Question: How It Install Lever?
I own a B&D st7000 electric trimmer/edger. It stopped feeding the line out. Reviews say it could be the feed lever #57 or part #598437-00. How do I go about taking the old one off and putting a new one on?

I want to be clear that I have NOT yet done this repair, but do have the same problem and have successfully taken the unit apart. I am ordering the lever.
Remove the cover, spring and string spool.
Remove the string guard by removing 1 screw from underneath, and then rotating the guard to allow it to come off.
Loosen 7 screws holding the 2 halves of the housing together. You don't even have to remove them as long as they are completely loose. While they do have a standard flat-blade screwdriver slot, it is shallow and likely dirty, so removing them is easier with a T15 Torx driver.
Cut the 'For Edging' label along the joint line of the 2 halves.
Carefully separate the 2 halves of the housing. The handle will come out [easy to figure out how to replace] and the motor can be lifted out. Note how the wires are routed.
You can now remove the lever. My lever was very loose in its bearing bore. You will have to destroy the plastic latches on the lever shaft on the outside of the spool housing [which is attached directly to the motor] to allow the lever to be removed towards the spool cavity. I used a screw driver and countersink and GENTLY mashed the latches and drove the lever out.
From here, it should be a simple matter to put in the new lever, as it appears that it will snap into place, and reassemble. I am concerned that the bore in the spool housing is worn in addition to the lever shaft itself. If that is the case, I will have wasted $10 attempting to repair [part cost S&H -- order something else, like a spool or cover to avoid wasting the $5 minimum charge]. However, I am willing to take the risk. It appears that the housing bore is about .201" Dia. and the lever shaft just under that. I cleaned out the housing bore by turning a 13/64 drill bit BY HAND in the housing, just to get the dirt out. Be careful not to damage the shoulder at the bottom of the bore as that is what holds the lever in place when it snaps in.
I hope this helps, as there was no date on your inquiry.

Here is how I just changed out my lever. Remove the cover, spring and string spool.
Next, I pried out the old lever with flat screwdriver, and popped the new one in. Done. Took about 10 seconds or less.
Question: String Feeder
Have bought new string and reels and still have the same problem. The string will not auto feed out.

I would guess that the problem is with the Feed Lever, item #57 on the parts diagram. The feed lever seems to be the weak link on this style of trimmer. It is part # 598437-00 and is available from http://ereplacementparts.com.
Good luck with your repair!
Reply: Auto String Feed
The feed lever on these trimmers seems to wear out fairly quickly and cause the problem you described. The feed lever is a simple part to replace and should solve the problem. It is part #598437-00 and is available from http://ereplacementparts.com.
I hope this helps with your repair!
