The Bombardier DS650 is a powerful and popular ATV, but like any machine, it requires regular maintenance. One of the most crucial and potentially costly repairs is a crank rebuild. This guide will cover everything you need to know about Bombardier DS650 crank rebuild services, from understanding when a rebuild is necessary to finding reputable shops and considering DIY options.
When Do I Need a Bombardier DS650 Crank Rebuild?
This is the first and most important question. Ignoring the early warning signs of a failing crank can lead to catastrophic engine damage and a far more expensive repair bill. Several indicators suggest your DS650 crank needs attention:
- Unusual Engine Noises: Rattling, knocking, or grinding sounds coming from the engine are significant warning signs. These noises often indicate bearing failure or crankshaft damage.
- Low Compression: A significant drop in engine compression indicates a problem with the seals or the crank itself, potentially requiring a rebuild.
- Excessive Engine Vibration: More vibration than usual suggests a problem with balance, often related to crankshaft issues.
- Oil Leaks: Leaks around the crankcase can indicate seal failure, a precursor to more significant damage to the crank.
- Seized Engine: If your engine has completely seized, a crank rebuild is almost certainly necessary. This is the most severe scenario and often requires complete engine overhaul.
What's Involved in a Bombardier DS650 Crank Rebuild?
A professional crank rebuild is a complex process usually best left to experienced mechanics. It typically involves:
- Disassembly: The engine is carefully disassembled to access the crankshaft.
- Inspection: A thorough inspection of the crankshaft for wear, cracks, scoring, or other damage.
- Repair or Replacement: Damaged parts are repaired or replaced, including bearings, seals, and possibly the crankshaft itself. This might involve balancing the crankshaft for optimal performance.
- Reassembly: The engine is meticulously reassembled, ensuring proper tolerances and clearances.
- Testing: After reassembly, the engine is tested to ensure proper function and performance.
How Much Does a Bombardier DS650 Crank Rebuild Cost?
The cost of a crank rebuild varies widely depending on the extent of the damage, the shop's labor rates, and the parts required. Expect to pay anywhere from several hundred dollars for minor repairs to several thousand for a complete crank replacement. Getting multiple quotes from reputable shops is crucial to getting a competitive price.
Can I Rebuild My Bombardier DS650 Crank Myself?
While theoretically possible, rebuilding a crankshaft is a highly specialized and technically demanding task. It requires extensive mechanical knowledge, specialized tools, and a clean, well-equipped workspace. Attempting a DIY rebuild without the necessary skills and equipment can easily result in further damage and increase repair costs significantly. Unless you have significant experience working on engines, it is strongly advised to leave this to a professional.
Where Can I Find a Reputable Bombardier DS650 Crank Rebuild Service?
Finding a reputable mechanic is crucial. Look for shops specializing in ATV repair and those with positive customer reviews and testimonials. Don't hesitate to ask about their experience with Bombardier DS650 engines and crank rebuilds specifically. Ask about their warranty and the parts they use.
What Kind of Warranty Should I Expect?
A reputable shop will offer a warranty on their work. The length and terms of the warranty will vary, so be sure to inquire about this before proceeding with the repair.
Are there preventative measures to prolong my crank's life?
Regular maintenance is key to extending the life of your DS650's crank. This includes using the correct oil and changing it regularly, following the manufacturer's recommended service schedule, and avoiding extreme riding conditions that could put excessive stress on the engine.
By carefully considering these factors and following the advice outlined above, you can ensure your Bombardier DS650 receives the best possible crank rebuild service, keeping it running strong for years to come. Remember, prevention is better than cure; regular maintenance can significantly reduce the likelihood of needing a costly crank rebuild.
