Huthbrother camshaft replacement kit for Briggs & Stratton engines — includes oil seal & crankcase gaskets (fits 793880/84005207)

Huthbrother's camshaft replacement kit (fits part numbers like 84005207 and 793880) is a complete drop-in solution including the camshaft, oil seal, and crankcase gaskets for many Briggs & Stratton small engines and Toro ride-on mowers.

This kit bundles the central rotating camshaft with the matching oil seal and two crankcase gaskets so you have the main wear parts needed when servicing valve and timing systems on 4-cycle vertical engines. It’s built to match the fit and function of common B&S OEM part numbers and supports a wide range of model families and horsepower classes used in lawn tractors, generators, and other small engine applications.

Which engines and models does this camshaft kit fit?

The kit covers numerous Briggs & Stratton engine families and several Toro mower part numbers. It is compatible with multiple engine model prefixes and a range of horsepower designations, making it suitable for many service and restoration jobs.

• Direct B&S part cross-references: 84005207, 793880, 793583, 792681, 791942, 795102.
• Includes replacement items: camshaft, 795387 oil seal, and two 697110 crankcase gaskets.
• Commonly used on engines labeled 21R7–33R8 (10.5–19 HP classes) and similar 4-cycle vertical engines.
• Also fits Toro model numbers such as 74433, 74573, 74582, 71252 and 71253 (ride-on mowers).

What exactly comes in the kit and why each piece matters?

This package gives you the primary camshaft plus the seals and gaskets that typically need replacing whenever the cam is removed or replaced. Using matched sealing parts reduces the chance of oil leaks and speeds up reinstalling the engine.

• One precision-machined camshaft made to match original fitment and timing lobes.
• One 795387 oil seal to protect the crankcase from oil seepage around the cam area.
• Two 697110 crankcase gaskets (also listed as 272475 compatible) for proper sealing when reassembling.
• Packaged as a single kit to simplify parts ordering and ensure compatibility.

How do I verify this part fits my engine before buying?

Match the part numbers stamped on your old camshaft or compare your engine model code with the lists provided. Checking both the part number and the engine model reduces returns and ensures proper fit and timing geometry.

• Inspect the old part for one of the listed replacement numbers (84005207, 793880, etc.).
• Confirm your engine model prefix and horsepower (examples: 21R7, 31R6, 33R7) align with the compatible range.
• Compare physical dimensions and mounting locations if possible, or consult an engine manual for camshaft specs.

What should I expect during installation and post-service performance?

Installation requires basic small-engine disassembly skills: timing cover removal, camshaft extraction, and careful gasket sealing. Once correctly installed and torqued to spec, the new cam and seals should restore proper valve timing and reduce oil leakage typical of worn components.

• Follow engine-specific torque and timing procedures during installation.
• Replace associated wear items (timing gears, lifters) if they show wear for best results.
• Test-run the engine after assembly to confirm correct timing and no oil leaks.

Who is this for: Mechanical hobbyists, lawn and garden equipment technicians, and owners of older Briggs & Stratton or Toro-powered machines who need an affordable, compatible camshaft replacement kit. It’s aimed at anyone performing intermediate engine repairs who wants a matched set (camshaft, oil seal, gaskets) to streamline the job and avoid sourcing separate parts.
