Honda pcx 2013 Engine seizing up?
I'm currently using a friends honda pcx it cut out a couple days ago and I thought the starter motor went because it wouldn't crank over today I took it apart to check what's wrong and the crankshaft was seized in place I cracked it out of bring stuck and the bike started quite nicely then after about 30 seconds seized up again… Did that every time I unsiezed the engine. I'm going to rebuild the engine before giving it back to my friend but just wanted to know what the most likely thing could be. I have a rough feeling it's crankshaft related but I'm not sure what the 3 sprockets on the crankshaft are and wondered if there could be something jamming do do with the sprockets. Anyway I'll be fixing it either way and my friend doesn't mind about the bike as he's been letting me borrow it for around 6 months now… Anyone know what it could be like oil pump or anything?
Usually the crank main bearings seize due to lack of oil OR abuse so pick one.
Do not guess. Just tear it down and find the bad parts. Get a caliper. The bearings are most likely shot. These bikes are almost bullet proof but a lack of oil or oil changes kills all engines. The oil pumps on these bikes rarely go bad.
This is a four stroke motor and as such requires oil in the crankcase. Some one might have thought it was or is a two stroke and treated it as such.
I never reuse a crankshaft that has seized unless it is turned and fitted with new bearings. Care needs to be taken when putting the bearings back in to make sure the holes line up for oil distribution. Use the right bearings for the turned crankshaft!
I suspect that the failure to get the crank shaft resurfaced caused the second failure. Remember to pre-lube the bearings.
Make sure the crankcase oil level is right!
- My 2013 Honda Pilots VTM-4(4WD mode) and Check engine light are on? A few miles latter I restarted the engine again, a few times and only the Check engine light was on. After driving a mile or so I turned off the car and started a couple of minutes later but this time no lights were on. A few miles before those two light went on, it felt like the car kind of jolted a little but I'm not too sure if it was an engine misfire or a pothole.
- Replace battery on my honda pcx 125 scooter? Can I replace the 12V 6Ah battery on my 125cc scooter with a 12V 5Ah battery, without causing damage to the sckooter
- I have a 125 honda pcx scooter? When I pull away I hear a noise from the left sounding a lot like a fan belt noise in a car. Its a 2012 scooter done 7400 miles always had a service.sometimes you don't hear the noise in the sun but wet weather you seem to hear it more.once you pull away the noise goes. When I put bike on stand you can't hear it, its when you sit on bike and pull away.
- Honda pcx crankshaft locks under throttle? My friends pcx blew and the crankshaft seized we un seized it with a breaker bar to find out it spins smoothly but when you open the throttle it cuts out and the crankshaft locks up straight away? Is there a throttle activated oil pump in these or what could it be. I'm used to working on 2t bikes done plenty of rebuilds & as far as 4t bikes I've only done dirt bike engines which aren't fuel injected… Does anyone know?
