Nolathane Mounts
I am putting nolathane mounts in place of the crappy rubber ones for the rear mounts on my Baja.
The Box is solid mounted at the front.
Only prob is i do not have any instructions and am unsure how tight to make the bolts holding the mount to the gearbox ?
Anyone know ? |

In lieu of other responses: Normal advice is to use the stock Torque setting - the torque is usually determined by the bolts themselves (specified to
keep them within their elastic range.) Increasing the torque may cause the bolts to snap, especially with the increased fatigue produced by the
stiffer mounts. New bolts would probably be a good idea, too.

Or you can use my method: tighten them until they snap, then back-off 1/4 turn.:thumb
But seriously there should be torque settings in a vw manual, or on the net somewhere. |

More Info !!
The mounts i have do not have bolts fixed to them like the standard rubber mounts. If i tighten the bolts past a point the mounts start to deform and
the washer seems to start pulling through the mount.
I expect that standard mounts could handle much higher torque as there is some steel involved as well as the rubber.
Also i expect that if you overdid the torque on normal mounts the bolts would tear from the rubber way before they snapped.:alien |

Yep, liked that one. But I remember at college watching steel samples snap at far lower stress than it is specified at - a phenomenon known as metal
fatigue...
Don't have a solid answer, but if you can get specs on the bolts you use, try tightening them to the low end of the 'elastic' range and
go from there. Contrary to a lot of amateur advice, far more problems are caused by over- rather than under- torqued bolts. If they don't come
loose and there is no evidence of "slap," they are tight enough.
