Correct torque on flywheel nut for troy-bilt tb 320 blower

Rebuilding a troy-bilt tb 320 blower and need to know the correct torque for the retaining nut that secures the flywheel to the crankshaft. Also the correct method to hold the crankshaft while torquing the flywheel retaining nut. Appears one of the two holes in the crankshaft counterweights can be used to install a 0.170" drill rod that would lock the crankshaft against the connecting rod while torquing the flywheel nut? Some of the other methods discussed at other websites sounds crude (jam a rope into the cylinder head?, etc)

SOURCE: blower wont run at full throttle

Start with the spark plug it is the easiest.

But sounds like the carbourator is dirty, Probably fouled with old gas varnish. When it is idling give it a little throttle, flip the choke on and then full throttle. If it goes full throttle and doesn't conk out, it is a fuel issue.

Good Luck

Sounds like you need to take the carb. apart and clean it. I like to use a Den Tek Brush, (used for cleaning teeth), to clean the small ports in carb. they work great for this job. Make sure to either clean or replace the small screen in thcarb. as well.

SOURCE: Troy Bilt in Hell String Trimmer TB465SS Running Problem

You need to clean the carb. or you may need to buy a carb. kit. But do a cleaning on it first. If you need tips on how to best do this, just let me know. Also check the fuel lines for cracks. As they age, they become brittle.

SOURCE: can not remove troy bilt weedeater head

Once all the bolts are removed, tap all the way around, (with a rubber mallet), where the head meets the bottom portion of the motor. It should come right off with a little coaxing.

Troy bilt tb 240 mower revved out of control about 30 seconds, stopped running then immediately seized up


sounds like the spring on the governor or carb came off and went wide open. that will lock an engine up quick. pull the spark plug and see if you can turn the engine over. if you have to take off the shroud that covers the flywheel, pull rope assembly. try to turn the engine over by hand. squirt some oil in the spark plug hole. you may be able to free it . the starter cord should be free off the engine. maybe it just got jammed.

I just replaced the auger belt and the auger cable has no tension. What do I do to fix it?


Here's some silly questions: Did you put the belt on the correct side of the Tensioner?
Is it the correct sized belt?
Is there a spring on the cable for the auger that can be lifted up the cable to expose the adjustment nut ?

Which gas line goes to the top of TB 320 BV troy built leaf blower. 41DS320G966 carburetor 753-04338?


I suspect it is the one from the gas filter in the tank. If that doesn't work switch the lines around. Hope this helps. If not let me know if it has a primer bulb or not and I will try to help. Hope this helps.

PULL ROPE IS STUCK ON A TROY BILT BLOWER


Partial disassembly of the machine will be required to access/diagnose the exact problem. The starter/recoil unit goes on top of the flywheel and the flywheel is on the engine shaft. The obstacles will be removing the main cover (and getting it back on correctly). If you have never done this, them maybe take pictures as you disassemble it to help you reassemble. Once you reach the starter/recoil unit, you will see how it works and be able to resolve the problem. Some of these units have inferior design and engineering flaws where they mate nylon parts with metal and of course, the nylon doesn't hold up. Post back for more help if needed once you get to the starter unit.

Replacing the pull cord on my Troy Bilt blower/vac (TB320BV), & I can't get the nut off the crankshaft extension, the last thing keeping me from the starter housing. I've tried clasping the flywheel...


Same problem here.After snapping a couple fins off the flywheel trying to lock it with a screwdriver, I had an idea that worked quite well.I used an oil filter wrench (designed like pliers) Item #36778 at harbor freight.The thin design held the flywheel well (very tight fit,had to force past the plastic housing) while I used a socket and power handle.Worked for me and used it when torquing the crankshaft extension nut tight again.

Troy-Bilt Mower is running real slow like its clogged dont know not a mower expert, need help please before I take it to a mower expert.


If you can, check the flywheel key. If it is bent but not quite broken, it can cause slow operation. To do that, take the starter off the top of mower. Take off the big nut on the flywheel. Find a nut of the same size and place on the thread you took the nut off, but only a few turns. Hold the flywheel with one hand, lifting a little, and tap the nut with a hammer with the other hand. The flywheel should come off. Look at the key, it holds the flywheel to the shaft. If it is bent or broken, that is the problem. Replace it and go about your day! Good luck...Lee

Troy bilt tb320bv wont start. only two months old.he cord won't pull out completely like it used to and it won't let me start the thing any longer. It is like something is jammed in the system.


It seems to be a usual problem with troy bilt trimmers and leaf blowers. There should be a half moon piece of keystock that holds the flywheel on,sometimes its known to sheer off. Could also be one of the keepers that hold back the plastic disk for the cord comes loose,it gets in a bind. Either way,you have to open up the case and see whats going on.
