astrindi Posted October 14, 2019 Share Posted October 14, 2019 Hi all, I have recently replaced timing belt on my 1998 300tdi defender. I replaced belt, tensioner, idler pulley and crankshaft gear. Followed instructions according to enlosed pictures. Doublechecked against factory workshop manual and even the Haynes manual. 🙂 FIP and flywheel locked at TDC with no problems. After new belt was fitted and tensioned, I rotated crankshaft two turns to TDC, locked FIP  and flywheel and tensioned timing belt again to 11 Nm. Did it one more extra time just to be shure. Then mounted front cover with new gasket, refitted crank pulley and mounted new drivebelt. Then I tried to start it up for a few seconds. No luck... Drive belt moved 4-5 inches but nothing more. It sounded and felt like the engine didn´t had enough power to start. Just as if you were trying to start in very, very cold conditions. Did the whole procedure again and double checked everything was aligned and locked at TDC. No problems. Reassembled everything again up to drive belt and tried to start. No luck this time either. Now there is a rattling sound (machinegun-like) when i try to start. Nothing moves, not even the drive belt. I cannot figure out what is wrong. It feels like I´ve missed something obvious. Any of you guys out there have an idea what might be wrong? Have you ever had the starting problems I describe above? Thank´s in advance!    Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted October 14, 2019 Share Posted October 14, 2019 Assuming all timing pins etc. have been removed, a battery perhaps? Does the engine still turn over by hand okay? Quote Link to comment Share on other sites More sharing options...
Gazzar Posted October 14, 2019 Share Posted October 14, 2019 Did you disconnect an earth strap? My TDI has a strap from the battery to the timing case. Quote Link to comment Share on other sites More sharing options...
monkie Posted October 14, 2019 Share Posted October 14, 2019 Is the noise you describe like a fast clicking? If so it could be the starter solenoid because not enough power to the starter. Put the battery on charge and check the connections as above including the nut on the starter positive terminal to ensure nothing is loose. Quote Link to comment Share on other sites More sharing options...

Does the engine still turn over by hand okay? When turning crankshaft bolt it feels as it did before i removed the old timing belt: partly it turns easily and partly it´s hard to turn. Checked battery and I remembered to reconnect the battery. 🙂 Thank´s for your help! Edited October 14, 2019 by astrindi Quote Link to comment Share on other sites More sharing options...

No not that I can recall. But I will definetly check the earth strap to see if anything is loose! Thank´s for your help BTW. 🙂 Quote Link to comment Share on other sites More sharing options...
Gazzar Posted October 14, 2019 Share Posted October 14, 2019 If you can turn with a socket on the pulley, but not with the starter. It's the starter system. Quote Link to comment Share on other sites More sharing options...

Thank´s, will check as soon as I get home. Quote Link to comment Share on other sites More sharing options...

Why didn´t I think of that! :-D As I said before, feels like I´ve missed something obvious. I´ll keep my fingers crossed and will troubleshoot focusing on the starter system. Many thank´s! I´ll post an update here with the results. Quote Link to comment Share on other sites More sharing options...
