I was checking over the 3 banger Isuzu engine (3AB1) while it was idling and notice the linkage was abit sloppy, bolts had backed off and the linkage was sloppy. I went back to the cab and pushed the throttle forward as far as it would go and then went back to the engine and saw that the linkage wasn't tight on the injector pump, so i slowly pushed it forward up against the stop bolt and got more revs. Should i adjust this linkage so its tight right away or just do it over a longer perod of time. I'm not sure how long its been like this and a little concern about the ridge on the top of the liners. Maybe i should leave well enough alone. Thanks

    How many revs you talking about?

    Not really to sure probably sounds like the machine runs around 18 to 19 and when i push it to the stop bolt it must be around 21 to 22 maybe 2300 rpm. I gotta get a tach instrutment i guess.

    nah you'll be fine you dont need a tach.....rap 'er on up to the bump stops on the pump if its just the linkage thats loose....they prolly have a high idle stop on the pump somewhere in the linkage directly on the pump Pj

    That's all good, unless someone has messed with the high idle stop.

    Powerjoke, what does mean i have heard and used a few expressions like that before, but out west its either half full or half empty i guess the phrase got lost in translation going east rockies and totally confused by time it reached your neck of the woods. So what ever you do don't try to repeat this to anybody you; don't know or can ran faster than you. If a donkey is an ass and a goat is a ram is a ram up the ass a goose. cheers
