Hose Protection Sleeve (10 replies)

Looking for some advice on fitting the nylone sleeves to the rear subframe that protect the displacer hoses where they exit the frame. My old frame had these fitted but without the retainer plates. I bought new sleeves and retainer plates for the new frame. When I install the sleeves over the hose and through the hole in the frame and then fit the retainer over the end of the sleeve the retainer will not fit flush onto the frame to enable me to screw in the self tappers. There's about 1/8' clearance between the retainer and the frame all the way around. The retainer is wedge shaped to allow for the angle of the frame, turning it does not make any difference to the gap. Without the sleeves the retainers fit nicely over the hole. The end of the sleeve fits nicely into the retainer when not on the frame. So it seems that the sleeves are protruding too much from the frame. I shortened one of them as I thought it was bottoming out but it made no difference. Am I doing something wrong ?

Your'e not doing anything wrong but the repro hydro frame isn't up to scratch

It's a Heritage subframe not repro'. Might still be the issue though but hopefully not. More likely the repro sleeve/retainer I would think.

Indeed, may be the Heritage quality issues, however in this case I doubt it, the frame is identical to the old one with regards the exit holes for the hoses (ie. the holes are swaged out slightly) so it's more likely the sleeve/retainer. I'll just fettle these to make them fit properly.

Would this be the same original Heritage rear hydro subframe that doesn't have the grooved plates for locking the displacers into the frame?

I had a similar issue recently with Mk3 S and the Subframe was an original factory.
I believe the issue caused by the Repro Retainer plates.. the recess for the plastic sleeve rim not correct profile/depth. They're quite thin qauge tin as well so mine pulled up not to bad with some perceverance.
Unfortunately there is a lot of well documented poor fitting repro bits and bobs and possibly the factory items were never that great in the first place! (Door fitment and gaps springs to mind).

Very difficult for the perfectionist when the car was never built perfect in the first place.

I managed to get them to fit in the end. As you say the plates aren't guite correct. I flattened out the internal bevel to enable them to fit over the end of the sleeve a bit better then once the screws were tightened it pulled in the rest of the way to fit flush to the frame. Trying to avoid repro parts where possible (if new or NOS is available). Made the mistake of buying some repro knuckle joints, very poor quality and not worth the risk using them. Should have realised they wouldn't be quality items given the price, never again,

I've come across this thread eight years late! However, I've recently had the same problem. The reproduction hydrolastic sleeve retainer isn't anywhere deep enough for it to sit properly against the subframe surface.

I've attached a picture showing the reproduction version side by side with the original. The reproduction version needs to be about half again as deep as it is to be like the original and so fit flush onto the subframe surface when the plastic sleeve is under it. Note that when fitting an original retainer it will only fit one way round.
