If it takes you back to your model number & serial number, simply enter your model number and any random number for the serial. You will be able to access the manuals from there.

I hope this helps.

SOURCE: TB70ss clutch

Check to see if there is any material collected around the base of the head, around the tube that provides the energy to spin. It may cause the power to be diminished a great deal, so that must be cleaned away thoroughly. Check to see if you can spin the head freely by your hand, without the motor being on. If not, it may need lubrication down the indide of the power shaft. A light grease would do that, or even a heavy oil poured down the shaft, but not too much.

SOURCE: TB70ss Trimmer runs but does not turn the string

Remove the angle drive gearbox near the string head and spin it to see if everything is moving properly. You may have stripped the gears out of it.

The motor runs but the trimmer head turns slowly or not at all.

The problem may not be in the clutch assembly, if you took the engine apart you would have noticed a lot of debris if a lining had been stripped off. I would start with the lower flexible shaft assembly. This is probably where you will find something that is noticeably worn.

Here is a link to a Owner Manual / Parts listing. So you can see what the pieces should look like.

If the link doesn't work here's where you can download it for free.

How come there are no manuals for the troy-bilt Model#303531 / TB340 XP? Not even on TroyBilt website.?

The unit may say "troybilt" on it but may have been made by another company, like MTD, RYOBI, or Homelite. Check out those manufacturers.

Starter rope on Troybilt TB575SS

try removing the starter housing, inside will be a large white or black wheel, visually inspect to make sure the componets are not damaged and that nothing jamming it. try using a lithium spray grease to lubricate the componets. if it still doesn't work the inner coil is probably damaged or came off track. it is very difficult to fix or replace this coil. i suggest taking to your nearest service center but if you would like to try it yourself, let me know and i will give you further instructions.
