Three different blocks were used in the various iterations of the 466. Up to that point the fan clutch was a stud mount and had the smaller nut that was right hand thread. Along with completely straight frame rails, the chassis was designed with a flat-back firewall, allowing for body mounting with minimal design adaptations. This design is commonplace in larger displacement diesel engines and is considered one that enhances durability because the consistent wall thickness of the sleeve allows for even heat transfer, ensuring the cylinders stay round during thermal expansion. This engine is so versatile that it is found in farm tractors, dozers, fire trucks, and without question is the most popular school bus diesel engine.
Brand Info x Close Every Reliance part is produced to exacting standards to ensure the same or better reliability as the original part. Details: Please note: There is a specific range of 469H prefix engines where engine horsepower amount is the same, but torque is different. Sharing powertrain and chassis components with the 3800, the 3000 was designed for both V8 and inline-6 engines from multiple manufacturers. For 1991, the 3600 chassis variant was developed for the semi-forward control conventional. For model year 2000 and newer units the serial location was moved to the right side of the cylinder block between the oil cooler and top of the block. Otten, the Customer Relations Manager, P. To get a better understanding, here is a basic breakdown.
The 466 engine is an inline six cylinder wet sleeve block that has six upper counter bores and six lower packing areas where the rubber seal is installed. Piston cooling jets bolt into the main oil gallery of the block and spray oil into the bottom side of the piston for cooling of the head of the piston. Gillig Coach 1979-1981 The last Gillig Type C bus Gillig Coach School Bus was built in 1981; very few were produced. In production for over 25 years, the S-series bus chassis was the longest-lived model line ever produced by International and the final Navistar product line developed by International Harvester. These sleeves are prefinished and do not require honing after installation. It was sold for industrial purposes as the V-605. In comparison to the 3800, the driver of the Vista sat further forward shifted nearly atop the front axle instead of behind it.
Remanufactured clutch and non-engine parts are warranted to be free from defects in material and workmanship under normal service and operating conditions for a period of six months from the date of installation without limitation on miles or hours of operation. A post-war version of the 269 cubic inches 4. The medium-duty 1930 A-series trucks received the all-new 278. The 466, however, being a high production mid-range diesel, is somewhat unique in its wet-sleeve design, because nearly all the other high production mid-range engines are in-place cylinder blocks. The Importance of Your Navistar Engine Serial Number Engine serial numbers are incredibly important when you have a heavy duty diesel engine. With advanced electronic notification, a 100% satisfaction guarantee and an easy opt-out plan, the Square Deal Subscription Program is the best value, risk free, eco-friendliest way to subscribe. This is a deep saddle casting where the crankshaft lies completely inside the block.
The forging number of the connecting rod 688922 stayed the same throughout the engines. This gutsy move paid off since neither bearing failures nor crankshaft breakage are at all common to this engine. There you have it: the 466 Legend engine. In line with a transit-style bus, the driver sat next to much of the engine; access from the front was also maintained via a tilting hood shortened in length by nearly half. This means that the cylinder wall sleeve is a separately machined part that fits into upper counter bores for sealing at the top with O-ring housing bores cast into the engine block in the bottom.
For those looking to use the larger pump on the B models, the crank pulley that was made for the 1? These wore vertical grille slats instead of horizontal ones seen since 1989 although the horizontal grille slats continued to be produced for the 3800 until 2004. You will also need the engine model, model year, horsepower rating, and torque rating, which can all be found on the emission label. Agricultural applications used the same casting but the timing pointer is in a different clock position. A key event that would affect school bus manufacturing during the later 1990s was the completion of the acquisition of by in April 1995. The 210-horsepower engine produces peak horsepower at 2,300 rpm and 520 pound-feet of torque at 1,400 rpm. In addition, the cowled chassis formed the basis for front-engine and rear-engine stripped chassis produced for bus applications.
For 1995, International consolidated the two model lines, discontinuing the 3700. They also allow for easy in-frame overhauls during service. This affected how the exhaust pipe was connected to the turbo and obviously cannot be interchanged without making other major changes to the exhaust system. Please keep this in mind when ordering. Oil Pumps There were three oil pumps in the Legend series of engines. Navistar keeps the location pretty simple. In 1990 it changed from a sleeve-style flange to a Marmon flange Figure 12.
Has any one ran in to this problem before. While produced as a bare chassis, the model line shared the steering column and instrument cluster from the S-series conventionals. For most Navistar engines that were built after 1993, you will need more than just the engine serial number as well. The 220-horsepower engine produces 540 pound-feet of torque; the 225-horsepower version produces 560 pound-feet of torque; one 245-horsepower version produces 620 pound-feet of torque and the higher-end 245-horsepower version produces 660 pound-feet of torque. The flat lifter camshafts can be built up and repaired as shown in Figure 6. Unlike the S-series conventional, the chassis was powered exclusively by a diesel engine; the 9.
How to Find a Navistar Engine Serial Number The engine serial number for Navistar engines can be found stamped on a pad on the block. Camshaft There are three camshafts Figure 5 that correspond to the three different blocks. Serial Letters Assigned To 'Milwaukee Works' Ouput of Engines and Tractors by Year December 11, 1922 Serial Letter Assign'd Shop s From To Year Mfg A 1-? A 4-speed manual was standard on the S1700 variants, while S1800 variants were equipped with a 5-speed manual; a 4-speed automatic was optional on all engines. This article needs additional citations for. The first generation chassis saw use by many manufacturers across North America, as did the 3800 during most of the 1990s.
