Clockspring Install


Recommended Posts

:P

 

I'll bite, what does a "clockspring" do on an O3 Silverado??

 

In my line of work, a "clockspring" is used as a permanent repair on a gas pipeline. Different sizes available for different diameters of pipe in use. :nono:

The clockspring is in the steering column, behind the steering wheel. It has to do with the air bag system.

 

I do know that the Haynes manuals describe how do do it.

Ok, first and foremost - everything I'm writing here comes from GM's Service Manual for the 2003 Silverado/Sierra. I'm just the messenger relaying the info so I'm not responsible for anything that goes wrong. All procedures you attempt are at your own risk.

 

Removal Procedure:

** Steps 1 - 5: Refer to file Removal_Steps1-5.jpg

** Steps 6 - 8: Refer to Removal_Step6.jpg

 

1. Disable the SIR System.

 

2. Remove the steering column trim covers.

 

3. Remove the wire harness assembly (4) from the wire harness strap (5).

 

4. Remove the 2 wire harness straps (3) from the wire harness assembly.

 

5. Remove the wrie harness strap (2) from the upper tilt head assembly (1).

 

6. Remove the retaining ring (1).

 

7. Remove the SIR coil (2).

 

8. Remove the wave washer (3) from the steering column upper shaft.

 

Installation Procedure:

 

** Step 1: Refer to Installation_Step1.jpg

** Step 2: Refer to Installation_Step2.jpg

** Step 4: Refer to Installation_Step4.jpg

** Step 6: Refer to Installation_Step6.jpg

** Step 7: Refer to Installation_Step7.jpg

** Steps 8-10: Refer to Installation_Step8-10.jpg

 

 

1. Align the block tooth on the upper shaft to the 12 o'clock position (1).

 

NOTICE: Ensure all fasteners are securely seated before applying needed torque. Failure to do so may result in component damage or malfunctioning of steering column.

 

2. Install the wave washer (1) to the steering column upper shaft.

 

3. A new SIR coil assembly will come pre-centered. However, if centering is required, follow the instruction on the notice of the coil assembly.

 

4. Align the SIR coil (2) with the horn tower on the turn signal cancel cam (1)

 

IMPORTANT: DO NOT REMOVE THE TAB ON THE SIR COIL UNTIL INSTALLATION IS COMPLETE

 

5. Install the pre-centered SIR Coil (2) to the steering column upper shaft.

 

6. Remove and discard the centering tab (1).

 

NOTICE: Gently pull on the lower coil assembly wire in order to remove any wire kinks inside of the column assembly. Verify that there are NO kinks or bends in the SIR coil assembly wire. If a kink or bend is present, interference may occur with the shaft lock mechanism. Turning the steering wheel may cut or damage the wire.

 

7. Install the retaining ring (1). Verify that the ring (1) is firmly seated in the groove on the upper shaft (2).

 

8. Install the wire harness assembly (4) into the wire strap (5).

 

9. Install the wire harness strap (2) into the upper tilt head assembly (1).

 

10. Install wire harness straps (3) to the wire harness assembly.

 

11. Install the steering column trim covers.

 

12. Enable the SIR system.

    • This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.  
    • 2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.  
    • Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
    • Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
