Where to Bolt Perkins 4-108 to Engine Stand

Looking for advice on my Perkins project. I bought an engine stand so I can work like a gentleman on my Perkins 4-108/Westerbeke 40. I need to bolt the block to the stand using F8 bolts-question is where on the block can I find suitable bolt holes that will support the engine while hanging from the stand? Engine weight 450 pounds and would not want to damage the block. I assume I need to remove the bell housing and flywheel...
All advice appreciated.
Jim

You can bolt to where the bell housing or motor mounts attach. On some engines I bolt to the crank, with the crank vertical.
Some attachment arms may need to be built.

Thanks for the feedback. I kind of assumed as much, but the idea of hanging 450 pounds off of four bolts makes me nervous. Guess I will just choose the mounting points with the least amount of cast passages around them

ID:	206430I place Perkins 4.108's on four wheel heavy duty trolleys that have 4 X 4 stringers for the engine mounts. Then I take the upper parts offf, including the head. I built a heavy duty table with rollers on the corners, stainless steel top, 24" off the floor. I use my engine hoist to lift the block. Then I can remove all parts, except the cylinder liners which I have the machine shop replace after they have slowly heated the block to 500 deg. F over 24 hours. That way any cracks can be detected and as it cools the old cylinders are pulled and the new ones pressed in.


BTW, the engine pictured has been rebuilt, tested and ready to ship.


How do you roll the pictures?

Tom,
Thanks for the tips. I spoke with another user who has successfully used the same stand I bought ($60 Harbor Frieght) and he had good results. Looks like there is plenty of meat behind the bell housing to accept grade 5 bolts. The thought of cracking the block or breaking my toes has been keeping me awake at night...not to mention I'm on the second floor of a shaky barn....in my nightmares it shears off the stand and drops through to the first floor...
should be a fun winter project.

I had a 2 story barn, built on a hill side so you could drive into the top floor. A gate got left open and my bull walked into the top floor and was feeding on alfalfa & fell down a hay feeding hole. Sure surprised the cows.

Ha! My barn was built circa 1860 or so. It has two of those trap doors for dropping hay, but I don't have any cows. It would just be me falling through the hay door.
