Engine swap project update

The engine swap is going well I'm glad to say. Since this is the donor truck, and cab will be removed, I decided to go ahead and remove the grill, and core support to make engine access much easier. All that's left to pull the engine is to pull the bellhousing bolts and engine mounting bolts.

Deflected deflector and reaming.

Last week I started a blog on an inline 10 cylinder injection pump, here is the continuation. 

Once I finished teardown, I found damage in the a pluger bore. One of the player assembly reflectors had moved and the higher pressure cut through the narrow part of the bore wall into the next bore. 

Here's the plunger assembly with the deflected deflector. It's the part with the small holes, it should be up against the body. 

Another project I had was to install and ream new bushings in an injection pump housing. I got a picture of the reamer during the process. Lots of tapping fluid and some patience yielded a good result.

Injection pump teardown

 After being sick for almost a whole week, a couple weeks ago I started doing some work for the fuel shop part of the business, a change in direction, and new learning experience, from vehicle and generator service.

Last week I started tearing down a unique 10 cylinder inline injection pump. The teardown is going well, it's slow, but I'm learning the steps involved.

Torch pictured was to hear up body to get a plug out.

Important to keep sections coming off pump during tearing together so they will go back together in same position, and not get mixed up.

Pulling freeze plugs was tedious, but gives access to next phase of teardown. My day ended after this step.

To be continued next week...

Engine swap

Engine swap project started. Started by pulling accessories off engine. 

 Continued

Inside top of DB2 injection pump. Pulled pump to check it out, showing evidence of presence of water.

Wear showing in advance bore.

                        

 Corresponding wear on advance plunger. Pump to be rebuilt, then installed on donor engine when ready.

VW Intake blockage

One of my projects last week. Owner of 03 VW TDI complained of  lack of performance, and check engine light on. The egr, and egr cooler had previously been cleaned, and the MAF sensor replaced. The customer mentioned the intake had also been cleaned out in attempt to fix the issue. The engine ran better with MAF sensor unplugged(it reverts to default setting in computer I believe), but wouldn't rev or get up to speed anywhere close to how it should've. We decided to check the intake runners, and intake ports in the head, to check for coking blockage.

Intake manifold behind the egr. It looks wet, but is dry.

Ready for intake removal

Soaked intake with solvent during lunch.

This coking was mostly in the elbow between the intake plenum and the runner the the egr bolts to. It was missed by whomever had cleaned the intake previously. There was almost 3/4 of a cup of material blocking air flow. 

After re-assembly the car was test driven, and performed as it should, no hesitation to reving, and drove well.

I learned to be thorough when cleaning parts, as the blockage in the elbow of the intake could easily be missed(as it was by previous technician who performed the procedure), and the problem would not be fixed.

  Week 7: 40hrs

Total: 280hrs

Gen Set Self Oiling

A look at one of the projects I worked on last week. I started removing the self oiling system from a gen set that no longer needs it. We're going to be installing the system on another gen set that is much harder to access frequently. 

Here is the float housing and sight glass for setting up the system. The oil level needs to be a pre determined level in the sight glass, which is the same level in the oil pan(or reservoir if not using the factory oil pan). When the level goes below the set low level, the switch(in next picture) opens a valve and more oil enters the pan. The oiling system also gradually changes oil over the recommended oil change interval.

The small light gray box in the lower left of picture with the hoses entering and exiting it is the switch for the oiling system.

The mounting bracket for the float housing.

The power for the switch is the orange lead coming from spot 7 on the green terminal block.

I learned how an oiling system works, at least how this one works, and how to disassemble it. I hope this will make installing the system on another gen set less confusing.

5th week total: 40hrs

total: 200 hrs

Making tracks.. continued..

Main project last week was focusing on getting tracks ready to put back on snow cat. I replaced the lacing that holds the track ends together when mounted on cat, and with help from my boss Stan, we were able to get the tracks mounted.

The old lacing was rusty and getting thin, with broken teeth on some.

Lining up new lacing

Special hardware for tracks installed, the excess length gets broken off

Heads held in place by tabs in lacing base

Tracks ready!

Tracks mounted, still needs some adjustment, but it's working again.

I didn't get pictures of mounting the tracks, it was an adventure, and required patience. We used a couple heavy ratchet straps on each track and slowly inched the ends together until we were able to gets pins(5/16th bolts) through the lacing.

I learned I need to know when to ask for help, and teamwork is important.

week 4: 40 hrs
