Hi there, you should screw the nut all the way down and then screw the second nut down to meet. These are only there to stop piston coming out when under pressure. The piston shaft is designed so that it will not go down far enough to push the shower plate out so you don't have to worry about this. I am domestic coffee machine engineer and we are leading UK service and repair agents for La Pavoni. Any problems please get in touch with David at coffeeservice@live.com

Hi,
Use (2). And you could back it off by 1/4 turn, rather than 1/2 turn I think. You want the piston to almost touch the screen at the bottom of its travel. You don't want the piston to push the screen out.

Key is stuck in the ignition,how do i remove the ignition and put in new one,or is there a way to get the key out.


Hi, removing the barrel requires removal of the steering wheel, lockplate, and turn signal switch. Once all of these are out, you will see the screw that holds the lock in. You will need a puller to remove the steering wheel and a lockplate compression tool to push the lockplate down while removing the lockplate clip. You may be able to borrow these tools from Autozone or another tool rental outlet. I have pasted the procedure below from autozone.com. Please let me know if you have more questions, and thanks for using FixYa.

A headset wire stuck (wound) in crack of steering column in 1998 Contour. How do we retrieve it? Can the wheel be dismantled?


Yes - the steering wheel can be removed, just be prepared for the wire to be smashed or mangles and unusable. Look on the back side of the steering wheel - you will see some small holes for the retaining screws for the center piece of the steering wheel. If your model has an airbag in the wheel you will need to disconnect the battery to prevent activating the airbag.Remove the panel below the steering wheel to access the harness for the airbag and unplug. Now remove those retaining screws and the center piece of the wheel. Now you will see a large nut on the center shaft of the column.Before you remove the center nut, look at how many threads are exposed above the nut before removing. Lock the steering wheel and remove that nut. Now you will need a steering wheel puller. Find the fasteners that fit your wheel and mount the puller, Turn the puller shaft 3 turns and try to remove wire - if it won't come out then you'll need to completely remove the wheel to extract the wire. Place the wheel back on the column shaft and use that center nut to re - install the steering wheel. You may need to place that nut socket over the shaft around the threaded part and tap lightly to seat the wheel far enough to use the nut to seat the wheel back down. Press steering wheel until it sits where it did in the beginning. Re - install center piece, plug in airbag and replace that lower panel. Your local auto parts store may have a steering wheel puller for rent - if not, they are not expensive to buy ( should be less than $10.00 USD).
Hope this helps!!

LH guide is straight RHguide is curved has 3=8 slot on top to adjust has springloaded =hydralicassistfd tensioner below RH there is no adjusting screw and you cant get to anything whenfront cover is...


To install:

CAUTION Before installing the timing belt, confirm that the No. 1 cylinder is set at the TDC of the compression stroke.
  1. Remove both cylinder head covers and loosen all rocker arm shaft retaining bolts.
The rocker arm shaft bolts MUST be loosened so that the correct belt tension can be obtained.
  1. Install the tensioner and the return spring. Using a hexagon wrench, turn the tensioner clockwise and temporarily tighten the lock-nut.
  2. Make sure that the timing belt is clean and free from oil or water.
When installing the timing belt align the white lines on the belt with the punchmarks on the camshaft and crankshaft sprockets. Have the arrow on the timing belt pointing toward the front belt covers.

A good way (although rather tedious!) to check for proper timing belt installation is to count the number of belt teeth between the timing marks. There are 133 teeth on the belt; there should be 40 teeth between the timing marks on the left and right side camshaft sprockets, and 43 teeth between the timing marks on the left side camshaft sprocket and the crankshaft sprocket.

  1. 1986-87 Engines:
    1. Using a hexagon wrench, loosen the tensioner lock bolt, set the tensioner and then slowly turn the tensioner clockwise and counterclockwise 2-3 times.If the coarse tensioner stud has been removed, be sure to apply locking sealer to the threads before installing it.
    2. Tighten the tensioner lock-nut to 32-43 ft. lbs. (43-58 Nm). Tighten the rocker arm shaft retaining bolts (in 2-3 stages) to 13-16 ft. lbs. (18-22 Nm).Before tightening, be sure to set the camshaft lobe at the position where the lobe is not lifted.
    3. Install the upper and lower timing belt covers.

  2. 1988 Engines:
    1. While keeping the tensioner steady, loosen the lock-nut with a hexagon wrench.
    2. Turn the tension approximately 70-80 degrees clockwise with the wrench and then tighten the lock-nut.
    3. Turn the crankshaft in a clockwise direction several times and then slowly set the No. 1 piston to TDC of the compression stroke.
    4. Apply 22 lbs. of pressure (push it in!) to the center span of the timing belt between the right side camshaft sprocket and the tensioner pulley and then loosen the tensioner lock-nut.
    5. Using a 0.0138 in. (0.35mm) feeler gauge (the actual width of the blade must be 1 / 2 in. thick!) positioned as shown in the illustration, turn the crankshaft clockwise ( slowly! ). The timing belt should move approximately 2 1 / 2 teeth. Tighten the tensioner lock-nut, turn the crankshaft slightly and remove the feeler gauge.
    6. Slowly rotate the crankshaft clockwise several more times and then set the No. 1 piston to TDC of the compression stroke.
    7. Install the upper and lower timing belt covers.

How to replace rear shocks on 96 bmw 328i


Inside the car carefully pry up the speaker covers off the rear parcel shelf and undo the two screws that secure the speaker assembly onto the shelf. Release the clip and carefully from inside the boot pull the speakers away and disconnect the speaker connections
Open the boot and remove the carpet from the rear "wall" by unscrewing the 4 retaining "nuts" at first by hand and then using a phillips screwdriver.
bootcarpet.jpg

Lift this out and lift out the floor carpet. Carefully pull the side carpets away from the boot interior. They are held in 3 places : on one of the retaining bolts by the rear carpet, by a metal ledge at the top near the rear lights and by the ledges on the plastic parts in the boot.

Jack up the car and chock the front wheels so it can't roll anywhere. Also put something underneath the wheels so they cannot drop down when you undo the shock mounts.
reartower.jpg
Using a 13mm socket undo the two top shock mounts ONLY once you have supported the wheels so that you dont put stress on the suspension arms. Pry off the rubber dust cover.
shocklwrbolt.jpg
Undo the lower shock retaining bolt and carefully lift the entire shock away from the car.
oldcompleteshock.jpg
The old knackered shock and shock mount!
undotopmount.jpg
You need to recover the lower cup, upper cup and bump-stop from the old shock. To do this you need to remove the top mount from the old shock. If you look at the top of the piston it has a flat section to it. Get a set of mole grips and clamp them onto the flat section, do this as tight as you can so that you dont round it and using and adjustable spanner undo the piston retaining nut whilst holding the piston shaft using the molegrips.
keepthesebits.jpg
You need to recover 3 pieces from the piston shaft. 1- the bump stop, 2 - lower cup, 3 upper cup. Using the new shock mount as a template cut out a gasket from cardboard (the box the mount came in is ideal) to go between the upper shock mount and the suspension tower. Incidently according to the haynes manual this is made of rubber but mine was made of card! under no circumstances put the upper shock mount directly into the suspension tower.
newshock2.jpg
Put the 3 pieces onto the new shock and tighten the piston nut to secure the shock mount and put your new gasket onto the upper mount.
reartowernoshock.jpg
Use the opportunity to clean the suspension turret - do the top and the underneath making sure it's all clean and dry.
Put the new complete assembled shock into the suspension tower and either get someone to do up the top bolts a few turns or rest the bottom of the shock in the inner circumference of the wheel and lift it into position by lifting it up using the piston nut and then do the bolts up a few turns.
Bolt the bottom shock bolts back into place after putting some nut-lock on the threads and tighten them up securely, then tighten up the top mount securing bolts and put on the rubber dust cap.
bootcarpet.jpg
Put the side carpets back in making sure the speaker cables aren't trapped behind, putting in the end nearest the tail lights first making sure it's behind the retaining ledge both at the top and the end. Then do the centre section and finally over the bolt at the rear of the boot. Put the rear carpet back in and do up the retaining nuts. Reconnect the speakers and engage the lip and push the speaker up until the clip clips into place and do up the securing screws and clip the speaker cover back on.

Adding pressure gauge to Pavoni Europiccola


  1. in the boiler water is heated and presured up to 1.5 bar
  2. when water gets in lever and non return valve closes becouse you press the lever down, your energy is used to get high pressure, it should be frpm 7 up to 9 bar.
  3. SOLUTION==if you search way for modifying, you must consider that you must pump directly to group, not to boiler. in this case water will be cold (becouse comes from pump). you will need boiler in boiler to heat the water wich comes from pump before it gets to group. this is bit more complicated than you thought may bee but it is only solution.
