Q:How many hrs does it take to replace rod bearings?
Ask yourself WHY this need to be done when your engine should last for 300,000 miles WITHOUT needing ANY internal parts. The answer of course is that you have benn using INFERIOR WAX based engine oils. Even now, you PROBABLY do NOT need new bearings, but you DO need an engine flush and switch over to any of the good synthetic oils with a 0 series rating. Your engine life will extend and your bearings will be protected in the coldest weather, even at START_UP, which is where most engine wear actually occurs. TRUST ME, I know!! You shouldn' tneed crank resurfacing, but take the time to platigage the bearings, or have someone who KNOWS what they are doing repair this thing, Usualy a little crocus cloth will clean the crank surfaces perfectly. THINK AHEAD, and LEARN form this experience. USE DEXOS oil of Mobil One or Amsoil in the future. You will save money and your engine sensors and converter will last longest. GOOD LUCK and HAPPY REBUILDING!!!
Q:how can i make my skateboard bearings cleaner and faster?
There are citrus cleaners on the market (you may have some around the house like Desolvit or Goo B Gone or some orange cleaner) which can be used for cleaning bearings with. Not all bearings are serviceable, meaning that you can remove the protective shield on one side. The ones that are usually have a rubber seal on one side and the other is metal. You have to pop off pin holding on the shield and remove it, then remove the ball bearings. You can drop them in the cleaner and wipe out the crud inside the housing, then dry them off good and allow to air dry then re-assemble. After that you'll need some oil or hi-speed grease to pack them with and put back together. For bearings that aren't servicable you have a couple choices, either oil them (which is messy and the dirt will stay inside, but they will be a little faster), or I think they sell some cleaner in a jar for about $8-10 you can drop them in which supposedly cleans them then you have to oil them. But I don't think it works that great Good luck
Q:tandem axel trailor bearings?
If the heat was caused by the bearings, they should be slightly discolored. On my tandem axle car hauler, I installed grease caps with zerk fittings on them. Before each long trip, I get out the grease gun and give each about 15 pumps. Since yours gets exposed to water, I would pull all and repack, looking for signs of corrosion, pitting or rust, and discoloration. Replace as necessary with new seals. Get the greasable caps.

Q:what is hydraulic bearings?
Hydraulic Bearing
Q:Why do so many large railroads (ie,class I) refuse to let rolling stock that has friction bearings............
It's the law. More properly said, cars with friction bearings cannot be received in interchange. This restricts them to home lines. The only time you're likely to see one is on a piece of vintage rolling stock. Outmoded and, frankly, dangerous. They are also susceptible to vandalism. So, no matter how carefully maintained, it will likely never move off of the tracks it now operates on. There may be dispensation of some sort available for a one time, one direction move, but I wouldn't bet on it. So, its gets transported piggy back or on a heavy duty, drop center, flatbed highway truck. Either way, it's gonna take some $$$.
Q:what are the fastest longboard bearings in the world?

Q:Do skateboard bearings come in different sizes?
99$ of skateboard trucks have an 8mm axle and use 608 bearings. Only a few trucks have 10mm axles, usually used for large wheels on longboards. Unless is says 10mm axles on the package, they are the standard bearings.
Q:what kind of bearings are great for speed on skateboards?
Don't use WD-40 it ***** up your bearings. To lube them just take them out of the wheels and usually the inside part isn't covered and just put in Bones Speed Cream or some other skateboard company lube in them. Sometimes the inside part is covered, if it is you might be able to take it off but sometimes you can't and the ones that you can't take them off then you can't lube them.
