Title: mr-1 steering actuator testing
Post by: 75starflight on April 30, 2019, 01:55:27 PM
Does anyone have the procedure for testing the proper operation of the power steering actuator for the mr-1 drives?  I am looking at pulling Phoenix out of her 2 year slumber in the next couple of weeks and want to do a good check over to make sure my steering cable is free and my steering actuator is working properly.

I don't know of a technical procedure, possibly one of the Mercruiser manuals list something.  I'll take a look tonight.   To simplify, the actuator has essentially a valve that opens as the steering cable moves against the out drive arm.  The more flex, the more pressure applied to the slave cylinder.  Without the engine running, turn the wheel lock to lock.  It should move smoothly with not much effort.  When running you should be able to notice a difference.   Honestly not certain how much effort the power steering applies.  I have noticed on my CVZ, that once I got the prop and trim tab in harmony, you can drive with one finger.  I assume PS makes up for when I'm not at the sweet spot?  Other than that I'd maybe check pressures?  Saginaw pumps are fairly bulletproof.   On a side note, good to hear Phoenix is making a return.  Any CVZ progress, little hands are great for sanding tight areas of boat hulls.

Thanks for the input Mike. 

I am hoping Phoenix will not be a problem child once I get her running again.

The CVZ is sitting idle waiting for attention. We are hoping to purchase a different house over the summer. If we find one with a garage, I will get to work on it this winter after I do some work to Phoenix.
