Eric, Most parts look-up only gives a OEM part number for rope.

#3 and #3.5 is the most common used on smaller hand held equipment.

 

Following is a link to Stens online catalog--it may or not be of help to you. Rope size is a subjective question. Personally, I use 3 or 3 1/2 on two stroke stuff, 4/4.5/5 on mid hp range engines and 6/7 on large hp applications.

Thanks Restorob and Dutch. Its crazy that there is no cross reference available to ensure that you have the right rope. You would think that the aftermarket mfgs would consolidate the rope sizes considering that one rope size is .109 and the next size is .125. Could .016 make that much of a difference?

Thanks again

Eric

 

Stens rope seems fairly consistent in their number/measurements. The rope number indicates the number or 32nds of an inch. For example #3.5 represents 3 32nds(6/64) + 1/2 of a 32nd(1/64) or a total of 7/64.

I have several rolls of Honda rope which are very close to Stens measurements and are not close to the corresponding metric number in millimeters. On the other hand, I have a couple of rolls of Stihl rope, #3 and #3.5, which measure very close to 3mm and 3.5mm.

As long as the rope you are replacing is original to the equipment, a reasonably close rope size shouldn't be a problem.

Dutch, thanks for clearing up the size issue. Still seems crazy but at least I feel better that the rope that I used (3.5) is close enough.
