Craftsman 137186290 miter saw Parts

You can buy replacement parts for your Craftsman miter saw model 137186290 through our Craftsman parts listings and model-based parts diagrams; using the model number helps match the correct components for your exact saw. For part identification and diagrams, use the 137186290 owner's manual.

Best way to buy the right part for model 137186290

• Confirm the full model number on the saw’s data label: 137186290
• Use the parts list and exploded views to identify the exact component name and location
• Match fasteners by size and thread when listed (for example, M5 or M6 hardware)
• Replace worn consumables as needed (for example, blades wear with normal use)
• Keep your saw unpowered while inspecting parts and recording details

What information to gather before ordering

What to collect	Why it matters	Example for this saw
Model number	Ensures correct fit	137186290
Part description	Prevents ordering the wrong item	Guard, switch, motor cover
Hardware size	Helps match screws/washers	M5 x 0.8, M6 x 1.0
Symptom	Narrows likely parts	Won’t start, won’t bevel, excessive vibration

Why it matters

Miter saw parts can look similar across Craftsman models, but small differences in assemblies (like guards, covers, switches, and mounting hardware) affect fit and safety. Using the model-specific parts list reduces returns and gets your saw back to accurate, safe cutting faster.

A Craftsman miter saw like model 137186290 is built around a cutting head (motor and blade), a rotating miter table, and safety and control parts that hold the workpiece steady and let you set accurate miter and bevel angles. For diagrams and names, use the owner's manual.

Main parts you will use most

• Switch handle and On/Off trigger switch: starts and stops the saw; many models also include a safety lock-off button.
• Blade guard: forms a barrier between you and the spinning blade.
• Fence (including sliding fence on some cuts): supports the workpiece and helps prevent movement during cutting.
• Miter handle and miter scale: rotates the table left or right and shows the selected miter angle.
• Positive stop locking lever and miter table lock (quick-cam lock): snaps into common detents and locks the table at the chosen angle.
• Mounting holes: let you secure the saw to a stable bench or stand.

Angle-setting parts (miter and bevel)

The manual describes common positive miter detents at 0°, 15°, 22.5°, 31.6°, and 45° left and right, plus 60° right. If you need an in-between angle, you lock the table at the desired position using the miter table lock.

Sliding fence note for bevel cuts

When making bevel cuts, the sliding fence must be positioned to provide blade clearance. Extending and locking the fence correctly helps prevent the blade from contacting the fence.

Quick reference table

Part	What it does	Why it matters
Fence / sliding fence	Supports and aligns the workpiece	Improves accuracy and helps reduce shifting and binding
Miter scale + detents	Sets common miter angles	Faster setup for trim and framing angles
Guard	Shields you from the blade	Key safety component during every cut
Lock stop latch	Locks saw in lowered position	Safer, more compact storage and transport

Why it matters

Knowing these part names makes it easier to follow setup steps, adjust the saw for a compound cut, and troubleshoot issues like misalignment (heel) or kickback caused by binding or pinching.

On the Craftsman miter saw model 137186290, “unlocking” usually means releasing the cutting head lock and, if equipped, the slide carriage lock so the saw head can rise and the rails can move for cutting.

Unlock the cutting head (down-lock)

Use this when the saw is stuck in the lowered, transport position.

• Unplug the saw.
• Push down slightly on the cutting head to take pressure off the lock.
• Pull the lock stop latch out of the locking hole.
• Let the cutting head rise to the uppermost position under control.
• Keep the lock stop latch for transport and storage only (not for holding the head down while cutting).

For the exact latch location and illustrations, use the owner's manual.

Unlock the slide carriage (rail lock)

Use this when the head will not slide forward and back on the rails.

• Find the slide carriage lock knob on the right side of the slide carriage.
• Loosen the knob to free the slide.
• Tighten the knob again before transporting or storing the saw.

If it still will not move

These checks fix most “old miter saw won’t unlock” complaints.

• Confirm the lock stop latch is fully disengaged from the hole.
• Check for sawdust packed around the pivot, latch, or rail area; clean it out.
• Verify the miter table lock is not clamped so tightly that it is binding movement.
• Inspect for bent hardware or damage from being carried by the handle or arm.
• Add a light dry lubricant to sliding surfaces (avoid oily buildup that traps dust).

Quick reference: what’s locked?

Symptom	Most likely lock	What to do
Head stuck down	Lock stop latch	Push head down slightly, pull latch out
Head will not slide	Slide carriage lock knob	Loosen knob on right side
Table will not rotate	Miter table lock	Lift quick-cam lock, set angle, press down to lock

Why it matters

Unlocking the correct mechanism prevents forcing the handle or arm, which can damage the locking hole, misalign the saw, and create unsafe cutting conditions.

On the Craftsman 137186290 miter saw, the electric blade brake is designed to stop the blade quickly after you release the trigger. When the blade keeps coasting, the most common causes are worn motor brushes, a trigger switch problem, or poor electrical contact in the motor circuit. Use the owner's manual to confirm the operating notes and troubleshooting steps for your saw.

What to check first (safe, quick checks)

• Unplug the saw before any inspection or cleaning.
• Make sure the blade is not rubbing the guard, fence, throat plate, or table (drag can mimic brake issues).
• Blow out or vacuum sawdust around the motor vents and pivot points.
• Inspect the power cord for cuts and confirm the outlet provides steady power.
• Test with no load: run the saw briefly, release the trigger, and observe whether stopping is consistently slow.

Likely causes and what fixes them

Brush wear is a frequent root cause on brushed motors; the manual’s troubleshooting guidance also points to brush replacement as a corrective action for several electrical and control symptoms.

What you notice	Common cause	Typical fix
Blade coasts longer than normal every time	Worn carbon brushes	Replace brushes; retest braking
Brake works sometimes, sometimes not	Trigger switch or loose connection	Inspect switch and wiring; repair/replace as needed
Saw power feels weak and braking is weak	Dirty/worn commutator or motor wear	Brush service and commutator cleaning; motor service if needed

Why it matters

A strong brake reduces coast-down time so you can keep control of the workpiece and work more safely between cuts. If any electrical parts do not work correctly, unplug the saw and correct the problem before using it again.
