Oil pan

[GearHead]

Hey guys, replacing the gasket for my oil pan. Can?t find much for torque specs.
its an 1982 gs850glz. Does anyone know the order and torque specifications for the bolts ?

For the order of tightening, you can use the valve cover or head sequence as a general guide for most planar surfaces...

In the shop manual, these aren't specifically mentioned BUT goto page 402 where there's a chart for non-specified bolts...

Ididn't look up the bolt size but guessing it's one of these:
For 6mm bolts without a topmark or a "4",torque is 3-5 ft/lb (topmark7 is 6-8.5)
For 8mm bolts without a topmark or a "4" torque is 7-11.5 ft/lb (topmark 7 is 1.8-2.8)

don't use a big torque wrench -I don't consider these or similar tools to be accurate at their lowest setting-use a small one that indicates inch/ lbs so that your setting is in the middle of settings.

Multiply "ft/lbs" x12 for "inch/lbs" Or use the metric

If you don't have this manual, look for it at

Pans and covers are flexible. Think flattening a sheet of paper on a table.
Start from the middle and work to the edges in criss cross pattern leaving the corners last.
Here is the parts fiche

Parts 3 and 4 are 6mm diameter and 30mm and 25mm long respectively.
Look at the last four digits in the p/n. -6258 means 6mm x 25 long. Don't ask what the 8 is?
Check the screws you have, don't assume what came out is right.
If a long screw goes into a short hole it can bottom out but not enough to notice and it can leak.
Unless you have a torque wrench of the right range for these small things it's better to go by feel.
Using a large tool at the very bottom of it's range is not a good idea.
It's all to easy to get fixated on the tool and strip threads.
