Interference Between Clutch Damper and Flywheel Bolts On 2003-2006 Caterpillar 3406E C-15 & C-16 Diesel Engines The AERA Technical Committee offers the following information regarding possible interference between the clutch damper and flywheel bolts on 2003-2006 Caterpillar 3406E, C-15 and C-16 diesel engines. Engines built or serviced with the VCT plus clutch damper, introduced in April 2003, have the possibility of the clutch damper interfering with the flywheel mounting bolts. This applies to the following clutch part numbers: 108009-32Y, 108925-20, 108925-25, 108926-20Y, 108926-25Y, 109701-20, 109701-25, 109705-20Y, 109705-25Y & 109706-32Y. Correction/Action: Any repair that has required the transmission to be removed from the truck, and the engine serial number is 5EK1 and up, 6TS1 and up, 1LW1 and up, 2WS1 and up, 6NZ1-92122, 7CZ1-04382, MBN1-21447, BXS1-00984, 5DS1 and up, or 1MM1 and up, requires checking the flywheel bolt washers. You must verify the 5mm washer has been replaced with the 3mm washer, Caterpillar Part Number 8D-5054. Failure to replace the washers could result in damper rivet interference. Torque the bolts to 270 Nm +/- 40 Nm (200 ft/lb +/- 30 ft/lb). It is also suggested that paint may be applied to bolt heads to show verification and completion identification.

520 CRF 150R and 625 KX 450F 06-08 Flywheel ... - Steahly Offroad

Installation Instructions for CRF 150R and KX450F Steahly Flywheel Weight Warning: Improper instalation of this flywheel weight could result in engine damage or a serious crash. If you do not have the tools or the mechanical abilities take it to a professional. 1. Drain the engine oil or turn off the gas and lay the bike on its side. 2. Remove the shift lever. 3. Remove the ignition cover. Take care not to tear the gasket or have a new gasket on hand. Be carefull that you don’t lose the two dowel pins that are between the cover and the engine case. 4. Remove the flywheel nut. Use an air impact wrench or figure out a way to keep the flywheel from rotating while you remove the nut. A strap wrench or an automotive oil filter wrench may work as a holding tool or try putting the bike in high gear and holding the rear brake on. 5. Pull off the stock flywheel with the proper flywheel puller that has a crank end protection cap. Steahly part number E-63. Do not attempt removal with out the correct puller. Do not use claw type pullers. 6. Fit the flywheel weight on to the stock flywheel. Line up the two threaded holes in the weight with two holes in the stock flywheel. 7. Clean the threads of the two special bolts with contact cleaner. Put a big drop of red Loctite or other high strength thread locker on the threads of the 2 bolts. Install the two special bolts as shown in the picture and torque to 12 foot pounds. 8. Unless you plan to take the weight on and off a lot we highly recommend using a center punch and a hammer to flare out the threads at the end of the bolt (see pictures below). This will reduce the possibility of the bolt coming loose. 9. Clean up the flywheel and weight and remove any metal stuck to the magnets. 10. Install the flywheel with weight back onto the tapered crank shaft end making sure the key ways are lined up. Torque the stock nut to 42 ft- lbs.

Scalable SQL and NoSQL Data Stores - Rick Cattell Home Page

In this paper, we examine a number of SQL and socalled “NoSQL” data stores designed to scale simple OLTP-style application loads over many servers. Originally motivated by Web 2.0 applications, these systems are designed to scale to thousands or millions of users doing updates as well as reads, in contrast to traditional DBMSs and data warehouses. We contrast the new systems on their data model, consistency mechanisms, storage mechanisms, durability guarantees, availability, query support, and other dimensions. These systems typically sacrifice some of these dimensions, e.g. database-wide transaction consistency, in order to achieve others, e.g. higher availability and scalability. Note: Bibliographic references for systems are not listed, but URLs for more information can be found in the System References table at the end of this paper. Caveat: Statements in this paper are based on sources and documentation that may not be reliable, and the systems described are “moving targets,” so some statements may be incorrect. Verify through other sources before depending on information here. Nevertheless, we hope this comprehensive survey is useful!

Ultra-High Performance NoSQL Benchmarking - Aerospike

As companies deal with ever larger amounts of data and increasingly demanding workloads, a new class of databases has taken hold. Dubbed “NoSQL”, these databases trade some of the features used by traditional relational databases in exchange for increased performance and/or partition tolerance. But as NoSQL solutions have proliferated and differentiated themselves (into key-value stores, document databases, graph databases, and “NewSQL”), trying to evaluate the database landscape for a particular class of problem becomes more and more difficult. In this paper we attempt to answer this question for one specific, but critical, class of functionality – applications that need the highest possible raw performance for a reliable storage engine. There have been a few attempts to provide standardized tools to measure performance or other characteristics, but these have been hobbled by the lack of a clear mandate on exactly what they’re testing, plus an inability to measure load at the highest volumes. In addition, there is an implicit tradeoff between the consistency and durability requirements of an application and the maximum throughput that can be processed. What is needed is not an attempt to quantify every NoSQL solution into one artificial bucket, but a more systemic analysis of how some of these databases can achieve under assumptions that mirror real-world application needs. We attempted to provide a comprehensive answer to one specific set of use cases for NoSQL databases -- consumer-facing applications which require extremely high throughput and low latency, and whose information can be represented using a key-value schema. In particular, we look at two common scenarios.

Static and Dynamic Semantics of NoSQL Languages - PPS

that is deduced directly from the structure of the program even in the absence of any explicit type declaration or annotation. We present a calculus for processing semistructured data that spans differences of application area among several novel query languages, broadly categorized as “NoSQL”. This calculus lets users define their own operators, capturing a wider range of data processing capabilities, whilst providing a typing precision so far typical only of primitive hard-coded operators. The type inference algorithm is based on semantic type checking, resulting in type information that is both precise, and flexible enough to handle structured and semistructured data. We illustrate the use of this calculus by encoding a large fragment of Jaql, including operations and iterators over JSON, embedded SQL expressions, and co-grouping, and show how the encoding directly yields a typing discipline for Jaql as it is, namely without the addition of any type definition or type annotation in the code.
