Had to go with a 12 kW generator end back then... Quote Selected
Re: Generator refresh but with new style mounts Reply #26 – August 12, 2023, 10:17:58 am Its a very easy job once the thing is out. If you remove or relocate the metal tab on the bottom that does not allow it to come all the way out, and drill some more holes to move it further back, then you can let it come out further. Once out further could reach all that needs to be reached to do the job. I would definitely have a support under the front where its pulled out as that is a lot of weight teetering on the roller rack. BUT the entire left hand side which is a 2 piece bent panel, PLUS all the wiring going to the top section would also have to be undone. If you have to do all that might as well just take out. Seems I recall someone talking about it on another post, and I wish I had done it but did not. If that side panel had a hole with a secondary panel, it could be slid out for the most part, remove that sub-panel do the job. If I ever do mine again, and plan to at around 500 hours or 5-7 years to do so, then I will cut a large hole in that side, make a cover, and the next time much easier.Cutting that hole could easily be done with a grinder and thin cutoff wheel, but I would throw a towel or something over the gen in order to not have any grinder dust get into it.James Bock.....we spoke quite a while about this but I never mentioned this thought. I'd strongly consider adding that panel as part of your refresh and you'd be set for the next time. Quote Selected 3 Likes
Re: Generator refresh but with new style mounts Reply #27 – October 04, 2023, 04:19:42 pm Mike, You inspired me to do a refresh on my 93 U300 generator now that I have the time to do it since retiring. I have a 10K Powertech with a 4 cylinder Kubota V1305 in the side compartment and I was able to slide it out enough to remove the radiator and service it. I also removed fan shroud/doghouse in the other compartment to gain access from behind by crawling in there!Fortunately the slide out tray and the motor mounts were in good shape and all I had to do was tighten them up and do some painting. Upon inspection I found the back two mounts had worked loose and weren't bolted down. The ground strap was also unattached and could have lead to grounding problems.I removed all of the old insulation off the compartment walls, ceiling and the doghouse. I scraped off the old glue and replaced it with 1" self adhesive DynaCore DynaCore 1- inch – DynamatStoreI pulled the old cracked fuel lines and replaced them with new Gates 3/8" line from NAPA. I used the old brass fittings on the the tank and new ones for the fuel pump and return line connections. Got those from Home Depot. To make it easier, I removed the rubber grommet in the back wall where the lines pass through to the fuel tank and replaced it with a new one. Also while back there I was able inspect, paint the exhaust manifold elbow for rust and re-wrap the flexible pipe with exhaust wrap from O'reillys. It was very cramped in there but it can be done!The water pump was okay and I pulled the hoses off. All were good except the water pump return hose which I replaced with a new one. The metal water pump hose connector pipe was also good and just needed cleaning and painting. I bought a long radiator hose from O'reilly's with the right diameter and elbows to cut up for any of the other hoses if I need one.Replaced: Gates Truflex 1380 fan beltNapa Gold air filter 2276, Donaldson Filter Minder RBX 00-2252Napa fuel filter 3390Napa Gold oil filter 1344Prestone radiator flush50/50 mixture of Autozone Shop Pro conventional green coolant and distilled waterNapa 15w40 heavy duty diesel motor oilThe generator starts and runs much smoother now with less vibration. Seems to be much quieter and should generate less heat. I like the new insulation from Dynamat and time will tell if it was worth the cost. It wasn't easy to do and took me a couple of weeks but glad it's done in case we have a late hurricane this year.Jerry Quote Selected 9 Likes
Re: Generator refresh but with new style mounts Reply #28 – October 04, 2023, 07:17:32 pm Really nice project! Please advise when you know how the insulation worked. I am also looking to insulate the engine and gen, and, although I do not want to spend tons on insulation, want to use something that work...Peter Quote Selected 2 Likes
Re: Generator refresh but with new style mounts Reply #29 – October 05, 2023, 11:15:45 pm Thanks Peter,No complaints so far. I chose this product because it's new from Dynamat https://www.dynamat.com/wp-content/uploads/2023/06/DynaCore-Sell-Sheet.pdf and has both thermal insulation and sound dampening properties. It's 1 inch thick and has a strong adhesive backing. The sheets are light, very flexible and can be cut with a good pair of scissors. I bought 3 sheets of 32"x54" (36sq ft) to cover the compartment and radiator dog house.I used Hardie board in my refrigerator compartment like Pierce suggested and that worked very well and is extremely fire resistant, but with not removing the generator this was much easier to install. It's not cheap but I will use this for my engine compartment and report the results.Jerry Quote Selected 3 Likes
Re: Generator refresh but with new style mounts Reply #30 – October 07, 2023, 10:12:57 am Great to hear motivated a few.....can hardly go wrong with Hushmat, Dynamat or any of the similars. Just be sure you did use a roller to aid it in adhering. I have used similar for decades in auto restoration and have had a few times where it turned loose in spots before I learned about using a simple roller for install.....the same holds true for any of the foil HVAC type tapes, if you dont use a credit card or similar to flatten them with some force, they will eventually turn loose.As for insulation on mine, I used the foil/foam type that is commonly used around HVAC units that are in attics. Sound wise my setup seems about the same as it was before my work, which we were more than satisfied with. Quote Selected 2 Likes
Re: Generator refresh but with new style mounts Reply #31 – June 22, 2024, 11:59:06 pm Can anyone give me an approximate weight for a Powertech 12kw generator? I'm getting ready to remove mine and I'm not lucky enough to have a forklift. I would like to know how much weight I'll be dealing with. Quote Selected

Re: Generator refresh but with new style mounts Reply #33 – December 17, 2024, 01:11:20 pm Curious what your opinion is of the dynamat after it's been installed for a while? My generator housing is due for a revamp! Quote Selected

My generator housing is due for a revamp!It's held up very good so far and it has helped with vibration, noise and heat. It sticks to the walls and ceiling very well, but I made sure the surface areas were scraped good and clean first for the adhesive to adhere properly. I'm going to use it in my engine compartment and any other place that could use insulation like the firewall and the bay doors. This time I will go either the DynaCore or with the new the Dynamat ProX. Dynamat® ProX heavy 120mil butyl core & thick 5mil aluminum topJerry Quote Selected 2 Likes
