Crankshaft Rebuilding for Motorcycles ATV and Snowmobiles
At LaBaron's Power Sports, we rebuild crankshafts for many applications, including snowmobiles, ATV, dirt-bikes, side by sides, both 2-cycle and 4 cycle, single cylinder, and twin cylinder. Our experience and precision in crankshaft rebuilding is unmatched in the industry at any price, and we can deliver a rebuilt product that will meet and exceed any O.E.M. crank. We also offer remanufactured crankshafts on an exchange basis for the models that we do not rebuild in-house.
- *Single Crankshafts - *$99.00 + parts
- Polaris Snowmobile Twin Crankshafts - $295.00 + parts
- Re-manufactured crankshafts for most applications - Call or email for Pricing
- New Crankshafts for certain applications - Call or email for pricing
* Some single cranks have large timing gears, counter balance gears or a thin tin-can crank web (Honda). These will require additional labor ($44.00) to remove and reinstall them during the rebuilding process. If your crank has damaged live centers, there will be additional labor for truing the crankshaft ($44.00)
A Rebuilt Crankshaft will make your Engine Reliable
Crankshaft rebuilding is precise work. It requires an experienced technician and several thousand dollars worth of sophisticated tooling and equipment to do properly. LaBaron's Power Sports has been rebuilding crankshafts for motorcycles, ATV and snowmobiles for years. Our reputation for precise work and adhering to exact tolerances is what keeps this business growing.
Keep in mind, a crankshaft that is assembled using quality parts and then trued beyond the factory specifications (in most cases less than .001" run out) will outlast and outperform a factory re-manufactured crank or even a new OEM crankshaft. So if you're looking for a quality hand assembled crankshaft that will last in your motorcycle, LaBaron's Power sports is the only shop you need to know.
In many cases, new aftermarket and O.E.M. crankshafts have larger tolerances. We have experienced as much as .004" - .006" radial run out on NEW crankshafts. These loose tolerances can cause excessive vibration, shortened life of bearings, and loss of power due to parasitic drag. We are not satisfied until we achieve a run out of less than .001", thus increasing performance and durability far beyond that of new crankshafts.
Some machines are known for crankshaft issues and failures, most notably Polaris 800cc liberty twin and Ski Doo 800cc cranks, Honda 450cc crankshafts and Polaris Sportsman 700 cranks. We have the specialized equipment and experience to rebuild several model crankshafts. We have access to billet steel PTO ends, larger quality bearings, lightweight heavy duty connecting rod kits, and more...
Frequently Asked Questions
Q: Can you grind or machine my one-piece crankshaft and fit undersized bearings?
A: No. Currently we do not possess the specialty equipment required to resurface (Weld & Grind) cranks.
Q: How do I know if my crank is a press-together style or a one-piece?
A: If your connecting rod(s) are bolted together at the bottom, then you have a one-piece style crankshaft.
Q: Can you rebuild my Harley Davidson Crankshaft?
A: We currently do not perform any Harley Davidson engine work.
Q: What is a Tin-Can Style crankshaft?
A: Tin-Can style crankshafts were used by Honda on 125, 250, and 500cc 2-stroke engines. These crankshafts have a thin steel skin and take much more time to true without damaging the skin.
Q: Can you rebuild my vintage crankshaft?
A: We no longer rebuild any crankshaft 1989 or older.
