I am just about ready to install the pan but I need a little convincing before going further on the 14mm tripple square.
The B5 balance shaft module write-up indicates the 14mm triple square intermediate gear bolt should be torque to 15 ft-lb (20 Nm) + ¼ turn of stretch. At just under an 1/8 turn Im over 50 ft*lbs. It feels real solid. Is this nromal? I am afraid to go further in fear of making $1200 mistake.
Does anyone recall the having same concern?
Any idea what rough torque is at ¼ turn for this bolt?
Stretch bolts can be a bit freaky with the amount of pressure you sometimes need to put on them in my opinion. I hate that feeling where you think it feels like it's just gonna snap off but it needs to go further.anic:
More so, good on you for doing the Balance shaft replacement. :nana2: I went through that ordeal a couple months ago. While your under there, don't forget to service your transmission.
greybear,
Thanks for the encouragement on the transmission. I could easily get distracted by the 06 Jetta cam and flywheel job ahead.
Did your balance shaft module fail or just make a lot of noise?
In my case the chain, sprocket & slides did not look bad at 120,000. The chain sound disturbed me and considering the effort needed to inspect the BSM I did it as a preventive measure along with the cam replacement. The floating slide had about 4 to 6 divot like imperfections about 1-3mm spherical. The Sprocket and chain looked very good. The chain sound is gone. The TDI has nice sound now.
For the cam the worst lobe was about .040” shorter than the 3 good ones. The lifter has dished ring developing. VW considers this normal wear because it still runs.
