Frequently Asked Questions
No. 5PK748200 is listed as a Shim Package Refill for an existing Hot Cams valve shim kit. It is intended to replenish commonly used shim sizes, not replace a full kit. Confirm which base kit it matches before purchasing.
Based on the Hot Cams part numbering convention (748 in the number), it is very likely a 7.48 mm shim refill pack. Always verify against your OEM spec and the Hot Cams catalog or distributor listing to be certain.
Fitment depends entirely on the shim diameter your engine uses. Check your service manual or an OEM fiche for the valve shim diameter; if it uses the same diameter as this Hot Cams refill pack, it will be compatible. There is no single make/model list because 7.48 mm shims are shared across many engines.
Yes, as long as the shim diameter and thickness range match what your engine requires. Hot Cams shims are hardened steel and work fine alongside OEM or other aftermarket shims if the dimensions are correct.
You don’t need special tools beyond normal valve adjustment tools: feeler gauges, basic hand tools, and a torque wrench. Some engines also require a cam chain tensioner tool or a valve bucket depressor, as specified in the OEM manual.
Installation Guide
Difficulty
Medium
Est. Time
1 hr 0 min
Tools Required
- Service manual for the specific motorcycle/ATV/UTV
- Metric socket set
- Torque wrench (inch‑lb or Nm, per OEM spec)
- Feeler gauge set (metric)
- Magnetic pickup tool or small magnet
- Pick or small flat screwdriver (for shim removal on some designs)
- Caliper or micrometer (to verify shim thickness if needed)
- Clean shop towels and parts tray
Pro Tips
- Verify your OEM shim diameter in the service manual before buying any shim refill pack.
- Measure and record all clearances and existing shim sizes in a table before changing anything.
- Work on one cylinder or one cam pair at a time and label every shim location.
- Aim for the middle of the OEM clearance range so you have room for future wear.
- Lightly oil new shims and cam lobes during reassembly and always rotate the engine by hand two full revolutions to re‑check clearances before starting.
Common Mistakes to Avoid
- Ordering the wrong shim diameter (e.g., 7.48 mm vs 9.48 mm)
- Mixing up shim locations and not recording original measurements
- Rotating engine in the wrong direction or using the starter with cams loose
- Not torquing cam caps to factory spec and sequence
- Setting clearances at the extreme tight side of the spec, leaving no margin
Comparison vs Stock/OEM
Functionally equivalent to OEM valve shims when the correct diameter and thickness are used. Intended as a cost‑effective way to maintain proper valve clearances without purchasing individual OEM shims.
Improvements
- Lower cost per shim compared to many OEM dealers
- Convenient assortment and refill packaging for shops and frequent tuners
- Allows quick fine‑tuning of valve clearances without waiting on OEM special orders
Considerations
- Always match shim diameter and thickness to OEM spec
- Mixing different brands is acceptable as long as hardness and size are correct, but keep accurate records of what is installed where
Durability & Warranty
Expected Lifespan
Under normal conditions, hardened steel valve shims typically last the life of the engine and are only changed to correct clearance, not because they wear out quickly.
Warranty
Standard aftermarket parts warranty from distributor or retailer (exact terms vary by seller; usually limited warranty against manufacturing defects).
Maintenance
Follow the valve clearance inspection interval in the OEM service manual; re‑measure and change shims only when clearances move out of specification.
