1986 yamaha radian yx600 Inline 4 Cylinder what is the firing order


there is nothing on the net so you have 2 options
call a yamaha service center or pull the rocker covers off and check the position of the rockers
when no 1 is on compression the valves will have max valve clearance so that is no 1 position
the firing order will be either 1,3,4,2 or 1,4 2,3 so the next piston to fire will be the next piston to get max valve clearance and so on
lot easier to just call a service dealer

What is the clearance between the rocker arm and the valve spring in a GM 2.2L motor


there is no specification for what you want
the valve clearance is between the end of the rocker arm and the end if the valve stem
the stem end is proud of the spring retainer so if your rocker arm is touching the spring retainer , you have a big problem as for the procedure it is set out in the workshop manual but if you don't have a manual it can be done like this
you will need the firing order of the engine first
now adjust no 1 piston valves when the next piston to fire has the valves in the rock position
that is the exhaust valve just closing as the inlet is just opening a bit of movement of the crank makes either valve move up or down
adjust no 1 piston valves
now move on to the next piston to fire and adjust the valves that were rocking
follow that procedure until all the valves are adjusted
for example
on a 4 cylinder engine with a firing order of 1--3--4--2
bring up no 1 piston and adjust the valves when the valves on no 3 piston are rocking
next piston to fire is no 4 so adjust no 2 piston valves
next piston to fire is no 2 so adjust the valves when no 1 valves are rocking
the procedure is the same for engines with any number of cylinders

Setting valve clearances


360 with hydraulic lifters, the crankshaft wit a ratchet and socket to get each valve closed. When lifter is at bottom turn the valve adjuster out to where you have free movement then turn adjuster till the rocker arm touches the lifter, then turn the adjuster in three quarters of a turn, and that valve is adjusted. No other clearance is required on hydraulic lifters. Do this with each valve in turn as each piston comes to top dead center using the firing order as a guide. When #1 piston is up to top dead center, both valves are closed. Adjust intake and exhaust at this time. Then the next in the firing order. The firing order can be found on the intake as is each cylinder marked with it's number. If it were a Chevy small block, for example only, firing order is 1-8-4-3-6-5-7-2. I would bring # 1 cylinder up to top dead center on compression stroke by removing that spark plug and stick my finger in the hole and crank the engine till I felt my finger being pushed away with compression, then bring that piston up till the timing mark was on the "0" of the timing tab at drivers side of the harmonic balancer on the crank. Adjust both valves on #1 cylinder and then turn the crank until both valves of #8 cylinder were free moving at the rocker. Then to the next in order of fire. I would turn each adjuster out at least one full turn before starting this procedure, then adjust them in order of firing starting with #1. It isn't hard, just takes time to do it right.

Adjusting tappet clearance


If you have adjustable tappets bring the engine to top dead center no 1 piston firing The rocker will be on the back of the cam lobes. Inlet .010" hot exhaust .012" hot and then turn until next firing piston is in position. Go by firing order. I suspect that a 1997 model would have hydraulic adjusted tappets which means no manual adjustment. If it is rattlly I would be checking for worn rocker shaft and rocker bushes.

I need the required valve & inyector clearance on a M11 engine


Cummins M11

Intake valve clearance 0.010 inch
Exhaust valve clearance 0.024 inch

The firing order is 1-5-3-6-2-4 and that is the order the valves should be adjusted started with first timing mark on main pulley adjust cylinder number 1 The valves and injector should be adjusted at the same time The crankshaft is then rotated 120 degrees to next timing mark and cylinder 5 is adjusted, the crank is rotated again 120 degrees to next timing mark and cylinder 3 is adjusted.then back to the first timing mark, cylinder 6 is adjusted, etc/

Adjusting nut on plunger should be adjusted to the point where you feel the plunger just reaches the bottom.of travel/bottoms out.

Trying to set the intake and exhaust valves on a 2001 dodge dakota v6 what does the gap need to be and i also need to know the firing order


Your engine uses hydraulic lifters and the clearance is not adjustable. Just make sure to tighen the rockers to 21 Ft/Lbs.

Firing order is 1-6-5-4-3-2..Cylinders 1-3-5 are on the DRIVERS side Front to back and 2-4-6 are on the PASSENGER side Front to back.

How do you adjust aftermarket roller rocker arms


well first you need to know the firing order...if it's a small block chevy the firing order is 18436572. You need to write the second four digits underneath the first four digits.

so it looks like this 1843
6572

This will let you know which rocker to adjust...turn the engine over by hand using a rachet on the crank shaft bolt by the harmonic balancer until you get both rockers for number 6 cylinder moving at the same time. Now you may adjust the clearance for both rocker for number 1 cylinder. Then crank the engine over by hand again until number 5 cylinder rockers start to move. Now you can adjust the clearance on number 8 cylinder. You will need to know the manufacturer specs for the valve clearance...continue until all rockers have been adjusted.

Note: The engine should be warm when you make the adjustment.

please rate this.
