What kind of hose is this(blower to hx)?

[jcooper]

Is this the same type of hose?

Blower exhaust goes through it to the HX. Sapphire list the hose as "HOSE, FLEX 3 IN HIGH TEMP" part number #16-035.

Raising and lowering the blower(belt change) maybe ripped it... Not sure.

I see a lot of Marine Exhaust hose used.

Could be this also.

I used it on my rebuilt back-up unit. It only has a few hundred hours on it since installing but have not had any problems yet. Sure was a lot easier to work with than the very hard marine hose.

The marine wet exhaust hose with the embedded wire is much easier to work with if you peel out the first 12" to facilitate installation. You then have some 'give' to slide onto your hose barbs. A little silicone spray also make it easier to slide onto a point where you can clamp securely.
I cut my barbs down a couple of ribs and use heavy-duty clamps, not the standard gear clamps.

The one in Richards photo/link or the one in my link?

Have you done this on a sapphire, Rob? Geez, I sure hope there are no barbs!

Not sure how the automotive hose would hold up under vacuum. It lacks the internal wire found in marine exhaust hose.

You are in the land of many lakes. Just stop by your local marina, they should stock it.

I have some 3" marine exhaust hose in stock if you are in a hurry.

That "SS" hose won't handle the temp of modern TM's. It will get brittle from the heat.

We use Hi-temp silicone hose, and sell it in 6" increments in 2.5",2.75" & 3" I.D.s.

It is also more flexible for easier installation.

We also use the H/D. bolt clamps for secure TM connections:

I think most all the silicone based hoses are pretty much the same. Like Larry said the marine hose becomes hard as a rock after some time and is very hard to work with. You don't have to worry about collapsing hose on the discharge side.

I had a duh moment...

not sure what tore that hose Coop (they're damn tough from my experience )
Have some suspicions it from jacking up blower off a stuck on hose.
Clamps off, the thing is still "stuck on" pretty good

If that shoe fits, get a bigazz set of Channel-Locs and in the future grab the hose and give a little twist at top and bottom to break loose the crud/heat bond that always occurs


..L.T.A.

Yea, my mechanical skills are most likely what caused the issue! Had to replace the blower belts(first time for me) and was having issues after(no suck - posted a month ago or so about it), kept thinking it was blower and kept tightening the belts. Ended up pulling the hx tube up higher than the other tube. Bet that's what ripped it.

Actually Larry, you were extremely helpful in the other post about not having(or inconsistent) the lift I should.

I'm still having issues, one thing you asked I have noticed seems to be happening. You asked if it happens when the unit is cold, warm and a bunch of other stuff.

Well I'm definitely noticing at the beginning of a job my lift will only go to 11-12(with vac relief tight as it will go), I'll come outside when done and hand over vac lift will shoot up to 16! It's like I need to adjust my vac relief during every job.

it's a seal/gasket/airleak "somewhere" that's warming/softening up enough combined with vibration and vac load while cleaning that seals it

tank lid would be the first place I'd look

Blower belts should be designed with an idler so belts can be changed without moving anything.

 

[Larry Cobb]

Belt Idlers can reduce belt life significantly

on the short distances we operate with on TM's.

Diameter of the idler is a factor.

 

[Lee Stockwell]

Not a well-formulated idler.

 

[Larry Cobb]

Most TM manufacturers do not utilize the large diameter idlers required to preserve belt lifetimes.

One design we submitted to Gates cut belt life to a few hundred hours.

 

[Lee Stockwell]

Was that the one on Brummett's machine?

Wish I had a superior belt tensioner on my chevy 6 liter. So I could get more hours out of the serpentine. What were they thinking using a 120 inch ( 10 feet) 1 inch wide belt to drive a 56 blower?
