engine bolt torque values
« on: September 24, 2024, 01:45:46 PM »
Hi
I'm rebuilding a 1971 Beta 2000 engine, and I've searched, but can't find the torque settings for conrod bolts, main bearing nuts, head bolts, cambox bolts etc.

Even the Workshop Manual I downloaded doesn't have them.

Can somebody point me to a list, please?

There is a Beta Technical Book the LMC Librarian can sell you cheaply. Also any of the Guy Croft Workshop manuals will give you the settings and tell you if threads should be dry washers lubricated etc. There is also a Haynes Beta Manual which will give you settings. Do read on here about head gaskets and bolts. Do NOT re-use head bolts and DO clean the threads in the block for example.

Many thanks. Not a great truster of Haynes, but the other refs seem sound

Hi Bob

I assume you mean 1981 engine…?
