Check the listing for details. SNAP ON XT7100 TUNE UP KIT WITH BEARINGS, SPRINGS AND REVERSE VALVE DETENT BALLS. Condition: New other (see details). Listed at 59.00 USD. This ebay Buy-It-Now offering provides all the above shown parts to tune up and field repair your Snap on XT7100 1/2" drive impact wrench. You cannot buy this kit from Snap on and you cannot find somebody else on the internet offering this kit. It is unique and custom designed by me. Snap on Tools no longer supports making repair parts for the XT7100 tool. I still stock some clean used parts and make new high quality anvils for the tool all done right here in the USA.SERVICE NOTES The regulator valve inside the forward/reverse valve body has a small o'ring. This o'ring is not shown on any Snap on diagrams. A snap ring retains it and must be exercised to pull the regulator and change the small o'ring. A new snap ring is provided in this tune up kit along with new detent springs and steel balls.2 ounces of: ATF, 30 wt. non-detergent or light motor oil should be installed inside the hammer frame end of the tool housing. If your tool anvil has a rough edge on the seal journal for the front oil seal and holding oil won't work use black moly grease instead of oil for the hammer case end of the tool. Ingersoll Rand uses grease on their hammer case parts and it seems to work well. Any other questions just email me. The four large o'rings are sized correctly based on the housing diameters. Small o'ring to the front end plate. 2 medium sized o'rings to the cylinder. Largest o'ring to the rear end plate. Light oil, vaseline or grease for installation. This is different from Snap on because they use the same o'rings on 3 different parts. There are many errors that have never been corrected by Snap on with their tool drawings. I have have had to learn this quickly and have corrected their mistakes by updating this kit. Provided in this lot are as shown above and stated below: ME6A29............as item 1, the front seal. ME7A97............as item 3a, the 1/2" drive anvil socket retaining ring. ME7B3..............as item 3b, o'ring 1 black. ME11A48..........as item 7, the front rotor support bearing. ME6A35............as item 8, the air motor oil seal. ME7B91............as item 9, the o'ring for the front air motor end plate. This is the smallest of the (4) o'rings in this kit. XT7100-30-9V...as item 11, the 9 vane rotor set for this tool. ME7B16J...........as item 13, the (2) medium-sized air motor cylinder body o'rings. *Special note.....the o'ring needed for the rear end plate is the largest o'ring of the (4) supplied with this kit. The largest o'ring groove plate diameter calls for a larger o'ring than Snap on dictates. I have purchased several XT7100 tools for parts and looked carefully at this o'ring application in making this statement. ME11A46...........as item 17, the rear rotor support bearing. XT7100-3..........as item 18, the rear cover gasket. ME7A211...........as item 22, the reverse valve retaining ring. BLACK O'RING....as item 23A, the regulator spool o'ring seal. Not shown in above print. IM6100-22.........as item 31, the throttle valve seat. Now obsolete from Snap On. I substitute the valve seat from the IM3100 which fits perfectly and does not require special orientation with the raised tang. IM6500HP20......as item 32, the trigger valve. This part is now obsolete from Snap On with no suitable replacement that looks exactly like the original design. I supply the IM3100 trigger valve with a straight stem. This is easy to install and fits perfectly. It also seals well and operates without any issues. ME1A226...........as item 33, a trigger valve spring, or throttle valve spring. ME7B68.............as item 35a, the air inlet adapter bushing o'ring. The shipping weight is 4 ounces with an eBay USPS Ground Advantage shipping label and tracking. International orders ship to Glendale Heights, Illinois where the eBay Global Shipping Program takes over to finish the documentation and final delivery.
