Broken Tensioner i have a broken belt tensioner for a 14 s Sulffock punch cylinder mower. The repairer says he cannot find the correct part. Can you help..

Cathy, there is a way to adjust belt tension on some models whether it is by the cable or a slotted bracket where the idler wheel is mounted, depends on make and model. If you have your manual check in it for belt adjustment. Could be stretched belt, stretched cable, worn/oil on pulley, seized tensioner, stretched/broken spring on tensioner,etc.

1. Loosen the timing belt idler pulley bolt. Using a hexagon wrench, rotate the idler pulley to release it's tension and remove the timing belt.
   

Fig. 2: After the timing marks are lined up, loosen the tensioner and remove the belt

Be careful not to bend the new belt installing it. Timing belts are designed to flex only the way they turn around the pulleys.
To install:
After removing timing belt, do not rotate crankshaft and camshaft separately, because valves will hit piston heads.

1. Confirm that No. 1 cylinder is at TDC on its compression stroke. Install tensioner and tensioner spring. If stud is removed apply locking sealant to threads before installing.
   

Fig. 3: Make sure the aligning marks are correct before installing the timing belt onto the sprockets

1. Swing tensioner fully clockwise with hexagon wrench and temporarily tighten locknut.
   

Fig. 4: The tensioner uses a spring to aid in tensioning the timing belt. Be sure to use locking sealant when replacing the stud.

1. Set timing belt, align the arrow on the timing belt forward. Align the white lines on the timing belt with the punch marks on all 3 pulleys.
   

There are 133 total timing belt teeth. If timing belt is installed correctly there will be 40 teeth between left and right camshaft sprocket timing marks. There will be 43 teeth between left camshaft sprocket and crankshaft sprocket timing marks

Jim, Double check to make sure you have correct belt for the deck and are installing it in the correct configuration as per manual or drawing on deck. Very few lawn tractors have deck belt adjustment, most do not, most deck belts have a spring loaded tensioner to take up the slack.
This could be some of your problem, the tensioner/idler pulley sometimes seize up and must be lubed up till they move freely, or your belt could be loose. Look in your manual or try google searching your make, model #, deck belt adjustment.

Well firstly if your wife drove the car for 5 miles with the tensioner broken, then the belt being lose will have slipped a couple of teeth. Did you set the camshaft and crank alignment marks correctly before you fitted the new tensioner? If you did and it still won't start then that means that you have one or two bent valve's in the cylinder head.You will have to remove the cylinder head and replace those valves or that car will never start again.

Hi Rockzone, Set the the engine to Top Dead Center before removing the old belt. If you've already removed it with the timing in any other position, do the following:- Rotate the camshaft so that the drill hole through the gear, is opposite a punch match mark behind it. (The punch mark is on the front of the camshaft cap). It is advisable to use a bright light and a mirror, which you hold at an angle in front of the camshaft drive gear. Shine the light between the gear and the cylinder head. Rotate the cam until the hole aligns with the punch mark. Once aligned, then rotate the crankshaft until the 'V' cut out on the crankshaft gear aligns with the match mark arrow on the front of the oil pump housing. Make sure that the tensioner bearing is at the maximum loose setting, fit the belt. Gently release the tensioner bearing and then recheck the timing. ( Adjust if required). When correct, tighten the lock nut on the tensioner bearing. Rotate the engine, turning it with a socket spanner from the crank shaft two full revolutions, and then recheck mark alignment. When the marks align after rotation, fit back everything else. Regards Johngee10

NOTE
When installing the camshaft sprockets, fasten them tightly while holding the hexagonal part of the camshaft.
Before installing the timing belt, if the timing marks of the cam sprocket and the cylinder head cover do not coincide, do not rotate the cam sprocket more than 3 teeth in either direction.
Rotating the sprocket more than 3 teeth may allow the valve and piston to touch each other.
If the cam sprocket is rotated more than 3 teeth unavoidably, rotate the crankshaft counter - clock wise a bit before rotating the cam sprocket.
Install the auto tensioner to the front case.
NOTE
At this time auto tensioner's set pin should be compressed and secured with set pin.




Align the timing marks of each sprocket and install the timing belt in the following order. Crankshaft sprocket--> Idler pulley--> camshaft sprocket (LH side)--> Water pump pulley--> camshaft sprocket (RH side)--> Tensioner pulley.
NOTE
In this step, No. 1 cylinder is in the TDC (Compression stroke).
Be very careful if you use your fingers.
