A needle roller bearing is a bearing that uses small cylindrical rollers. These rollers are used to reduce friction of a rotating surface. Compared to ball bearings, needle roller bearings have a large surface area that is in contact with the bearing raceway journals.

With the journals measured, it’s time to set up a dial bore gauge to measure the inside diameter of the rod bearings. To begin, we set up our dial bore gauge at slightly more than 2.100-inches to establish a load on the gauge. We then set our micrometer at 2.100-inches and placed it in a protected vise to hold it secure while we set the dial bore gauge indicator up to read zero (0) at this 2.100-inch spec.

Although Ing. Klauer joined BMW Motorrad from its parent company’s automobile division only five years ago, he insists that this all-new system owes nothing to the Vanos variable valve timing technology developed 25 years ago for use on BMW cars, nor the Valvetronic variable valve lift system introduced in 2001, both of which were considered too bulky for motorcycle use. Instead, the R1250GS engine’s cylinder heads feature the all-new, highly innovative ShiftCam system, which combines both variable valve timing and differential valve lift, all in the same package, as a means of optimizing cam timing and duration for what you’re asking the engine to do. For part-throttle openings, or lower down in the rev range, the cam has a shorter lift and reduced duration, meaning the inlet valves are open less. But ask for more throttle or higher revs and the cam shifts sideways, bringing into play a higher lift, longer duration cam lobe, more suited to outright performance.

“It’s just nobody’s really had the guts to go through and make a mainstream passenger car with something other than carpet, at least not recently,” Torchinsky said. “I feel like so much of what stops people from doing that are these ideas that rubber is not premium enough, like I don’t know when we all decided we were royalty worthy of being coddled in every product we have, and everything that we encounter has to be the absolute best, but it doesn’t always. Sometimes the best isn’t the most luxurious; sometimes it’s the thing that just does its job the best.”

When you really start fine-tuning your 3D printer, you might start to notice that even the smallest things can have a noticeable impact on your prints. An open window can cause enough of a draft to make your print peel up from the bed, and the slightly askew diameter of that bargain basement filament can mess up your extrusion rate. It can be a deep rabbit hole to fall down if you’re not careful.

When mixing shell halves, the rule is to place the thicker shell half into the loaded side of the housing bore. So in case of a main bearing, the thicker shell half would be placed in the main cap, while in a connecting rod the thicker half would be placed in the upper position with the rod. This creates a situation where, under load, the oil clearance decreases on the loaded side so the thinner shell half allows more room for the oil to enter the bearing area and maintain lubrication.

I was splitting wood one day a few years back, getting next winter’s firewood ready on my hydraulic splitter. It normally handled my ash and oak with ease, but I had a particularly gnarly piece of birch queued up, and the splitter was struggling. The 20-ton cylinder slowed as the wedge jammed in the twisted grain, the engine started to bog down, then BANG! I jumped back as something gave way and the engine revved out of control; I figured a hydraulic hose gave out. Whatever it was, I was done for the day.
