Prop governor bolts?

Davepar · #1 12-03-2005, 11:23 AM

The Van's instructions for installing the prop governor indicate the engine should have studs installed. My engine does not have studs pre-installed. I noticed on Walter's site that he used some SAE 5/16" x 1-1/4" grade 8 bolts.

Is that still the preferred route? And where should I get those bolts? I assume not from Lowes. Or where can I find the studs if that's the way to go?

Thanks,
Dave

I purchased my studs for my prop governor at NAPA.

Doh! I just looked in the goody bag that came with the engine and found 4 studs that look like they'll work.

Hello,

I found the studs in the bag as well. I assume the harder to turn thread goes into the governor adapter and the nuts will go on the easier to turn threads. Using the double nut method, is there a correct depth to turn these in to, or are there stops? Also, do you use #8 nuts and lock washers to hold the governor and bracket on?

TIA

Yes, those are the Studs! The reason we don't install them is they are installed to different heights for different governors. The end that the nuts don't go onto easily, is the end that goes into the engine. Double nutting is the way to install them. Install them to a height that will yield one thread exposed out of the mounting nut with the gov mounted on the drive pad. They are universal and will work with various installed depths with any of the currently supplied prop govs. The studs work better the bolts but you could use high quality bolts as well. Many governor mounting flanges will not allow the use of bolts so studs are the only way you can go with those style prop govs.
Good Luck,

I have one in to the correct depth, but the other three seem to have bottomed out. (the nuts will turn before the stud will) I stopped for fear of causing damage. Is this a case where I just need to apply a bit more torque? The studs have all thread showing past the governor, but there is far more than 1-2 threads showing. Is there a trick to getting the nuts to lock better?

Appreciate your help,

If you have adequate thread engagement from the stud to the drive adapter then you don?t need to screw it in any further. Remove the stud in question and examine the depth of the hole you are installing into. You will be able to see if you are bottoming by making a depth measurement with an unfolded paper clip and comparing it to the stud. If you are bottoming you have more then enough thread engagement. If you aren't and you want to install it deeper, really tighten the double nuts against each other and proceed. If that won't get it done, you may have to use a stud driver tool to take the place of the double nuts. If you have more then one thread exposed past the mounting nut with the stud properly engaged in the drive pad, that is OK.
Good Luck,
Mahlon

Mahlon, following up on mounting prop governors, 1) should the nuts be safetywired? I've never seen them done that way other than the pic in this thread. Also, 2) should gasket sealer be used or not? My Jihostroj governor is seeping preservative oil just sitting there in spite of tightening them as tight as I dare.

Thanks!

Star tooth or split lock?
