How to Use Chain Tool Motorcycle Chains Safely

“How to use chain tool motorcycle” does not describe one procedure that works for every chain. A kit may contain attachments for breaking a chain, pressing a side plate, and riveting, but removing an old chain, shortening a new one, and opening a removable connecting link involve different parts and leave different links in place. Identify the job before turning the tool.

A visible clip does not necessarily mean the outer plate will come off freely. If no clip is visible, the chain may have a riveted connection or may be endless. Do not choose an arbitrary pin to push out. The chain’s full model, size, seal design, connecting-link type, and the vehicle and tool instructions together determine which tool and removal method are appropriate.

A Tool That Fits Around the Chain May Still Be Wrong for It

The breaker’s pushing pin must suit the chain size, width, and pin, while the anvil must leave room for the chain pin to exit. Use the pushing pin and anvil specified for that tool together. A “universal motorcycle” label does not establish that the tool can cut every chain or that the kit includes the necessary plate press and riveting tips. The cutting location must follow the tool instructions; some tools explicitly prohibit cutting the connecting link. Identify the connection first, then decide whether to open that connection or push out a working pin as instructed.

Clip links also differ. A slip-fit version is opened by removing its clip and plate according to its design. On a press-fit clip link, the plate may still require a dedicated removal tool after the clip comes off. A riveted connection has no clip to remove first, and an endless chain may have no separate connecting link at all. Treating all of these as the same removal route can put an otherwise aligned tool on the wrong link.

When applying force, the tool’s pushing pin, the target chain pin, and the anvil opening must share an axis. The chain must be firmly supported, with a clear path for the pin to leave. Continuing to turn an off-center tool can break its pushing pin or damage a chain plate. If resistance is abnormal, stop and check the cut location, attachment, and alignment. Do not make up for misalignment with an extension bar, hammer blows, or impact drive prohibited by the tool instructions.

When Shortening a New Chain, Consider the Ends Left Behind

Confirm the new chain’s target by its specified link count; do not simply copy the overall length of a worn old chain pulled straight. Inner and outer links alternate, so the cut determines whether the remaining ends can close with the specified connecting link. Before pushing out a pin, check both the required link count and the end configuration after closure.

The usual approach is to push a pin out of an allowed ordinary outer link, leaving inner-plate ends suited to the connecting link. If the cut leaves the wrong ends, do not hammer the removed working pin back in, weld the chain, or splice in an old section as a quick repair. Pushing out a pin removes the original connection; closing the chain requires a new connecting link specified for the chain’s full model. A matching basic chain size alone does not prove that another link is interchangeable. Nor should a removed connecting link be reused as a load-bearing connection merely because it still looks intact.

Pressing a Plate and Riveting Are Separate Jobs

With a rivet-type connecting link, fit the specified new link first. The plate-press attachment then moves the outer plate in parallel, gradually, to its specified position. Only afterward does the matching riveting tip form the pin ends as required by that model. On a sealed chain, install the matching seals according to the connecting-link instructions. A tool that can break a chain cannot be assumed to close it without the correct pressing and riveting attachments.

Too little or too much plate pressure or riveting can leave the connection unacceptable. Plate position, the finished pin-end dimension, and the point at which it is measured all belong to the full chain model’s requirements. Do not borrow a figure from another chain or substitute feel or visual alignment for measurement. A stiff connecting link, tilted plate, damaged seal, or cracked rivet head is not a finished connection.

After the Tool Comes Off

Support the motorcycle securely, switch off the engine, and prevent movement. Never run the engine to feed the chain through the tool. Follow the tool’s protective-equipment instructions, support the chain section being separated, and keep clear of the chain and sprocket mesh. If the vehicle instructions, matching tool or attachments, specified dimensions, measuring capability, or hands-on experience are missing, stop and have qualified repair personnel handle the work. The same applies when the vehicle requires dealer service.

After connecting the chain, check the side plate, seals, clip or rivet heads, and whether the connecting link bends freely. Closure alone does not mean the motorcycle is ready to ride. Check slack around the full chain, rear-wheel alignment, chain line, and vehicle clearances against the vehicle instructions. Do not ride until any abnormal condition found in these checks has been resolved.
