The V8 Owners Forum -

another Q before i start with putting the rv8 in my sierra i just want to get everything done so i can crack on with it is there any easy way of bolting up my prop to a lt77 or will i have to get one custom made the car is a 2.0 dohc saphire
thanks

I think you will end up with having to get one made, as the LT77 has a flange on the back of the box, and as you are aware the diff also has a flange, so the prop you need HAS to have a built in slider joint, I have never had much success with the SDI CV prop, Most places that make props have the sliders in stock so it should not be a problem

thanks pal as i thought never mind will have to spend some hard earned

I've had a few props done over the years, at Recoprop and Bailey Morris. Both places have charged me about £100 for a shortened / balanced prop when I've supplied all the bits.

where are they based chris?

Recoprop is in Luton, just had 2 props made by them

http://www.reco-prop.com/

thanks will give them a ring

Last and only prop I have had done at Reco Prop cost me £475, needless to say I was not impressed, there are lots of companies dotted around the country who will make props for you and i am certain there will be one nearer than RecoProp.

I just had 2 made by them one with a slipper, cost 413 including postage.

These were outright articles and not modifications

Very impressed

Bailey Morris are in St. Neots.

I've had good service from both Bailey Morris and Reco.

I made the prop for my Morris myself, using an SD1 prop and a Sherpa prop. Totally coincidentally they are the exact same size tubing, though one is a cv joint on a UJ. I made a 6" long steel sleeve tube that tapped lightly into both props to line them up and I welded round it, also added a couple of keyhole welds on each tube.

I was wondering about the need for a slider joint? The diff and engine/gearbox are both bush-mounted to the chassis in the Sierra, so neither will move around much. I ask because my other car, a Triumph Herald, has a bush-mounted diff and solid propshaft with no slider. Is the slider to avoid stressing the UJs with movement of the engine?

there needs to be an amount of play to facilitate getting the prop betewwn the flanges, and the movement of the engine /box fore and aft under normal driving conditions will force a load up thru the gearbox output shaft , or knock out the pinion bearings
