This ebay Buy-It-Now offering is custom designed by me to tune up and convert your old tired and obsolete Snap On IM6100 to use an 8-vane IM6500HP rotor. With my unique offering your IM6100 becomes a Snap ON IM6500HP. That conversion then becomes a much higher nut busting torque producing tool similar to the Snap On MG725 or PT850. If you already have an IM6500HP this kit fit directly to tune up your tool thus improving torque output AND providing a new replacement rotor should your old tool need one.eBay allows me to provide live help to my buyers and prospective buyers by using the "Contact Seller" link on every item in my eBay store. Buyers provide their phone number on the eBay Sales Record for live help after the sale of any of my items. If you email me for through eBay or leave a voicemail I can call you back and provide specific help with your questions. Take note below as I list concerns which are the responsibility of the buyer and keys to success in this simple DIY conversion kit that I am offering. The rotor I provide increases IM6100 tool rpm and torque output by: tuning up (which reduces internal slippage), sealing internal oil and air leakage while increasing torque output by about 190 rated foot pounds. Your cylinder or air motor sleeve should be briefly honed with a brake cylinder hone and thoroughly washed and inspected for cracks and rust pits to make this important repair and upgrade provide you the best results. The IM6100 was basically a tool capable of about 550 foot pounds of test torque after a repair was completed on a tool leaving the Service Center.The IM6500HP Snap on Service Center sheet tool breakdown sheet above shows 650 foot pounds of test torque after a repair was completed on a tool leaving the Service Center. This is the list of parts below is as shown above in my listing photos.1) OEM 8-vane rotor. Polished and deburred. Vane fitment verified. 1) IM6100 / IM6500HP tune up kit with 8-vanes. The vanes are shipped with a rubber band wrapped around them as shown above. I test vane fitment and float before I ship this kit.1) I also provide an additional throttle valve repair kit which I use in my repair business to replace the now obsolete offset red tip valve and white seat with the raised hinge tab combo. Your tool should be supplied with 90 to 100 PSI on wide open throttle through a 1/4" minimum ID sized air fitting. *Most of the low volume air fittings I commonly see on eBay air tools are not correctly sized (as-in too small) for the tools they are installed on. Your air hoses should be at least 3/8" ID internally up to 50 feet and 1/2" for any hose distances greater than 75 feet. Your air should be: clean, dry, filtered and have oil injected daily and often for best sealing results. Your IM6100 tool has a debris screen installed in the ME6F6 steel inlet bushing. If this screen is removed or plugged and the tool has been run for more than 30 minutes with these shade tree mechanic modifications then the tool should be fully disassembled, cleaned and tuned up before installing this rotor and the ME6F6 bushing should be replaced with a new bushing and debris screen.When you disassemble your tool you will discard your 6-vane rotor and inspect the cylinder for pits and deeps scratches and grooves. The rear end plate is then refurbished to remove scratches caused by dirt scraping rotor wear. Refurbishment of this end plate is done carefully and with the least amount of material removed to smooth the wear pattern uniformly without losing the parallel surfaces on the end plate. This is where live contact with me for help will come into play. This 8-vane conversion kit makes your new rotor free floating inside the air motor. Having a proper understanding of what needs to be done is why I am offering my help here. Professional technicians doing air tool repair daily know what to do here. DIY mechanics and weekend warriors should not hesitate to contact me for any particulars or questions that they may have with this conversion kit OR anything else they want to buy from me or are thinking of buying from me. I answer all of my inquiries with either email through eBay or phone communications through the "contact seller" portal. Make sure your buyer contact information is current before checkout is completed on eBay if you want me to contact you. Having old disconnected phone numbers or phones that disconnect me or go to voicemail are not my problem to contend with.**Note..Before your conversion is attempted consider full teardown and preliminary inspection of your IM6100 and IM6500HP. Proceed with this purchase when you know conditions are right. I am not in the business of taking returns when or because you encounter costly problems. Choose carefully and choose wisely knowing you have the right conditions for this conversion kit to work successfully. If after this conversion is done and your tool is still taking more effort than you would like to loosen fasteners then look at these items: engagement dogs, anvil flanks where the dogs are contacted, hammer pins and hammer frames for damage or wear. A broken or cracked hammer frame means you are probably starved for air to your tool and after a tune up have air hose issues or are a serial tool abuser who is too cheap to buy a 3/4" drive impact wrench. Hammer frames will break from tool abuse caused by worn out engagement dogs and worn out rotor vanes.I am here to help with this conversion kit. Proper installation, tool maintenance and air pressure requirements are 100% completely your responsibility to oversee before you blame me for any of your issues with my kit. The shipping weight is 1 pound with an ebay USPS.com Priority Mail flat rate envelope, insurance and tracking. International buyers have this item shipped to Glendale Heights, Illinois for additional processing costs through the eBay Global Shipping Program.
