Bell housing bolts

PostPost by: davidj » Sun Feb 12, 2017 10:18 pm

Hello.
Does anyone know the torque settings for the four gearbox/bell housing bolts? I cannot find any value in the workshop manual.

Thanks in advance,

David

There are some general torque numbers provided for each bolt size in the front of the manual. If one isn't specified you can use these as default values.

Reminder be sure to seal the bottom left bolt to stop leaks from the gearbox :wink:

Morning,

Unfortunately the general torque number are missing from my manual and I don't have a FT setting on my torque wrench! I think (from memory) they are 7/16 unc. Could someone please have a look for me.

Ta,

These bolts are 3/8"-16 UNC, unfortunately I am away from my Workshop Manual so I don't know what Lotus gave as the general toque for these bolts. I was able to lay my hands on the Lotus Service Bulletin for installation of the Lotus five speed gearbox, no torque values given there!

Would the torque values be the same for a magnesium bell housing?
