What size line does a Craftsman trimmer take?
For a Craftsman trimmer, the correct line diameter depends on the exact trimmer head and model. For model 316792460, confirm the specified line size in the 316792460 owner's manual before buying line; using the wrong diameter can cause poor feeding, breakage, or extra wear.
Common line sizes you will see (and what they’re for)
Most Craftsman string trimmers are designed around a few common diameters. Heavier line cuts thicker weeds but needs a head and engine designed for it.
- 0.065 in to 0.080 in: light trimming, edging, small grass
- 0.085 in to 0.095 in: general trimming, moderate weeds
- 0.105 in to 0.110 in: heavy weeds, tougher growth (only if the head is rated for it)
Quick compatibility checklist
Before you spool up new line, we recommend checking these items:
- The trimmer head type (bump-feed vs fixed-line vs rapid-reload)
- The maximum line diameter stamped on the head (common on many heads)
- Whether the head uses round, square, or twisted line profiles
- The recommended line length per side (fixed-line heads)
- Any adapter/attachment setup if you’re using a multi-tool powerhead
Typical line size guidance (at a glance)
| Trimming need | Typical line diameter | Notes |
|---|---|---|
| Grass and touch-ups | 0.065–0.080 in | Best feed reliability |
| Mixed grass and weeds | 0.085–0.095 in | Most common “all-around” range |
| Thick weeds | 0.105–0.110 in | Only if head is rated for it |
Why it matters
Line that’s too thick can jam the spool, overload the drive system, and reduce RPM. Line that’s too thin can snap constantly and leave ragged cuts. Matching the diameter to the head rating gives cleaner trimming and longer head life.

Where can I get CRAFTSMAN replacement parts?
For your Craftsman model 316792460, we recommend buying replacement parts from Sears PartsDirect because you can match parts to your exact model and diagram. You can also find Craftsman parts through major retailers and the Craftsman brand store; always confirm fit by model number before ordering.
Best ways to make sure you get the right part
- Match parts using the full model number 316792460 (not just “Craftsman pole saw attachment”).
- Use the exploded views and parts list in the 316792460 owner's manual.
- Replace worn safety and drive components promptly (guard, chain, drive shaft, gearbox).
- Compare the part name and identifier carefully; similar-looking hardware can be different lengths or threads.
- If your attachment is MTD-built (common for many Craftsman outdoor power items), stick with model-matched parts for proper fit.
Common replacement parts customers order for this model
These are examples of parts we commonly see replaced on the Craftsman 316792460 pole saw attachment.
| What you are replacing | What it affects | Example part for this model |
|---|---|---|
| Chain | Cutting performance, safety | Line trimmer pole saw attachment chain 90PX034G |
| Chain guard | Operator protection | Chain guard (model-matched) |
| Gearbox assembly | Power transfer to chain | Gearbox assembly (model-matched) |
| Flexible drive shaft | Drive engagement, vibration | Flexible drive shaft (model-matched) |
Why it matters
Outdoor power equipment parts are highly model-specific. Using the correct Craftsman 316792460 replacement part helps prevent poor cutting, premature wear, and unsafe operation, especially around the bar, chain, and drive components.

What is the average lifespan of 316792460?
A Craftsman 316792460 pole saw attachment typically lasts 8 to 12 years with normal homeowner use and routine maintenance (cleaning, proper chain tension, and bar/chain lubrication). Heavy use, dirty cutting conditions, or running it dry on oil shortens service life.
What most affects lifespan
- Lubrication: keeping the oil system working and the bar/chain oiled
- Chain tension and sharpness: a loose or dull chain overloads the gearbox and drive system
- Debris and sap buildup: increases friction and heat at the bar and sprocket
- Storage: moisture and corrosion damage the bar, chain, and fasteners
- Wear parts replaced on time: chain, guard components, and drive parts
Maintenance checklist (best practices)
- Check chain tension before each use; adjust using the line trimmer pole saw attachment chain tension assembly 753-05597.
- Keep the bar groove and oil port clean; wipe down after cutting.
- Confirm the oil tank is filled and feeding; inspect the line trimmer oil tank assembly 753-05586 if oiling seems inconsistent.
- Replace a stretched, damaged, or dull chain; use the correct line trimmer pole saw attachment chain 90PX034G.
- Inspect the guard and fasteners for cracks or looseness; replace as needed.
Typical wear timeline (homeowner use)
| Item | Typical replacement timing | What you notice |
|---|---|---|
| Chain | 1 to 3 seasons | Slow cutting, smoke, frequent tensioning |
| Bar | 3 to 6 seasons | Crooked cuts, excessive chain play |
| Tensioner/drive components | As needed | Chain won’t stay adjusted, skipping or binding |
Why it matters
Knowing the expected lifespan helps you decide whether to maintain and replace wear parts (chain, tensioner, oiling components) or retire the attachment. Proper tension and lubrication protect the gearbox and drive shaft, which are the most expensive failures.
For model-specific maintenance intervals and adjustment steps, use the 316792460 manual.
