Craftsman 319190621 bench grinder Parts

For your Craftsman bench grinder model 319190621, we recommend starting with the model-specific parts list and diagram so you match the exact component (wheel guard, tool rest, switch, cord, or arbor hardware) to your grinder. For broader Craftsman part searches by model number, use Sears PartsDirect.

Steps we use to match the right part

• Confirm the full model number is 319190621 (not just “Craftsman bench grinder”).
• Use the parts diagram to identify the exact section (motor, base, guards, tool rests).
• Match the part by description and location on the diagram, not by appearance alone.
• Compare key fit details before ordering (mounting holes, shaft/arbor size, voltage rating for electrical parts).
• If you are replacing a grinding wheel, verify wheel diameter, thickness, and arbor hole size.

Where to find the model number on a bench grinder

Most bench grinders have the model and serial information on a label:

• On the base or underside of the grinder
• On the rear of the motor housing
• Near the switch box or power cord entry

What you have	What to do next	Why it helps
Exact model number (319190621)	Search by model	Filters to the correct diagrams and compatible parts
Only a partial number	Recheck the label for missing digits	Prevents ordering a similar-looking but wrong-fit part
No label or unreadable	Use grinder features (wheel size, guard style, switch location) to narrow candidates	Helps you identify the closest match before buying

Why it matters

Craftsman bench grinder parts often look interchangeable, but small differences (arbor size, guard mounting, switch style, cord strain relief) can prevent safe installation or proper operation. Matching by model and diagram avoids returns and downtime.

To restore your Craftsman 319190621 bench grinder, we disassemble and clean it, remove rust, inspect the wheels, bearings, and wiring, then reassemble and align everything for a smooth, safe test run. The goal is stable operation with guards and tool rests correctly set.

Safety first

• Unplug the grinder before any work.
• Remove the grinding wheels before opening the housing.
• Wear eye protection and a dust mask when cleaning rust or paint.
• Replace any cracked cord insulation before powering up.

Restoration steps (practical workflow)

• Document and disassemble: Take photos; remove guards, spark shields, tool rests, wheels, and flanges.
• Clean and de-rust: Degrease the base and guards; wire-brush or de-rust hardware; clear cooling vents.
• Inspect rotating parts: Spin the shaft by hand; it should turn freely with no grinding feel or side play.
• Check electricals: Inspect switch, cord, strain relief, and connections; tighten terminals.
• Reassemble and align: Reinstall guards; mount wheels with clean flanges; set tool rest and spark shield clearances.
• Test run safely: Stand to the side on first start; run 1 to 2 minutes; shut off and recheck vibration.

Quick diagnosis guide

Symptom	Common cause	Fix focus
Strong vibration	Wheel not seated, dirty flange faces, out-of-round wheel	Clean faces, re-seat, dress wheel
Motor growl or rough spin	Worn bearings	Replace bearings, verify free rotation
Won’t start or cuts out	Bad switch, damaged cord, loose connection	Inspect and test wiring

Why it matters

A grinder is only “restored” when it runs smoothly and safely. Correct wheel mounting, guard alignment, and solid wiring reduce vibration, prevent wheel damage, and lower shock risk.

A Craftsman bench grinder (including model 319190621) is a stationary power tool with one or two abrasive wheels that we use to sharpen tools, shape metal, remove rust, and smooth rough edges. It mounts to a workbench for stability and controlled grinding.

What it’s used for

• Sharpening chisels, lawn mower blades, and other edged tools
• Deburring cut metal (removing sharp burrs)
• Cleaning up welds and rough stock
• Light shaping of small metal parts
• Polishing with the correct wheel or buffing accessory

Key parts and features you’ll typically see

Even without model-specific documentation for Craftsman 319190621, most bench grinders share these common components:

Feature	What it does	Why you care
Grinding wheel(s)	Removes material by abrasion	Wheel type and grit control speed and finish
Tool rest	Supports the workpiece	Helps keep angles consistent while sharpening
Eye shields / spark guards	Deflects debris and sparks	Reduces risk of eye and face injury
Wheel guards	Covers part of the wheel	Helps contain fragments and directs sparks
On/off switch	Controls power	A sticky switch is a common safety concern

Safe, practical setup tips

• Bolt the grinder securely to a solid bench before use.
• Wear eye protection and keep guards in place.
• Let the wheel reach full speed before grinding.
• Use light pressure; forcing the work overheats metal and loads the wheel.
• Keep the tool rest close to the wheel (a small gap) so parts do not catch.

Why it matters

A bench grinder is fast and effective, but it removes material quickly. Using the right wheel, keeping guards adjusted, and maintaining a steady tool rest helps you get cleaner results and avoid damaging tools or workpieces.
