Okay, let's lose all this "Scary" talk.
It ain't that hard if done properly.
Here is the direct link to the '88 Samurai Factory Service manual (Part 1) at Ack's FAQ:
http://www.acksfaq.com/pdfs/sam881_434.pdfPage 3-10 has the procedure for removing the belt.
Pages 3-48 to 3-50 has the procedure for installing a new belt.
IMPORTANT NOTE: The procedure for re-installing the timing belt in pages 3-48 to 3-50 in the FSM
ASSUMES that you have
completely rebuilt the engine!.
Since most folks are simply removing the old one and re-installing a new one, IT IS NOT NECESSARY TO LOOSEN THE VALVE LASH NUTS! The
LAST THING you want to do is to permit the camshaft to turn - which is EXACTLY what will happen if you loosen up the valve lash nuts! In order to maintain the current
correct timing, you MUST NOT turn either the crank or the camshaft while the timing belt is being installed! So leave the valve lash nuts alone!
Once the timing belt is installed - with ZERO SLACK on the non-tensioner side - and the tensioner has been set to take up the slack, you
DO want to rotate the
crankshft clockwise two revolutions to seat the belt and adjust the tensioner again, if necessary. You can do this by removing the sparkplugs and hand-turning the engine using a socket and the bolt on the end of the crank.
Finally, in case you have never heard my rant on how to
correctly remove the crankshaft accessory belt pulley in order to get the timing belt cover off, DO NOT - I REPEAT
DO NOT - remove the crankshaft accessory belt pulley by removing the large 17mm bolt on the end of the crankshaft! ALWAYS remove the crankshaft accessory belt pulley by removing the four smaller bolts that hold the crankshaft accessory belt pulley to the toothed crankshaft timing belt pulley! The pictures in the FSM pages (listed above) illustrate this very well.
I have successfully done this procedure using the above-described technique without pulling the radiator.
I hope that this clears up this misinformation-laden topic.
