6.4 cab on fuel injection pump replacement

Robertg1970 · August 29, 2012

Hello to all.Im knew to this site

I have an ambulance that can not be de cabbed due to hard wiring,

Iv have to replace the Fuel Injection pump.would the quickest way be to remove the trans pipes then turbos? Ive heard some removing the turbos only?Ive got the trans off.Just wondering .we dont see many ambulances,Ive maybe Ive been lucky and have been able to de cab all the 6.4 I have worked on

Thank you.

If you already have the transmission removed, the turbo inlet pipes and outlet are a breeze to remove. Remove the pipes, leave the EDOC in place, then you've got enought room to remove the pump from the vehicle with the turbo in place. I just lower the vehicle enough so that I can stand up in the transmssion hump and work from there. You just have to torque the fuel pump gear on a bench, as there is not enough room to get a torque wrench in there with the cab in place. That's the way I do Detroit Custom Chassis HPFPs.

partial cab lift? I did the last pump that way (without removing the turbos either), it was hell on my back but it got done

sorry I missed that you have the trans out. we can't lift heavier trucks so trans removal is out of the question

I do a partial cab lift to do a HPP no matter if I can lift the cab or not(except on the 2 limos I've done where there was no moving the cab with the fiberglass limo body over the top of it), pull the turbos, and I can have the pump out in about 2 1/2 hours that way, ALWAYS torque the gear on the bench, saves the trouble of doing it in the cab Posted Image

What about a partial cab lift and leaving the turbo's in place?

I've got one to do this week.

Well I started one today like this just to try it. Cab on, no partial lift, turbo still in and the transmission out. I was going after the minimalist approach. I had to figure out what bolts to access from the top and what bolts to access from the bottom. It is doable however if I had any bolt or nut round off or strip this method will be a problem. I purposely refrained from using a torch on the exhaust pipe fasteners and I feel lucky... maybe because it is my birthday and the diesel gods gave me a gift but I often have SOMETHING strip om me.

Sucks. I hate doing this as opposed to cab off and as of yet haven't seen much time saving. Perhaps a second one will go faster. Having the cab off makes everything much easier to get to. I am on the fence on this one fellas.

Happy Birthday anyway!

It's good to know how to get in there though, in case the cab can't come off. Posted Image

I said the same thing and nothing ventured nothing learned... or gained for that matter. I just keep thinking about the something going wrong scenario.

Matt Saunoras · December 16, 2012

On the one I did I had to pull the pump cover back off because it didn't feel right when I was tightening it down(turbos are very much in the way of seeing what you're doing). it turns out one of the wiring harnesses under the cover was getting pinched in the process. I did get it seated fine but the whole time I had an uneasy feeling.

Cab on(partial lift) pump I might try again, but the turbos are getting yanked

joshbuys · December 18, 2012

I yank the turbos now, I did one with the trans out, that sucked!! I can have the turbos out in around 1 1/2 hours, it's easiest if you do a partial cab lift, but sometimes that's not feasible. Like on the Limo bus I did, but with the right tools I rarely round a bolt (knock on wood) Posted Image

Have you guys seen the socket made by snappy for the exhaust on the back of the turbochargers?

p/n S6210

Anyone have it, does it work?

Jeff Clyde · December 20, 2012

I have 2. One is mine, the other belongs to the snap on dealer. They work good, but are prone to cracking. Dealer gave me one from his stock to rotate with mine when its broken, so I am never without one. Some like the socket, some don't.

We discussed it HERE when it first came out. I am on my third replacement... which has lasted a while now. Thinking that Snap-on improved it.

Alex Bruene · December 20, 2012

It sure is a fancy looking thing. I just keep a few new 10mm sockets on hand, that I use for nothing other than 6.4 turbo bolts (until they get a bit worn, then they go in the normal rotation)... Along with a 3" wobble extension. The bolts will come out, or break, but they never strip.

Aaron · December 22, 2012

I have a special "10mm drawer" with new six point wrenches and sockets for special jobs.

I only ask on that socket because I won't be able to take the cab off my truck easily where I work if it needs any repairs.

With the ching you make, you can just pay somebody to fix your shit! Posted Image

I'm back to wrenching, but on garbage trucks.

City garage more or less.

LOL

We usually only see them with recycling in them, as the recycling is dumped on site at our facility where it's sorted and packaged for commodity sale.
