Review: GOOD PRODUCT - WORKS GREAT
Review: Unfortunately tool was defective - Unfortunately the product was defective and was returned. The tool was not machined precisely enough for the attachments to screw into the base tool. Only 3 of the 4 holes would line up enough for 3 screws to insert. As the purpose of the tool is to apply quite a bit of torque in order to remove the bearing retaining ring, it is important that the attachment sit flush on the base of the tool and all 4 screws secure the attachment firmly to the base. We would have crossed our fingers and tried the tool with just the 3 screws, but again, lack of precise machining left the tool defective. The square hole at the top of the tool base was not square/too small for a standard driver head to insert properly. We tried a second handle (with a different driver). We tapped gently with a rubber mallet (and not too gently when frustration set in), but it was a no go. The attachment was the proper size (teeth spacing and size) for the old Yamaha we were working on, if only the tool was not defective. We received our refund with the ease of other purchases through desertcart. Thank you!
