Generac

Servicing a residential back generator. Natural Gas fueled. So happy the front housing cover comes off, made the oil change much easier. Using a pump to such l out the oil certainly speeds things along as well.




Generac transfer switch doesn't have the control to set the exercise time, unlike some other transfer switches, but I was able to set it through the control panel on the generator itself .
                     

Many home generator units look alike, but have little differences in control panels, housings,  and transfer switches. My job entails learning the differences and how to service and test whichever ones I come across.

Engine swap update

Donor engine finally in destination engine bay, bolted down and connected to tranny. New parts: pilot bearing, throw out bearing, water pump,  several gaskets, rebuilt injection pump, a couple injectors, return line kit, and probably a few more to come. 


What a project, taking a long time mainly because I only get one day a week to work on it. Two engine pulls, and one installation in progress.

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.
