I’m removing the engine and transmission ( automatic) from my 62. Once it’s out I’d like to install it in a stand for working on it. This is my first Jaguar, I have no clue on how to mount it. I have a stand that has only held an Alfa 4 cylinder engine. What do I need for this engine?

 

you can use the same stand as for the Alfa. You need 4 bolts, two with nuts. The stand "arms" are movable so the top arms form a "Y" and the two bottom arms form an upside down Y.
The transmission must be removed from the engine. The arms bolt to the same holes as the transmission.
Note: there are two types of stands; One has short bottom legs and the other one has long bottom legs. If you are in the USA, try to use the one with the long legs. Harbor Freight stores have both types but you can check in Craigslist website where they are sold used for a lot less.

 

Some like to use an engine mounting bracket (DIY or bought from SNG Barratt) and attach the engine side on to the stand. It reduces the stress on the stand and allows access to the ends of the block.

 

Below are a couple of pictures of my engine 3.4 Auto going on to the engine stand. Once the engine was bolted on a could remove the engine crane but later I attached the engine crane to the head as this was really tight to get off. Normal problem of a bit of corrosion between the head studs and the head. The engine crane did the job of putting even pressure on the head and with the use of a large rubber persuader the head eventually eased off.

 

I did not trust my new Harbor Freight engine stand, despite having a more than adequate weight rating. It has a single bar at the bottom and the wheels come off of that on cross pieces. I cut a chunk of 2x4 and put it between the bar and the sump for a little extra assurance. Once the head and ancillary components were off and it was time to flip the engine over, it seemed light enough to trust the stand.

 

I don't trust those stands either, but amazingly, there are no reports of failure. 4 bolts holding the entire weight of any engine do not seem enough, so like you did, I added 2 x 4s to the front of the engine under the sump, attached to the stand legs with brackets.

No matter how you look at it, it is very scary to pull that engine out with transmision attached, and then to attach engine to a stand. I hired a mobile mechanic to do it and to him it was a "piece of cake".

 

It's a very heavy engine, and that stand doesn't look all that strong. When I rebuilt my XJ6 engine in 1993 I bought a heavy-duty stand. Even then, it was very difficult to turn the engine round on the pivot.

 

one solution is to keep the Hoist connected to engine for assurance of weight support, though that makes it impossible to turn the engine.

 

My stand is very robust and supported the engine comfortably. I mounted it using the engine crane and don't know how else you could do it as the engine is extremely heavy as you say even with all the fluids out and ancillaries removed. Once the head was off it was well balanced and easy to spin upside down to get to the sump. I even used the engine stand to reassemble the engine after the machining had been done rather than a bench as with the stand I could still rotate it to do the core plugs and put the head back on.

 

I too have a less than desirable Harbor Freight engine stand. This engine is freekin’ big, compared to an Alfa all aluminum four banger. I like the idea of beefing it up.
