🛠️ Mechanic's Tip:
Whenever you split the crankcase to replace these bearings, it is highly recommended to also install new crankshaft oil seals. This prevents air leaks that can lead to lean-running conditions and engine failure.
🛠️ Professional Installation Tip: The "Heat & Cold" Method
For a perfect, stress-free installation into the TS410/TS420 crankcase, pros use thermal expansion rather than force:
- Freeze the Bearings: Place your new bearings in a freezer for 1-2 hours. This slightly shrinks the outer race.
- Heat the Case: Use a heat gun to gently warm the bearing pocket in the aluminum crankcase.
- Drop-In Fit: The chilled bearing will often drop right into the heated case without using a press, preventing damage to the bearing races or the case alignment.
- Final Check: Once the case cools, ensure you install new Crankshaft Oil Seals to prevent air leaks that cause lean-running and engine seizure.
