I take it you got the old broken bolt out ok? I need better pics of the pulley and brand name?? All my machines have browning pulleys with them the 2 bolts that tighten are used to to remove ( open holes to tighten threded to remove )
My wife likes the truckmount 😆

I always roll my belts off.

I tried that with a flat head screw driver, then a piece of rope. I Couldn't get it to ride over the lip of the pulley. Have you done that on geared/toothed belts?

It even works on the ones with dentures.

I did get the sheared bolt out! I propped the blower up with a small bottle jack and the bolt came out pretty easily. Nice pulley, mine is stupid, there are 3 holes total, and only 1 hole to thread a grub screw in to pop the pulley off. If there were 2 removal holes on opposing sides I imagine going back and forth a few times would make it come off like a breeze.
If you can't get the pulley off, and you can't adjust the tension in enough to get the belt on. Can you loosen / remove mounting bracket bolts enough to get the belt on?? How about loosening the 4 jackshaft bolts and leave the blower stationary and move the driveshaft in enough to get the belt on. If there's not enough threds on the driveshaft bolts to allow it to move enough to install the belt , maybe remove the bolts 1 at a time and temporarily replace with longer ones to keep everything together while replacing the belt then tighten up and reinstall the original bolts one at a time ???now another thought are you attempting these repairs with the driver and passenger seats still in the van???

Great tips on moving the driveshaft, I didn't have to do that this time since I got the pulley off but I think I will certainly go that route when I need to remove the blower belt in the future. I didn't think to remove the seat! Seems like I don't think enough

Bryce, take it to a distributor and get an estimate for repair. You’ve gotta put a little money in it. Your idea of your porty is good for now while you’re young. Like Doug said that machine won’t require much maintenance, let your distributor do do it during the slow months and your cranking with the porty.

If you remove the seats it a whole lot easier to work. My 2000 i have a squat sensor wire and 4 nuts and it comes right out. Frankenstein is a 2020 and has airbags in the seats. I found you do not have to disconnect the battery to disconnect seat airbags just be sure that the key is off when you disconnect them. Also you can drive the van with the seat airbag disconnected (as in passenger seat still out) you will have a warning light on the dash but it will go out once the airbag is reconnected. It appears by the video below that that was 2 Allen screws holding your pulley on. Looks easier to remove yours than mine. Sometimes mine rusts on and the bolts to remove it shears off and i have to use a puller. Yours the only consern would be to make damn sure you have the proper Allen wrench and it seats properly. Cause if you strip um out it'll be a real pita to deal with. Glad to hear you got it off okGreat tips on moving the driveshaft, I didn't have to do that this time since I got the pulley off but I think I will certainly go that route when I need to remove the blower belt in the future.

Sort of. What he didn't show you was him drowning it in wd40, using an impact wrench, a torch, smashing it with a hammer, cursing, and then repeating that whole process several times for an hour or two before finally breaking it free. Then he reassembled it just to make that short video to get me upset. But we do have the same taper lock pulley.

Air bags in the seats? What the heck do those do, eject you out through the roof like a fighter jet before it crashes?!
I had a feeling a perfect fit was important. I actually drove to the hardware store and bought an appropriate long allen head socket for that pulley. My metric set was too wiggly. After I fixed the blower mounting bolt I realized I need to put the pulley and belt back on separate because the pulley and bushing need to line up perfect and be seated on the shaft perfectly. I ended up loosening the pillow blocks and did your recommended trick using longer bolts to get enough movement on the lower pulley to put the belt on.
I got it all fixed up! Changed the blower oil and removed the salsa heat exchanger and soaked it degreaser and cleaned it out while I had the driver seat out. At first the blower belt was too tight, but it was quiet when I ran it. Then I overcompensated and the belt was too loose and began squealing when I ran it. Then read the manual again and learned the belt needs 1/64" deflection per 1" of span, so a little less than 1/4" deflection on my setup. I think I got it right on the last time. Now it's quiet and isn't scary tight.

Any chance this thing will now run trouble free for 1000 hours?

Probably … since it’s not mine
I don't know the blower belt should if the gear belt is aligned and tensioned properly you should get years of service outa it. As far as the rest of the machine goes, i don't know haven't seen much of it but once you get the power pack dialed in the rest is just hoses and fittings.does your machine have a chemical pump ?

I'd guess the blower belt should be solid for a long while. I think it is aligned and tensioned well. The old blower belt seems fine actually, I'm saving it. The blower sagging down created slack in the belt and was causing the squealing. I'll start collecting hoses and fittings. Should I get some kind of crimping tool or are pipe clamps sufficient at high pressures?
Yes it does have a chemical pump. Although I don't think there is a separate pump for it, seems more like injection. I think it feeds down to the water pump and gets mixed into the fresh water post pump. Haven't used it yet. This week I'll test it out...

Oh I see. I put the doghouse back in and I'm retired for the night. I'll unearth it tomorrow and follow the solution line from the chemical meter to the main pump and see how it interfaces and let you know. All I know is that my setup has a post pump chemical system to protect the main pumps seals. And it definitely doesnt go into a valve cap...
If you have a chemical pump your chemical meter probably has brass fittings and depending on the chemicals you use they tend to deteriorate quite rapidly. The dwyer meters used on machines that use starvation to supply chemicals are all stainless. The way I found this out was all my business life ive had machines that used starvation to feed chemicals. (They have a flow adjustment knob at the bottom of the meter) when i retro fitted frankinstien with a chemical pump i bought the proper dwyer meter and it lasted only 900 hours before giving me problems. The way that i solved it was to take fittings from a pile of old meters that were all stainless and swap out the parts. I have a bunch of um if you'd like to do the same to your meter. I don't have any extra â…›pipe to hose fittings to connect it up but their easy to find on ebay Amazon etc.etc.

I'd love that Dwain, very kind offer thanks bud! Yea I think I have the same setup you took in the pic. I'll confirm tomorrow. Thanks for heads up about the weak point in the system too, and a lasting solution!
Stainless is the way to go eh. I wonder about quick connects though, it seems like they go for other reasons so would it be wasteful to spend the money on them or do they really last? Exciting times. I need to get a pile of hoses and a box of fittings. I am impressed with the selection at my local hardware store, they have a wall of brass fittings that will fit a decent amount of my needs.
