     I have an RV-6 without a vacuum system but a friend that rents hanger space from me is installing a new 0-360 in his RV6A and the fitting for the inlet side (suction) of the vacuum pump appears that it is going to be very close to the motor mount. Question is this normal or is there a different fitting people that have vacuum system and 0-360 in RV6s use?  

   

            You can answer direct to my email.  

            Thanks,

Dick:



You have to be a bit more specific.  Can you answer the following questions:

1 - Which engine mount are you referring to?

2 - Which fittings are you referring to?  Check out ACS Catalog, and give me 

a part number.  They are interchangeable and different fittings are available. 

 



My general response is:

As long as you are using a standard store bought engine mount (dynalfocal) 

the vacuum Pump will fit.

You are talking about a DRY Vacuum Pump?

The intake and exhaust fittings can be varied in shape and location to have 

things fit.  DO NOT OVER TIGHTEN!

The ONLY problem I can foresee is the left lower NUT!  You must have the 

special wrench to tighten that one.



The RV-6A and RV-6 I fly both have dry vacuum pumps and fit is NOT a problem. 

 Both have 360's an O-360 and an IO-360 respectively.

Super Cautionary Note: I know the installation instructions say do not use 

Teflon Tape.  I am a bit scared to recommend it, because, quite honestly most 

people do not know how to use it properly.  There is a trick in its safe use.  

But Teflon tape may be required if when alignment is accomplished the fitting 

is still loose.

The vacuum pump is on the engine but will have to be removed to

install the inlet fitting which is no problem but it sure looks like the

90 degree inlet fitting is going to hit the dynafocal mount.

Dick:



would recommend that you:

1 - Remove the pump from the engine.

2 -Set up the input fitting in a direction that will not hit the dynafocal 

mount.

3 - Reinstall the pump to the engine.



As mentioned before the only difficult part is that you will need the special 

vacuum pump wrench.
