I received some parts with my Tricarb. I have identified most of them, but not those on the attached pictures. If ayone knows what they are I would be greatful to be enlightened.

I don't think either of those--esp. the eye bolts--go on a Healey (at least, there aren't any of these on my BN2 and BJ8). The second one could be a brake cylinder piston, but not for a Healey.

Don't remember seeing either of those on my Tri-carb. but there were some things like the gearbox that had already been rebuilt so i did not go in to them.

The second picture looks like an overdrive accumulator piston with an 'O' ring conversion - AH Spares part OVD202A

The eye bolts in the first pic, I think are part of the seat belt anchorage ( I have them in a box of bits from my tricarb, yet to be fitted, but can't see them in the parts list so far!!!)

Thanks! That can well be correct, the OD was rebuilt about a year before I purchased the car so the piston may have been replaced.

I think we have a winner, though it's curious that it wasn't installed since the O-ring is supposed to be superior to the metal-ringed type (at least according to AHS). The DWR uprated accumulator still uses the steel rings. The activating pistons went from steel rings to O-rings in later cars.

Yes its an upgraded OD piston .

I believe that it was replaced for some reason (hopefully with another upgraded piston) when the OD was rebuilt. The one I received has been in a car, it can be seen on the top of the piston (not visible in pic though).

Any ideas on the bracket in the same picture as the eye bolts?
