If the engine is running it is a simple act of removing the timing belt then replacing it
WITHOUT DISTURBING THE CRANK AND CAMSHAFT PULLEY POSITIONS.
As it sits undisturbed, the engine's crank and camshaft are in perfect orientation. All you have to do is install the belt so that there is ZERO slack in the timing belt on the side opposite of the tensioner.
Before attempting to remove the old timing belt, read this post thread:
http://bbs.zuwharrie.com/content/topic,89816.0.htmlFollowing the installation of the new belt, re-install the tensioner as you found it before you took it apart. Once the tensioner is installed, Use a 17mm socket to rotate the crankshaft two revolutions CLOCKWISE. Double-check the belt tension on the tensioner side of the belt then snug down adjuster nut to 7-8.5 foot-pounds. Tighten the idler pulley nut to 17.5 to 21.5 foot-pounds.
When you install the accessory pulley, tighten the five small bolts down to 7.5 to 9 foot-pounds. All the above torque values come from the 1988 Samurai Factory Service Manual (FSM) and apply to the 1.6 engine as well as the 1.3 engine.
Should you have the burning desire to download the Samurai FSM (
http://www.acksfaq.com/fsm.htm) please understand that the section that describes the installation of the timing belt is written as part of a COMPLETE ENGINE TEARDOWN AND REASSEMBLY! All the steps involving loosening the valve lash bolts and turning the crankshaft and camshafts to a specific position DO NOT APPLY to the simple task of replacing a timing belt in a FUNCTIONAL, RUNNING engine. Performing those unnecessary steps will only make your job complicated and can lead to TOTAL FRUSTRATION as you try to get everything lined up like it was before messing with the valve lash adjuster and crank/cam-shaft position...
Trust me on this one...
I hope that this helps!
