Hi, i am Florencio Valiente looking for grass cutter spare parts please help me to it. STIHL FS55C.. unit cranck shaft assembly, 1 set spiral gear asssembly pls. advice..

new carby from stihl or e-bay
spares from stihl

sounds like the shaft isn't engaged properly at the engine end or the cutter head. or the inner shaft could be damaged, but most likely it will be that the head isn't on properly

If you're refering to the item i have highlighted then remove the driveshaft from the plastic flexible liner, clean shaft, re-grease and replace. You'll probably fing the shaft has become dry and has rubbed, causing it to get hot. The plastic liner should not be spinning in the drive tube assembly so you may need to get a new 'flexible liner' that fits snug.

Hi, have you ever cleaned the unit out? If you have air pressure available, this is the easiest way to do it. Blow all the old dead grass, weeds ect out from the engine area of the Weed eater. If you don't have or have access to a compressor, take the unit to your local garage/service station and ask to use their air, or ask them to blow it out for you. This alone may cure the problem. However the proper mix is critical for proper performance also. If the mix is too lean the unit will over heat. Clean it out, and be sure of the mix ratio. You should be 'good to go'. Good Luck Vern

First take the head off and look for grass, weeds and string wound up in there. A lot of times that's the problem.

Next, with the head off and the switch in the off position, pull it over a few times and see if the shaft spins. If not, could be a broken shaft or a bad clutch.

The Metal Clamp referenced clamps directly on the end of the '2-Piece Gear Box Assembly'. The gear box assembly is an aluminum casting held together by 3 machine screws. The Metal Clamp does not actually lock the drive shaft housing into the gearbox assembly. The flexible drive shaft cable engages the engine output shaft, and the gear box assembly. This is a fixed length (non-adjustable) assembly.

First ensure that the drive shaft assembly is fully engaged at the quick connect fitting and that the "snap" is engaged. Then make sure the knob is fully tightened. The quick connect allows you to quickly switch between various attachments offered on this unit.

Now, based on your description, it sounds like the 'anti-rotation screw' 791-182519 has backed out or is gone. This will allow the entire cutting assembly (gearbox forward) to slip off of the drive shaft housing and disengage the flexible drive shaft. If your cutting assembly is attempting to rotate while in operation, or the drive is not engaged as you described.
Do not continue to operate the unit until you get this fixed as you could strip out the drive shaft end or cause other serious damage to the equipment or yourself.

If it is the anti-rotation screw, then make sure to push the drive shaft housing firmly into the gear box and ensure to align the holes in the drive shaft housing and the gear box. If the screw is lost, then find one similar sized, but be CERTAIN that it is not too long as it will actually engage the flexible drive shaft and prevent rotation, or cut the drive shaft.

Back to the clamp: If it is still wanting to move, then remove the lock nut and place slightly oversized washers on the bolt head and the lock nut. This will force more pressure (does not take much) on the clamp and will lock it down.

I just fixed mine today (071809) in fact and had to drill a new hole in the drive shaft housing as the original was completely wallowed out.

I hope this helps.

Hi again Libby. You're right to be scared about further damage. If you want to fix this machine yourself, stop using the mixer. Go to the Kitchenaid website and download the drawings that match your mixer model Unplug the mixer! Take a screwdriver and remove the silver band from around the head of the unit ( 1 screw). Next remove the four screws that hold the top part of the mixer. Remove that cover, and look for a 'humpy" looking cover at the front of the machine. Examine this transmission cover carefully. If the cover is made of plastic, look for cracks. If you don't find cracks, you'be better off taking it to a repair shop. If you do find cracks in the plastic cover, remove the four screws that secure it. Remove the trans. cover.

You will now see a lot of grease in this exposed transmission. Put on some latex gloves, get a bunch of paper towels and move some of this grease aside so you can lift the worm gear assembly free of the mixer ( see Kitchenaid drawing). Wipe it off and look for damage to the worm (spiral) gear. Look for damage on the other gear of this assembly, inspect the 2 bronze bearings at either end of the shaft. You're looking for cracks in, or pieces missing from the bearings, look for damaged teeth on the gear. Should you find damage at any stage, that part must be replaced. These parts can be ordered from the Kitchenaid website, and will take about a month for them to arrive.

When you order the required parts, insist that the replacement trans. cover be made of metal. When my mixer "blew up", my replacement was a metal one. If your problem dosen't fit the above solution. I can't help you further. If it does, please rate my solution.

Depending how much grease you had to take out to do the inspection, you might have to order a container of grease to replace it. Good luck! ricardok45.
