AndrewMAshton Posted October 14, 2020 Report Share Posted October 14, 2020 Hello All, getting ready to lift the engine out and I wonder if anyone has a photo of the arrangement using the lifting eyes, I have worked out how the front one fits but the rear one looks a little odd, it is the correct one that was supplied but not fitted when I bought the car, cheers, Andrew Quote Link to post Share on other sites
Ian Vincent Posted October 15, 2020 Report Share Posted October 15, 2020 Hi Andrew, I didn’t have a factory supplied one when I took the engine out of my car recently but I made one. It’s a simple strap that bolts to the engine via the rearmost exhaust manifold stud hole and provides an easy attachment point for the hoist chain. That was all the factory one appeared to be from the drawings I saw. Rgds Ian Quote Link to post Share on other sites
iain Posted October 15, 2020 Report Share Posted October 15, 2020 I think the factory rear bracket for the TR4a as Ian says attached to the rear exhaust manifold stud and then also the rear most head stud on that side.

RogerH Posted October 15, 2020 Report Share Posted October 15, 2020 Hi Andrew, the hook shaped bracket attaches to the top rear exhaust manifold stud AND the rear offside Head stud. It is usually left insitu when the cra is driven.

Ian Vincent Posted October 15, 2020 Report Share Posted October 15, 2020 (edited) I worked on the principle that the Safe working shear strength of a 3/8" diameter mild steel stud would be approx .66t (using a safe working shear stress of 6t/sq.in) which is more than the weight of the gearbox and engine combined, so the extra fixing to the head stud is unecessary.

Ian Vincent Posted October 15, 2020 Report Share Posted October 15, 2020 Maybe you had the stud in bending as well? Rgds Ian Quote Link to post Share on other sites

silverfox4 Posted October 16, 2020 Report Share Posted October 16, 2020 I did not like the stock lifting attachment arrangement under the head nut and so reshaped it not to be under that rear head nut, but instead (for now) positioned it on top of the head nut and fastened with another half nut. From the witness marks on the lifting attachment I could visualize the nut losing it's 105 ft lb torque setting as the metal is too soft for the purpose.
