Does the pulley to the gearbox need to not slip on the shaft? Does the set screw need to be tightened if this is happening?

There is a set screw somewhere on/in the pulley. Find it and try to tighten it. It MAY not be a conventional screw.

There should be a set screw on the pulley that tightens the pulley to the drive shaft. It needs tightening.

To remove or install a belt on the Ilco 008, the shaft must be slid out of at least one bearing. If there is a guard cover over the pulley, remove it. Loosen the setscrew(s) on the cutter shaft pulley, and slide the shaft to the left. Mine is an older model, with no guard and the belt can be changed without removing the shaft completely.
After putting a new belt around the pulley, slide the shaft back into the right-hand bearing.
Be sure the pulley set screws are aligned with the flats on the shaft and that there is minimal end play and the cutter turns freely. Tighten the set screws and stretch the belt over the motor pulley.

Timing belt set-up for a 2000 Seat Inca 1.9 SDi

1. Align the crankshaft timing marks on the flywheel / gearbox


2. Remove the valve cover
3. Lock the camshaft


4. Fit the injection pump locking pin



5. Loosen the camshaft gearwheel bolt, 180 degrees. Use a wrench to counter-hold
6. Loosen the camshaft gearwheel while holding it in place



7. Fit the timing belt in the sequence as shown in the below figure: a - b - c - d - e - f - g



8. Fit the timing belt and camshaft gearwheel together
9. Turn the tensioner clockwise to align both marks



10. Tighten the large bolt on the tensioner to a torque of 20 Nm
11. Check for correct fit
12. Lock the camshaft. Tighten the camshaft gearwheel bolts: 45 Nm. Use a wrench to counter-hold
13. Remove helping tools
14. Turn the engine two rotations by hand
15. Repeat the procedure if required
16. Fit the vacuum pump
17. Refit the crankshaft pulley. Tighten torque: 20 Nm + 20 degrees
18. Fit the timing belt cover
19. Refit the valve cover
20. Fit the ancillary drive belt
21. Refit the inlet air manifold hoses
22. Check the injection timing

Torque settings:
Camshaft gearwheel: 45 Nm
Tensioner pulley: 20 Nm
Crankshaft pulley: 20 Nm + 20 degrees

* take nail polish or paint and place a mark starting on the front roller pulley and going onto the front roller metal shaft
* then try to walk on it and see if the white mark separates
* if it does then the roller is bad and would need replaced or tap screws placed through the pulley into the metal shaft to hold it in place
* if it doesn't separate then the drive belt is slipping and most likely will need replaced, although you could try spraying belt dressing on it to see if that would be a temporary fix.
* if neither of these is your problem and the walk belt is slipping then you will need to try to adjust the screws in the back of the treadmill through the end caps. these are allen wrench screws.
Tighten each one the same amount such as 1 full turn to start with.
see if you can now walk without it slipping.
If not then tighten 1-2 more turn on both sides.
If after 2-3 full turns it is not tight enough
I would recommend replacing the walk belt.

Hopefully this helps with your problem!
