Lin; figure 3 to 5 hrs depending on what has to be removed to reach both sides the toll volition depend on the rate of the shop

have a great day

Make sure the easily-on mechanic actually knows what he is doing. 4 years ago when I first got my bus and didn't know much about Detroits, I took information technology to a DD dealer where they inverse 2 injectors and ran the rack. A young tech. did it with an older guy coaching him from a distance. They notwithstanding charged me the shop rate of over $100/hr. Information technology ran good enough I thought, although I've had increasing problem with it since. Lately information technology wasn't running good at all, so I got into it myself and plant one injector that was merely going to half fuel and another one where the control finger on the tube was loose and not moving the injector rack at all. So I "ran the rack" myself, following the instructions in the DD service manual and got an immense comeback. It runs better than ever, smooth, snappy with lots of power, (for a 4-71). Running the rack is actually non that hard. Information technology takes some patience, a sensitive touch and a love of your bus! Study the book outset and then you sympathise what goes on in the governor, the fuel control tube and the injector racks. The object is to have the control tube moving all the racks to full fuel every bit without binding. It is not as hard equally information technology sounds, even for a half a mechanic similar myself. So there is the saticfaction of accomplishing this yourself, as opposed to giving a store $500.

Lin, if you accept Jake's it would be all-time to permit a DD guy run the rack information technology's non easy to exercise with Jake's in place.How far do you alive from Needles CA one of the all-time ii stroke wrench's around has a shop at that place has several sets of complete Jake'due south besides if yous need a set.   practiced luck

My engine has jakes and I didn't find they were in the mode. The only reason to remove them would be to replace an injector. And even that doesn't look also bad.

Lin, are you into doing it yourself, or having it done? Make certain you lot go a good, experienced mechanic that will care to do a good chore if you are going to spend the money.

I had a steering column installed by a local mechanic.  I'grand pretty happy with the mode that'southward come out, and he did a couple of other small stuff.  I asked him about running the rack.  He really didn't seem that he wanted to practise it.  He is a big, wide guy, and I don't think he likes the idea of squeezing into the back, so he said it would have ten-12 hours.  It do not think that it is critical but believe I will go some improvement from things existence set right.  I volition wait at the book and see if it is something I wish to try, simply probably would like to know it is done right instead.

Needles is about 160 miles from me, so it is something worth considering.  Maybe, after it cools down a little, we could encounter about a trip that way.  Please requite me the info on the mechanic there.  What are his rates like?  I do not have a Jake, but I am not sure I need one at present since I accept a Spicer and tin can only go down hills slowly.

Lin, it is A&A Diesel Service  928-768-4311  (ANDY)I see he has a AZ number now.If you come this way I have 50amp service and you are welcome to spend the dark and and I would fifty-fifty throw something on the BBQ or you could take in the casinos and food  forgot he was charging $65.00 per hr  practiced luck

Lin,

Don Fairchild in Bakersfield is a DD whiz and he loves them. I know it may be farther than Needles but doesn't hurt to take more options.

Thanks,
     Either trip is worth considering when I determine to finally get it washed.  I've got a collection of things I desire to exercise with information technology at dwelling first.  I guess information technology will be Oct/Nov when we get to it.  I've copied the info.

I watched racks beingness set upwardly on 353 and 453 Detroits, only that was long ago and I take totally forgotten how. 35 years by.

Could we learn such a fun, new skill today?  If I had a 2-stroke Detroit, (which I don't) would I learn how?  Dunno.

Usa one-time coots used to fix the valves on our 283's with solids.  Why not learn how to set Detroit racks, have fun and goof off?

I agree that it would be fun to learn.  It's sort of like studying calculus.  Even if you lot don't utilise it and forget information technology pretty soon, you can add it to your list of life accomplishments.  You could fifty-fifty spice conversations with information technology like, "I retrieve the time I ran the rack on my 8v71."  All the same, past learning how to do information technology, I practise not hateful I want to start blindly pulling things apart in my driveway without a clue about where I'yard going.  Ideally, I gauge I would like to do information technology the first fourth dimension as a helper.  If I am to experiment, it would probably be improve on someone else motorbus.

Every bit I said in a higher place, it is not witchcraft. Anybody with a minimum of mechanical aptitude and the willingness to learn can do it. I like those old two stroke DDs, and equally with everything I own, I have to go familiar with them, so I tin keep them tuned upwards and running correct anytime equally needed.  You first read the manual, then you lot do information technology one first time, then the second time y'all practice it that much better, by the third time, you're really good at it. As the quondam generation two stroke DD mechanics are getting rare, we take better learn to do it ourselves. And yes, there always volition be nay sayers who say it can't be washed by anybody but a seasoned old tech. with 40 years experience. As for myself, I tin acquire anything if I put my eye into it. We should get some of these erstwhile mechanics to give us a seminar on how to tune up a 2 stoke. Now there is an idea for a bus rally...
