Question: Do I Need Gasket Sealer?

1869253

I purchased a new carburetor for my Troy-Bilt
trimmer model number TB-80 in addition to a new carburetor o-ring and air filter gasket. I was wondering if I need to use any gasket sealer on either filter & what type I should use.
I would really appreciate any help anyone could provide regarding this repair. Thank you!! Parts purchased 753-06190, 753-06185, 753-06253.
WJA
Hello 1869253 ,

You don't really need gasket sealer, but if you do feel the need. Purchase a small tube at a automotive parts store. And don't use too much a little dab will do ya.
I know that it isn’t rocket science to attach a new carburetor but I am not having any luck at all. I’m going to go to Lowe’s and get the quick start bit. If that doesn’t work, I’m going to invest in another trimmer for the money that I spent trying to repair this thing.
Question: Carb

1738908

do you sell just the primmer bulb for the trimmer troy built tbc0ec
Hi They probably might, but it is easier and more economical to get one on ebay or amazon. You may even be able to get one at Lowes or Home Depot.

Question: Flywheel Assembly

kingmb

Does the flywheel part number

753-06246

come with the two white dog ear parts that are held on by a clip and a spring or do you have to order them separately?

thanks,

kingmb
WJA
Hello kingmb,

The 753-06246 Flywheel Assembly. Does not include any of the parts your asking about. They would have to be ordered individually or they might be in an assembly.

Question: Frustrated

tylski86

While using my trimmer today the "head" just quit spinning, I opened it up and the gears inside the box assembly are just shredded, wondering if the B-16 gear assembly is what I need to fix it??
WJA
Hello tylski86,

The part number 753-06571 Gear Box Assembly would be the part to order if the gears are gone. Also check the ends of the 753-05267 Lower Flexible Drive Shaft. To make sure they are square and fit into into the Gear Box and The Upper drive shaft securely.

Question: Model TB80EC TroyBilt Trimmer

ROADBLOCK

How do you access the carb adjustment screws on the TB80ec
Without the specific tool for those screws, you can improvise. Diaphragm carbs nowadays have 4 different types of mixture screws used in them 1. Splined (pretty common) 2. D-Head 3. Double-D Head 4. Pac Man
In a pinch you can use a 22 gauge automotive wire connector. I like the female spade terminal connector. These connectors are plastic, so they expand somewhat and grip the screws. Tap one of them onto the screw head until tight, and then adjust. I use the female spade part as the handle. Careful adjusting, as these carbs are sensitive. Here is a LINK to the proper way to adjust a carburetor on the Troy Bilt.

Question: Lower Shaft Replacement

elzie

the spring loaded button that positions the lower shaft with the upper shaft broke. having to order part because I can't use a screw to keep shaft from rotating in use because the drive shaft runs through. the top is easy but was concered that the lower part would be tricky to put into the housing that curves downward. are there any springs or items I should be aware of before taking off the old lower shaft? the unit is only a year old and has been used maybe less than 20 times.
WJA
Hello 1203598,

The replacement of the 753-08164 Lower Boom Assembly, should not be difficult. You will just need to remove the 753-06571 Gear Box Assembly and the 753-06123 Shield Assembly. There are no springs or hidden parts that you should be concerned with. Just make sure you line up the drive shaft into the coupling and Gear Box, and you should be good to go.

Question: Gearbox Assembly

cote1966

Can I order a straight gear box instead of the angled gear box? The one I ordered did not last but one season
WJA
Hello cote1966,

I don't think another gearbox assembly would work on a different model trimmer other than the one it has in the parts diagram. It may not connect correctly with the model you have.

-WJA
Question: Upper Drive Shaft And Housing As...

dolphin1

can you get just the upper drive shaft without the housing assembly
WJA
Hello dolphin1,

On this model the only way you can get the upper drive shaft is by ordering the part number 753-04344 upper drive shaft and housing assembly.

-WJA
Question: Gear Box Assembly

1151943

this may be a really dumb comment- I am assuming that the gears and ball bearing are inside the part as shown and are included in the assembly price. Is this correct?
WJA
Hello 1151943,

Your assumption is correct. All the gears and bearings are included in the 753-06571 gear box assembly.

-WJA
Question: Discussion For Gear Box Assembly...

jriggen

Is this part the same as 753-06571 that is used on a Craftsman weed trimmer? The part looks the same but that doesn't mean much.

WJA
Hello jriggen,

You can consider yourself safe in ordering part number 753-06571 for your Craftsman trimmer. It's probably made for Sears by the company that manufactured that one.
