Craftsman Weed Trimmer Repair
I have a 5.5 H.P. Craftsman weed trimmer, model # 536 77360000. I ordered a new part number 740299MA(a "height guide"). The part that was shipped has a bolt that is slighter larger than the diameter of the bolt from the original part. Sears tells me that the original part with the smaller diameter bolt is no longer available. It seems my only alternative is to modify the new part using the original bolt so it can be attached to the trimmer.
The bolt on the new part is spot welded to the "donut", which spins underneath the weed trimmer and comes in contact with the ground. Do I need to remove the spot welds that attach the new bolt to the donut and weld the old bolt in its place (and run the risk that the weld may be imperfect and not perpendicular to the donut)? Alternatively, can I just drill the old bolt out and replace it with the new bolt without welding it to the donut. If the latter alternative works, is there some combination of washers I should use so that the donut will spin properly? Can you think of any other way to fix the trimmer?
Thanks so much
