Drive your Tuson upwards onto ramps or possibly lifts. You can implement a jack, but brace entry wheels so they don't really roll. Set the emergency break to be sure the car doesn't recede.

1- Drain typically the engine oil and eliminate the negative battery connection. Take out typically the timing belt along with the oil pan. Take away the oil screen, your gasket, the petroleum pressure switch, your oil filter clump and gasket.
2- Take away the plug cap in the oil pump perhaps the case with Method 09213-33000. Insert some sort of 0. 32 inch screwdriver throughout the plug hole whereas plugging the left side within the engine block. The screwdriver really should go in at a minimum 2. 4 in ..
3- Pull through the pump made gear, the left counter top balance shaft bolt and therefore the front case mounting bolts. Note the program plans and locations within the bolt. Remove the way it is and gasket and then the two counter balance shafts out of your block.
4- Separate that oil pump protect and gears with the case. Remove the screwdriver on the plug hole and eliminate the pump driven gear and then the left counter stabilize shaft bolt. Take the essential oil pumpcover belonging to the case. Install Brand new Oil Pump
5- Assemble the Water pump and Timing belt and all other assemblies you had removed earlier.
6- Fill the crankcase with the correct level. Start your Tuson engine and check out leaks.

Welcome to Fixya

Sounds like something let go, you could also have a stuck solenoid for that gear, or the clutch plates blew apart, this vehicle would need to have the computer scanned for codes to see if its a seloniod or speed sensor, if not then the trany would need to be opened and checked. This sounds like its time for a rebuild.

Thank you for using Fixya!

see diagrams from autozone.com. Cam sprocket has an "UP" label, but also 2 scribes on the sides to align to upper head surface. The critical part of the job is keeping tension on the side of the belt that is opposite from the tensioner as the tensioner is released onto the belt. The timing marks must be aligned when the job is done.


To install:

1. Install the camshaft timing sprocket so that the UP mark is up and the TDC marks are parallel to the cylinder head gasket surface. Install the key and tighten the bolt to 27 ft. lbs. (37 Nm).
2. Install the crankshaft sprocket so that the TDC mark aligns with the pointer on the oil pump. Install the spacers with their concave surfaces facing in. Install the key. If equipped, install the TDC sensor assembly back into position before installing the timing belt.
3. Install and tension the timing belt. Use a 6 x 1.0 mm x 25 mm bolt threaded through the cam belt tensioner plate to temporarily hold the tensioner.
4. Temporarily install the crankshaft pulley and rotate the crankshaft counterclockwise 5-6 turns to be sure the belt is properly seated.
5. Set the No. 1 piston at TDC for its compression stroke.

WARNING If any binding is felt when adjusting the timing belt tension by turning the crankshaft, STOP turning the engine, because the pistons may be hitting the valves.

1. Rotate the crankshaft counterclockwise so that the camshaft pulley moves only 3 teeth beyond its TDC mark.
2. Loosen, then retighten the temporary cam belt tensioner bolt.
3. If the rear balance shaft sprocket/gear case assembly was removed, perform the following:
   1. If the rear balance shaft was moved, rotate the balance shaft until the 6 x 1.0mm x 100 mm bolt can be installed into the maintenance hole to the scribed line.
   2. Align the notch of the balance shaft sprocket edge with the pointer on the gear case. Install the rear balance shaft sprocket/gear case assembly using a new O-ring coated with fresh engine oil. The balance shaft sprocket should be installed in the TDC position. The pointer on the gear should align with the pointer on the oil pump housing plate.
   3. Tighten the mounting bolts to 18 ft. lbs. (25 Nm).
   
   
4. If the front balance shaft sprocket was removed, perform the following:
   1. Install a suitable and sturdy screw driver or drift through the maintenance hole in the shaft behind the sprocket to hold the front balance shaft.
   2. Install the front balance shaft sprocket and mounting nut. Torque the nut to 22 ft. lbs. (29 Nm).
   
   
5. Make sure the balance shafts and crankshaft are in the TDC position.
6. Remove the crankshaft pulley, and if removed, install the balance shaft belt drive sprocket.
7. Install the balance shaft belt, making sure the balance shafts and sprockets are still in the TDC position.
8. If removed, install the balance shaft belt tensioner and tension the balance shaft belt.
9. Loosen, then retighten the tensioner adjusting nut to 33 ft. lbs. (45 Nm).
10. Remove the 6 x 1.0mm x 100mm rear balance shaft holding bolt.
11. Temporarily install the crankshaft pulley and rotate the crankshaft 2 revolutions counterclockwise, stopping at TDC.

WARNING If any resistance is felt, stop immediately and determine the cause.

1. Recheck that all of the TDC marks align for both the camshaft and balance shafts.
2. Loosen, then retighten the tensioner adjusting nut to 33 ft. lbs. (45 Nm).
3. Remove the 6 x 1.0 mm x 25 mm bolt used to secure the camshaft timing belt tensioner.
4. Remove the crankshaft pulley and install the lower cover.
5. Install the crankshaft pulley, lubricate the bolt threads and both sides of the crankshaft pulley bolt with fresh engine oil and tighten the crankshaft pulley bolt to 181 ft. lbs. (245 Nm). Do Not use an impact wrench.

See Figures 19 and 20

1. Install the upper timing cover and the valve cover. Be sure the seals are properly seated.
2. Install the side engine mount. Tighten the through-bolt to 47 ft. lbs. (64 Nm). Tighten the mount nut and bolt to 40 ft. lbs. (55 Nm) each.
3. Remove the floor jack.
4. Install and tension the alternator belt.
5. Install the power steering pump and tension its belt.
6. Install the splash shields.
7. Reconnect the positive and negative battery cables. Enter the radio security code.
8. Check engine operation.

8. Inspect for leaks.

take off dist cap.turn rotor one way then the other. if the tip of the rotor moves more than 1/16 of an inch of free travel then the block bushing is worn out. the block bushing is bronze and it holds the oil pump drive shaft in perfect alignment. when worn the cam and oil drive shaft get cocked causing the oil pump drive gear teeth to wear off,sometimes cam gear is also damaged but rarely.the dist. is driven off the oil pump drive shaft and when there is exessive play it causes ignition and fuel timing problems with symtoms just like yours

Did you put alot of pressure on belt when installed ? to tight will cause that vibration

yes , depending on wheter you talking about torque converter seal or rear engine main seal , on trans if your front pump bushing has excessive wear then it will not seal because the torque converter input shaft will ride on seal more than it is supposed to and also it will not run true, also check TC mounting of flex plate if you flex plate is not centered then it will rotate out of balance and cause leaks and pump damage, if you talking about a rear main engine seal you may have a issue with run out and or bearing wear issues cause seal to not be able to do its job, check all those issues, crank shaft end play as well as up and down play and check rotational run out on TC of trans and pump bushing in trans pump... hope this helps, thanks please rate...

The oil pump can be changed without pulling the engine.

The impressive looking thing is the balance shaft assembly. These counter-rotating shafts balance out the inherent vibration of the engine. You can remove it, as long as you do not disrupt the gear placements relationship to each other. The balance assembly is set to a specific point.
