Park Tool Tips

Posted by Ashley on Sep 28, 2010 | General

BBT-5, BBT-9, BBT-18 and BBT-22 Bottom Bracket Tools

Park Bottom Bracket Tools are used to install and remove bottom bracket cups from the frame. The BBT-22 fits Shimano Octalink and Isis drive 20-tooth, splined bottom bracket cups. The BBT-5 fits Campagnolo 12-tooth, splined bottom bracket cups. The BBT-9 fits 16-notch external bearing bottom bracket cups from Shimano, SRAM, FSA, Campagnolo, Race Face, and others. The BBT-18 fits 8-notch Shimano and Isis drive cups.

Bottom Bracket Removal:
1. Fit bottom bracket tool into non-drive side cup and turn counterclockwise with wrench until removed.
2. Fit bottom bracket tool into drive side cup and turn clockwise with wrench (counterclockwise for Italian threaded cup) until removed.

Bottom Bracket Cup Installation
1. Fit bottom bracket tool into drive side cup and turn counterclockwise with wrench until tight (clockwise for Italian threaded cup).
2. Fit bottom bracket into non-drive side cup and turn clockwise with wrench until tight.

CC-2 Chain Checker

A worn chain shifts poorly and wears sprockets at an accelerated rate. The CC-2 Chain Checker provides a precise measurement of chain wear on most derailleur chains.

1. Set pivoting gauge so '0' is visible in viewing window.
2. Lower the chain checker so fixed pin rests between chain's outer plates and movable pin rests between chain's inner plates.
3. Lightly push pivoting gauge just until it stops. Forcing the gauge will damage the tools pins, resulting in inaccurate measurements. Read number in viewing window. Chain replacement is generally recommended at .75%, although this percentage can vary between chain manufacturers. Contact the manufacturer for specific recommendations.

Because a chain must have a small amount of play in the links to run smoothly, the chain checker will show a reading of .25% to .5% on new chains. This does not mean that the chain is .25% to .5% worn. It only means there is .25% to .5% play built into the links of the chain before it starts to wear.

CCP-22 and CCP-44 Crank Pullers

The CCP-22 removes cranks using a square taper interface.

1. Remove dust cap and crank bolt (or nut) and washer using the proper wrench.
2. Remove nut from handle and puller stud and thread nut into crank arm until it bottoms out. Use wrench if necessary. If nut is not completely threaded into crank arm, the threads will be destroyed when the crank arm is removed.
3. Thread handle and puller stud into nut. When resistance is felt, continue threading handle and puller stud into nut until crank arm is removed.
The CCP-44 is designed to remove cranks using an Octalink or ISIS Drive bottom bracket interface.

1. Remove crank bolt and washer using wrench.
2. Thread nut completely onto handle stud.
3. Insert handle stud into hold of crank until rotating tip contacts bottom bracket spindle.
4. Thread nut into crank and tighten until snug (use a wrench if necessary). Crank threads may be damaged if nut is not completely threaded into crank.
5. Turn handle clockwise until resistance is felt. Continue turning handle until crank is removed.

CCW-5 Crank Bolt Wrench

The CCW-5 is used for tightening and loosening 8mm socket head crank bolts and 14mm hex head crank bolts. It can also be used on pedals that require a 8mm hex wrench for removal and installation.

CM-5 Cyclone Chain Scrubber

The Cyclone Chain Scrubber cleans bicycle chains quickly, easily, and effectively without the hassle and mess of removing the chain from the bike. Regular use improves shifting performance and extends the life of the chain and other drive train parts.

1. Place newspaper or other floor protection under work area. Remove excess mud and grime from chain and other components with a rag. Shift chain to smallest sprocket in the back.
2. Attach chain scrubber around lower section of the chain.
3. Fill chain scrubber with cleaning fluid to fill line. Do not use gasoline, petrol, kerosene or other volatile or flammable solvents.
4. Crank pedals backwards 30 revolutions.
5. Empty chain scrubber and rinse with water. Squeeze fluid from sponge.
6. Repeat steps 2-5.

CN-10 Cable and Housing Cutter

The CN-10 is a shop quality cutter designed specifically for use on bicycle cables and housing. Includes a built-in crimper for both cable end caps and housing ferrules.

CT-3 Chain Tool

The CT-3 quickly and easily removes and installs chains used on derailleur- equipped road and mountain bikes.

The procedures for separating ans assembling derailleur chains vary significantly, depending on the type of connection system used by the chain manufacturer. There are three types. The first type uses a special replacement rivet, which is pressed in with a chain tool each time the chain is separated and assembled. The second type uses reusable rivets, which are partially pressed out with a chain tool to separate the chain, and then pressed back to assemble the chain. The third type uses a special master link to separate and assemble the chain. Separation and assembly of this type of chain does not require a chain tool. The process is preformed by hand or with a Park Tool Master Link Pliers. A chain tool is only used to remove links when shortening the chain length. Below are general instructions for using a chain tool to separate and assemble chains using replacement rivets and reusable rivets.

Chain Separation
1. Place link of chain into primary cradle of tool.
2. Center chain tool pin in chain rivet and turn handle to force rivet out backside of chain.
a. If chain uses a replacement rivet, press old rivet completely out backside of chain.
b. If chain uses a reusable river, do not press old rivet out backside of chain; only press rivet enough to allow chain to be separated.
Chain Assembly
1. Place assembled link of chain into primary cradle of tool. If chain uses a replacement rivet, insert pilot end of replacement rivet into link.
2. Center chain tool pin on chain river and turn handle until rivet is pressed into chain. When properly assembled, and equal amount of rivet should be showing on each side of chain.
3. Remove toold from chain. If chain uses a replacement rivet, remove pilot according to manufacturer's instructions.
4. If tight chain link develops during the assemble process, place link in tight link cradle and turn handle until pin contacts rivet. Turn handle slightly to press on rivet and loosen tight link.

FR-5 Cassette Lockring Tool

A cassette lockring tool is used to remove and install the cassette lockring and cogs on the rear wheel. The FR-5 fits Shimano, SRAM, SunRace, and other 12-tooth cassette lockrings.

Lockring Removal: Fit cassette lockring tool into splines of lockring and install quick release skewer to prevent tool from slipping. Hold cassette cogs with chain whip and turn cassette lockring tool counterclockwise with adjustable wrench until lockring is removed.
Lockring Installation: Fit cassette lockring tool into splines of lockring and turn clockwise with wrench until tight.

GP-2 Pre-Glued Super Patch Kit

The patch kit include six patches and one piece of sandpaper. Works on road or mountain bikes.

Make sure spare tube to be patched is dry. Clean and lightly sand the area to be patched, peel off the protective backing from the patch and apply. Be careful not to touch the adhesive during installation. Press patch firmly onto tube.

GSC-1 GearClean Brush

The GSC-1 is specially designed to remove dirt, grit, and grime from the sprockets on the rear wheel. Just insert the curved end of the brush between the fears and pedal backwards. Then use the brush end to remove the loosened dirt and grit.

PW-5 Pedal Wrench

A pedal wrench is necessary for removing and installing pedals for replacement, service, or packing a bike for shipment.

Pedal Removal:
1. Shift chain to largest chainring. The helps protect hands and arms from sharp chainring teeth.
2. Place pedal wrench on right pedal. Holding left crank for leverage, turn the wrench counterclockwise until pedal is removed.
3. Place pedal wrench on left pedal. Holding right crank for leverage, turn wrench clockwise until pedal is removed.

Pedal Installation:
1. Apply grease to threads of both pedals.
2. Thread right pedal (marked 'R') clockwise into right crank by hand. Tighten with pedal wrench.
3. Thread left pedal (marked 'L') counterclockwise into left crank by hand. Tighten with pedal wrench.

SR-2 Chain Whip

The SR-2 is used when removing cassette cogs from the rear wheel. It firmly holds the cassette cogs so a cassette lockring tool can be used to remove the cassette lockring.

SW-0, SW-1, and SW-2 Professional Spoke Wrenches

A wheel occasionally needs to be straightened or 'trued' in order to keep the rim running straight as it passes between the brake pads. A spoke wrench is required for tightening and loosening spoke nipples when truing a wheel.
SW-0 (Black): .127 (3.23mm)
SW-1 (Green): .130 (3.30mm)
SW-2 (Red): .136 (3.45mm)
Detailed instructions for truing wheels can be found in a number of books, as well as online. Below are instructions for basic lateral truing, which can easily be performed with the wheel in the bike.
1. Place bike in repair stand or lift bike off the ground so wheel can spin freely.
2. Spin wheel slowly and look for side-to-side wobbles as the rim travels between the brake pads.
3. If the rim wobbles to the right, tighten the left side nipples within the area of the wobble 1/4 turn. If the rim wobbles to the left, tighten the ride side nipples within the area of the wobble 1/4 turn. Spin the wheel slowly and note the impact. Repeat as needed to remove the wobble. Note: If further tightening could cause damage to the nipple or create uneven spoke tension, similar results can be obtained by loosening the opposite side nipples 1/4 turn within the area of the wobble. For example, if the rim wobbles to the right, loosen the right side nipples withing the area of the wobble.
4. Repeat procedure on other wobbles until the wheel runs straight through the brake pads.

TB-2 Emergency Tire Boot

The TB-2 Tire Boot quickly and easily installs to patch cuts, scrapes, and tears in any size tire. The thin, reinforced tire boot film adheres to the inside of the tire and prevents the tube from protruding out the cut or tear.

Locate cut or tear then clean and dry surrounding surface to promote adhesion of boot. Peel the protective backing from the boot and apply, allowing it to adequately overlap damaged area. Note: The boot is designed for emergency use. A patched tire should be replaced as soon as possible.

TL-1 Tire Lever Set

Tire levers are used to remove and install a tire and tube from the wheel of a bicycle. TL-1 tire levers are tough enough for the shop and small and light enough for taking on rides for emergency repairs.

Tire and Tube Removal:
1. Deflate tire completely.
2. Insert one lever under bead of tire and hook onto spoke.
3. Insert second lever 4" (8cm) from first and hook onto spoke.
4. Insert third lever 4" (8cm) from second and slide along rim until bead of tire is removed from rim.
5. Removed opposite side bead of tire by hand and pull tire and tube from rim.
Tire and Tube Installation:
1. Inflate tube with just enough air to give it shape and install in tire.
2. Position tire so the valve of the inner tube fits into the valve hold of the rim and points straight to the center hub. A valve that is not pointing straight at the center hub can easily be cut by the rim and cause a flat tire.
3. Work bead of one side of tire completely onto rim with hands; then work bead of second side of tire onto rim. For extremely tight fitting tires, a tire lever can be used to pry the tire onto the rim. Insert tire lever under bead and pry onto rim, using caution to avoid pinching inner tube.
4. Inflate tire to low pressure and inspect to make sure both sides of tire bead are fully engaged on rim. If tire is properly seated, inflate to pressure recommended on tire.

TWS-2 Torx Compatible Star-Shaped Driver Set

The TWS-2 includes the star-shaped wrench sizes currently being used on components such as disc brakes, pedals and chain rings (T7, T9, T10, T15, T20, T25, T27, T30 and T40).
