Your balancer, re-tighten after you use it for a while. Robbie was going to have me pin it after it came loose after using the air a few times! After re-tightening haven't had an issue since and I didn't have to pin but doesn't hurt either!
On your PSC pump did you use the idler they suggest and is in there kit or the stock Jeep one? I am doing the same setup just haven't made time so wondering about the belt I need?
I put on Tom Wood DS front and rear and with the adapter Robbie sent, not sure if it was the shorter one, the rear just barely worked with stock arms and front had to be sent back in and lengthened 2.5". If I would of waited instead of pre ordering the DS for stock dimensions I would of not had this problem!
It didn't help I moved everything back as close to the fire wall as possible and didn't have to move the radiator to accommodate! Maybe 1\4" between fan spal and water pump idler but it worked! If you have fat fingers and ever need to get at the back of motor this will not work for you and you should still use Robbie's dimensions anyway to get close!!! My skinny hands come out bloody and the molded ground stud on back of drivers side head is rubbing heat and noise shield slightly so it is back there!! Like Robbie said you have play and you can move the body back some, 1\2" or so, if you push it back against bolts when mounting. I did mine with body on so checking it several times before welding in mounts permanently was possible!
If you have a question put out a shout! There are many and the number is rising that have done this at home! There are some gotcha's but walk away when you hit a snag and keep it fun! Otherwise you will get the C4 and give up! A lot to learn and you will NEVER know it all even though Robbie seems to be close at times!!!
I don't know how he does it with all that he has going on! With family and a small side business I don't get the sleep I need!! He has to have a small Army of Special Minion's to help keep ahead because I have done my fair share of bugging him!!
