Crankcase lower section fasteners. Reusable?

[bebbetufs]

I have asked this before but I got no definite answerdue to the nature of that thread. So I'll try again here.

When removing and reinstalling the lower section of the crankcase. Do I need to buy new nuts and bolt or are they reusable? I cannot work this out from the manual or the parts catalogue. Someone told me I could reuse the nuts and washers but I shold replace the bolts.

What is the sensible thing to do when on a budget?

Almost all of the nuts and bolts on the engine are reusable.

The only non-reusable nuts and bolts on an engine rebuild are the smooth conrod nuts from the early cars and the bolts attaching the flywheel to the crankshaft.
