The Clipper was equipped with a PTS CD7000 diesel generator. This is a Kuboto 3 CYL diesel engine of the "05" family.


This generator is not specifically listed on the Power Techs site today, but parts for it are listed if you search for CD7000 parts.
PowerTech Generators

There is some question about which model engine may be installed in the Clippers, as the 905 is generally found on the 6 or 6.5 KW models

I have not been close enough to mine to determine for a fact it is a 1105 model, but the Clipper Generator are rated at 7000KW and may well be the larger model. (I will update this when I can confirm but today I just want to detail some information for those with this unit.)

On the Clipper, these generators were OEM installed with no guages, but had fail-safe sensors to shut the engine down for overheating or low oil pressure.

The generator is rated at 7KW, 120V/58A and 240V 29A, and also produces 6A of 12V for battery charging. This is not a lot of 12V charging power, so if you are in need of battery charge, try to combine it with other use (microwave/air conditioning) for efficiency.

For some technical information on the Kuboto you can go to this site.
http://kubota.com.au/products/detail.asp?ca_id=8&pd_id=10&mo_id=D905

On my Clipper, I have installed a good supply of solar power generation, and as long as the sun shines, very little diesel generation is necessary.

I also carry, and use when the sun doesn't shine, an exhaust extension to lift the exhaust gas and sound above the sitting area outdoors.

This system has worked flawlessly for me so far, and with proper maintenance should last for many more years.

One of the problems with this site, is you can not edit your posts after a very short time.

After a good nights sleep, I see I have misspelled the engine brand name KUBOTA .

Here is also a good resource for general electrical information. Page 167 and 168 deal with various generators including the PTS CD7000.

Rv Electrical Systems: A Basic Guide to Troubleshooting, Repair, and Improvement - Bill Moeller, Jan Moeller - Google Books

One of the things that everyone will tell you is to actually use your generator on a regular basis. I use mine in combination with the two Penquin Air Conditioners to give the genset a good workout and to keep the AC and the ac system in good working order. A 4-5 minute workout will be sufficient. (your body requires a bit longer )

Some sample pictures of the PTS CD7000 below.




The new ones are like this.

The operators manual is available on the Power Tech site under the CD 7-8 column. It contains all the trouble shooting information you might need.
I have now printed that document for my records as it was not included with my original documentation with the Clipper.

The PowerTech CD7000 unit on the Clipper is pre electronic and should give many years of dependable service.

One drawback is,-- if you are trying to start the unit on a below freezing cold morning, the fuel prime and preheat is only available from the main control located in the generator bay. Hold the rocker switch for about 5 sec., release, and hold again for 5 seconds before trying to start the unit. If the Kubota does not start right away, repeat the above.

The OEM Clipper is set up to draw from the chassis batteries for starting power and the genset recharges the chassis batteries with 6 AMP output right from the genset while the house batteries are charged from the HEART inverter/charger.

Don't forget to exercise you genset at least every couple months. I did mine today.

Previously posted, I ran the PTS CD7000 for the most part of an hour to clear out the cobwebs.

Once the unit was warmed up I noticed a rattle in the forward area that seemed to get worse the longer it ran.(this would probably not be noticed with the bay door closed)

I spent some time determining that it was from the fan area rather than the water pump that I first suspected.

Weather was good today, so I got my tools out and started taking things apart.

The fan on these units are a cage style and rather difficult to access.

By loosening the rad from the fan cage, I was not really able to see any problem.

I fired the genset and when I pulled the rad back into position the fan contacted the metal shroud.

On re-assembly I found the simple solution was to tighten the rad/fan cage housing while holding the rad as far forward as the adjustment would allow.

This small adjustment is located on the top of the side mounted brace.

You can see the old paint mark on that bolt mount in the picture.

The other pictures show some of the additional storage within that bay.

Airstream used the same diesel generator (as an option) on my 1996 Cutter Pusher. It only had 170 hours on it when I bought the Cutter almost 2 years ago. This means that the previous owner only used it for an average of 10 minutes per month! There was a lot of crud in the fuel lines and I went through 3 fuel filters before it would stay on without stalling. I also changed the air filter, oil filter and the oil and I carry a spare fan belt and a few extra fuel filters. Now it starts right up, runs smoothly and has really saved us by providing lots of A/C as we travel extensively on I-5 throughout California in the hot summers. I've put over sixty hours on it since I've owned it. Be sure to keep more than 1/4 tank of diesel as the generator will not run. On the '32 Cutter pusher, the generator is located street-side, right behind the front wheel. In the picture here, you can see how the diesel generator motor cover rubs against the compartment door. I took this picture at my local radiator shop last summer. Apparently, the overflow hose fitting on the filler neck was also rubbing against this door and it fell off. The radiator repair man put on a new filler neck and relocated the overflow hose fitting so it no longer rubs.

Here's a newbie observation/question: it sounds like the coach a/c units will not run if the gen is off - is that right?

That is correct. You have dash air that is chassis powered and should work good on the highway.

The configuration, gen set, etc, is different after the 1996 models.

I finally have found it necessary to dig deeper into my genset compartment and I can confirm that the Kubota engine on the PTS CD7000 unit supplied for the CLIPPER is a 905-E series.

The later/current CD8000 series uses the 1105 Kubota and the larger rad.

We are pushing the limits of the boondocking lifestyle at the moment as we are on the road and have had to pull the CD7000 out for repairs. (details to follow on a successful reinstall)

The CD7000 weighs over 400# so removal is not a one man operation but with help can be removed to gain access for parts repair.

For future reference I will link this page as it contains some useful information you need to troubleshoot your problems.

Negative to Positive

If we try hard enough it is sometimes possible to turn a negative experience into a more positive feeling.

Removal of the PTS CD7000 has given me the opportunuty to powerclean and refresh the generator bay on the CLIPPER.

I hope to have everything back to operating status by Thursday evening and I will post a summary of events after we are up and running.

The sun is co-operating and we have full solar production again today so we are only having to drink instant coffee early in the morning.

Had everything back together and running by coffee time this AM.

The closest source of parts and support was thru a local Kubota dealer here in the Ottawa Valley. (Hartington Equipment) Mark and his crew offer, what we call, real SERVICE.

The 905-E now has a new water pump and coolant, hoses and belt, fuel filter and fresh oil and filter and new exhaust outlet.

For those who may have similar problems, this PTS genset on the CLIPPER needs to be removed to do the water pump, or other backside repairs. The Airstream box is not deep enough (PowerGear Jack is between it and frame) to gain access to the rear side of the unit.

The PTS just needs to be unbolted on the 4 corners and the wire and fuel lines removed, and the exhaust removed, for the unit to slide out onto a jack and lowered to the shop floor.

Airstream could have made this a bit easier by constructing the compartment base to allow the unit to be pulled with the exhaust pipe in place. The framing looks like they had that in mind but they put the slot in the front of the frame instead of the center area where the exhaust pipe is located.


We are happy to again have the backup power system in service as the days are getting shorter and we expect some cool fall weather before we make it back to home base in November.

We are so happy to have the PTS genset back on line. Yesterday we did not see anything but rain (at times heavy) and this morning here in the Ottawa Valley we have a chilly NW wind with heavy low cloud. We had our first frost on the 17th and the beautiful fall colours are on their way.

We are now 38 nights on the road, and having boondocked 37 of those, we are dependent on all systems working to make our CLIPPER as comfortable as home.

As we get later into the travel season, we will begin to see more of the RV services available to us closed, so being independent is always a priority.

A couple of ARC shots of this area.

Awesome job on documenting this repair Dave! I can see myself doing this repair sooner or later so it's nice to see that it can be pulled off all by myself. We continue to be finding ourselves staying in places with no hookups and relying more & more on our generator. We've now put more hours on ours in 2 years that the original owner did in 15 years. How many hours do you have on your genset?

Air Filter

Just a note on the air filter on this PTS CD7000 genset. This unit does not use a standard Kubota 905-E engine series air filter because of the condensed packaging of the genset.

The filter can be sourced direct from PTS in Florida, and is on their website. (PT# 04FA45001) They also stock the foam prefilter available from PTS. (PT# 04FAFM)

http://powertech.myshopify.com/blogs...odel-generator


The OEM air filter is a Duralite 546332 that crosses to a WIX 46332, or a NAPA 6332. This is not a common stock item at NAPA stores but, is warehoused and, can usually be shipped for next day delivery.

What you get from NAPA does not include the foam prefilter and I have not found another source for that other than PTS.
