randyp Posted September 10, 2009 Share Posted September 10, 2009 Anybody got any advice on changing belt tensioner on cummins 6-BT on Komatsu dozer. The idler is pressed on and tensioner and idler are changed as one unit. Do i need to relieve tension with bolt in middle of tensioner? It looks like it bolts to brace but head of bolt is under plastic cover on front of tensioner, any advice is appreciated, eating belts, idler bearing is out, and im not a very strong person and dont want to wear tensioner home on my forehead,,,,randy Quote Link to comment https://www.bigmacktrucks.com/topic/10605-confounded-belt-tensioners/ Share on other sites More sharing options...
