Engine Maintenance - 8x8 Amphibious Vehicle Argo REBUILD Ep.5

Every person with an Argo should be watching this video. This is how you maintain and repair an old Argo.

Looking good Donn! The clutches on that unit are made by a Canadian company called CVtech. The belt definitely looks worn as it appears to have too much slack. It should have some but not that much. They are relatively simple clutches and work well for that application. Check the belt for cracking in the bottom of the notches as typically that is the first place they will start coming apart. Keep up the good work!👍🏻

Красавец! Услада для глаз. Все четко и по делу! Мастерская выросла до уровня фабрики.

Little by little it's coming together again Donn, won't be much longer till you can put it ALL together again. Stay safe and keep up the good work and videos. Fred.

Dude! Allow me to introduce you to my friends: Mr Workbench and Mr Shop Chair. Watching you kneel on the floor all the time makes MY knees and back hurt. 😆

Your belt might be a bit loose but that’s normal for a belt that’s worn since they get narrower as they wear. If you source a new one you’ll see just how much it’s worn down.

I like it when you talk a little bit in your videos, you are so knowledgable :) Keep up the good work. Great watch.

Kohler engine charging stators produce AC voltage to the rectifier and seeing as one of the stator wires has burnt out , i suspect you may have a problem with the stator,,,,, the 2 outside pins on rectifier are the input from stator windings, stator should be producing between 35 and 43 volts AC, voltage lower than 28AC and the stator is cooked,,,,,, the middle pin is DC, stepped down through rectifier between 13 to 15vdc, these kohler engines NEED a good battery and earth, ground the body of the rectifier directly to the block, dont rely on on the shroud for the earth, are known for not good grounding points Donny,,,,, loving the build brother

Hello from the Netherlands.  thanks for the video.  Sincerely Hollandduck

Hey, Donn. Great video, as always. That primary and secondary clutch setup should be inspected and "cleaned," every year. Sometimes you can get away with just blowing them off with compressed air and gently cleaning the sheave surfaces with a 3M scotchbrite pad, but other times you will need to pull them off and take them apart to clean and grease the internals. That belt looks pretty loose. If you have the service manual for that Argo, it should show the tolerance of where the belt sits in the secondary clutch. There may be some small adjustment there as well. Finally, if you really want to be thorough, you can take the belt and give it a quick wash with some dish soap and water. Keep up the good work!

Blue Flame Special. Thanks from St.Paul,Minnesota.

No need to rebuild an engine if it works! Good work. I've fixed and rebuilt a few of these machines. They are easy to work on. I look for the abused and neglected Argos to buy because they are cheaper.

The sound at idle though, LOL

The Kohler engine sounds healthy, nice work and video. 👍

I adjust cvt belt tension by ensuring it is as snug as possible without engaging during idle

I adore an unmuffled four stroke engine sound and to see the exhaust valve stem when it's doing its job is something one does not get to see ,,

The CVT belt is way too loose, should have only 1/2"-3/4" deflection otherwise it is like starting off in 2nd or 3rd gear and you won't have high gear. Loose belt deflection will cause excessive heat in both the clutches and the belt resulting in premature wear and failure of both. Over 50 years experience snowmobile and ATV CVT maintenance and racing I have seen a lot failures.

Love watching your videos Donn. Awesome to see U rebuild, restore, create and maintain everything. Great work sir. Can't wait for the rest. Keep 'em coming.

Painting the floor is how you learn Kung Fu according to Mr. Miyagi. Karate, excuse me.

Hi Donn, there are screw pullers for those primary clutches, screw in the blot hole and pop off the clutch. They both primary and secondary look like they would benefit from a good clean and lube of bushings etc. Same set up in a snowmobile.
