It is anyhow necessary to also check the seals of all
main components and their surface contact, such as:
- crankcase and oil seal (side 1
a
PTO)
- oil sump and exhaust caps

It is also necessary to check for leakages on the components
that are not listed.
If necessary, disassemble the components that have a leakage
and investigate the possible cause.
The components must be replaced otherwise they do not
guarantee their sealing.
