I can't find any info on YM 1110D parts for an engine rebuild. From online info the 1100 and 1110 tractor are 11 HP...
The 2T72 uses these parts,
YM1110 2T72, Y-124901-22090 Piston Kit, 72mm P20 C30mm
(same piston in the YM1401, Piston 72mm TW 46 1401 F15 (flat)
Buy the ring-set for the YM1401. You will have one extra set.
The rings fit these models too, YM1110, YM1401, YM1510, YM1502, F15
Even download these manuals from the YTOG to verify the part numbers.
YM1110 2T72, Y-2T72-15, Engine Block Liner/Sleeve 72mm (Finished/Polished) TW
(same liner as the 3T72 engine, ΥM1401, Y-3Τ72-15)
* NOTE, the 2T73 engine liners are DIFFERENT.
Notice the TW at the end of this Yanmar listing. The OE for the liners Yanmar has used for the past 60 years is,
YM1110 2T72, Y-2T72-2, Head Gasket, 2T72 (2GM20F Marine engine variant)
OR ...
YM1110 2T72, Y-2T72-4, Full gasket engine kit complete
To play it safe, it would be wise to download the Parts Manuals for the models with the 3T72 engines. Compare the 2T72 part numbers with those part numbers in the other manuals. Then sleuth out the details of where to get the parts.
Weavers has a large PDF downloadable Yanmar parts catalog for the Gray Market machines.
The Yanmar genset with the 2T72 engine is the AG8S model if you go searching for engine kits that way too.
Just giving you options.
