My boss told me that we will be working on LCFs now. I got the " Tell me what we need to get to work on these things. " I went to school for this last April. Currently we work on vehicles up to f450, and maybe sometimes a f550. I know that we need WDS diag. support kit# 418-D553, and was wondering if Rotunda makes a kit to make IDS compatible. I was wondering what you guys would suggest as far as shop equipment. I'm sure we will need a bigger floor jack and some bigger jack stands. Any advice would be greatly appreciated

If you took the course, you should have all of the special tools needed to service the LCF. The tool kit supplements the 6.0L tools as many of them carry over to this engine. Included in that shipment of tools is an IC4 COM cable and interface module used to communicate with Navistar modules and WABCO braking systems on the 650-750 trucks. It is used with the MD Truck software bundle which currently only works on WDS. I understand the IDS version is coming shortly.

 

As for shop equipment goes, the LCF is similar to a F550 in size and weight so if you can handle them you should be okay.

Well you see, if I work on a f550, its usally one that we can lift. We do not have anything that can lift a LCF. We have a drive on rack that is good for 12,000lbs. but is in a spot where there is not enough room for a LCF with the cab in the forward position. I'm planning on using floor jacks and jack stands.

Is that how it is done or do most of you use lifts for these really big trucks?

The LCF isn't really that big it's comparable to a F-450-550

If you build some stepped type ramps (I used stacked up 2x12) to drive the front wheels up on 8-10" high gives you enough room to get under for service work.

it's faster and easier than lifting it for simple service work other than that most have been pretty trouble free.

That one of the pro's to working in an "older building" nobody will install that kind of lift anymore at least not way out on my side of the earth, something about hydraulic lines under ground and the DEC. I used to work at a shop that had a lift like that picked up any thing fire trucks, school buses,dump trucks etc.

There are also many above ground lifts that are quite suitable. There are drive-on lifts for trucks and conventional hoists that lift from the frame. My shop also has three Rotary 15,000 LB two post lifts that lift from the frame. They are perfectly suited to lift trucks all the way up to F550's and LCF's The only difficulty with those lifts is trucks that have large frame mounted tool boxes hanging below the body.

My "ex"lift is/was a 27,000 pound, four post Forward... one of two in the shop. Front jack beam was good for 8000 and the rear something like 12000.

 

We finally have some new crew members and I relinquished my hoist to a tech experienced in alignments since my other duties have left me with reduced billable hours.

 

One more similar is slated for the new bays...
