Would anyone happen to have a page or two on how to set up the governor to run the rack? What is the injector height?

I have an overhaul manual for 53 Series, injector height is determined by type of piston and type of injector along with gear train timing. Do you have trunk type pistons, crosshead pistons, turbo charged or non-turbo'd. Some use N45 or N 50 injectors .
Some use a whole bunch of different injectors for turbocharged trunk type piston versus crosshead pistons.
I do not have the parts book so determine by piston type and design of engine.
Better post more information, and if you have never set the governor linkage including the idle and buffer screw, be aware that in 3 seconds the motor will be grenading if not 100 % and injectors stay full fuel.
Good idea to find an old guy who did lots of them, and if the peerson does not know what the vise grip pliers are for just run and don't look back. Any seasoned 53 mechanic knows what they are for. But each to their own.

Heavy on the vise grips, most of time it can be seen where used before on rack.

Need 2 pairs if it is a V-block, one for each side. Only thing that can help unstuck an injector in full fuel with engine running away. Blower flap is not guaranteed, and have seen from experience.

Big trucks is what I know. HAZMAT is what I tow.
It’s one of those procedures that can’t adequately be written down. There isn’t words in our language to describe it. Despite whatever level of reading comprehension. It can only be shown. Once you see it, then written prose makes more sense.

I am the old guy but the last one I turned a screw on was an 8V 92 about 20 years ago. Only books I have are for 92 and 71 series. I AINT SKERT!
Have about 6 height pins but none are close to where these are set. That tag is all the info I have and the injectors are 60's as per the tag.
All advice and sharing from your manual is greatly appreciated!

A man named Grady and Kennedy helped me years ago. Grady was not much on reading but he knew 2 stroke Detroits large and small. I understand what you mean and agree. Words also cannot explain what one sounds like in 3 seconds as well. I watched around the corner of a shop door when Kennedy shut one down. Person that started ran like hell.

So You have 5E60 Injectors according to your tag on the valve cover. Is it a aluminum valve cover with a one piece silicone seal. The book in front of me shows that injector for cross head pistons. So the correct injector height is suppose to be 1.480 for a 3-53T.
Your engine will have smaller pulleys in the front compared to trunk type piston engines. The reason I said that is because some guys changed over to the new non-leak valve covers with old trunk type pistons.
A couple good pictures would tell a lot.
I have all the tools for tune up and governor adjustment along with the special piston pin tool.
Any more questions.

It is an aluminum valve cover with small pulleys and spin on filters. Looks like a late production engine to me. Army surplus that looks like an all original low hour unit. It is too far away for pictures but the last two injectors came in today.
They could not get it to start after a vacation. I put an electric fuel pump on the engine supply line to prime it. It had two fuel leaks on the lines before the pump. Repaired those, ran and removed electric pump. It would not start. Tried some starting fluid. Pulled the valve cover and found an injector plunger stuck down. Replaced that injector. Planed to sneak it in without messing with everything else. Found the other two injectors control rods not behaving properly and ordered two more injectors.
Will start from the beginning daylight 30 Thursday?
THANK YOU SIMON!

Hope you used a torque wrench on the injector hold down clamp as the correct torque is a tensioning of the hold down. Those should have spring back style fuel racks not like the rigid type ones.
The last 53's built lasted quite well in the days I worked on them and were not leakers either.
I am guessing that you have a double weight limiting speed governor, not a variable speed unit.
What kind of machine is it in, skidder or forklift, or crane.

Torque wrench box was empty. Working on too many things at the same time. It was under a truck at the shop. I will double check it. It is a spring style rack. Limiting speed - yes. It is in a trencher. Someone stole the wheel off a grist mill and hooked up to a Detroit to dig ditches. I will get you a picture.
