I just pulled the motor and the thrust bearing was COMPLETE TOAST. If my engine has the narrow early style when it should have had the later wider style, I'm gonna … He filed for a patent in 1907, and it was granted in 1910. ProFlange® is a line of bearing sets supplied with oversized flanges, allowing the thrust surface to be ground to 0.010″, 0.020″, or 0.030″ undersize. Thrust Bearing - Thrust Cut Measurement: The thrust surface of the VW engine is at the flywheel side main journal. The tangs are offset from center to aid correct insertion. If the bearing is folded too far, or not far enough, it will not have proper thrust contact. 50, 00MM. The thrust bearing face can wear like the main surface. If there is enough space on the rod journals, worn-out thrust bearings can enable the crank backward enough to jam the torque converter into the transmission or move forward or backward enough to result in excessive edge-wear on the belts. Chances are the thrust pieces are laying in your oil pan. This is a brand new Set of: Silver Line Steel Backed Main Bearings for VW Type 1Engine: VW Type 1 40HP, 1300, 1500 1600Sizes available: in "Inches"STD Case / STD CrankSTD Case / .010 CrankSTD Case / .020 CrankSTD Case / .030 Crank.020 Case / STD Crank.020 Case / STD Crank / Thrust +1mm (+ $5.00).020 Case / STD Crank / An increase in the number of times a crankshaft has been ground can help increase the thrust width. The factory Thrust bearing is a 3 piece bearing. Genuine 2018 MINI Part # 11219470157 (11-21-9-470-157) - Crankshaft thrust bearing lower 2. The upper and lower bearing shells are located in the respective block and bearing cap by a tang. During regrinding a common practice is to “kiss” the rear thrust surface to clean it up. Ships from Seattle MINI, Seattle WA If it is moving as much as you say, there has to have been some contact somewhere. Fluid-film thrust bearings were invented by Albert Kingsbury, who discovered the principle in the course of bearing and lubrication investigations commencing in 1888 while a student.His first experimental bearing was tested in 1904. The first Kingsbury bearing in hydroelectric service, one of its major applications, was … Crankshaft Thrust Bearings (T029A-STD) by Taiho®. The bearing that sits there, along with the flywheel and flywheel shims, limit how much the crankshaft can move back and forth in the case. Crank end play was .085 and there is a deep groove in the crank thrust surface. The tang is located at the parting line at one end of each bearing shell. To align the rear cap, we placed feeler gauges between the top and bottom of the bearing flange, or the side of the thrust bearing. This top-grade product is expertly made in compliance with stringent industry standards to offer a fusion of a well-balanced design and high level of craftsmanship. Mount a magnetic base to the engine and set the dial indicator to read off the crank snout. Main Bearing Caps, Bearing Shells and Crankshaft Thrust Washers. It can be replaced without pulling the motor, but I would guess you may need some crankshaft work. After a number of “kisses” the clearance can be excessive. Gently pry the crank all the way forward and zero the gauge. Extra Insurance Against Engine Bearing Failures As crankshaft thrust surfaces and main bearing flanges begin to wear, the crankshaft can move longitudinally or “walk,” causing Figure 1. In some cases crankshaft thrust surfaces have to be ground for an oversized thrust bearing. This is the amount of clearance between the crankshaft’s thrust plate and the vertical surface of the main thrust bearing.
