Hi i mean a 520d diesel i change crankshaft pully and the car driveing slugish what i did wrong the crankshaft pully dont have a dowel or mark to fit in?need help

Clearly something has gone back together differently.

Some clutch centre plates can go in either way around and still work though there is a right and wrong way. Perhaps the release bearing or the lever or fulcrum moved during assembly.
A few well placed spots of grease during assembly helps reduce the effort of operation...

Is it possible the locating dowels for the gearbox to engine fitting are still in the scrap engine? Without the dowels to ensure the gearbox shaft aligns accurately with the centre of the crankshaft, clutch operation and other things can be compromised.
There are usually also dowels in the flywheel to locate the clutch cover/pressure plate and these sometimes become lost...

While nothing to do with your problem, if the engine crankshaft is fitted with a clutch/gearbox pilot or spigot bearing, it should be checked, lubricated or replaced before reassembly as they can cause a great deal of trouble if they fail.
Many manufacturers have deleted the bearing altogether...

if it has a vicous fan check the viscous clutch with engine not running try spinning the fan it should move easily if not viscous is stuck

Hi,just inline the crankshaft to the top dead centre marks,then check that the camshaft marks line up,if they dont line up then turn the crankshaft pully again untill the camshaft marks line up,slacken the timeing belt pully adjuster take belt off and replace with new one,tighten the pully adjuster back up,now put a spanner on the crakshaft pully and turn clockwise untill the top dead centre marks and the camshaft marks inline if they dont then slacken the ajusting pully inline marks again and try again,if marks do inline ok then you are ready to start the car.
hope this helps good luck.

Hi
Why are you removing this sprocket?
Or, do you mean crankshaft pulley?
If you are looking to removing the timing sprocket be aware that you will need to put the engine at its required timing setting points, YOU MUST USE THE CORRECT TIMING TOOLS and when tnese are fitted remove belt, remove crankshaft sprocket.
Fitting is reverse but there will be a resetting figure for the timing belt.
********Please dont do this job if you either have never dont this job before, do not have the correct tools, or just dont have the experience. Dont let a "friend do it or help you unless they are qualified Technicians.
You will destroy the engine in a few seconds of cranking if you get this wrong!! Be warned.
cheers

This is on a 3.4L V6

Disconnect battery earth lead. Do not turn crankshaft or camshaft when timing belt removed. Remove spark plugs to ease turning engine. Turn engine in normal direction of ratation unless otherwise stated, Support engine. Remove, engine mounting, auxilliaty drive belts. Water pump pulley 1. Crankshaft pulley bolts 21. crankshaft pully 2. timing belt covers 3. Turn crankshaft to TDC on No 1 cyclinder. Ensure crankshaft sprocket, camshaft sprocket, oil pump sprocket and balancer shaft sprocket timing marks aligned. Timing marks on camshaft sprockets should align with cylinder head upper face. Dowel pins on camshaft sprockets should face upwards. Slacken tensioner bolt. Move tensioner away from belt and lightly tighten bolt. Remove, automatic tensioner unit bolts. Automatic tensioner unit. Timing belt, crankshaft centre bolt, crankshaft sprocket. Crankshaft sprocket guide washer. Slacken blancer shaft belt tensioner bolt. Move tensioner away from belt and lightly tighten bolt. Remove balancer shaft belt.

Installation
Ensuring timing marks arligned. Note timing marks on camshaft sprockets should align with cylinder head upper face. Exhaust sprocket mark is on recess, but inlet sprocket mark is on tooth. Note: to check oil pump sprocket positioned correctly, removing blanking plug from cylinder block. Insert 8mm diameter Phillips srcrewdriver in hole. Ensure screwdriver is inserted 60mm from face of cylinder block. if screwdriver can only be inserted 20mm: turn oil pump sprocket 360°. Insert screwdriver again. Fit balancer shaft belt in anti-clockwise direction, starting at crankshaft sprocket. Slacken balancer shaft belt tensioner bolt. Turn tensioner clockwise to tension belt. Tighten bolt to 15-22Nm. Apply thumb pressure to belt. Belt should deflect 5-7 mm. If not repeat tensioning procedure. Install crankshaft sprocket guide washer, crnakshaft sprocket. Tighten crankshaft cente bolt. Tighten torque:110-130 Nm. Note ensure crankshaft sprocket guide washer is fitted correclty. Oil treads and contact face of crankshaft body before fitting. Check tensioner body for leakage or damage replace if necessary. Check pushrod protrusion is 12mm. If not replace automatic tensioner unit. Slowly compress pushrod into tensioner body until holes aligned. Resistance should be felt. Place flat washer under tnesioner body to avoid damage to body end plugs. Retain pushrod with suitable pin through hole in tensioner body. install automatic tensioner unit to cylinder block. Tighten bolts to 22-27Nm. Fit timing belt in anti-clockwise direction, starting at the tensioner pulley. Slacken tensioner pulley bolt. Turn tensioner pully clockwise to temporarily tension belt. Tighten bolts to 43-45Nm. Turn crankshaft slowly 1/4 turn anti-cockwise. Turn crankshaft clockwise until timing marks alligned. Slacken tensioner pully bolt. Fit tool to tensioner pulley. Tool No 09244 28100. Apply clockwise torque of 2,6-2,8 Nm to tensioner pulley. Tighten bolt to 43-45Nm. Insert special tool in timing belt rear casing. Tool no 09244-28000. Screw in tool until pin can be removed from automatic tensioner unit. Remove special tool. Tool nr 09244-28000. turn crankshaft two turns clockwise. Wait 15 minutes. Ensure timing marks aligned. Check extended length of pushrod is 3,8-4,5mm. Install components in reverse order of removal. Tighten crankshaft pulley bolts, Tighten torque 20-30Nm

If you have what you said then you have a problem as the key in the crankshaft must be a good fit, and if the woodrough key or grove in crankshaft which holds key is even slightly worn dont trying fitting another pully as the crankshaft has to be replaced first as its the key which dose the driving not the bolt
Sorry mate
Let me know how you go Ron

there is a little mark on the crankshaft which you line up with the 'o' mark on the casing ..
remove the cam cover and look at the cam you should see a nob on the cam about 3 th lob and that should be facing just left of the engine ..
if you have a turbo there is two notchs on the injection pump pully ..if turbo there is a 't' mark on the rear of the cover the notch on the pully should mark up with the 't'..
the timing is set..

hi
first remove the timing cover afer remove also remove the crankshaft pully.
now you can see timing belt clearly next remove the valve cover to see valves.
Rotate the engine by hand you can see where you remove the engine bully key grove that key should be top side while you rotating the engine there is mark like -- on the cover behand where you remove the pully so that mark and the crank shark key should in lined.
after that look the injection pump pully you can see front side mark --- look the engine direct behand the bully you can see mark that two mark should be in line have look the engine valves first cylinder should be close and the 4cylinser exhaust valve open.
i thing that will help you.

dont worry this language is my second language.if i make any mistake how i typing.
