General Ike Posted March 13, 2014 Share Posted March 13, 2014 Why don't you give more specifics about the motor, the job it does and why you need more rpm. I sounds like folks are concerned about doing this.

Randy mckinney Posted March 13, 2014 Author Share Posted March 13, 2014 Its on a davey drill i have 3 of these drills all the same two of them run great this one did run great till motor blew i got a low hour used motor off a saw mill it doesnt turn enough rpm to run the compresser to blow hole out and hydro pumps dont have the pressure they did and bit rotation is slow. They run great at 2000-2100 this used motor only runs 1550 this used motor runs great just too slow.

BC Mack Posted March 13, 2014 Share Posted March 13, 2014 I certainly do know how to do what you need, but no way in heck will I write it down on a forum so you can go hurt yourself, or others.... it is a very tricky job to get right...may I suggest the following...1.. buy the official manual off ebay, you can follow the full tune up steps and confirm injector number and timing.... but you may need tools... you just don't know who was there before you... it is set at 1550 for a reason, your others seem set for 2100 which is reasonable if the injector number and timing is correct.2.. hire someone locally.... still common to find these in boats, gens and buses.3.. youtube... a scary place to learn this ART... and that's what it is.... totally experienced based.just like all the others, I caution you to go carefully.BC Mack Quote Link to comment https://www.bigmacktrucks.com/topic/35011-dertiot/#findComment-237100 Share on other sites More sharing options...

j hancock Posted March 13, 2014 Share Posted March 13, 2014 Why scrap it?Call around to find a DD guy that can look over your situation. These engines have specifications when built. He can see if there is a mechanical problem and advise you what your options are.The internet is a great place but some situations can't be solved without being there in person and really looking it all over.

Kansas farmer Posted March 13, 2014 Share Posted March 13, 2014 We had a Clark loader that was sound the same thing it just wouldn't run at a high enough rpm. We thought throttle but it turns out we had a bad injector. Put a new set in and it ran like a champ.

Randy mckinney Posted March 13, 2014 Author Share Posted March 13, 2014 The guy i got the engine off of told me he had it "de tuned" to suit his saw mill needs. Im finding all the guys around here that know detriots are in the nursing homes younger guys if u cant put a lap top to them they can work on it Quote Link to comment https://www.bigmacktrucks.com/topic/35011-dertiot/#findComment-237178 Share on other sites More sharing options...
Phase 1 Posted March 13, 2014 Share Posted March 13, 2014 Ask the guy what he did to detune it. Quote Link to comment https://www.bigmacktrucks.com/topic/35011-dertiot/#findComment-237179 Share on other sites More sharing options...
