Stus-List Engine Troubles Injector Rebuild
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 Mine were sticking / cold start was smoky and sometimes laborious. I have shopped for / seen them for less in the past. I can postpone that purchase now.. With a steady diet of Power Kleen and regular once a week use (or more) thanks for Wed nite racing. It's pretty much cured: It cold starts in 2-3 secs with the throttle on idle. (It used to refuse to start on anything less than full throttle / several minutes of cranking) Regards -Francois Rivard 1990 34+ 'Take Five Lake Lanier, GA ___ Email address: CnC-List@cnc-list.com To change your list preferences, including unsubscribing -- go to the bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com
Re: Stus-List Engine Troubles Injector Rebuild
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 CC 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?

Re: Stus-List Engine Troubles Injector Rebuild
Mike, I also have a 3GM30F and at the time [2010] the work on the head gasket and injectors was done the engine was ~ 25 yo, 12 of which I had been the owner. Was getting quite a bit soot on the transom, cold starts were becoming increasingly difficult and the idle was rough. As I had never done any major work on the engine and since the head was pulled and sent to a machine shop to be reconditioned, the mechanic recommended having the injectors sent out to a shop to be rebuilt, rightly concluding the “spray pattern” was not optimal. It took about a week + but part of that time was due to the injector shop owner had recently passed away and his widow was doing the work, without all the “certified training.” The injectors had to be redone. The mechanic also adjusted the valves so everything was back in spec. Pulling just the injectors did not appear to be an overly complicated process. The injector rebuild itself included replacing the nozzles and was US$125 for each injector. The total hours billed included a few other repairs / replacements so would estimate the labor for the injectors themselves were ~ 3 hours all in. Add in a few other minor parts like copper washers.
