However, if I remember correctly, the reading is a bit different than what you were used to see in PD engines (degrees between crank and cam). I believe the engine must be running for that. Try to find a measuring block with something as "start of synchronization" in it's name. So monitoring the cam/crank sync angle makes sense. Removing TB cover to inspect the TB system is not that straight forward on CR as it's on PD - much more components will need to be removed. It's 25 mm wide, as opposed to PD which is 30 mm.Īnd finally CRs have almost twice as long TB replacement intervals as PD had (120k km for early PDs and 210k km for some CRs). The belt is prone to stretching, more or less, too. Over time/miles they get worn (actually by 140k km all idlers except the large one have play and bearing noise) so free play is introduced. Valve timing in these TDIs (be it either PD or CR) is VERY important (as well as CR pump timing, opposed to what most people think/say).ĬR belt is very long (160 teeth) as opposed to PD belt (120 teeth).īesides in the TB path there are much more rollers and idlers (1 tensioner + 3 idlers on CR vs 1 tensioner + 1 idler on PD). if you have vag com this can be checked afterwards.PD injectors are also electronically controlled.
You can set it up without the dial guage but it wont be 100% and will smoke.the "start of injection" needs to be spot on really. watch the dial guage (i cant remember how much you should pre-load it (what you should see on the dial guage), you'll have to find out!) once you have the correct preload you need to hold it there and nip up the pulley. you need to fit a dial guage in the diesel pump and turn the pump slightly to pre-load the pump.
To then set up the pump belt you need to refit and tension the pump belt but dont nip up the pulley. then line the "0" up on the flywheel in the window on the bell housing. To time the cam up correctly you have to remove the pump belt pulley off the cam and slot the flat tool in. Youve changed the belt? how did you get the front crank pulley off? the center bolt is damned tight! theres the cam belt on the front of the engine and theres diesel pump belt run off the cam on the other end of the engine.if the cam belt isnt timed correctly then the diesel pump will be out too! Which belt snapped? ive done a few belt changes on these engines mostly on transporter vans tho.
