Hi ToryC,
This is what I saw online might be worth a try.
✅ 1. Penetrating Oil + Time (Not WD-40)
Use a proper penetrant:
Kroil
PB Blaster
CRC Freeze Off
Inox MX-5
Soak the shaft where the cone meets it from both ends if possible.
Let it sit overnight—this alone sometimes breaks the bond.
✅ 2. Apply Axial Heat (But Carefully)
The cone is mild steel; the shaft is hardened.
You want to expand the cone, not the shaft.
Method:
Use a MAP gas torch (preferred) or propane.
Heat only the outer cone hub, keep heat away from the thrust pad area.
Heat slowly and evenly until it’s too hot to touch but not red-hot.
Quickly apply more penetrating oil (it will wick in as it cools).
🔥 Do NOT heat the shaft directly—you can ruin its hardness.
✅ 3. Use a 2- or 3-Jaw Puller—But With a Spacer
If you grab the edges of the cone without supporting the PTO shaft, you risk:
bending the shaft
collapsing the cone
damaging the bearing or crankcase
Proper setup:
Put a short, thick bolt between the puller center screw and the PTO shaft end so the shaft isn’t mushroomed.
Position jaws under the meatiest part of the cone, not the edge.
Tighten preload, then:
tap the cone hub LIGHTLY with a hammer (to shock it),
tighten a little more,
tap again.
These cones usually release with a loud POP.
✅ 4. The “Heat + Puller + Shock” Combo (Most Effective)
Heat the cone hub as above.
Apply tension with the puller.
While under tension, strike the hub sharply radially (sideways) with a brass hammer.
This breaks corrosion bonds extremely well.
✅ 5. If You Have No Puller: The Wedge Trick
Last resort—only if you accept risk of replacing the cone.
Heat the cone hub.
Insert two opposing cold chisels or pry wedges behind the cone (NOT between cone and thrust pad).
Tap them in evenly, alternating sides.
⚠️ This method can crack cones, so use only if replacements are available.
❗ Avoid These Mistakes
Do not hammer the shaft end directly (it will mushroom and trap the cone forever).
Do not apply red-hot heat (you’ll wreck the temper of the shaft).
Do not pry against the crankcase.
Do not clamp vice grips to the shaft—scratches create future binding.
🧼 After It Comes Off
Clean everything:
Wet-sand the PTO shaft with 800–1200 grit
Polish with metal polish
Apply anti-seize before reassembly (very important!)
Check:
Cone bore for scoring
Thrust pad flatness
PTO shaft straightness
Keyway condition
Cheers
Max.
