Frequently Asked Questions

We would like to announce the addition of a phone line specifically for technical calls. The new telephone number is (785) 891-3557.
If you are a mechanic, this page is geared especially for you.  Here you will find items such as all the component parts to rebuild the generator adaptor drive and component parts for a standard Vickers power steering pump, just to name a few.  Like all of our other pages, this page will get updated regularly so be sure to bookmark it for your future reference.  In addition, if you are looking for an item that you do not see listed, please do not assume we don't have it.  We have so, so many parts that it would be impossible to list them in the space provided.  Take a moment and look at the rest of our site.  We hope the information that we have provided will be helpful to you.  Feel free to contact us with your comments and/or questions.  

If you have a Webasto or Aqua Hot heating product and  are interested in learning more about them or have a nagging problem that no one seems to have an answer for, you have found the right placed to go to.
We are one of the oldest Webasto stocking distributors and premier warranty and repair facilities in the USA. We are knowledgeable with the entire Webasto product line and offer free technical support world-wide.

With the rising cost of replacement parts, it has become prudent, as it used to be, to rebuild components whenever possible in lieu of just replacing them. Below you will find breakdown of the Carrier 05G compressor. We have all parts in stock and ready for shipment. When placing an order, be sure to indicate if you are rebuilding a 37 or 41 CFM compressor.


Each of the items for this compressor are available for purchase. We will be adding the part numbers for specific item numbers in the coming days.  If you need any of these items, give us a call and we will assist you in every way possible.

Continuing on the line of increased cost but also saving money, we are offering rebuild or maintenance kits for many Bendix valves. Below is a partial sampling of the kits in stock. If what you need is not listed, please call us at 888-287-3499 for availability.
