Variable Pin Spanner Wrench
The variable pin spanner wrench utilizes the access holes in pulleys, and other rotational components, in order to maintain them in a stationary position. The variable spanner wrench is adjustable both in circumference size and pin diameter.
The removable hardened steel pins are precision machined to provide a secure fit into their respective access holes and the tool is normally constructed using forged alloy steel. A quality variable pin spanner wrench will be engineered with a slim design so that it can be useful in tighter spaces.
When performing timing belt replacements, especially in front wheel drive vehicles, space can be an issue. With limited distance between the rear camshaft pulley bolt and the strut tower, there is no space for an impact wrench. Loosening the bolt without the benefit of an impact wrench can be challenging.
After safe removal of the timing belt, turning or spinning the pulley is not even an option; in fact, when working with an interference engine you don’t even want to move it. By using a best spanner wrench to hold the pulley in place, you may now utilize a long pattern wrench to loosen the cam pulley bolt.
Honestly, even when access to cam and crank pulleys is possible, with an impact wrench, the pulley should be held securely in place in order to avoid even the slightest mishap. Typically, a good technician will own several different sizes of spanner wrenches, because there are so many different sized pulleys and variations in access hole diameter.
The variable pin spanner wrenche liminates the need for differing spanner wrenches, requiring that you own only one size. By using the adjustable circumference to correspond to pulley size, and the diverse pins which precisely fit access holes, you can safely and securely hold pulleys in place while loosening retaining bolts/nuts.
Variable pin spanner wrenches are available in several configurations. They range from those which are operated using a half-inch drive ratchet, or pull bar, to those with a solid handle for increased leverage and reach. Variable pin spanner wrenches have removable insertion pins, which usually thread into the tool. Pin sizes vary but typically are 3, 3.5, 4, 4.5, 5, 6, 7, and 10 millimeters.
Adjustable Face Spanner Wrench
Adjustable face spanner wrenches feature a fully adjustable circumference range. There are three primary size configurations offered by tool manufacturers. The smallest is adjustable from quarter-inch to two-inch, and made with integrated eighth-inch diameter pins.
The range of the mid-sized adjustable face spanner wrench is from one-inch to four-inch and it has quarter-inch integrated pins. The configuration of the large tool is a three-inch to six-inch wrench with five-sixteenth-inch integrated pins. The integrated pin design and forged steel composition provide strength and durability, and a slim design adds easy access to tight spaces.
Automotive technicians, industrial engineers, and plumbing contractors will find thousands of uses for the adjustable face spanner wrench. It is thin enough to fit into the tightest of spaces, with a long enough handle to be useful in providing added leverage.
No matter whether you are holding camshaft pulleys motionless on a Camry, crankshaft cogs static on a VW, or rendering an oil pump drive sprocket immobile on an Accord, the adjustable face spanner wrench will become your “go-to” tool whenever you simply must hold a pulley in a stationary position. With an unlimited number of adjustment settings within its range, this tool will accommodate virtually any type, size, or pattern of access holes; allowing you to safely and securely hold a pulley while you loosen the bolt or nut.
Leaky oil seals can make a terrible mess of rubber engine mounts and suspension components, but can be particularly harmful to timing belts. Reputable automotive technicians don’t simply throw parts at an engine; they inspect, recommend, and replace components in a responsible manner.
That means removing cam, crank, and auxiliary shaft pulleys and replacing leaking oil seals when performing a timing belt/water pump replacement. Failure to do so will greatly increase the risk of a “come-back” which can cost you time and money. Don’t be intimidated by those over torqued or thread locked cam, crank, or auxiliary shaft pulley retaining bolts/nuts, anymore. Get the adjustable face spanner wrench, and get the confidence that you need to do the job right, the first time.
Adjustable Hook Spanner Wrench
Due to the rugged design and ergonomic engineering of the adjustable hook spanner wrench, one might safely say that anything it will fit around and grip onto, it will loosen. The adjustable hook spanner wrench earned a reputation for durability and reliability on the factory floors of the U.S. and Canada, as well as with the U.S. military.
It is made of forged alloy steel, thin enough to gain access to fasteners in tight places; at thirteen-thirty-seconds-of-an-inch thick and long enough to give you that added measure of leverage when needed. This is the only tool that you need for fasteners with damaged or rounded heads, odd-shaped fasteners, and rusted or corroded fasteners.
Adjustable hook spanner wrenches are available in a variety of sizes which range from an eighth of an inch, and go all of the way to over three-inches. The way that it fits your hand, and “bites” down onto fasteners, gives you a level of comfortable confidence that is unmatched.
No automotive technician’s tool box is complete without a set of these high-quality utensils. The adjustable hook spanner wrench is particularly handy when performing front end, and four-wheel alignments; so much in fact that it can be found on most alignment racks.
After the car, truck, van, or SUV is driven onto the alignment rack, the “heads” of the alignment machine have been attached to the four wheels, and calibrated, actual vehicle specifications are taken and compared to factory specifications. This is done in order to determine what, if any adjustments must be made to the vehicle. In approximately ninety-nine-percent of these instances, a “toe-adjustment” will be recommended.
The position of the vehicle toe directly affects tire wear; nothing will wear the edge off a tire like a misadjusted toe condition. In order to adjust the toe, whether it pertains to front steering components or rear suspension components, the technician must loosen tie-rod lock nuts, and/or tie-rod adjustment sleeves. No other tool accomplishes this as efficiently as the adjustable hook spanner wrench. Either you have one, or you need one.
Shock Spanner Wrench
Anyone who has ever attempted to adjust the shocks on a motorcycle will tell you how hard it can be without the proper tools. Setting shock spring preload on any bike equipped with a swing-arm suspension, as well as soft-tail models, is critical to ride quality, comfort, and safety. Ideally, motorcycle shock adjustments should not be necessary unless a suspension repair, shock, or spring replacement has taken place.
Even in the event that such a repair has been performed, the shock spring preload should be set fairly close to the desired amount (as per manufacturer’s specifications) before shock installation takes place.
The shock spanner wrench is designed for minimal adjustments, only; after the shock is installed. Nevertheless, to make those last minute adjustments with the biological factor (rider) on-board, you will need a shock spanner wrench. If you don’t have it, then shock adjustment is virtually impossible on some models.
There are three basic design choices when considering a shock spanner wrench. Since all of them are fairly economical, a good motorcycle technician might choose to have all three in his/her tool box. The general consensus is that type x will work well on a Yamaha, Kawasaki, Suzuki, or Honda and type y does a better job on a BMW, Ducati, or Triumph, while brand z makes a shock adjustment on a Harley-Davidson, Buell, or Victory a breeze. There is also a matter of personal preference; some technicians claim that a particular design is best, while others choose a totally different design.
The combination design is a straightforward one. It is a single piece design, stamped from a sheet of heat treated alloy-steel, usually finished in either black or chrome. This is a double-ended tool; it actually fits two different sized shock collars, an eighty-seven millimeter on one end and a sixty-eight millimeter collar on the opposite end.
When ordering this type of shock wrench, pay close attention to the tips on the ends of the wrench. If these tips are too rounded they may need to be altered. This can be easily accomplished using a normal bench grinder and “tightening-up” the edges of the points. The wrench will work great on some bikes, yet need to be altered to work on another.
The two remaining types involve the same principle, but only accommodate a single size shock. One is operated using a ratchet and extension. The other is operated using a “T”, or “L” handle, which is included with the tool.
Ball Joint Spanner Wrench
The ball joint spanner wrench home depot is an example of a small tool which is used to accomplish a large and meaningful task. When replacing ball joints on four-wheel drive vehicles which are equipped with a Dana 44 axle, you must adjust the reload on the ball joint’s upon replacement.
The Dana 44 has been used in Chrysler, Ford, GM, International, and Jeep four-wheel drive vehicles performing admirably and garnering a loyal following along the way.
The ball joint spanner tool closely resembles a socket, with four extruding tabs on top, and a hex shape on the opposite end. Typically, a one-inch socket fits the hexagonally shaped end with the tabs fitting snugly into the sleeve which is used to adjust ball joint reload for each front steering knuckle.
Ball joints on this particular type of application should be installed in pairs since the entire knuckle must be removed, in order to replace either the upper or lower ball joint, both should be replaced at the same time. After the steering knuckle is removed, and the new ball joints have been installed, its time to put the ball joint spanner wrench to work.
First, start the new reload sleeve into the steering knuckle, wherever the old one was threaded out. Firmly grasp the steering knuckle with your hands, now, slip it upon the ball joints which you have installed into the axle housing. Start the nut on the upper ball joint, thread it down flush using a wrench or socket and ratchet, and torque it down to manufacturer’s specifications.
Use the ball joint spanner wrench tool to tighten the reload sleeve to manufacturer’s specifications, then thread the lock nut on and torque it, as well. Don’t forget to insert and secure cotter pins, where applicable. Some applications will have the sleeve in the upper ball joint and some will have the sleeve threaded into the axle housing, but the general principle is essentially the same.
Fan Clutch Spanner Wrench
Many late model rear-wheel drive cars and trucks are equipped with a screw-on fan clutch which threads onto a pressed-on water pump pulley. At the base of the clutch fan, flush against the water pump pulley, you will see a large hex-shaped stem. The stem is actually part of the fan clutch spanner wrench and is not serviceable separately.
The water pump pulley is also unserviceable apart from the water pump. By placing a large wrench on the hexagonal stem, and turning (some clockwise and some counter clockwise) the fan clutch, with blades attached, can be unscrewed from the water pump pulley.
Unfortunately, the water pump pulley spins freely and this can be problematic when attempting to unscrew the fan clutch. That is where the fan clutch spanner comes in. Located In the face of the water pump pulley, there are two holes; into these two holes fit two pins, which are on the fan clutch spanner wrench. By holding the water pump pulley with the spanner wrench and using a large, open-end wrench on the fan clutch, it can be unscrewed in order to replace the water pump, fan clutch, or fan blades.
This type of fan clutch spanner wrench requires the use of a second, open-end wrench. On Chevrolet, Ford, and Chrysler pickup trucks, this open end wrench is usually a thirty-six millimeter. Complete fan clutch wrench sets are also sold by many tool manufacturers and are available online.
Another noteworthy option is the fan clutch wrench set which is used in conjunction with a pneumatic air-hammer. These are sold in kit form and typically include a long shaft, which inserts into the air-hammer, and a number of various sized wrench attachments. The wrench attachment is placed on the fan clutch stem.
The long rod is inserted into air-hammer, as well as into the attachment and the trigger is pressed activating the air-hammer. If the serpentine belt remains intact, the sudden force from the air-hammer will usually break the stem free from the pulley on the first attempt. Obviously, this tool is only for use where adequate air pressure can be provided.
Installation of the fan clutch onto the water pump pulley is very straightforward; the most difficult part of the installation is normally starting the threads onto the pulley.
Note: With everything intact, except the fan clutch, put the serpentine belt on to prevent the pulley from turning. Be extremely cautious when removing and installing the fan clutch/blades; allowing it to fall into the radiator can rupture it, causing serious damage.
