Rear Beam Questions!

[monkee87 2]

Right, I'm just about to start rebuilding my 309 beam. I had 2 beams which I took to pieces to make a good one out of the 2. One was off a base model so was in good condition and I'm wondering if the trailing arm shafts are going to be okay to re use? I'm not so sure they are and I don't want to ruin my new bearings by using them if they're crap. It's all a case of saving a few bob!

Don't suggest turning them 180 degrees, I don't have the means to do so.

 

Also, I've found a Partner van in my local scrappy which I might take the torsion bars off for my 309 beam. Would a 21mm spanner fit over the 21.3mm bars? I don't have anything to measure them properly... Probably a really stupid question... Haha.

 

 

The help is very much appreciated!

The last two pic's don't look fantastic to me but can you feel any ridges when you run you finger tip around them?

 

If you can then they at need rotating 180' or are scrap imo.

 

If you can fit a 21mm spanner over the partner torsion bars they aren't 21.3mm imo.

Bottom shaft is certainly scrap because of the corrosion.

 

Top one subjectively looks OK to reuse judging from the photo, assuming that's just polishing (rather than pitting) on the inner bearing surface.

The second shaft isn't flat if that makes sense, but it's not ridiculous. Maybe I will just bite the bullet and buy some new ones. I don't have the means to turn them 180' unfortunately..

 

I can't fit a 21mm spanner over the torsion bars, so I kinda guessed they were 21.3mm. It's a P reg van if that makes any difference? There were 2 others there which I could fit the 21mm spanner over the bars.

Also, would it be worth using VTS/ZX trailing arms? It's a road car so I guess there wouldn't be any advantage to doing so.

It's not pitted, all I did was wipe the grease off of it to take the picture. So could I possibly get away with only buying one shaft?

Yes i'd go with that, certainly from the pics one looks ok and the other possibly suspect, so you'll get away with just buying the one!

am i overlooking something obvisious here. because if you have the ability to replace the shaft then how do you not have the ability to rotate it 180 degrees?

I'd replace both if keeping the car,

If I replace them I'll get someone to press them out, don't see the point in getting someone to press it out and back in again with a crappy shaft.
