Cummins ISX backyard overhaul questions

Motor mounts can be done with a bottle jacks and blocks. Just careful about where to jack. It's called in frame because the crank stays in the block, if you need the crank out pull the motor. The main bearings can be rolled in one at a time. A liner please puller is pretty essential. I use a 8000 lb auto crane for all my lifting. A chain hoist may be your only option

 

Not sure how big your cherry picker is, but your gonna need something pretty stout to reach in and pick that head off there.

Secondly, your gonna have to remove the engine to get the crank out because ALOT of things have to be removed. Front and rear structure most importantly.

Third, a BIG skidsteer will remove....but whoever is running it better be. D AMN good operator, otherwise i see something getting tore up. Thats my opinion.

 

Have never picke up a ISX head. 3406 head I have man handled on and off. Much easier with two men. Checking the crank , you can use plastigage .

 

Not sure why your thinking crank should come out. Did it spin a bearing??
If your truly set on taking crank out ,the engine must come out of the truck for that.
As far as the head goes you could just hire a local tow truck or crane truck to lift that off.

Engine mounts can be done with a simple bottle jack . Take bolts out , lift engine up enough to re@re mounts and drop back down. New bolts back in.

Have you looked into how the twin camshafts are timed in an isx??
There not your average engine , they use special wedges to set up the cams.

 

Before you start go to www. cummins.quickserve register yuor engine S/N and check all procedures have to be done to finish this project.
One small mistake could be a disaster later

 

you will need over 4k in special tools. have you done cam timing then there setting jake and valve and injector and liner height this is not anything near a gas engine. do you know how to take the pistons apart? can you pull liners? Can tell your in over head by wanting to remove the crank. This is not a back yard job. but good luck

 

Yup you need cam wedges timing pin, big torque wrench 3/4" impact with a lot of torque for the head bolts just to pull the head off. 7 mm feeler gauge thing for the jake rocker clearance.
inch/ pound beam style torque wrench to set the injectors a small slide hammer to pull the injectors and a liner puller for the liners. Then some stuff to measure liner protrusion before you pull them. The head is one heavy SOB, so is the engine, weighs quite bit more than a D60 Detroit

 

Like everyone else said, do your research before diving in to make sure you know all the specs and tools you need. There's no point in spending the time and money on an in frame if its not done right. That being said, your entire HVAC unit is held in by 4 bolt and 2 nuts so get that out of your way after you drain the coolant and recover your A/C refrigerant. I made a bracket with a mig welder and 1/4" plate to bolt to the top of the head once the cams, rockers etc. are out and just snatch it up with a forklift. Cherry picker might get it depending on weight rating, with the HVAC unit out of the way there is plenty of room on the 387's to get it out. The oil pan is going to be off so just jack up the back of the engine block (with a block of wood between jack and block) and swap those motor mounts out. One you can slide out when the bolts are out, the other you have to get out over the transmission.

And take a long hard look at your leaf spring hangers, they are SUCH a pain to swap on a 387 because the motor mounts cover the bolt heads. So if there was ever a time to make it easy......

 

Just did one using a two ton hoist. You really need three people. When you get the head that high in the air,it wants to tip. One person is just for anchor and working jack.
