When do you switch to an adjustable valvetrain?
If we switch to solid lifters it is mandatory that we convert to an adjustable valvetrain (I would also say that converting to adjustable valvetrain is mandatory in ALL racing applications as well as any application where we want to have accurate control of our valve lash setting). Not doing so is asking for serious problems!

When do you need to adjust the Lash setting on a valve?
Do not rely on the below list. If the position of the lifter on the camshaft lobe is anywhere other than on the heel (note image above) where there is NO ramp contact when making adjustments, the lash setting will be incorrect. This position is required for each valve before you attempt to perform adjustments.

Where is the tappet located in an overhead valve engine?
However, a tappet (also known as a cam follower or lifter) is a small cylindrical mechanism which is attached to the end of the pushrod(in overhead valve engines) or the rocker arm (in overhead cam engines).
What causes a crack in the tappet valve?
This is the reason why valve adjustment should be completed when the engine is as cold as possible. On the other hand, if the tappet adjustment is too tight, the valves can stay open slightly too long, meaning much more heat is transferred through to it than it’s designed to handle which can cause chips and cracks in the valve.
What should I do if my tappety engine is not working?
If these changes make no difference to the tappet noises, a full tappet adjustment should be the next move. Using a feeler gauge to wedge between a rocker arm and the valve stem, a factory setting can be found through a workshop manual to adjust the valve adjustment screw to the correct clearance.
Where is the locking screw on a tappet engine?
A locking screw is located at the connection to the rocker arm which can increase or decrease the amount of lift that the tappet allows from the camshaft, thus making the amount of valve lift adjustable through this method.
Do you need to adjust the valve on a hydraulic lifter?
Our valves were not set correctly! The typical hydraulic lifter requires an adjustment that is roughly half the available travel of the plunger.
Do you have to adjust the valves on a Harley Davidson?
The truth is that Harley-Davidson Sportster and Big Twin Engines since the early 1980s have been built with hydraulic lifters in the valve train, which means that you never have to adjust the valves. They stay adjusted automatically.

How do you replace a fuel valve on a Harley?
Begin by draining as much fuel from the tank as possible. It is not necessary to remove the fuel tank to replace your Harley fuel valve. In fact, some tasks are easier with the tank on the motorcycle. When you can not drain anymore gas through the valve, jack the rear end of the motorcycle.

What should I do if my fuel valve is not working?
In fact, some tasks are easier with the tank on the motorcycle. When you can not drain anymore gas through the valve, jack the rear end of the motorcycle. This will allow most of the residual fuel to flow to the forward most end of the tank. Usually, away from the fuel valve. Still, always be prepared to catch residual fuel when removing the valve.
What happens when a valve is adjusted too tight?
If adjusted too tight (the plunger fully compressed) the valves stay open slightly, and do not close all the way. This removes the important cooling time (lash) that removes heat from the valve stem.
Where is the correct valve clearance on a Bentley?
Look at the rocker arm; at the very end you will see where it contacts the valve. You might also notice a small space in between these two parts. This space is what we are adjusting ( Figure 9 ). The Bentley Manual lists the correct valve clearance at 0.25mm (0.010in) with the engine cold.
What kind of expiratory valve sets do I Need?

Where do you place a valve stem on a LSX?
Once the valve stem tips and rocker arm seats are coated with assembly lube, the rocker arms can be installed on the rocker stud. Applying a generous amount of assembly lube to the rocker arm ball, position it on the rocker stud with the flat side of the trunnion facing up.
What’s the best way to adjust a valve?
Use a 17mm wrench to loosen the nut around the lash adjuster you are going to set. Use a screwdriver to set the valve lash adjuster so that the feeler gauge of your desired thickness fits into the gap between the rocker arm and the valve tip.
How to adjust valves on a 4 Cycle Motor?
My TECH for adjusting valves on ANY 4 cycle motor is to watch the valves…first the INTAKE will open/close immediately followed by the EXHAUST open/close – Continue to rotate it over a bit and you are guaranteed to be on the “heel” for both valves. Adjust and move on the the next set.
Where do you put the feeler gauge on a valve?
Get out the .022″ feeler gauge and place it between the top of the valve stem and the rocker arm tip. Snug down the rocker “just” until you begin to fell resistance. You should be sliding the feeler gauge back and forth gently on stock style slotted rocker arms, or gently side-to-side if using roller tip rockers.
If adjusted too tight (the plunger fully compressed) the valves stay open slightly, and do not close all the way. This removes the important cooling time (lash) that removes heat from the valve stem.
