PCU5000 and Van's VA-183 mounting bracket problems

[Pmerems]

Gents,

As I mentioned in my initial post that there is a problem with the latest bracket (VA-153PC) and the PCU5000.

I spent many hours trying to figure out a solution that was acceptable to me. I made a few similar brackets to the VA-153 that fit the PCU5000 properly but still had several issues with respect to installing the bolt and still have acceptable clearance during the arm rotation. I wasn't satisfied with the results.

I looked on the web for photos of the VA-183 to see how it was installed. I called Van's to see if they had any old stock of the VA-183 but they didn't. I was told the reason Van's stopped selling the VA-183 was because builders had issue with the bracket interfering with the oil hose coming off the rear of the accessory case. Several photos on the web show this interference and many builders cut away some of the bracket to reduce this. However cutting away the bracket also reduces the strength and rigidity.

So I decided to design my own bracket that captured the best of the VA-183 (mounted to the base of the governor and no control arm bolt installation issue ) and the VA-153 (alignment to the forward side of the control arm-allows a generous control cable radius from the firewall and keeps clear of the oil hose).

After several iterations I am proud to say I accomplished my goal, a bracket that works great with the PCU5000.

I can get more photos of it installed if there is interest. The bracket is made from 4130 steel with all cuts and bends were made with simple hand tools and a vise. I can have a engineering drawing available if requested.

Not sure about others, but I would sure appreciate a copy of a drawing if you can make one up.

I would also like to see a drawing

It would be great to see a picture of it installed too!
Thanks for your original post and great pictures that got all of us talking about this.........it really help everybody!

Sure, I'd like to see a drawing.

Gents,

Here are some photos of the bracket installed. I will work on the drawing over the next few weeks and post it on my website. Sorry the text is fuzzy.

I hope this helps.

Looking forward to your drawing. Nice Job.

This bracket looks like it may have some flexing issues under normal use.

Looking at the lower left picture, If a brace was to go from that screw just fwd of the
bracket, and the brace ran up to the cable case hole at the end of the bracket.
The brace would be in line with the control cable and stiffen the bracket.

I am getting ready to order a governor and I was sent a form for specifications and I don't know these answers. Specifically it ask for:

Drive Ratio
Rotation Facing Base
Control Lever Angle

I have a Lycoming O360A1A and a Hartzell prop.

thanks

With the fairly recent PCU-5000 group buy, what are folks currently doing to mount these?

Looks like the pictures from this thread are gone. Can someone repost them?

Thanks,
