· · Crankshaft deflection is affected by several factors in addition to cylinder pressure.

· Stock crankshafts are engineered to handle typical loads generated by a stock engine, say 250 to 350 hp in a small block V8, or up to 400 hp in a big block V8 with a redline of 5,000 to 5,500 rpm. But there is a limit on how much additional torque and rpms a stock crank can safely withstand if the engine is modified.
· The crankshaft alone can range between a few hundred to several thousand dollars, and labor can vary greatly from one car to another. Labor costs also range from 300 to 800, depending on the kind of car you have and the mechanic's fees. Do I need to polish my crankshaft? If a used crank checks out OK and you intend to reuse it (with no need to regrind), each journal can be polished on .
· This is a used crank a friend bought for a "song" only to discover that when he tool it to the machinist that the thrust surface was undercut (can't see unless you are looking for it). He was quoted 100 for the welding and then another 100 to grind it which is more then a new crank with the 75 he bought the crank for. This is going into a ...
· Yes a puller with a pointed center bolt can expand the crankshaft if hit hard enough. That is just one of the reasons I keep preaching not to belt it with a sledge. An ideal puller (like the OMC) has a flat end on the center bolt, with only a small point to keep it centered on the crank. The flat contacts the crank end before the point goes deep enough to do damage. What to do now is up to ...

If a crankshaft has been overheated, the effect of the original heat treatment will have been destroyed. In this case, the crankshaft should be replaced. If journal scoring is only slight, you can use an oilstone for dressing purposes if you take precautionary measures with respect to abrasives during the procedure.
· After the crankshaft is ground, the oil holes are chamfered and deburred. Then, the crankshaft is polished with a fine grit belt to achieve a satisfactory micro finish. The above process can be used to add more stroke or remove crankshaft stroke. This has been done for years. The 12 o'clock and 6 o'clock positions are offset ground.
· One end of the coupling utilized the lower end of the original engine crankshaft that had the necessary spline to attach to the the outboard driveshaft. The other end of the love joy coupling needs to be replaced with a larger diameter hole that will adapter the to the BS crankshaft. I will try and loe one of those next week. I still have to loe the 4 bolt holes for mounting the ...
Crankshafts are removed from the engine blocks so a visual inspection of the crank casting can be done. Crankshafts with bad keyways, journals spun beyond machining specs or worn thrusts surfaces will be discarded. Adhering to strict quality standards, Promar will never use a welded shaft. Once qualified in preliminary inspection, the crank is then sent for initial cleaning. Dirty Crankshaft ...
