DB1 questions :)

[Ross]

I've bought a used DB1 and have a few questions to ask.

I've had to change the drive shafts as there were very warn, when rebuilding the cari noticed that the RHS rear arm was sitting lower than the LHS. I've measured the length of the shock bodies,shock shafts as it sits on the stand, the top plastic caps on the shocks and they all match each other,I'm baffled as to what can be the problem. Can some one help.

The rear front hinge pin holder (on the rear end if that's not clear ) was loose and moving, is this a common issue or just down to screws not being checked. Also when removing the rear end the anti squat shim came off as well but there were also 2 washers,now these look like they go between the chassis and the gear box, is that correct.

I would like to print of diagrams and part number listings for both standard cars used for the kit, i had a look on the net and couldnt find anything that help me,does anyone have a link for these please.


Cheers
Ross

Here some pictures of the shocks








The drive shafts are also equal in the out drives






And here's a vid of the holder moving

Measure shock bodies, should be 38mm

Also there are different rear wishbones avaliable, so take off and check the same.

I find the correct ones have a little M on the outside near where the hub mounts

I'll have a look at mine.

RE diagrams, I'll have a look through my mailbox, but if you email tony@rudebits.net I'm sure he'll send them over and provide assistance.

I did measure the bodies, there both around 38 mm, I has read no one of the threads that some one mentioned there are different sizes so I checked.

Just checked that the arms have an "M" by the hub and they have .

Cool would be good if you've got some diagrams,if not ill email Tony.

The two spacers are probably from the top deck, they go between that and the rear gearbox casing.

Normally the height difference would be from the incorrect shock caps bring fitted, the two types do look very similar, either that or the o ring seal in the top of the shock being on the wrong side of the shock top. (It should be under the top so it's flush with the top of the shock)

The car looks familiar.. If its Neil's old one it was well looked after so may have just got a rogue part fitted.

The alloy wishbone holders do come loose, some weak patch lock will do the trick..

[Adam F]

Oh and check the top mounting screws are straight and the shocks have an equal amount of thread showing.

Foleys comment jogged a memory. One of my shock caps got damaged and replaced a few weeks ago and i got given a replacement. It may be they are slightly different.

Just checked the top deck,its sitting parallel with the battery's and straight
I did check the shock caps, the plastic top looks tone sitting in the Ali cap Ok.

I thought that may be the case with the holder,ill keep an eye on it.

Is there two 2mm spacers under the rear of the top deck? If not there should be.

Other than the things I have mentioned I have no idea why they would be different..

Have you stripped the rear shocks to check for spacers inside to limit droop?

Same for the shock bottoms, there are various lengths...

[Chris-S]

Also various lengths for the plastic shock tops.

[Adam F]

Looking at the pic from the rear it looks like the LH shock top is a shorter one (zx5 instead of RB5). (the gap from the tower to the anodised shock cap look different)

[Adam F]

This one, check the gap on the LHS compared to RHS...

Ok I'll check tomorrow to see.

If I put them there it will sit at an angle. Could you post a picture of yours .

I'm going to strip them tomorrow but the shafts extend out of he bodies the Same amount. I haven checked the bottoms, ill do that tomorrow.

[Ross]

Looks like its my dodgy pictures, I've just measured them and there the same

They both look to be the same Chis

[Chris-S]

Tried swapping the shocks side to side? If the problem stays on the same side, it isnt the shocks

Good call,try that in the morning.

The overall length of your rear shocks should be 100mm external. There are three lengths of eyelet ( wishbone end ) if you're using the short ones you will need to unscrew them a few threads to achieve this length.

[tomtom]

Yep, was thinking the same thing and my iPad gone out of battery.

I think your RR hinge pins bock is bent (check inserts, should be F).
Bent one once on my FS2 so it can be done

I also got to be carefull when screwing this RR block as with no shim
between this one and the chassis the fit was tight and could be fit at an angle.

Everything else looks good from where I sit.

Could also be internal shock limiters if everything else mentioned checks out OK.
