Red face Spring isolators - stupid question

This is one of my old spring isolators mounted on a new spring.

Stupid question - should the spring be at that angle? I think this is the top isolator but I'm not 100% sure. Part number is RKB100970.








Below is the other isolator (the bottom one?) - part number RKB101290.

I don't remember what angle the springs were at an angle before I took them off but I suspect the answer to my own stupid question is probably yes.

TIA.

I think you will find that when in place and therefore under some compression, the angles will change anyway.

Make sure the bottom one leaves the drain holes clear on the arm.

I hope so - it looks pretty weird at that angle.

I will (unless I forget). I haven't cleaned the bottom one up yet - when I have I'll plonk it in the arm just to see what's what. I've actually changed the rear springs before but I can't remember what I did and I didn't take any pics either.

Kev - does this look right to you?

Here's the top of the upper arm with the isolator pushed into the locating socket and lined up with the drain holes.



Now, without changing anything, here's the arm turned over to show the bottom side.

The two locking lugs on the isolator are at 10 past 6 - is this fully locked into position, or should the lugs be at 6 o'clock to be fully locked? (the drain holes won't line up if it's at 6 o'clock ).

I have a feeling that if you revolve the spring 180 degrees it will sit differently.
I think the rubber is correctly positioned.

The spring isn't there though in these pics. Do you mean rotate the isolator 180 degrees so that the part number (RKB101290) is on the left instead of the right?

Hi Simon.
The ones I have in the shed also lean a little, if you press on them a pull to one side they straighten up.

I note you have the Indian arms was it not those that Brian mentioned that the drain holes were in the wrong place ?

yes, rotate the rubber and spring as the spring I think will only sit properly on the rubber in one location. See post 1, combine with my reply it will sit differently once on the upper arm and in place.

I only did this a couple of days ago and still I'm not 100% certain, that's not sarcasm, by the way

Thanks for the pics Steve.

Ok re the weird angle - I'll give that a try when I'm ready to put them on the car. At the moment I'm stuck on the fuel tank refit - post 13 here. I can't figure out what goes in those guides and clips, which I can't even see because the wood support blocks are slap bang in the way, plus it's raining .

I don't know about the Indian arm question - I never read the thread containing Brian's thoughts on it. The arms came from Mat in March 2017. I'll compare their drain positions with the old factory arms once I've sorted out the fuel tank problem (assuming I do that is).
