This is the recommended replacement frequency. It may be a conservative value. Some
owners replace the chain less often, or only when it becomes noisy. In doing so, they rely on the
tendency for a chain to wear and become slightly elongated (hence the noise). They also rely on their
ability to distinguish chain noise above other engine noises. However, this approach is not entirely risk
free as a sufficiently worn chain rides high on the sprockets and may jump off them, or may break, in
both cases with serious consequences for the engine. Non-expert owners would be better advised to

These data are from various sources: information provided from discussion with
those in the trade, feedback from other Delica owners, and comments on the
internet. In some cases the various sources differ, and I leave it to the reader to
decide which values to use. Much of the numerical data is sourced from trade tables
for the Pajero 4M40 engine (shown as [1] or [2]). Data from other sources is also
included.

Engine
This engine and much of the transmission is
also used in Pajero models. If you need
detailed maintenance information, e.g.
internal engine clearance, then suggest that
your mechanic look under Pajero if Delica is
not listed.
