Timing Belt replacement for a Craftsman air compressor

To install:

1. Install the oil pump drive gear and tighten the 16 ft. lbs. (22 Nm).
2. Using a suitable seal installer, install a new crankshaft timing gear seal. Install the gear.
3. Temporarily install the idler pulley and tension spring.
4. If using the old belt, check the rotation direction chalk mark placed on the timing belt during disassembly.
5. Install the timing belt on the crankshaft pulley.
6. Install the lower timing belt cover, air conditioning idler pulley bracket, compressor bracket and the lower timing belt cover retaining bolts and nuts. Install the pollution system air pipe assembly.
7. Install the crankshaft pulley and pulley retaining bolt and torque to specification.
8. Turn the crankshaft pulley and align its groove with the 0 mark on the lower timing belt cover.
9. Install the camshaft timing pulleys and timing belt as follows:
   1. Turn the crankshaft pulley and align its groove with the 0 mark on the No. 1 timing belt cover. If the engine has not been disturbed, the engine should still be in this position.
   2. Align the alignment marks on the camshaft timing pulleys and the No. 2 timing belt cover. Install the timing pulley.
   3. Install the straight pin into the hole.
   4. When replacing the camshaft or the camshaft timing pulley. Always align the center holes of the camshaft and timing pulleys and insert the straight pin. When reusing the camshaft or camshaft timing pulleys, check that the straight pin hole position is in the same position it was at disassembly, insert the straight pin. Install the plate washer and pulley bolt.
   5. Using a suitable camshaft pulley holding tool, hold the pulley and tighten the pulley bolts to 36 ft. lbs. (49 Nm).
   6. Check that the matchmarks on the camshaft timing pulley are aligned with those on the No. 2 timing belt cover.
   7. Install the timing belt to the intake camshaft timing pulley, the exhaust camshaft timing pulley and the idler pulley.
   8. Loosen the idler pulley mount bolt until the pulley is moved slightly by the spring tension. Tighten the idler pulley mount bolt to 36 ft. lbs. (49 Nm).
   9. Check that the timing belt tension is equal all the way through. Turn the crankshaft pulley 2 revolutions clockwise from TDC to TDC.
   10. Check that the alignment marks on the camshaft timing pulleys are aligned with those on the No. 2 timing belt cover.
   11. If the marks do not align, remove the belt and install it again.
   12. Install the No. 3 timing cover gasket, cover and retaining bolts.
   13. Install the power steering pump belt.
   14. Install the four bolts, fan clutch, water pump pulley and fan shroud.
   15. Install the fan shroud mounting nuts.
   16. Tighten the fan belt adjusting bolt and nut of the power steering pump.
   17. Install the 4 bolts to the fluid coupling (fan clutch) flange.
10. Install the air conditioning drive belt.
11. Install the thermostat and water outlet along with it retaining bolts.
12. Install the spark plugs and spark plug wires.
13. Install the radiator assembly along with the radiator hoses.
14. Install the drive belts and adjust as necessary.
15. Install the air cleaner case assembly with the air intake connector.
16. Refill the coolant system.
17. Reconnect the negative battery cable. Connect a timing light and tachometer.
18. Start the engine and set the ignition timing. Recheck the idle speed adjustment. Check for leaks and add coolant as necessary.

All Mitsubishi cars pretty much hide the water pump under the timing belt. You should buy all new belts for the car and if you have 150,000+ miles consider replacing the water pump at the same time.
You will have to take off the power steering belt . First , take off the negative battery cable so you do not blow an expensive fuse on the positive battery cable clamp. Facing the back of the car , reach UNDER the alternator and loosen the bolt on the bottom right side, now loosen the bolt on the adjuster block on top, you can now turn the adjuster bolt and move the alternator to change the belt.
To take off the steering pump belt on the front of the motor, you need to loosen the nut on the back side of the pulley it holds the adjuster pulley in place . With the adjuster pulley loose , you can use the adjuster bolt to move the pulley to adjust the steering pump belt.
Now take off the upper belt cover, support the motor, take off the motor mount, jack up the right front corner of the car, take off the front right tire, take off the engine plastic under cover.
Line up the TDC timing mark on the cover to the mark on the pulley, check that the dot on the cam lines up with the timing arrow on the head, take off the lower pulleys, take off the lower engine cover, observe the timing marks/arrows and highlight with paint (crank marks and cam marks should all line up if not , put the lower cover and pulley back on and rotate the crankshaft one full turn.), loosen the timing belt tensioner pulley ,take off the timing belt, counter balancer belt if there is one. Now you can unbolt the water pump, scrape the gasket, and replace it.
The good news is, if you have tools,a compressor, an air gun (for lower pulley bolt), patience , and four to eight hours to kill, you can actually save money and do it your self.

hi mate if the pump is connected then it doesnt have a belt its direct drive and if the motor is seperate from the pump unit then it belt driven i dont understand as the picture is a direct drive (no belt)

It is reverse thread, if you have a small torch heat it up to where it's warm tothe touch then tap it with a ball peen hammer to oosen it up then try it. let me know if this helps and thanks for Using fix-ya.

3.0l Mitsubishi 6 cylinder.
support engine... remove engine mount... remove alternator, power stearing pump, compressor (if equipt) do not remove hoses from power stearing pump or compressor move them out of the way were they wont get damaged. Remove the tension pulley for the serpentine belt, and the tensioner for the compressor belt if equipt. then remove the compressor mounting bracket. Next remove the engine mounting plate and the crank pulley and balancer assembly. you should now be able to remove the the 3 piece timing cover. Once removed remove the tensioner spring from the water pump and loosen the tensioner nut. Remove the belt. At this point it is also recommended to replace the water pump and plumbing as well. The water pump service life is aproximately the same as the timing belt at 60,000 miles. This engine in stock form is a non interfering type engine. Meaning that moving the cams or crank out of sync will not cause damage. Turn each of the cams over by hand and line them up with the timing mark on the top of the back cover with the marks on the pulleys. Using a wrench turn the crank so that the pulley mark lines up with the mark cast into the block. replace the belt, tensioner spring (replace tensioner if warn) and tighten the tensioner bolt. roll the crank over 2 complete turns forward and recheck the cams to make sure the marks are still lined up. roll the crank backwards and recheck the timing marks again. (this process is much easier done with the plugs removed.) If everything is still lined up correctly (crank at TDC and cam pulleys pointing to each designated mark on the covers.) reassemble the cover and assessorys in the reverse order that they were removed and reinstall the old motor mount or replace if needed.
