What now......

Got things fixed on the the TM. Had work done on the van. Ready to go....for awhile.
NOT!
Van has been knocking and has some slight hesitation when accelerating.
Mech looked at it and can't really get it to replicate same symptoms I hear.
TM vac gauge shows an air leak somewhere. Lift at about 6" with hose and wand.
Redid wastetank lid gasket today, now; it Shows about 7" of lift at full speed with 100' of hose and wand. Usually is 9+ with hose and wand at running speed.
Do more crawling around in the back, and poke a round tomorrow.

Crank Position Sensor on the Van

Vac Leak is often the dump valve leaking for me.

The thing with the crankshaft position sensor is that it will not throw a code most times and the engine will run fine while on a lift and not under the load of being on the street. When that sensor goes bad, the timing will always be screwed up and cause the engine to bog down, have no low end power, and can cause some knocking due to the timing error.

Did you ever find out what’s wrong Matt ?

Take your hose that goes from the waste tank to the blower loose at the waste tank. Now start the unit, put it on full throttle then use a piece of wood to slide over the end of the hose your vacuum relief should be on the blower. See if you have the 14hg of vac it should have. If it does then reconnect the hose and block the vacuum ports at the front of your unit see what your vacuum is. If it is good then you have hose issues. If not then you have waste tank issues.

Been very busy, like heat exhausted type of busy.
Ace; i did the block the vac hose- got upto 14" of lift.
best i can determine;
afew years back i did a mod on my waste tank. went with a 2.5" hose to my rc99 filter, then a short 2.5" hose after the filter. Then down to 2" the rest of the way.
Well part of the 2.5" off the tank goes infront of the TM by the exhaust pipe.It melted alitte and the hose caved in(just alittle bit). Ill try to post a pic. A couple weeks back I replaced the melted part of the hose. Thats when i noticed a difference in the lift gauge.
-functions properly, its just the vac gauge dosnt go up much. Get good performance at the wand.

now back to recovering from the weeks work.....

fyi.. found a great place for flash cuffs. about $25 for 2 sets. alot of places are $18-20 per set.

so i think the melted hose gave a high vac lift reading.

Makes sense to me Matt, glad you have it handled. Even happier to hear that you are so busy! I'm doing the 6 days per week grind with no end in site, but for small money delivering mail. I have only cleaned about 6 times in the past month....it is just completely dead. My day does consist of 6-10 hours of fast waliking in the heat of the day, so I know what you mean by exhaustion. According to my watch, I walked 82 miles this week alone.

At least I am really tan, lost 20 lbs., and my legs are freaking toned so I have that going for me.

Glad to hear that you got your unit going. Glad to hear that you have been busy.
Been busy myself, got two refurbish jobs going on and a pull and reinstall that's got to be finished by Tuesday. Plus trying to get things put together to start building a new shop. Hopefully this time next year we'll have the shop up and running. Then we became a thorn in the side more than ever to a couple of shops.

I ditto what Bob and Ed said, glad you're busy !
My question is why in the world your machine is butt naked ? Lol

Maybe I should replace a section of.hose. A jackass ran it over when inwas cleaning. It doesn't look bad though.

If you are just replacing a section of hose on the machine, don't use cuffs. I used to connect all of vac hoses with rigid pvc tubing. It will fit snugly inside the 2 inch hoses and allow you to just push the hoses together. I did it that way on the jobs for 3 years and they never leaked air, pulled apart easy enough when needed and cost you next to nothing. Just buy some thin wall pvc tubing and you will be surprised.

Wait, what ?? Are you talking about putting the pvc tubing in the inside of the hose and that connects to the inside of the blower pipe as well as the inside of the snout that comes out of waste tank ?? I would think over time the pvc tubing that was in the waste tank snout will move towards the blower due to the suction pressure from the blower ?? Unless of course if you glue that tubing to the hose.

I am talking about using rigid pvc tubing to connect 2 pieces of hoses together instead of cuffs.  I would not use it to couple up to the blower or something, but I used that method before buying hose cuffs and it worked really well.  The tubing never got pulled through the hose, easy to disassemble, and certainly cheap.
