Anybody have issues with Snap-ons MG-31 3/8 impact gun? I had to send it back to S/O a week after I bought it for a reseal. This was back in 08. Okay I have only used it a hand full of times since then as I switched to cordless impacts. But now it blows all kinds of lube out of it I think it still hits hard but can't remember what it felt like new. Is this common with this model? Would S/O honor it and fix it or am I screwed? Thanks y'all.
Front end of this wrench is sealed with oil inside. This is the hammer assembly.
I usually immerse the tool in water just to above the trigger with the air turned
Down to about 40# and see what happens. Some leakage around the trigger bushing
Is normal and maybe a tiny bit from reversing valve.
A seal up front and a couple o rings should take care of any problem shy of a cracked housing. Be sure to dry gently with hair dryer before storage.
Also, after much experimenting I use synthetic ATF about 3/4 to top of cup inside front end.
I think any clean oil will do on a pinch. Bearings and bushings in any tool must be kept
Wet with oil of some kind.
Please note this is just my opinion"...
