giacomo.m Posted May 12, 2017 Share Posted May 12, 2017 Hi all, I'm replacing timing belt on Defender 200 Tdi but I have problems on fitting the belt ,seems to be short, since the tensioner is very difficult to move Is there any trick to adopt ? thank you Giacomo Quote Link to comment Share on other sites More sharing options...
western Posted May 12, 2017 Share Posted May 12, 2017 I remove the tensioner, slip the belt on, then refit the tensioner leaving the bolt loose, once it's back in place & correctly seated then the adjustment & tension of the timing belt & torque up of the tensioner bolt can be done 2 Quote Link to comment Share on other sites More sharing options...
Snagger Posted May 13, 2017 Share Posted May 13, 2017 Good suggestion, Ralph, or at least remove one of the fixings for the tensioner completely to allow the back plate to swivel enough to get the belt on easily. It can be a pig of a job with the tensioner slackened but both fixings in place. Quote Link to comment Share on other sites More sharing options...

western Posted May 13, 2017 Share Posted May 13, 2017 94489 Dayco is the same as I fit, the tensioner only has the one long bolt through the entre slotted washer, the other round hole fits on the timing case spigot & the 1/2 inch square hole for the tensioning torque wrench to fit into. haven't had any trouble tensioning mine, IIRC a new belt is tensioned to 17Nm, then the tensioner bolt is fully ttorque tightened.

giacomo.m Posted May 13, 2017 Author Share Posted May 13, 2017 I agree 100% with what you say, but once assembled I feel it is already tense so it does not let me tensioning it to 20 Nm Giacomo Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted May 13, 2017 Share Posted May 13, 2017 Have you slackened the 3 bolts on the fuel injection pump pulley ? If you don't it makes the belt really tight. Mo Quote Link to comment Share on other sites More sharing options...
giacomo.m Posted May 13, 2017 Author Share Posted May 13, 2017 Yes, i have slackened the 3 bolts Giacomo Quote Link to comment Share on other sites More sharing options...
western Posted May 13, 2017 Share Posted May 13, 2017 that 20Nm is to high, it needs to be 17 nm for a new belt, it is a tight fit, Quote Link to comment Share on other sites More sharing options...
