Belt replacement sticky?

Recommended Posts

Iwejun

Is there not a sticky article on replacing the V belt for a 2001 5.7 carbed  engine?  I think I know how to do it but would like to confirm my idea, and trust me I’ve  looked but have yet to find it.  TYIA

Not to hard to do, maybe a few more things as this is all from memory...

1.  Loosen alternator 

2.  Remove bracket for raw water pump.

3.  Disconnect hoses that might be in the way.

4. Take off old belt.  

5.  Replace belt and reattach everything else.  

6. Adjust tension on alternator and tighten bolt.

If you have the old belt any auto parts store can match it.  If not, take some string and go around the pulleys and you'll have your measurement.

is it really this easy??

Second day of vacation and I find the V-Belt broke on my 2000 LSV 23.

New belt was $10 at JC Sports in Clemson - great guys!  New tools from Harbor Freight were $20 - cause mine are at home in Chicago...

I've removed the bracket and loosened the alternator.  A PIA btw...

I tried pulling the impeller housing from the shaft, but that's not happening, unless I'm missing something.  Should I focus on removing the hoses instead of pulling the impeller from the shaft?

Can I remove the hoses when the boat is in the water??  I don't mind some water in the bilge, but don't want to sink her.  Taking the boat out of the water will be a PIA as the launch is over a mile away and I don't want to run it without that belt.  

Thanks in advance for your help!

On your 2000, the water from the inlet first goes through the V drive housing.  Leave everything connected to the V drive.  If the water enters the V drive above the water line on the lake, you should be fine to pull your hoses.  Be prepared to lift the hose that comes from the V drive to the raw water intake up into the air above the water line to prevent a bunch of water rushing in.

Of course, that step is easier if you have a shut-off valve anywhere between your through-hull intake and the supply line to the raw water pump.  Either way, you won't sink your boat if there's a loop above water line.

When you pull the second hose off, the one shaped like a J that carries water from the pump housing to the transmission cooler, you will get a bunch of water dumping out of the engine.  Dump to bilge and it's fine.

You need to loosen the L shaped bracket that attaches to the side of the pump housing.  With the hoses off, the entire pump housing will spin freely on the shaft with that bracket undone.  Loosen the bracket where it connects to the other bracket, don't loosen the bolt connecting the L bracket to the pump assembly itself.

Now just loosen the tension on the belt by loosening the alternator and it'll come right off.  Reverse process to re-assemble.

Because the belt on a Monsoon has to go behind the raw water pump which is attached in 3 places other than the pulley.  1, the bracket, and 2 hoses.
