Easy find information for your PTS genset.

This page makes your parts search easy!

Thanks to Jimmy Spears @ PTS.

Here are some helpful tips when it comes to replacement parts on your CD7000 and CD8000 generators.


Radiators: Power Tech has two sizes when it comes to the CD radiators. From top to bottom, the measurement will be 13 inches (Click Here for this Radiator) or the measurement will be 16 1/2 inches (Click Here for this Radiator).
Radiator hoses: Power Tech has two configurations when it comes to the upper and lower radiator hoses. If the upper and lower hoses are on the same side of the engine, it will require two of the lower hoses. The top hose is cut to fit, but has the same bend as the lower hose. If the upper and lower hoses are on opposite sides from each other on the engine, it will require one lower hose and one upper hose.
There is also an upper bypass hose and a lower bypass hose on the CD models. Note that the lower bypass hose is part of the lower radiator hose system. You will have the lower radiator hose coming off of the radiator, then it is connected to a metal hose. From there, it goes to the lower bypass hose and back to the water pump.
Thermostats: Kubota has two different size thermostats on the 05 series Kubota engines. The best way to tell the difference between the two is to measure the thermostat housing mounting bolts center to center. The measurement on the thermostat housing bolts will measure 2" on center (Click Here for the thermostat) or it will be 2 3/8" on center (Click Here for the thermostat).
Generator Ends: The CD Models had both Exciter type and Brush type generator ends. The best way to tell what style generator end is on your unit is to look for a 3 inch panel above the end bearing on the generator end. If it has that panel, it has brushes. If it does not have that panel, it is an exciter (brushless) type generator end. If you are replacing your generator end, the only replacement is the exciter type generator end. If your generator is a brush type unit, it will be converted to an exciter type generator. Click Here to view this generator end.
Note: We do not have replacement stators or rotors for the brush type generators.
Regulators: With the information listed above about generator end types, picking the correct regulator should be easy. If your unit is a Brush type generator, you will need the VR 2.1 regulator. If your unit is an Exciter type generator, you will need the VR 2.4 regulator.
End Bearings: The same information for the generator ends are used for picking the correct end bearing. If your unit is a Brush type generator, you will need the 02BRG6304 bearing. If your unit is an Exciter type generator, you will need the 02BRG6206 bearing.
Brushes: If you have a brush type generator, there are three possibilities for the brush assembly. If the original brushes are on the unit. Look at the color of the brush housing. It should be brown, black, or white. If the brushes are brown or black, check the springs. The springs will be internal or external (looks like a coiled clock spring).
Brown or black with external springs: Click Here
Brown or black with internal springs: Click Here
White brushes: Click Here
Note: Please keep a record of the original brushes that were on the unit. That information will be helpful for future brush orders.
Senders and Switches: We only have one temperature switch for the CD model. Click here to view the temperature switch. The oil switch could be one of two switches. Check to see if you have a single post or a two post switch. Click Here to view the single post switch. Click Here to view the two post switch.
Solenoids: There are two possibilities for the fuel shut off solenoid. There's a two wire and a three wire solenoid. Click Here to view the two wire solenoid. Click Here to view the three wire solenoid.
Filters:
Click Here for the Oil filter
Click Here for the Fuel filter
There are three possibilities for the Air filter.
Click Here if your Air filter housing is metal
Click Here if your Air filter housing is plastic
Click Here if your Air filter is plastic and disposable. (Note: On this filter there is a Foam pre-filter Click Here)
Belts:
Click Here for the correct belt.
Fans:
Click Here for the correct blower fan.

Brushes

The CLIPPER PTS CD7000 GenSet has been acting up as the weather got cooler. Would not excite when temperatures dropped below 55*. But would work great later in the day when things warmed up?

Frustrating or what! Those early morning decisions to run the battery bank down to make coffee or resort to the LPG and brew it the old way?

So while attending the largest fair in the "Valley" (CARP FAIR), and relating my problems to an old friend while relaxing in his PREVOST enjoying a cool one, he pointed me too a qualified technician that he had reason to use a couple years earlier. When I contacted him on Monday, he spotted and solved the problem instantly.

Pulled the unit out and freed up the brushes. (These are accessible only after unit is removed as they are on the end of the end of power head.)
Some other minor maintenance done and the PTS unit is back doing what it is supposed to do again.

Anyone in the Ottawa Valley area needing help, try Richard Pratt Diesel in Carp. Well equipped small shop, and you get to talk to the guy who does the work.

The CLIPPER is once again comfortable as we are nearing the end of our boondocking extended stay in the Ottawa Valley on this 2016 tour.

Expect to be back at home base on the west coast sometime close to Halloween.

Dave

Brushes replacement (painful/humorous) and more

Great Post Masseyfarm. We've had our 1995 65th edition for about 1 year now and have put about 1500 to 2000 hours into remodeling and upgrading it. Your previous posts have been lifesavers. Everything you have posted, that I have read, indicates the equipment is identical in all respects. Ours is an early 1995 edition but at the beginning of the magic 25 built. We are located in Columbus Ohio but have vacationed in BC in the past.

I have a few minor issues and would love to have a private email discussion. It is just a few minor things that could be improved.

Now for the entertaining brushes story::::::

As for brushes, I am really impressed your technician/you were able to get the exhaust removed without breaking the exhaust manifold. Ours is a bit rusty and several techs (plus myself) felt it was way too risky as the cast iron pipes going into manifold look like they couldn't easily be removed without undo risk of breaking the exhaust manifold. So, with about 1000 hours on the genset, I still wanted to be sure the brushes were as good as possible. I resorted to more drastic measures like using a cutter/grinder to cut through a square of the support metal right where the generator brushes "door" is located. It took about 4 hours to carefully cut through with spark protection everywhere and to not heat up the hydraulic tank for the leveling jacks. You really can't line the hole up perfectly but can get close.

With a lot of effort, I was able to remove the door and with more effort at odd angles was able to remove the old brushes and find out they were the external spring version. I put the old ones back in and ordered the new ones. When they arrived, I thought I could get them installed in about 15 minutes as it was so easy for me to do now. Wrong.

I removed the old ones and then started to install the new ones. It was very tight and very hard to do as the new brushes were made different and you had to figure out precisely which wires to connect to the brushes so as to be exactly correct. I called PTS and they intricately described how to hold them and apply pressure so as to not break the carbon contacts. All was going well, until....... the dropped from my hands because it was so awkward and tight.

They fell under the armature and down to the bottom. I had to cut the square in the support metal lower and use screwdrivers to carefully walk the brushes back to the top. I thought I had completely bricked the thing and rendered it worthless. It took about 6 hours and 2 failed attempts before successfully "walking" and maneuvering the new brushes back up to the door hole so I could get them out.

Bottom line, make all tab bends (two are required) and connect the wires and maybe a big log chain (not really) to the new brushes before installing them. It will save a lot of sweat, worry, and pain and agony.

I then installed them exactly as described by PTS so as to not strain or pressure the carbon on the brushes and reassembled it. I then fired it up and it all worked perfectly. I've run it about 30 hours since with no issues.

As for the generator itself, when we first took over the RV unit, we did have one of the safety switches (a relay switch) that was bad. PTS claimed they never used that relay and that was a problem. It took about 25 hours of tech time and my help to diagnose and rerewire a different brand relay to make the unit work properly. At $139/hour that was a very expensive fix ($3500) by an authorized PTS dealer for which PTS wasn't very helpful - however, in general I've had subsequent experiences that were very good.

The genset has subsequently been very reliable and has run for 10 to 15 hours at a time when boondocking or when driving in 90+ degree weather and needing to run the rooftop ACs to have any chance of keeping the inside cool.

Great post Masseyfarm!!!!

I just want to correct post #4 in this thread.

The PowerTech CD7000 has the pre-heat option instructions on the external rocker switch in the generator bay. And this option does also works on the cockpit control.

I need to point out that this option also works from the rocker switch located in the cockpit. Just hold down the off side of the switch and the pre-heat will be activated. Hold for 5 second intervals, 3 or 4 times, for -5*Fahrenheit or longer if it is colder than that.

I found this out when I tried to open the genset compartment door today and it was frozen shut with the recent snow and sleet. I thought I would try the switch inside to see if it worked the same and (surprise) it did.

Another example of the quality that was built into Airstreams first big Class A Diesel Pusher motorhome.

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.
