I removed the upper timing belt cover with no problem. But there is no clearance for the lower cover to move up far enought to clear the main dirve pulley at the bottom. The top of the cover bumps against the water pump. It's just stuck there.
I don't want to have remove the main drive shaft to get the lower cover off.
No one listened to the question. I have the identical situation. I can't get the bottom half of the timing belt cover off in order to replace the water pump. I wish some one would answer the actual question above.

CAUTION:When aligning crankshaft and camshaft timing marks always rotate engine from crankshaft. Camshaft should not be rotated after timing belt is removed. Damage to valve components may occur. Always align timing marks before removing timing belt.
Before the removal of the timing belt, rotate crankshaft until the TDC mark on oil pump housing aligns with the TDC mark on crankshaft sprocket (trailing edge of sprocket tooth)
NOTE:The crankshaft sprocket TDC mark is located on the trailing edge of the sprocket tooth. Failure to align trailing edge of sprocket tooth to TDC mark on oil pump housing will cause the camshaft timing marks to be misaligned.
Install 6 mm Allen wrench into belt tensioner. Before rotating the tensioner, insert the long end of a 1/8” or 3 mm Allen wrench into the pin hole on the front of the tensioner .
While rotating the tensioner counterclockwise, push in lightly on the 1/8” or 3 mm Allen wrench, until it slides into the locking hole.
Remove timing belt. CAUTION:If timing belt was damaged due to incorrect tracking (alignment), the belt tensioner assembly must be replaced
Set crankshaft sprocket to TDC by aligning the sprocket with the arrow on the oil pump housing.

Replacement of the timing belt on B230F engines is fairly straightforward. Note that you will need the proper tool to secure the crankshaft sprocket during removal procedures. Obtain the timing belt tensioner as well; it is designed to last only as long as the timing belt. Begin by cleaning the area around the timing belt upper cover. Remove the upper cover. Remove the drivebelts on all accessory components. Remove the fan (if you have a mechanical fan). Carefully leverage it out of the shroud. It may be necessary to remove the shroud as well - two 7mm bolts secure it to the radiator. Remove the lower bellhousing cover at the rear of the engine. Turn the crankshaft to bring the engine to Number 1 cylinder, TDC, firing. The timing marks will align when this is done. Remove the crankshaft sprocket bolt. It may be very tight, and clearance is quite limited. Take care not to move the crankshaft from its set position. Inspect all front oil seals before continuing, along with the water pump condition. If anti-boil weeps from the weep hole on top, you must replace the water pump or else it will contaminate the new belt. Lock the timing belt tensioner in position. This can be done with a small nail, bringing it back and out of the way. Remove the timing belt. Replace all oil seals that leak, are weak or missing. Oil will ruin the new timing belt. Installation is essentially a reversal of removal, after the tensioner is replaced and unlocked, spin the crankshaft sprocket two complete turns, noting if the timing is correct by way of the pointers aligning with the marks in the rear timing cover. Push down on the belt to ensure it seats correctly. Tighten the tensioner to the specified torque. Install the cover, rear bellhousing cover (if removal was necessary) and nuts. Screw the backplate onto the front timing cover. Install the fan and fan shroud. Refill the coolant if the water pump was changed. After double-checking installation items, road test the vehicle after allowing it to warm up to check for coolant or oil leakage. After 600 miles, remove the rubber plug at the front of the timing cover. Loosen and tighten the tensioner bolt. Place your labels indicating mileage and date of timing belt drive maintenance at the front of the engine.
Timing belt removed, static timing was not set before removing timing belt.
[Set Static Timing: No.1 piston is brought up to TDC before removing timing belt.
Cam gear has a punchmark on face of gear, and this mark aligns with one single tooth. There is a matching punchmark on the Timing Belt Rear Upper Cover.
Facing the cam gear, the mark is to the upper right. There is an 'egg shape' of the timing belt upper rear cover, in this spot. This punchmark is in that 'egg shape', and is close to a bolt hole. The cam gear mark lines up with the Timing Belt Rear Upper Cover, mark.
The crankshaft gear has a punchmark on the face. It lines up with one single tooth. There is a corresponding punchmark on the lower right side. An alignment mark)
Should be a round punchmark on the face of the crankshaft gear. It lines up with a single tooth. Wipe the gear clean, use a little carb cleaner. (NO flames, or sparks nearby, well ventilated area)
Barring you cannot find the crankshaft mark, find the camshaft alignment marks, make sure they are aligned with the alignment, (Punchmark), on the Timing Upper Rear Cover.
Count the teeth in the timing belt. There should be 133 teeth on the belt.
There is 43 teeth in-between the timing mark of the camshaft, and the timing mark on the crankshaft.
(43 teeth in-between the Right Side Camshaft mark to crankshaft mark, 43 teeth in-between the Left Side Camshaft mark to crankshaft mark)
There should be 40 teeth in-between the two cam gears.
Before servicing the vehicle, refer to the Precautions Section.
Disconnect the negative battery cable.
Remove the air cleaner assembly and intake air duct.
Remove the upper fan shroud from the radiator.
Remove the 4 nuts retaining the cooling fan assembly. Remove the cooling fan from the fan pulley.
Loosen and remove the drive belts.
Remove the upper timing belt covers.
Remove the fan pulley assembly.
Rotate the crankshaft to align the camshaft timing marks with the pointer dots on the back covers. Verify that the pointer on the crankshaft aligns with the mark on the lower timing cover.
When the timing marks are aligned, the No. 2 piston is at Top Dead Center (TDC) compression.
Align the camshaft and crankshaft sprockets with their alignment marks before removing the timing belt. Failure to align the belt and sprocket marks may result in valve damage.
Use tool No. J-8614-01, or a suitable pulley holding tool to remove the crankshaft pulley center bolt. Remove the crankshaft pulley.
If present, disconnect the 2 oil cooler hose bracket bolts on the timing cover. Move the oil cooler hoses and bracket off of the lower timing cover.
Remove the lower timing belt cover.
Remove the pusher assembly (tensioner) from below the belt tensioner pulley. The pusher rod must always face upward to prevent oil leakage. Depress the pusher rod, and insert a wire pin into the hole to keep the pusher rod retracted.
Remove the timing belt.
Inspect the water pump and replace it if there is any doubt about its condition.
Repair any oil or coolant leaks before installing a new timing belt. If the timing belt has been contaminated with oil or coolant, or is damaged, it must be replaced.
