Is my Excel V supposed to have an air filter?

In my ongoing quest to resuscitate my snowmobile, I've removed the seat, gas tank and airbox in order to clean out the mouse nest. And what a nest it is! The airbox is jammed to the top with white nylon fuzz, cardboard, seeds, and leaves. There is a white plastic tube/spindle running down the center of the airbox. There is no air filter anywhere in here. The plastic tube, which connects the innter portion of the airbox to the outer portion, has had a hole chewed through it. Is this white plastic tube supposed to have an air filter on it? Is the nylon fuzz the remains of that filter?

Anyone care to shed some light?

I'm beginning to think that TY ain't where it's at when it comes to tech help for vintage sleds. So far it looks as if I've got a tally of about $400 worth of repair parts that are necessary to revive this machine. Al's Snowmobile in Vermont looks like the place to buy, but I'm flying blind here.
 

There is NO filter in them. It is just an "air box" designed to silence the air intake and keep snow dust from getting into the engine. Clean it out, put it back together and you will be done with that part of your project.

Good Luck, opsled
 
Thanks, Opsled.

I think that I'm going to modify the airbox this time by ADDING a mouse-resistant screen in there. :mad:

Excell V shares some parts with the SRV depending what year you have. WE tried to put an Excell V motor in a SRV but the tapered shaft was to short on the EXV and did not align with the secondary. What parts or questions do you need or have ? My brother-in-law had one of those BOAT ANCHORS and I did much of the ( broken bolt, frozen shaft, worn out clutch etc. ) maint with him over my shoulder so ask away.
 
Well, I cleaned the HUGE mouse nest out of the air box, which necessitated the removal of the seat and fuel tank. I thought FOR SURE that I'd have to scrap the carb because the starter plunger was stuck fast in the bore, but I was able to get it loose by applying heat from a pencil-tip brazing torch.

So far the shopping list stands at:

Carb gasket, needle & seat kit
crank gasket (stator-end)
crank bearing (stator end)
two new pistons & rings (I broke one while beating it out)
upper end gasket kit
hone of the cylinders
Tygon tubing for the fuel tank, oil tank & lines
fuel filter
The left ski is bent up and needs repair or replacement.
New rod ends in the steering linkage.
Seat Re-cover as the vinyl is cracked and the luon bottom has rotted.

Actually, I think that's it!
 
Do yourself a favor on the fuel/oil lines and go to the dealer and buy OEM line. Most aftermarket line is very poor quality in comparison to OEM. The OD and ID are usually different than OEM so it is hard to get aftermarket line to fit right and the OEM clamps won't work. The new OEM oil injector line that goes from the pump to the manifold has a larger OD than the original 1980 line so you will have to buy 4 clamps for it but everything else will fit perfect. I have put new lines on many of these old Yammies and I can tell you that once you have done it both ways you will never use aftermarket again. It will take twice as long with aftermarket, you will run into routing problems, kinking issues, clamp issues, fitting issues and it won't look as good or last as long. You can put all new OEM line on that sled for less than $50 (probably more like $30) and to me it is well worth the $ especially when you are doing an expensive restoration. A line failure due to cheap line can destroy and engine at worst or just be a pain in the @$$ at best.

I have parted 2 1980 Exel-V's in the last year and still have quite a few parts arond here for them. I don't have a good carb but I should have skis and many other things. PM me if you need anything.

Good Luck, Phil (opsled)
