltholes. Although these defects occur during normal aircraft usage, adverse operating conditions accelerate the problem.
Improper adjustment or lubrication can also cause malfunctioning, especially in landing gear retraction mechanisms. Excessive lubrication or the wrong type of lubricant can often be as bad or worse than none at all. With regard to lubrication, closely follow the manufacturer's service and maintenance instructions.
Inspect grease fittings after applying high pressure lubricant to determine that the spring-loaded ball has reseated. Failure of the ball to reseat is an indication of an internal failure of the fitting which can result in serious damage to the part being lubricated.
Bearing removal and replacement should be routine.

The following items are susceptible to service difficulties and should be given attention.
Aircraft Shock Absorbers...Inspect the entire shock-strut for evidence of leaks, cracks, and possible bottoming of the piston, as this condi tion causes overloading of landing gear components and contributes to fatigue cracks. Check all bolts, boltholes, pins, and bushings for condition, lubrication and proper torque values. Grease fitting holes (pressure type) are especially vulnerable to cracks and cross-threading damage. Check all safety wire and other locking devices, especially at the main packing gland nuts.
When assembling shock-struts, use the correct type and number of o-rings, chevron seals, and backup rings. Use only the correct filler valve core assembly, and follow the manufacturer's instructions when servicing with fluid and air. Either too much or too little air or oil will affect aircraft handling characteristics during taxi, takeoff, and landing, and can cause structural overloads.
Shock cords and rubber discs deteriorate with age and exposure. When this type of shock absorber is used, inspect for general condition i.e., cleanliness, stretching, fraying, and broken strands. These components must be kept free of petroleum products as they accelerate deterioration of the rubber.
Nose Gear Assemblies... Attention should be given to the steering mechanism and should include items such as: torque-links (scissors), torque-tubes, control rods and rod-end bearings, shimmy dampers, cables, and turning stops. In addition, check all nose landing gear components, including mud scrapers and slush deflectors, for damage from natural elements.
(a) Towing of some aircraft with the rudder locks installed may cause damage to the nose steering linkage and rudder control sys tem. Exceeding the steering or towing stops should be followed by a close inspection of the entire nose steering assembly. A broken steerng stop will allow turning beyond the design Limit, transmitting excessive loads to struc.tures and to the rudder control system. It is recommended that the nose steering are limits be indicated on the steering collar or fuselage.
(b) Inspect shimmy dampers for leakage around the piston shaft and at fluid line connections, and for abnormal wear or looseness around the pivot points.
Also check for proper rigging, "bottoming" of the piston in the cylinder, and.the condition of the external stops on the steering collar. Bearing removal and replacement should be routine.
Landing Gear Doors... Inspect gear doors frequently for cracks, deformation, proper rigging, and general condition. Gear door hinges are especially susceptible to progressive cracking, which can ultimately result in complete failure, allowing the door to move and cause possible jamming of the gear. This condition could also result in the loss of the door in flight. In addition, check for proper safetying of the hinge pins and for distorted, sheared, loose, or cracked hinge rivets. Inspect the wheelwells for improper location or routing of components and related tubing or wiring which could interfere with the travel of the gear door actuating mechanisms.
Micro-Switches... Inspect micro-switches security of attachment, cleanliness, general condition, and proper operation. Check assoed wiring for chafing, proper routing, and determine that protective covers are installed on wiring terminals, if required. Check condition of the rubber dust boots which protect the micro-switch plungers from dirt and corrosion.

Indispensable Mechanical Tools and Its Uses
Mechanics require a set of tools to work on automobiles. There are different kinds of mechanical tools available to ease the task of working on different types of automobile engines. Most of the necessary tools are made available in packaged kits in various stores but still there are many more tools required by mechanics for smooth and easy repairs of various kinds of automobiles.
Some of the most important types of mechanical tools used by the mechanics are as follows:
* Hand tools: Among the most important tools required by mechanics include the hand tools. Hand tools are of different varieties such as screw drivers, wrenches, utility knives, hammers, pliers, hacksaws, wire stripping tools and wire cutters.
Wrenches are considered one of the handiest tools used by mechanics. It is available in sets and in different sizes. Used mainly for removing bolts and nuts, the wrenches are available in different varieties. However, there are two types of wrenches which are quite essential in every mechanic's tool box. Allen wrenches and the air ratchet wrenches are the two most essential tools though the air ratchet wrench is used for tougher jobs.
Mechanical tools also include pullers of different sizes and varieties such as the slide hammers, ball joint separators, gear puller tools and the bearing pullers. Parts of the automobile which are being removed are protected by using pullers of various types.
Screwdrivers are also included among the essential mechanical tools as there can be a variety of screws of different sizes and shapes to be removed and fixed. Screwdrivers of various lengths are required in addition to Philips and flat head screw drivers. Other types of screwdrivers include the bendable screwdrivers and magnetic tipped screwdrivers.
* Voltmeter: used for checking batteries and identifying its problems. It is also used to monitor the voltage and analyse the problems of electrical components in an automobile.
* Scan tool: one of the most useful mechanical tools used for diagnosing problems in an automobile is a scan tool. It can be connected to an on board computer to analyse the problems.
* Fluorescent drop cords: mechanical tools also include fluorescent drop cords which are very useful. These drop cords are necessary while working underneath a vehicle. Compared to the ordinary bulbs, the drop cords are safer to use as it seldom breaks and never get heated. The drop cords emanate light in large amounts.
The Use of Other Mechanical Tools
In addition to the above mentioned, there are many more useful mechanical tools which are considered essential for a tool kit. Different types of air compressor tools are also used by mechanics to ease their tasks. These compressors can be attached to various gadgets such as drills, spray guns and so forth. Other necessary items include a flashlight, a creeper, a hydraulic jack and funnels.
Mechanics may also require battery tester, charger and a refrigerant leak detector among other tools. All these tools are indispensable to a mechanic and can be bought from many of the online stores listed in the business portals at affordable prices.

Toyota tacoma wheel bearing Replacement ?
I have a 95 toyota tacoma the rear passanger wheel bearing needs Replacement , Ive got conflicting reports on how to go about this , Do i need a special puller? , or will a gear puller work? please help
I don't know exactly for your Tacoma, but for a some other vehicles it's quite simple to replace the wheel bearings, especially on drum brakes.
Simple take the wheel off, adjust the brake shoes down until they are completely free from the drum. Figure out how to remove the drum. Once the drum is off pull the old bearings out and put the new ones in. Put the drum back on and readjust the brakes (that is the hardest part).
Your VERY BEST bet is to go to your local parts store and pick up a Chilton/Haynes repair book for your truck before you start. It will tell you what tools you need.
Your local library might have one you can check out if you don't care to own one, but it's best to own one, FYI.
