Tools you will need;
1x10mm socket with short extention arm.
1x10mm hex socket or 10mm Alan key.
1x22mm socket.
1x torque wrench
1x cambelt kit from roughtrax "optional"
NOTE: It is good practice to replace both pulley & tentioner when changing the cambelt.
First of all make sure the truck is in neutral & the hand brake is on.
Remove the 4 10mm bolts & 2 clips from the cam cover.
Using the 22mm socket turn the crank clockwise until you line the notch on the cam with the notch on the casting "TDC" & same goes for the crank & fuel pump notches.
NOTE: Never turn the engine using the cam sprocket or fuel pump.
If while turning the crank you encounter resistance, leave for 20 seconds while pressure releases & turn again.
Once you are happy that they are lined up you can then remove The tentioner "2x10mm bolts" & the belt will slide off with ease.
Now you can remove the idler pulley using the 10mm hex socket.
Fit the new tentioner & tighten to 7.8ft-lb or 9Nm but "DO NOT" pull the pin. Fit the new idler pulley & tighten to 25ft-lb or 34Nm.
Now slide the belt over the cam, idler pulley & fuel pump.
Push back on idler to take up the slack on the belt & double check all noches are in line. Once happy you can pull pin on tentioner.
One Final thing to do before putting cover on is to turn the belt 2 full revolutions "using the crank" to make sure all is in line & marks are still correct.
Start engine & have a quick look to make sure belt is running in line, once happy, switch off engine & replace cover.
JOB DONE.
IF I HAVE MISSED ANYTHING OR NEED TO EDIT ANY OF THE ABOVE PLEASE FEEL FREE TO MENTION IT AS THE BELT IS IMPORTANT AND I WOULDN'T WANT ANYBODY TO DAMAGE AN ENGINE DUE TO MY WRITE UP.
Thanks si.
