What are these?

They are to prevent the awesome torque of the 1725 engine form tearing itself from the bell housing.

Oh, wait a second, my 1594 makes more HP and torque and I don't need them.

That's right they're for added weight over the front wheels.

Superfulous. ( I know it's spelled wrong but it's time for bed and I can't be bothered)

Did I tell you all I went for a spin today. It was spectacular. And my engine is still attached to my bell housing. Must be those grade "8" bolts and nuts.

these look like a slightly different version of the manifold braces that were used on the single DD carb rootes motors. These steady the manifold by attaching at the point furthest from the block to steady it and one would assume help stop the manifold from coming adrift from the head via its own weight.

If I remember correctly, the Series II's did have a version of these. It was a stamped metal pieces but didn't come as far forward as they attached to the oil pan. (perhaps the pieces I had on my Series II came from a different Rootes vehicle but there were braces.)

I am betting at some point, Rootes had a stress cracking issue either with the bellhousing or the block (around the starter attachment point).

I'm not even sure who put these on my car but somebody installed it at the Invasion. :)

I can't remember if I had them when my old 1492 engine was in place.

Quite sure i am missing these, anyone care to rate their importance? I guess th factory thought they were.. that should be enough.. though how many people are running replacement 1725's in their alpines without an oil cooler?

Hi guys,

If this was a stress related issue with the gearbox/motor, do the bellhousing differ much between the Alpine series or was it a mounting issue? I am guessing that there are not many Alpine with these installed, as I know mine does not (my motor is not the original though).

Regards, Robin.

My late (last 300) Series III has these. I left them off at one stage in the resto, and then when I found them went to a lot of trouble to paint them and put them back on.

And now Eric tells me I needn't have bothered Arrrgh!! But wait - Eric has a 1594 engine and sunnby has a 1492 ??? Am I in the correct forum.

Sorry to take the p*** guys

Cheers, Vic

All five of my Alpines have them. I am guessing if yours does not then someone did not put them back on when they had the engine out.

The S IV (with 1725 engine) has them; the S V had them in the boot with most of the engine.

Maybe that's why it blew up on me!

And Sunbby doesn't have the 1494 anymore! :D

hmm i have them

mine are more made from sheet steel from the looks of it.
welded together and mount closer in then the photo on hear.
i made the assumption they are for strengthening the transmission to the block i would assume to prevent the bell-housing from possibly cracking under stress. other wise if you think about it, it is like the transmission is only bolted up like a halve moon. from the output shaft of the engine down there is nothing to support the trany. and the two top bolts are on flanges of "aluminum". i may be wrong about this all but i am glad i have them on my series 2 and will reinstall them on the put together.

any ideas on better seals for slowing the oil leaks. im rebuilding the transmission and overdrive and want to stop throwing kitty litter all about the place.

cheers

Those braces will only fit the 1725 block. The bolt patterns are different from the 3-main bearing early engines. That's why the sheet metal are used on 1600s.

When I bought my SIV, it had a 1725 fitted. It had these braces, but additional holes had been drilled at the mounting to the sump to match the 1725 sump studs, and the bell housing end was packed with washers to get the correct alignment. I had a set off a Hillman Hunter and tried them for fit, but the bolt hole spacong for the bell housing was different. I ended up making up one set from the two.

Can't be sure if they are necessary, but I have a set that fits.

Rich, how did the holes in the alloy sump match the holes in the bell housing?
