Default Central GA Generator head replacement

My generator seem to run fine now, but thinking of trying to get ahead of any future issues. I'd like to rebuild the engine and possible put in a new power head. Central Generator gets some good reviews. I have seen a couple posts but nothing that goes in to to real detail with the change. Is there something I'm missing?
At this point I feel comfortable doing most of the labor. What should I look at while I'm in there? Any pit falls I should look out for? Is this a worthwhile change? Seems many buy a new complete unit. I'd like to have the better efficiency and some of the features, but the price difference between a rebuild w/ new head compared to a new unit look to be significant.



Thanks!

Shane Fedeli did one on a PT. I believe he posted lots of pics. I will see if I can locate the thread. Definitely a good idea. Those old Kohlers are hanging on for dear life, and not cheap to repair. I did my previous FC after over $2000 invested in Kohler in several short lived repairs.

I have a couple of use generators out of Birds.
One is the Onan diesel that came out of an SP,same unit as the 87-89 FCs.
1800 hours,good running and powering unit.
$3000



I also have a Powertech generator out of a M380,2004 model.
its in a quiet box,which may not fit into the space you have on the FC.
$5000

Here is Shane's experience. The Central Georgia Head is identical to the Stamford. When I did mine from CGG the doc still had Stamford on it. Shane tried to fix the Kohler first, lots of time and money spent before just replacing it.

There is also a Stamford brand available from

I have a PT35.



I "think" I can put a new gen head on and rebuild the Perkins for around $2,500 - $3,000.

The old perkins is a great engine,loud and drippy,but i'm not sure you can wear it out (the engine).
I would reseal it and run it.

I had a very leaky front crank seal so I decided to take mine all apart and reseal everything. I didn't use any of the junk cork gaskets that came in the kit for the front cover, valve cover, etc (everything else that leaked). I cleaned everything up and used Ultra Grey RTV (correctly) and it's worked perfectly. I also had the injectors rebuilt because it had a miss under load and that took care of that issue. The gen head is still untouched original, but the voltage regulator seems like it's iffy so I'll probably just replace it with a brushless 15k or similar. That engine will run forever, I wouldn't waste my time rebuilding it.

I have changed out the heads on both of the PTs I owned. I bought both new heads from Central Georgia Generator. Good folks, no problems. Change out is pretty straight forward, other than everything is very heavy. Once you slide the generator out of the bus, go ahead and renew the insulation. I was amazed at how much difference that made in the noise level.

I spoke to Central Ga. I used the info found in an old post. Without shipping the cost for a 13.5KW head is $1179.I have some stuff I'll want to address on the engine while its out.

We have a trip planned for end of July but nothing after that till WOG. Might be a good time to do this...

Tom down at CGG is just the most genuine guy you'll ever deal with. We've been buying his units for some time now.
