Thank you for purchasing the Motion Pro Chain Breaker and Riveting Kit, P/N 08-0467. This kit will break, press on side
plates and rivet hollow-nosed master links on chains from #520 to size #532. For heavy-duty applications or for solid-
nosed riveting please refer to Motion Pro part number 08-0135 Jumbo Chain Tool and part number 08-0142 Quad
Stake Riveting Tool.

• Read all instructions for each procedure before beginning. Improper use of the tool can cause breakage.
•Make sure the tool is clean and apply grease to all threads before assembling and using. This will help the tool
operate more smoothly and allow you to feel tension when using the tool.
•When breaking drive chains larger than #520, grind off the rivet head first to create a flat surface for
placement of the extractor pin tip. The flat surface will help to prevent the extractor pin from becoming misaligned
with the chain pin and contacting the chain side plate, therefore, significantly reducing the load on the tool and helping
to prevent damage to the extractor pin.
•All tightening procedures are to be performed by hand only, using a 14mm wrench. Do not use extensions or
power tools of any kind or the tool may be damaged.

BREAKING CHAINS
Assemble the tool as shown in Image B and the diagram below for breaking chains. Thread the body bolt into the
body. Insert the extractor pin into the spring and drop them into the body bolt with the spring under the pin head.
Thread the extractor bolt into the body bolt above the pin.
Image B shows a drive chain in place.
1. Place the tool over the chain as shown in Image B. The extractor pin must be withdrawn at least 2mm into the
body bolt to clear the end of the chain pin. Do not withdraw the extractor pin too far into the body bolt or it can
get hung up inside the body bolt. One end of the chain pin will be held in position by the end of the body bolt,
while the other end is held in position by the hole in the tool body.
2. Tighten the body bolt securely against the side plate of the chain, but do not over-tighten or the body bolt and
extractor pin could drift out of position. The body bolt is for aligning and supporting the extractor pin, so do not attempt to
break the chain with the body bolt retracted or you will damage the extractor pin.
3.Read this step all the way through before beginning. Tighten the extractor bolt by hand only with a Philips
screwdriver or a 14mm wrench until the chain pin is pushed completely out and through the hole in the tool body. You
will feel some initial tension as the chain pin begins to shear, but afterwards the extractor pin should push smoothly into
the chain link. IMPORTANT: If the chain pin doesn’t start to break free, or you don’t feel the extractor pin going into the
chain link smoothly, back out the body bolt just enough to check that the extractor pin is correctly lined up with the
chain pin. Once the extractor pin and chain pin are aligned properly, tighten the body bolt back down and start over
at the beginning of this step. Do not apply excessive force or use air tools or you may damage the tool.

PRESSING SIDE PLATES
Assemble the tool as shown in Image C for pressing side plates. The body bolt will be threaded into the body, with the
extractor pin, spring and extractor bolt removed. The press plate with the holes will be inserted into the body bolt,
and the press plate with the groove will be placed in the hole in the tool body.

1. Assemble the new chain with the master link, side plate and o-rings (if applicable) as specified by the chain
manufacturer*. Position the assembled master link in the tool as shown in Image D. The side plate with the pins will be
placed against the grooved press plate, and the side plate with the holes will be placed against the press plate with the
holes.
2. Lightly hand-tighten the body bolt until the press plates touch the master link side plates. Check that the master
link chain pins are properly aligned with the groove and holes in the press plates before final tightening.
3. Using a 14mm wrench, tighten the body bolt until the chain pins protrude past the face of the side plate. For clip
type master links, the pins should protrude enough to install the clip into the grooves in the chain pin. For rivet type
master links, the chain pins should protrude enough to be properly flared over the side plate. A simple technique is to
measure the width of the side plates on an adjacent link with a caliper, and then press the master link side plate on until
you achieve the same width dimension.
* Refer to the chain manufacturer’s specifications for distance of chain pin protrusion, and direction and
installation of master link clips. All chains are different, and Motion Pro cannot provide the exact
specifications for your chain.

RIVETING CHAIN PINS
Assemble the tool as shown in Image E for riveting hollow-nosed master link pins. Thread the body bolt into the
body. Insert the rivet tip into the spring and drop them into the body bolt with the spring under the tip head. (Refer
to internal diagram with Image B). Thread the extractor bolt into the body bolt above the tip. Place the anvil in
in the hole in the tool body per Image G.
1. The new master link side plate should already be pressed on(see Pressing Side Plates) so that the chain pin protrudes
past the face of the master link side plate. Refer to the chain manufacturer’s specifications for the proper protrusion
distance. Do not attempt to re-use broken master links, or use a clip on a rivet type master link. Position the tool over
the chain pin to be riveted, with the hollow end of the chain pin facing the rivet tip, and the solid end facing the anvil.
2. Make sure the rivet tip is withdrawn enough to clear the end of the chain pin. Tighten the body bolt securely
against the side plate of the chain, but do not over-tighten.
3. Using a Philips screwdriver or a 14mm wrench, tighten the extractor bolt tightly until the rivet tip spreads the hollow
nose of the chain pin. The end of the chain pin should be flared over the side plate just enough so that the side plate is
solidly held in place. Repeat this procedure on the other chain pin. The amount of flare of a rivet type master link varies
among chain manufacturers. Some specify as little as 0.006” and generally no more than 0.028” (refer to manufacturers
specification to determine proper flare for your chain). This is a very small amount of flare. Do not attempt to flare the
chain pin flush with the side plate, or the chain pin can crack and be weakened, and you risk damaging the tool as well.
Measure the un-flared chain pin with a caliper, and then check the flare often with the caliper to insure you do not over-
flare the chain pin. One turn of the push bolt equals approx. 0.040” of travel, so a typical flare will require less than a full
turn. Image F shows a properly flared hollow-nosed master link.
4. Withdraw the tool from the chain, and visually check that both chain pins show the same size flares. Check that the
riveted-on side plate is in alignment with the side plates of adjacent chain links.
WARNING - It is very important that chain master links be clipped or riveted properly. Improper installation can
lead to great bodily harm or death. If you are unfamiliar or uncomfortable with this process, please have your
work supervised by a qualified technician or bring your vehicle to a qualified facility for repair.
