Hi Guys,

Say does anyone out there know which number water pump might be on the Yanmars 20 KW Gen. that were produced back around 1999. I call two different Yanmar distributors in different parts of the country and they both said they thought it was the same number. So I went on eBay and bought it but after receiving it I noted that it wasn't even close. From what I understand is for that particular diesel motor they made like six different water pumps for it depending on what it was being put into (ie; boat, gen., bulldoser, bobcat, etc.).
I checked with my local RV mechanic and he can't find it through his sources, I've even put in 2 calls to Newell parts but they haven't gotten back to me for quit a while as of yet and they may not know for sure either.
If anyone out there thinks they know please get in touch, thanks!

Chris,

Your engine has a model number such as 4TNE84T-RKRV.  You’ll need this since as you have found out, there are a number of different configurations.  With your M/N in hand , call Martin Diesel in Defiance Ohio 419-782-1198 and navigate to the parts department.  They will help you.
