General Information
This Chapter gives information about specifications and
repair of the diesel engine used in the Groundsmaster
4100--D and 4110--D.
General maintenance procedures are described in your
Operator ’s Manual. Information on engine troubleshoot-
ing, testing, disassembly and reassembly is identified in
the Yanmar Service Manual.
Most repairs and adjustments require tools which are
commonly available in many service shops. Special
tools are described in the Yanmar Service Manual. The
use of some specialized test equipment is explained.
However, the cost of the test equipment and the special-
ized nature of some repairs may dictate that the work be
done at an engine repair facility.
Service and repair parts for Yanmar engines are sup-
plied through your Authorized Toro Distributor. If no
parts list is available, be prepared to provide your distrib -
utor with the Toro model and serial number of your ma-
chine.
