belt size?

[williambogner]

I do not have the amphibious home right now. Can anyone tell me what size belt goes on her. Its a max II with a t20 engine and briggs 14 vanguard. Any help would be appreciated. Thanks!

[williambogner]

does anyone know the specific model number or anything? would napa or autozone possibly have something very similar?

[Eldon]

They certainly would if you knew the size.If you follow the posts of the past month you will see that I have tirelessly attempted to find a size for my Max II 850T,so far no luck.I have read that all Max take a 1 3/16" wide belt .Other than that you need to know the length.When you have this information Napa and others can find one.The challenge is: by the time you need a belt your old one will be worn narrower so of course you no longer know the width and it can also be stretched so you cannot be sure of the length either.Further you could have a broken or shredded belt.Most on this forum call R.I. with model and serial number and they can ship one to you.I'm in Canada and that gives an extra curve as we have a Canadian distributor but to my knowledge they don't stock any parts.The number on my old belt though made by Dayco cannot be referenced by them.I wish you luck but if you are in the U.S. just give R.I. a call in Buffalo.You will pay a premium for something that will be found in your corner auto supply place but you will get it.

can someone PLEASE! help me

alrite on my 1993 max II. i need to replace the drive belt. The number on the belt is 15252aa made by dayco. I brought it to napa and they had to idea and i found a crossed number hp2013. I order that and im struggling to put the belt on. Even if i get it on it would be too tight....can anyone help me? I just spent 30$ on this belt and might even not need it.

How are you putting the belt on? Do you have the engine completely unbolted from the frame?

If you have enough space between the engine drive clutch and the body, I would install by getting belt through that gap flat side against body then first around the drive clutch.Making it onto the secondary (trans) clutch will be possible only if you have enogh strength to rotate the sheaves in opposite directions and spread the sheaves apart this is not easy but possible to do after the belt is laid partially onto secondary clutch. If you can separate the sheves and slide the belt downward you will be able to thread it around. If you try to wedge a board to open sheaves you will need a second one nearly opposite or you are just cocking and jamming. Freeing the engine from its mounts as Mike suggested is more foolproof although an experienced snowmobiler can do it my way much quicker. Removing requires spreading sheaves, slidinng belt all the way down and the unthreading from the secondary first.

no everything is intact on the machine...the belt says hp2013 from dayco. is it right cause its really tight if i were to get it on. also if i match it up with the other one that is complete shot its not even...

[Mike]

Yeah, if you can't get it on take the motor loose. It's only four bolts and then you don't have to mess with it anymore.

[bigmandengo]

that belt is too short(hp2013-40 3/4") the correct belt is a dayco max 1039 -3/16x 44 7/8"

[turvuren]

How tight

Does anyone have an opinion on belt tension? I squeeze together at middle and measure the gap. Of course the belt needs to be at the top of the secondary. My Attex Tomahawk measures about 2" and my Buffalo is real loose-an inch or less-and still works ok. It seems to me a looser belt engages at a higher rpm and gives more speed, at some point belt will slip and fry itself.

The new number on the Dayco Max3039 is HP3003.(44 7/8"X1 3/16").This mumber is my last hope if I can assume that my old belt could stretch 3/4" in 200 hours.Seems reasonable to me.

The proper deflection on a Max is 1 3/4" measured by depressing the top near the middle.

[williambogner]

alrite guys, i called my local auto parts store and they said that they'd accept the wrong belt back. They said they could order hp3003 and be here tuesday. Are you sure that that number belt would work on my Max II. I dont want to order the wrong belt again. Dayco Max number-1039 did not cross or anything. Should i order it??

[Eldon]

I can tell you when it comes to drive belts nothing is certain.My information comes from page two on the Max Forums in which there is a thread that I started on a "Drive Belt for Max II 850T".On this thread Mike posted a link for Dayco belts in which the Dayco Max Belts are listed by number and dimensions.I learned that Dayco sold a portion of their belt business to Carlisle and renumbered their remaining belts.On this thread is a cross reference from Dayco Max belts to Dayco HP belts which I placed there by means of a link.Many will tell you the simplest way to get a belt is to contact R.I. with your model and serial number and they will ship one to you.Not bad advice either.
