Old ST sumsp guard mounting

Post by AndyPen »

Just lining up my old sump guard so that if I wish I can bolt it back on one day.

The mani three front bolts are mounted on a plate that drops through, but anyone know if the same applies to the side mountings? As I recall we just welded some captive nuts into the subframe, and the part book pic suggests that as no nuts are visible?

So before I do it, any thoughts welcome?

I always weld on the captive nuts to the subframe has to be the easy way to fit any type of heavy sump-guard .. However i do not have the ST type sump-guard so i would use your own best advice.

The bolts supplied in the ST kit were big hex headed self tappers, as above if regulations permit just drill & weld on nuts.

Now you say, that makes sense and in terms of the parts book pointy bolts pic ;-) I am sure we welded - nuts in as they'd be a paint to reach in and hook up... and self tappers whilst available, don't quite do it for me. ;-)

The rear mounts have not been available for many years, unless someone happens to have some out there??

I finally remembered that we used Triumph Herald engine mounts as a close alternative, the holes need slight enlargement but that's all. So if anyone else is ever doing this job, Rimmer Bros still sell them ;-)

I thought the rear mounts were Austin 1800 gearbox mounts ?

That's interesting to know. I wonder if you can still get them if that's the case?

I think polar's idea is worth exploring for another time too. Back in the day I used to race a Dolomite Sprint, so that is where I probably picked up on the closely matching triumph mounts shown in my pic.

The dural guards we subsequently used were quite different, but I think these early ST ones look the part ;-)
