Removing the A/C compressor belt can be tough. Loosen the 12mm
holding
bolt and the unscrew the 10mm tensioner bolt till there's a 1/4"
of
slack or so. If you still can't remove the belt, try unscrewing
the
13mm mounting bolt just below the A/C compressor, this should
give you
enough slack. When putting the belt back on, make sure this mounting
bolt is retightened. Put the A/C compressor belt onto the bottom
of the
crankshaft pulley and use the crankshaft bolt to turn the engine
and
inch the belt back on. It's a tight fit.
If you have a two piece timing belt cover, you can't remove
the bottom
half until you've taken off the crankshaft pulley. Be sure to
put this
cover back on after you've changed the belt and before you reinstall
the
pulley!
The central bolt on my 245 is 24mm. Lots of people don't have
this size
bolt and you can't determine the bolt size easily until you're
too into
the job to go get such a socket from a store. (Ask me how I know).
Also, depite the fact that the crankshaft is keyed there's
no key to
hold the crankshaft pulley on (correct? I didn't see one on mine).
So
no, if you don't see a key you haven't lost it. There is a big
washer
there- be careful it doesn't fall into the hinterland. You can
put the
manual transmission in 4th and set the break to remove the crankshaft
pulley. You have to pull anti-clockwise REALLY hard but it will
come.
If you have factory belt with alignment stripes on it, use
a piece of
chalk to extend the alignment marks onto the front of your new
belt.
This will make installation just a little easier. The "alignment
dot" on
the lower right-hand pulley is hard to see. Stick a small screwdriver
into the slot and line up with the dot on the pulley to see if
the
pulley and alignment dot are aligned correctly. The belt may be
a bit
small to get on easily- get an assistant to use a pipe wrench
to
compress the tensioner just a little.
