Somewhere in the world there may be a specification for that but in reality, just make the pulley through bolt tight (without being and animal on it). The long jack bolt gets tightened first. There, you check belt deflection. You should have about one inch or slightly less deflection in the center of the longest run of the belt. After getting it to that point, lock it and tighten the pulley. Run it for a few minutes and then drive it. If the belt squeals, loosen the adjustment and give it a few more turns. Do not over-tighten it. A loose belt will be noisy. An overtightened one can destroy component bearings.

My idler pulley on my 96 ford explorer is grinding on the bracket that holds it in place and creating a loud grinding noise, what steps would I use to resolve it??


change the idler pulley . its held on by a bolt in the center of the pulley. the bearings are sealed so you can't grease them. but first you have to take the tension off the serpintine belt. that is also another pulley located below the idler.don't know what size bolt on a ford but use a long wrench grab the bolt on the tensioner push to the right like you were tightening it. that will release the tension on the belt. don't take the belt all the way off just off the idler pulley. change the pulley and do tha same to reinstall the serpintine belt. if the belt comes all thr way off under the hood or on the front around the top of the radiator there will be a schematic that shows you how the belt should go around everything. let me know what happens. sometimes the tensioner pulley will grind also so be sure your changing the right pulley

15. Install water pump pulley.
Tightening torque:9.0~12.6 lb-ft (12.3~17.2 N·m, 1.3~1.8 kg-m)
16. Install generator belt and adjust the tension.
17. Install P/S and/or A/C drive belt and adjust the tension.
18. Connect negative battery cable.

INSPECTION
Never forcefully twist, turn inside out or bend timing belt. Do not allow oil or grease to come in contact with timing belt.
1. Replace timing belt if it is contaminated with oil or grease.
2. Check timing belt for uneven wear, fraying, peeling, cracking and hardening. Replace timing belt as necessary.
3. Bend timing belt into a "U" shape as shown in figure. Distance "A" must be at least 1.0 in (25 mm).
4. Inspect both idler pulley and tensioner pulley for uneven wear and smooth bearing operation.
5. Inspect camshaft pulleys and timing belt pulley for broken teeth or damage.
Replace any component that shows damage, excessive wear, or that appears prone to a possible failure.

What is the correct tension for the serpintine belt????


The belt tensioner device places a sufficient running,or opperating tension on the one serpentine belt. While driveing all the other pulleys, under the various loads, and speed changes of driving. If the spring tension is not sufficient for the pully to grip the belt,and you can here slippage,or a squealing sound,the spring tensioner may be weak or its working or pivotting action, may be effected by a corroded or dry condition,in the pivot bolt.

Cant find drive belt tensioner bolt to loosen serpintine belt


The serpentine belt tensioner / pulley is on the front of the engine, and part of the belt 'routing'.

Its job is to put tension on the belt as it drives the other devices like the power steering pump, water pump, air conditioning compressor.

It is an aluminum casting that mounts with a single bolt to the engine. The pulley is attached to the arm.

There are a few ways to move / pry the arm inwards, thus releasing the tension on the belt for removing/installing: grab on the pulley bolt (15mm?) with a wrench, or some later models have an opening for a 3/8th socket wrench to attach to directly without a socket.

Timing belt slak


  1. Set timing belt tensioner.
(a) Using a press, slowly press in the push rod using 100 - 1000 kg (220 - 2,205 lb, 981 - 9,807 N) of pressure. (b) Align the holes of the push rod and housing, pass a 1.27 mm hexagon wrench through the holes to keep the setting position of the push rod. (c) Release the press.
  1. Install timing belt tensioner.


(a) Turn the No.1 idler pulley bolt counterclockwise to obtain the specified torque toward the left as far as the No.1 idler pulley will go, and temporarily install the tensioner with the two bolts Torque: 18 N.m (180 kgf.cm, 13 ft.lbf)


NOTICE: To apply the correct torque, apply the torque wrench along the axis through the bolts of the No.1 idler pulley and exhaust camshaft timing pulley.


(b) Slowly turn the crankshaft pulley 5/6 revolution, and align its groove with the ATDC 60° mark of the No.1 timing belt cover.
NOTICE: Always turn the crankshaft clockwise.





(c) Insert a 1.90 mm (0.075 in.) feeler gauge between the tensioner body and No.1 idler pulley stopper.
(d) Turn the No.1 idler pulley bolt counterclockwise to obtain the specified torque.
Torque: 18 N.m (180 kgf.cm, 13 ft.lbf)
NOTICE: To apply the correct torque, apply the torque wrench along the axis through the bolts of the No.1 idler pulley and exhaust camshaft timing pulley.

(e) While pushing the tensioner, alternately tighten the two bolts. Torque: 21 N.m (210 kgf.cm, 15 ft.lbf)



(f) Remove the 1.90 mm (0.075 in.) feeler gauge. (g) Remove the 1.27 mm hexagon wrench from the tensioner.


(h) Slowly turn the crankshaft pulley one revolution, and align its groove with theATDC 60° mark of the No.1 timing belt cover.
NOTICE: Always turn the crankshaft clockwise.




(i) Using a feeler gauge, check the specified clearance between the tensioner body and No.1 idler pulley stopper. If the clearance is not as specified, remove the tensioner and reinstall it.
Clearance: 1.80-2.20 mm (0.071 - 0.087 in.)
  1. Check valve timing.



(a) Slowly turn the crankshaft pulley two revolutions from TDC to TDC. NOTICE: Always turn the crankshaft clockwise.




(b) Check that each pulley aligns with the timing marks as shown in the illustration. If the marks do not align, remove the timing belt and reinstall it.

How do I tighten the power steering belt on my 2002 xl-7?


1)To adjust P/S belt tension, loosen tension pulley bolts and turn tension pulley using hexagon wrench. 2)Adjust belt tension to specification described in CHECK. Then tighten tension pulley bolts to specified torque. Tightening torque P/S belt tension pulley bolt (a): 25 N·m (2.5 kg-m, 18.5 lbf-ft) Deflection of P/S belt 4 – 7mm (0.16 – 0.28 in.) measured from the center of the belt between the top and bottom pulley on the right hand side if you have airconditioning, or between the crank and the ps pulley if you don't have AC
