I found that some Yanmar parts are readily available at Tractor Supply stores. For example, using the Yanmar part number (724770-53100) in the Hoye Tractor search field I found the following 3QM30 injectors cross listed to IA-4770 for $118. See http://www.hoyetractor.com/PROD/search/IA-4770.htm <http://www.hoyetractor.com/PROD/search/IA-4770.htm>
I saved over $600 buying 3 new injector pre-combustion chambers. Mastry Yanmar wanted nearly $300 per cylinder, I got them for about $60 per cylinder at Hoye. I did not buy new injectors, I brought my injector pump and injectors to a Diesel shop. They rebuilt the pump for about $200, and tested the injectors(no charge). The injectors were fine. The place I went to was called Shiver Diesel Injection just outside of Tallahassee, and since we have a diesel injection shop out at no-where-ville, I’m guessing there’s a similar place near you. - Paul E. 1981 C&C Landfall 38 S/V Johanna Rose Carrabelle, FL > On Jun 22, 2015, at 2:45 PM, cnc-list-requ...@cnc-list.com wrote: > > Date: Mon, 22 Jun 2015 12:29:35 -0400 > From: "Jean-Francois J Rivard" <jfriv...@us.ibm.com > <mailto:jfriv...@us.ibm.com>> > To: cnc-list@cnc-list.com <mailto:cnc-list@cnc-list.com> > Subject: Stus-List Engine Troubles > Injector Rebuild > Message-ID: <201506221630.t5mgucr2023...@d03av05.boulder.ibm.com > <mailto:201506221630.t5mgucr2023...@d03av05.boulder.ibm.com>> > Content-Type: text/plain; charset="us-ascii" > > Here's another option: Instead of paying 125.00 per for rebuild why not > buy brand new ones for 132.00 bucks each? > > See here: > http://www.ebay.com/itm/Yanmar-1GM-2GM-3GM-Injector-NEW-Part-728170-53100-FREE-SHIPPING-/151718415253 > > <http://www.ebay.com/itm/Yanmar-1GM-2GM-3GM-Injector-NEW-Part-728170-53100-FREE-SHIPPING-/151718415253> > > Mine were sticking / cold start was smoky and sometimes laborious.
