What is the oil filter number for a Craftsman YS4500?
For the Craftsman YS4500 lawn tractor, the exact oil filter part number can vary by the specific engine installed on the tractor, so we can’t confirm one single oil filter number from the model identifier alone. The most reliable match comes from identifying the engine brand and model on your tractor, then cross-referencing the correct filter.
Because “YS4500” is a tractor model family label, the oil filter is determined by the engine (commonly Kohler, Briggs & Stratton, or other variants used across production runs).
- Locate the engine ID tag (usually on the blower housing, valve cover, or near the starter)
- Write down the engine model, spec, and serial numbers
- Match the oil filter using the engine’s parts lookup or the tractor’s engine parts diagram
- If your tractor uses a drain tube setup, confirm you have clearance for the filter size
- Replace the filter gasket and lightly oil the gasket before installing
While the oil filter itself isn’t listed in the provided parts set for this YS4500 page, these related oil-service parts can help you complete a clean oil change:
| What you’re checking | Where to find it | Why it matters |
|---|---|---|
| Engine model/spec | Engine ID tag | Determines the correct oil filter thread and gasket size |
| Filter mounting style | At the filter base | Confirms spin-on filter type and clearance |
| Oil drain setup | Drain port area | Helps prevent spills and stripped threads |
Using the wrong oil filter can cause leaks, poor oil flow, or improper sealing. Confirming the engine identification first helps ensure the replacement filter fits correctly and protects the engine during mowing season.

What year is Craftsman YS4500?
We can’t identify an exact model year from the model number YS4500 alone because Craftsman used “YS4500” as a series name across multiple production runs and configurations. For the most accurate year, match the full ID from your tractor’s product label to the correct parts listing for that specific build.
Look for the product label (often under the seat, on the frame near the rear wheels, or under the hood). Then use these details together:
- Model number (you have: YS4500, but this is not unique by year)
- 917.xxxxx number (the more specific identifier that usually narrows the build)
- Serial number (often encodes date information depending on the manufacturer)
- Engine model/type/code (helpful when the tractor label is missing or unreadable)
A common example of a more specific identifier is a 917-series number like 917287220 (as referenced in the page title for this YS4500 parts listing).
“YS4500” typically indicates a Craftsman lawn tractor series, not a single year-specific model. That’s why two YS4500 tractors can use different belts, blades, or electrical parts.
| What you have | What it tells us | What it does not tell us |
|---|---|---|
| YS4500 | Series / family name | Exact year |
| 917-series number | Specific build group | Exact day/month |
| Serial number | Often the best clue | Parts compatibility by itself |
Year matters less than the exact build when you’re ordering parts. For example, deck and drive components can vary between YS4500 versions, so confirming the correct identifier helps you avoid returns and downtime.
If you’re troubleshooting a drive issue while you’re identifying the tractor, checking the condition and routing of the lawn tractor ground drive or blade drive belt, 1/2 x 92-2/5-in 592855201 is a practical first step because belt wear and stretching are common across many YS4500 configurations.

What size belt for a Craftsman YS4500?
On the Craftsman YS4500 lawn tractor, the belt size depends on which system you’re servicing. For this model, we list a 1/2 x 92-2/5-in belt option and a 1/2 x 101-1/6-in belt option; matching the correct belt to the ground drive or blade drive setup is key.
These are the belt sizes we can identify from the model-specific parts available for YS4500:
| Belt listing on this model | Width | Length |
|---|---|---|
| Lawn tractor ground drive or blade drive belt, 1/2 x 92-2/5-in 592855201 | 1/2 in | 92-2/5 in |
| Husqvarna lawn tractor belt, 1/2 x 101-1/6-in 592855001 | 1/2 in | 101-1/6 in |
Because “YS4500” can be built with different deck and drive configurations, we recommend confirming the belt’s location and routing before ordering.
- Ground drive belt: drives the transmission so the tractor moves
- Blade or deck drive belt: turns the mower blades when the PTO is engaged
- Idler pulleys and keepers: maintain tension and belt tracking (often cause belt throw)
Fit issues are often caused by related components or routing, not the belt length.
- Idler pulley is seized or wobbly
- Belt keepers are bent or missing
- Belt routed on the wrong side of a keeper
- Mandrel pulley damage or debris buildup
- Old belt was stretched and used as the measuring reference
Using the correct 1/2-inch width and the correct length for your specific drive or deck setup helps prevent slipping, overheating, and repeated belt failures; it also protects pulleys and mandrel assemblies.
