What is the purpose of feeler gauge?
Feeler gauges consist of thin slivers of metal which are graduated in thickness, probably from 0.003 ins up to 0.030 ins (ie 3 thou to 30 thou). This is assuming they are calibrated in inches, or they could be in mm. 3 thou would be about 0.075 mm and 30 thou would be 0.75 mm. You just find the appropriate thickness for the gap you have. Start with one thinner than the gap and work up until you find the one that just fits. Don't force the gap by trying to put in one that is too thick.
When on a sailboat under power of a small motor do you lash the tiller and steer by motor or keep the motor straight and steer by tiller?
This is a WAG from a power boater, not a sailboater, but...I think there are two things to consider. (assuming you don't have remote controls for your kicker) First, how accessible is the outboard? If the outboard is so far aft of the cockpit that you can't reach the tiller (or wheel) then you will need to be with the engine for forward/reverse control and speed control. On the other hand, if your outboard is close enough to the rudder control to use it, the rudder has much greater surface area and you would have more steering control using the rudder. Just an educated guess. Good luck. From a sailor- On my boat I steer by rudder and leave the motor amidships for normal motoring But the outboard, with its directional thrust, is very handy when in tight quarters especially at low speeds when the rudder is less effective. I have an extension for the motor control handle to make it easily accessible from the cockpit.
Valve clearance of volvo f12?
Valve clearance of Volvo f12, are set using a feeler gauge on the lash adjuster.
What is the gap ratio for lifters in 1989 Chevy 350?
That would be zero valve lash. You only use a feeler gauge on solid lifters.
What tool do you use to measure valve lash?
Feeler guage. Looks like a pocket knife and contains numerous small metal strips of varying thicknesses
How do you adjust valves on 6 hp Briggs and stratton engine?
You have to set the piston at Top Dead Center (TDC). I beleive the lash adjustment (valve clearance) is .004 to .006 in. That means thousandths. Once you have set piston at TDC (valve springs will not be compressed but extended on the compression stroke at TDC). You can now set the lash adjustment by loosening the set nut and bolt. You need a feeler gauge to do this. Set lash on both valves then recheck.
How do over head valves on diesel engine are ajusted?
Do you mean valve "lash?" (The slack between the closed valve and the cam base circle.) That is adjusted the same way as on any other engine. Remove the valve cover and locate the adjustment screws on the rocker arms. Turn the crankshaft to position the rocker on the base circle and check the gap with a feeler gauge. Repeat for each valve.
Do you adj valve lash ON A 2003 HONDA ACCORD 4CY?
To do a valve lash on a 2003 Honda Accord make sure a lash gauge is on hand. Valves lashes adjust the valve to piston clearance on cars. Be sure to use the appropriate specifications of clearance for the 2003 Accord.
What is the gap number on valves for a 1600cc engine?
Set your valve lash to 0.006". You actually need two feeler gauges to do this--a .006 "go" gauge and a .008 "no go" gauge. When the .006 goes in and the .008 won't, you've got it. They used to say set the exhaust valves to .004. You tend to break valves at that clearance.
How do you adjust 22r valve lash?
You need a "feeler gauge" and a wrench to do this. They say to adjust the valves with the engine fully warmed up. So drive it around for 30 minutes before starting this adjustment. Set the crankshaft on TDC and you can adjust half of the valves. Rotate the crankshaft 360 degrees and you can adjust the rest. If the spec is say .025 get that thickness feeler gauge ready. If you do not have an .025 gauge a .012 and .013 together is just as good or a .020 and a .005 will work. Slip the gauge in between in rocker arm and the valve stem. If you cannot do this the valve is too tight. To do it correctly you move the feeler gauge back and forth while turning the adjusting nut slightly until you begin to feel resistance in the gauge. you want some resistance, enough so that you can move the gauge back and forth without too much effort, but not to where you cannot move it at all or to where you can move it freely. Hence the name feeler gauge as you feel how the gauge passes in between the rocker are and valve stem. Once you have it where you like it, tighten the lock nut to spec's. Once the lock nut is tight, you must recheck the valve clearance to make sure nothing changed while setting the lock nut. If it feels the same as before move on to the next valve. If it feels loose or if you cannot get the gauge back in, you must start over. Loose valves will make noise, tight valves will destroy an engine. Do it correctly or pay the price.
How much torque lbs should the rocker arms be set at?
most rockers do not have a torque spec depends on the engine some have a lash spec which has to be set with a feeler gauge but it is different for every engine
Mazda b2000 tapping noise?
The Mazda B2000 was equipped from the factory with mechanical lash adjusters. These need to be adjusted about once a year to maintain proper lash between the lash adjuster and the valve tip. To get to the rocker arms remove you're valve cover. In order to make an adjustment the cam follower must be on the base circle of the came lobe. Turn the engine clockwise until the cam lobe for the rocker arm you are trying to adjust is pointed straight down. Then loosen the lock nut and back off the adjuster with a flat head screw driver, insert the feeler gauge between the adjuster and valve tip. Slowly tighten the adjuster while wiggling the feeler gauge until it is snug to move. Then carefully hold the adjuster steady with the screwdriver as you tighten the lock nut with the wrench. Set the intake rocker arms for .007" lash and the exhaust side for .008" After you are done turn the engine clockwise two full revolutions and then check to make sure on the intake side you can fit the .007" feeler gauge but not the .008". Do the same for the exhaust side making sure you can fit the .008" but not the .009". If the larger gauge fits for any rocker arm readjust it turn the engine over twice and recheck. Some tapping will always be heard with mechanical lash adjusters. The above settings are my recommendation based on professional experience. If set properly to the settings above valvetrain noise and wear will be minimized. The factory recommended setting should be labeled on a sticker under the hood. Kyrasis6 Owner of Mazdatruckin.com
How do you run overhead on a c12 cat engine?
Finding TDCRemove two bolts (1) and remove cover (2) from flywheel housing (3) in order to open the turning hole.Put one 6V-5219 Bolt (1) in the timing hole. The timing hole is located approximately 127 to 152 mm (5.0 to 6.0 inch) above the turning hole in the flywheel housing. Use the 9S-9082Engine Turning Tool and a 1U-7115 Reverse Ratchet to turn the engine flywheel. Turn the flywheel in the direction of engine rotation. The direction of engine rotation is counterclockwise, as the engine is viewed from the flywheel end. Turn the flywheel until the timing bolt engages with the threaded hole in the flywheel. Note: If the flywheel is turned beyond the point of engagement, the flywheel must be turned in the direction that is reverse of normal engine rotation. Turn the flywheel by approximately 30 degrees. Then turn the flywheel in the direction of normal rotation until the timing bolt engages with the threaded hole. This procedure removes the play from the gears when the No. 1 piston is at the top center position.Remove the front valve mechanism cover from the engine.The inlet and exhaust valves for the No. 1 cylinder are fully closed if No. 1 piston is on the compression stroke and the rocker arms can be moved by hand. If the rocker arms cannot be moved and the valves are slightly open, the No. 1 piston is on the exhaust stroke. Note: When the actual stroke position is identified, and the other stroke position is needed, remove the timing bolt from the flywheel. Then turn the flywheel by 360 degrees in the direction of normal engine rotation and reinstall the timing bolt.Injector adjustmentTo make an adjustment to the unit injectors on cylinders 3, 5, and 6 use the following procedure:Put the number 1 piston at the top center position on the compression stroke. Refer to Systems Operation/Testing and Adjusting, "Finding Top Center Position For No. 1 Piston".Turn the unit injector adjusting screw (2) clockwise until contact is made with the unit injector.Turn the unit injector adjusting screw through 180 degrees in a clockwise direction.Hold the adjusting screw in this position and tighten the locknut (3) to a torque of 55 ± 10 N·m (41.0 ± 7.0 lb ft).To make an adjustment to the unit injectors on cylinders 1, 2, and 4, remove the timing bolt. Turn the flywheel by 360 degrees in the direction of the engine's rotation. The engine rotates in a counterclockwise manner. This will put the number 1 piston at the top center position on the exhaust stroke.Repeat 2 through 4.Remove the timing bolt from the flywheel after all of the unit injector adjustments have been made.

How do you adjust solid tapped lifters on small block 350?
with a socket wrench and a feeler gauge. Set the valve lash to the manufacturer's specifications. Most lash adjustments are done "hot" (with the engine at full operating temperature) so keep that in mind. I usually set the lash 1 or 2 thousandths loose for the initial cold adjustment when dealing with a newly installed cam shaft, rocker arms, etc. You're better off being a tiny bit loose than you are being too tight.
