Thread lock, more like super glue. Of course I put TL on it. Well not of course the first time I poulled my motor apart 2 months ago I didn't use thread lock anywhere so it's not out of the realm of possiblities, but belive after I lost my exhaust and my back plate when I had roto start I learned the importance but since then the back plate fell off of pull start that had thread lock and now the pilot shaft twice with plenty 'o' thread lock. There's got to be something bettter than hpi thread lock also I'm all out of grease I won't be buying anymore of those $2 tubes of crappy HPI TL or grease any recomendations. Also I fixed my clutchbell for the most part wit an extra washer before needle bearing thanks guys for making me brainstorm. Do any of you guys run washers under chasis wher you mount body if so what size. My chasis is starting to where a circle where I've been mounting it so many times. Now everytime I tighten down nolts the motor moves into the same place. Unfortunately the same place is not lined up good so the clutch and spur are at a slight angle. Well I'm done for the night. I figured it out in 3 days working on car I spent over 10 hours working on it and only drobe it for 20mins. Now it's dissembled and needs some more work.oh well tomorrow is a new day.
