Scott's engine support hardware

[Bank of SHO]

Lowes and Home Depot do not have 9/16" eye bolts. They only go as large as 1/2". Is 1/2" strong enough?

Lowes had the clevices, bracket, and 5/16" chain.

The bracket bolt seems awfully small. Is 20mm as deep as you can go into the rear block hole? I'm not questioning Scott; I just want to be sure with an engine over me.

When I built an engine support I too thought that the rear bolt was rather short, but it will only go in so far. It worked like a champ, too! Had great success with the engine support over a long time. It is MUCH nicer than having to rent a lift, too!

Should ask this as well: Is the M10 bolt for my gen. 2 the same depth as the M8 bolt on the gen. 1's?

For your clutch work it would be wise to keep a jack under the oil pan with a block of wood in between, just in case. My engine support was not as good as Scott's so I didn't feel like risking it.

Keeping a jack with a block off wood under the oil pan under the car during the whole clutch job is not a good idea. It might be for saftey reasons, but it'll probably at least double the time to do the clutch job as you need to get in and out from under the car all the time and working around it will be very tough.

Two 1/2" eye bolts should provide sufficient safety margin as long as the load is aligned with the bolt shaft (hanging straight down). The 20mm of thread engagement on the rear bolt that is through the flat bar and into the head is in addition to the friction between the bar and the head and the angle that the bar is engaged to the head. I found no evidence of the bolt and bar being damaged by the load after several days of supporting the engine/transaxle.

The load on the bolt is tension along the axis and a perpendicular shearing force across the bolt head. No matter what, if you get the bolt tightened against the flat bar on the head, that should be much stronger than a longer bolt that is placed through a chain link.

That arrangement will very likely bend the longer bolt with the bending moment load applied farther from the head. When the bolt bends, it will weaken the bolt's grain structure increasing the likelihood of the bolt breaking. The bending bolt will also compromise the threads in the block.

Good Information. Thanks.
