Rover 10: the engine overhaul. | Make boom cranes flying.
I do not know when or how it happened, but the main bearings shells of 6,110,704 gone. Without which the engine, that has a block, but is not worth anything. What to do? I went hunting again, and believe - I could! After three shells are brought mail me: Rover, as the Rover, almost everything is done manually, respectively, have been factory. sion In the case of these shells is a procedure called in line boring and the intention is to erode the centers of the bearings so that they are perfectly straight line - this exclusive crankshaft and bearings are in danger. Centers bearings sion not only be on one straight line, but the line is to be parallel L"gg "box, ie the head, and stood Drills Htzilndrim. It must therefore be a very accurate and it may exist only with proper equipment and proper, and in the hands of a skilled expert, and this matter again below. When we finish adjusting the skins factory checked each bearing number it belongs to, the direction of the assembly, and the number of series production engine (and 681D engine refurbishment process). As you can see, the shell No. 1 engine taken No. 186, No. 2 engine 161, and No. 3 engine 794 - Horde. Therefore, the current renovation will require us to repeat the process in line boring from the start. sion The next item on the completion of the equipment are rods (rod tribal language of shaking). Special susceptibility of these ancient compared to modern rockers are cast in white metal bearings in them: The picture shows four rods used, worn bearings (but not spilled) inside. During his long years with Rover I made several abortive attempt to replace the bearings and bearings molded thin shell, such effects in modern engines. Here domes shook both types side by side: the Rover engine, due to lack of oil filter on-line, only the bearings are molded sion longevity. With shell bearings survived thousands sion of miles individual box, and bearings are cast, the treatment is right, he can go a hundred thousand miles and more. To complicate life (and because of the constraints of lack of raw materials after World War), created the Rover two types of connecting rods, and they Mkt"im difference. They differ in weight - almost 50 grams of 700. Consequently, the engine will consist of connecting rods of both types is not will be unbalanced and suffer tremors sharp while running, and life expectancy is reduced., when ingredients engine is not partial "organic", as in the case for the current,, make sure bad all rods will be only the same type, which I did, I chose carefully from the selection held by the way, bearing Portability is the first row ball bearing "pour", those interested predict such BEARING. melting point of the white metal is low and all the motor overheating can result in melting and "sfichth. "over-molded bearings are worn or just not the right size., and now we come to the dilemma best solution: sion valve lifters. actuator output shaft 8 small cylinders (102), which in turn are raising the bar is running a "Canaanite Piano" (101) in the painting above. these pistons and valves are called lifters (tappets) sion and moving their own small cylinders drilled in the block. these holes, approximately 20 mm in diameter, were covered with mud and rust. Some also were scratched, male violence, which were lifting them old, with a chisel and hammer. The first step is to etch holes rehabilitate them and increase the diameter. The valve lifters to fit tight fit, up to a few thousandths of a mm, drill, and it is clear that after this engraving will not fit standard lifting coordinators. What makes the problem worse is that none of the twenty sion - thirty lifting hands is not a "standard." First of all because everyone worn , and some rusted and damaged. then set typical sion of lifting used: it seems their bottoms, those coming into contact sion repeatedly with output shaft: So our task consists of two tasks: first: to rehabilitate bores lifting, sion and the second: rebuild are raising themselves, and adapt them to the new drills. impossible to enter with a reamer, drill or knife carving holes are from the outside of the box. because they are outsiders: sion the right hole completely hidden. both from within is difficult to access them: oil distribution pipes (1 and 2) block access sion to it, so the first step in solving the problem was the extraction of these stacks displaced, sion as described in Chapter Three. Now all holes are accessible and can bring them to normal. personnel "Artist" said they are unable to make sleeves drills are to be returned to the nominal diameter. discussed Robert experts England what to do about it - and found their solution. then what do we do? One option is to refurbish the existing lifting and watch them in hard chrome. This option is checked now in practice. Another option, the last resort is to produce such new extent necessary - and it turned only if there is no other choice. NEXT
