Over torque of the spindle nut will lead to a very hot bearing very quickly. Duane But here’s the exact instruction from X Tighten castilated nut figure 17 to ft. Many references I’ve seen recommend 0. Checker had all the parts in stock and were cheaper than AutoZone. When you look closely at the inside bearings you see “Mexico” on them!!

Versions of the C4 have also been produced for big-blocks. It is one of the easiest automatic transmissions to rebuild and modify because it is so simple and there are a lot of seasoned racers and builders who know a lot about this transmission and how to get it to perform. There are different approaches as to how to build a C4 and what to put in it. Seems everyone has a different opinion about how to build one for street and competition.

Hook-up drawing indicates tubing slopes, position of instrument in reference to process tapping point, scope break between instrument vs piping. Hook-up drawing also gives information the requirement of bulk material for each installation. It also details its specification size, type and material and the quantity. There are two types of hook-up drawing: Process Hook-Up This hook-up drawing contains typical installations for instrument which connects to the process Pneumatic Hook-Up This hook-up drawing contains typical installations for instrument which requires instrument air such as control valve, actuated valve Reference drawing: A good designer can also read whether the instrument tapped in gas service or liquid service.

Installation detail specification will also specify items that should be utilized and factor that should be considered in one installation The purpose of Instrument Hook Up Drawing As stated earlier, information of the requirement of bulk material is stated for installation on each sheet hence the bulk material required for the whole drawings could be summarized and tabulated in a document named Material Take Off.

The normally-open feature insures the home owner that hot water will circulate if there is a failure in the power to the zone valve. Make sure that the direction of flow is correct as indicated by the directional arrow on the valve body. Automag AA zone valves may be installed in any position. It is preferred, however, that AA zone valves be installed on a horizontal line with the coil on top. This is facilitate gravity flow in case of circulator malfunction.

The simplest hydraulic device that you find in common use today is the log splitter. It contains all of the basic components of a hydraulic machine: An engine, normally a small four-stroke gasoline engine , provides the power for the system. The engine is attached to a hydraulic oil pump. The hydraulic oil pump creates a stream of high-pressure oil, which runs to a valve. The valve lets the operator actuate the hydraulic cylinder to split a log.

Pneumatic Directional Control Valves, 2-way, 3-way or 4-way air or solenoid operated.

OEM Considerations Compressor and Reservoirs In the drawing above, the compressor bottom left builds up air pressure as it passes through the air-dryer on to the supply reservoir. The D-2 governor on the compressor keeps the tractor air supply pressure between and PSI. The safety valve on the supply reservoir prevents the air pressure from exceeding PSI. The supply reservoir feeds the other two tanks via a check valve. The check valve prevents the front axle service reservoir and the rear axle service reservoir from bleeding off pressure back to the other tank or into the supply reservoir if one of these tanks should suddenly loose air pressure.

The new CPI SL series is a completely subsea rated version of our harsh duty sensor technology, and can be deployed inside your hydraulic cylinder or accumulator.

Most of the text is specific to the units found on early Mustangs, Falcons, Fairlanes, Galaxies and their Mercury counterparts, but also generally applies to earlier and later versions also. This style unit was used on Fords with “power assisted” steering where hydraulics connected to the steering linkage was used to help turn the car. Over the years it has developed a reputaion for looseness and fluid leakage, but those are not flaws in the design itself but due to age, abuse and neglect.

A properly built, adjusted and maintained system will provide many thousands of miles of trouble-free operation. There are a few things that owners of new reproduction and rebuilt units should be aware of. Knowing these common traits and often made mistakes will help you to better understand the units and how to help them operate efficiently.

Many of the parts inside the control valve itself are continuously bathed in power steering fluid, so there is no need for extra lubrication there. The ball stud area does have a nipple for a grease fitting and can be lubricated as needed. However, the ball stud and bushing moves very little inside the sleeve area so little lubrication is required.

What lubricant is installed during the building of the unit is more than enough to last the through the warranty period and beyond. New units should not require any additional lubrication for 10, miles or so. Since the ball stud area is fairly small, only a small amount of grease is needed to lubricate the pieces.

REAR SPINDLE NUTS. The Maintenance manual is very mis-leading on how to tighten the rear spindle nut. The 25 ft-lbs is only the initial torque to seat the bearing & then it is to be loosen & re-torqued to finger tight or less.

Needs more coolant check when system is cold Do these things: Disconnect vacuum line from control valve and feel under valve to manually move valve to open position. This should let hot water flow through core. If you now have heat inside, replace the heater control valve.

Hook-up drawing is a detailed drawing showing typical installation of instrument in a correct manner so that instrument operates properly (gives accurate indication and prevent any issued which could potentially affect the measurement such as liquid trap in gas impulse line). Hook-up drawing indicates tubing slopes, position of instrument in reference to process tapping point, scope break.

Purpose[ edit ] In the simple case, this can be a relatively simple task as in the internal combustion engine in which the valves always open and close at the same points. This is not the ideal arrangement for a steam engine, though, because greatest power is achieved by keeping the inlet valve open throughout the power stroke thus having full boiler pressure, minus transmission losses, against the piston throughout the stroke while peak efficiency is achieved by only having the inlet valve open for a short time and then letting the steam expand in the cylinder expansive working.

The point at which steam stops being admitted to the cylinder is known as the cutoff , and the optimal position for this varies depending on the work being done and the tradeoff desired between power and efficiency. Steam engines are fitted with regulators throttles in US parlance to vary the restriction on steam flow, but controlling the power via the cutoff setting is generally preferable since it makes for more efficient use of boiler steam.

A further benefit may be obtained by admitting the steam to the cylinder slightly before front or back dead centre. This advanced admission also known as lead steam assists in cushioning the inertia of the motion at high speed. In the internal combustion engine , this task is performed by cams on a camshaft driving poppet valves , but this arrangement is not commonly used with steam engines, partly because achieving variable engine timing using cams is complicated. Instead, a system of eccentrics , cranks and levers is generally used to control a D slide valve or piston valve from the motion.

Generally, two simple harmonic motions with different fixed phase angles are added in varying proportions to provide an output motion that is variable in phase and amplitude.

Grab yourself a stubby, get comfortable and read into the fascinating world of Datsun and other engine valve train operation. Once read a couple of times you will likely understand more about camshafts, valve train geometry and the things affecting them than most of your mates and some automotive engineers as well. Datsport has been extremely fortunate to be permitted to reproduce what is widely recognised at being the best article ever written on camshafts and their operation.
