Torque specification
I am trying to for the torque specifications for the oil pan bolts and haven’t found anything. That made me think about it and I don’t remember seeing any on any part of a cub. Is there a place that has that info?

Re: Torque specification
Try this Blue Ribbon Manual from the links above:
CUB INFO>RUDI'S MANUALS>BLUE RIBBON SERVICE MANUALS>SPECIFICATIONS>ENGINE NUT AND BOLT TORQUE SPECS
or:
http://farmallcub.com/rudi_cub/www.cleancomputes.com/Cub/Blue%20Ribbon%20Service%20Manuals/GSS-1008%20Specifications/GSS-1008%20Specifications.htm
Just make sure you get those rear bolts tight, but don't strip the holes. Those rear bolts screw into the softer metal of the Rear Engine Seal Retainer, which is easy to strip, and would need to be helicoiled if that happened.

Re: Torque specification
Hi,
The Cub service manual has torques for some bolts, below is the page.
http://www.farmallcub.info/manuals/gss- ... 001-09.jpg
If a bolt is not listed specifically, use the table below. It is made for modern bolts, with modern head markings. That is shown at the lower right of the page.

Re: Torque specification
I noticed that the Oil Pan was not actually listed, but this earlier post by Glen should help you:

Re: Torque specification
Looking over the list I may have slightly over torqued them. I only used a short 8” socket wrench but I made them a little over snug. Sure I could still crank down more but I don’t think they needed more and I’m glad I didn’t. By the way, what is a good way to get to the middle back bolt? I used a U-joint adapter to swivel it and a thin extension but I’m not sure how to really get to it well without splitting the tractor.

Re: Torque specification
I bought a Swivel 1/4" drive SHALLOW 1/2" socket that I used with a 1/4" ratchet + an extension. It's still a bit difficult, but works better thank anything else I had. Not sure of the brand, but it is similar to this:

Re: Torque specification
It is my opinion that the oil pan bolts are usually over tightened by most. What happens, in my view, is the tightened bolt squeezes down the pan gasket at the bolt location and can make gaps between the bolts causing leaks. I feel the best thing to do is flatten out the pan flange as good as you can get it, put a good sealer on the gasket and add Locktite to the bolts. Just get the bolts good and snug, not cranked down.
If you check the flatness of the oil pan flange, you'll likely see distortion of the flange from previous over tightening.

Re: Torque specification
I like to use a nut driver for tightening gasket bolts not subject to pressurized liquids, i.e. gravity drain. You can get them snug, but not distort or crush the gasket, causing a potential leak, like is possible using a ratchet or power tool to tighten, since you do not have near the leverage. In these cases, normally a good thing.
