John Deere 318 - Manual (Page 115)

IMPORTANT: If replacement gasket is made of rubber
coated laminated metal, clean mating
surfaces of differential case and cover
and install gasket. Do not apply
sealant. It will cause oil to leak.
If replacement gasket is made of paper,
clean mating surfaces of differential
case and cover, apply recommended
sealant, then install gasket.
23. Clean the mating surfaces of differential case and
cover using Clean and Cure Primer. Apply a coat of
Flexible Sealant or an equivalent to differential cover and
case when using paper gasket only.
24. Install gasket, cover, and 13 cap screws. Install cap
screws finger-tight.
25. Drive two dowel pins into differential cover.
26. Tighten cap screws to 23 N·m (204 lb-in.).
