What is the max size bolt for the predrilled hole in the mounting bracket ?

The manual says to use a 3/8" bolt. Not sure if a larger bolt will also work.

I used a 3/8 lag bolt into a wood header. I also put on some rubber washers. I just used 1 bolt so it swivels but is very secure. Worked well for my application. Good fan.

For precise specs on the bracket try going directly to DT web site. http://www.definitivetech.com/

The hole are 6" apart both vertically and horizontally. I mounted my bracket to a 10" piece of 2x8 that is on a post ( landscape timber ) .

I purchased longer ones that were made for heavy duty leaf springs. I think there about 1/4 or 1/2 inch longer which will make it easier to re-mount the u-bolt.

Did you look on the underside for brand information? That's where I found it for mine.The bolt holes on this one are 12" on center.

This units have a standard hole of 14" x 14" We use a 1.5" lip for bolting purposes. Hope this helps

It has 6 screw holes and fit the original mount location perfectly. I can measure the hole diameter tonight if you need it.

It has three predrilled holes for mounting but I see no problem with drilling more for a custom fit.

Mine is already mounted so its tough to measure, but it looks like the holes are 7/32".

Unfortunately, there is no way to determine what type of hardware needs to be used without seeing where it will be installed; the best person to determine this would be the professional who installs it. The holes are approximately 7/16". Please let us know if we can be of further assistance!

I am using my engine for a custom built hydraulic log splitter. There are two bolt mounting patterns. One recessed around an inset circle and fits standard hydraulic pump brackets perfectly. The other is a square bolt pattern 'on top' of the circle. Those are I believe 5.25" on center, but I can't measure at this point because the pump bracket is mounted. I believe the documentation noted their size. Based on the bracket I am using, I would guess they are a very standard size because mine worked flawlessly...

There is a threaded hole. I use a Skil buffer so not sure of the size match up
