I am replaceing my crank pulley/harmonic balancer pulley on my 2003 mini cooper s. i am wondering how to set the timing on the crank pulley at top dead center? Is there such a thing in this car?

Here is a post with the torque specs. https://www.taurusclub.com/forum/82-maintenance-repair/254498-need-torque-specs-harmonic-balancer.html

harmonic balancers by design have a rubber insertion between the hub and the pulley
that rubber breaks and relies soley on friction to drive the pulley
it the tdc mark and the piston position are not correct , that would indicate that the harmonic balancer needs replacing
however when replacing the belts always go of the timing marks on the pulleys on the crank and cam shafts and not off the balancer

i dont think is your harmonic balancer that dont make any sound check all the pulleys cose to change the harmonic ba... you havto remove and change your crank pulley along with it

need a harmonic balancer pulley you can rent them at your local auto part store

the garage may have did something to the crank position sensor that is located behind the harmonic balance. there is a ring gear there to for the timing

how can i set a toyota 1rz engine on timing

The fan clutch is connected to the water pump. The harmonic balancer is the crank pulley. If the fan clutch/pulley the fan clutch is attached to is sloppy than the water pump is bad.

The harmonic balancer is integrated with the crankshaft pulley, and if replaced requires taking the bolt out from the side of the 4 cyl. engine.

I would recommend that an experience engine rebuilder perform the service.

Inspect the Harmonic Balancer:

The harmonic balancer (vibration damper) is inspected for signs of wear in its center bore.

• Also inspect the rubber mounting for indications of twisting and deterioration.
• The outer ring can slip, causing an out of balance condition. Replace any harmonic balancer that has slipped.
• With the cylinder head removed and the piston at top dead center (TDC), make a visual comparison. Do the timing marks for TDC on the timing cover and damper appear to be accurate.
• Be sure the damper is the correct one for the vehicle. The wrong one can be worse than none at all.
• Sometimes a damper can become loose on the crank. Check the keyway for wear that can result from improper damper installation, the wrong size key, or a loose damper hub to crank fit.
• Be sure all pulleys are straight. A damaged pulley can force a crankshaft to bend during engine operation.

This is a general guide on replacing the harmonic balancer, but there are other instructions that the rebuilder would follow to actually do the service for you:

To remove the harmonic balancer, the cylinder head and timing cover must be removed and the piston should be at top dead center (TDC).

• Install the vibration damper by pounding it on, or use a special installation tool.
• Generally, the damper is installed unit it bottoms out against the oil slinger and the timing sprocket.
• If in doubt, install the water pump and pulley, and then pound the damper into place until its pulley aligns with the water pump pulley.
• It is advisable to use the installation tool, because pounding on the damper can cause stress on the crank thrust bearing surface.
• It is best to stand the engine block on end and support the crankshaft if the damper must be pounded on.
• Some vibration dampers are not pressed-fit on the crankshaft.
• Be sure to install a large washer behind the damper retaining bolt on these engines; otherwise, the damper might fly off, causing damage and a safety hazard.

Remove yonder pulley and you will find the bolt holes are elongated. get another from a scrapyard (take the bolts too.) replace and you should be fine.

inspect the harmonic balancer.
When the crank turns there is a rubber buffer between the pully and crank portions of the balancer that could have let go causing an engine knock like noise.
