Hi All,

Anyone know where I can get a galvanised chassis for a T plate Jimny? Seems like the salt has got to it.......

Cheers,
Dave

Nobody stocks them. Your only option would be finding a good chassis and getting it galvanised yourself. But it would be cheaper to cut your losses and buy another Jimny that wasn't rotten. If the chassis has rotted, the body won't be far behind and you can't galvanise that!

I'm surprised that the chassis has rotted ahead of the body as Suzuki chassis are quite good but the body shells are not.

As has been said, getting a good used one would be the answer but I wouldn't go to the time and expense of galvanising it as it will out last the rest of the car making it uneconomical if you are prepared to scrap it later due to body rot.

You will run into vehicle identification issues though. As long as you grind off the old chassis number and stamp it with your original one I don't see the issue as you are changing it like for like - just as Landrover folk do with new chassis and there's nothing dishonest about it if the donor car is not stolen.

I don't believe that is legal, as I understand it its illegal to alter the chassis number therefore you should stamp the new number next to the old one; the law is intended to ensure that the replacement chassis is traceable. A new replacement chassis is different because it will be provided without a number.

My understanding is, (and i'm happy to be proved wrong). The registration and number plate stay with the chassis, not the body.
To grind off a chassis number and re-stamp it, Is creating a ringer.

It's been fettled just a tad.

A chassis swap alone won't give enough points to retain the number plate from the vehicle that donated the chassis. Technically its not a chassis number but a Vehicle Identification Number (VIN) so it stays with the vehicle.

Thanks Guys,

This Jimny is for a project but not an off roader.....it will be chopped around quite a bit as things progress. Having failed the MOT I need to get it back into a roadworthy condition to demonstrate the finished unit.

The MOT failure was mainly chassis based - up until 2 years ago a replacement chassis was available from Suzuki as a spare part - sadly they only service product in this area up to 10 years old
provided you can demonstrate to the DVLA that you purchased the new part they have no concerns with you replacing the chassis.

The VIN Plate is the identifier of the complete vehicle,
everything is related to that VIN, engine number and so on.......by replacing a spare part you are not changing the identity of the vehicle, just a spare part and as the page from the catalogue shows the chassis is a spare part.

I've built LR several specialist units for export, some with a changeover to LHD and have never had an issue with the DVLA over replacement chassis

Crickey, you've dug up an old thread there!

Not really as generally the chassis don't rot, just the shells, as I said in 2016!

For anyone reading this and considering to galvanize a used chassis:

Yes it is possible to perform a hot dip galvanization of a used chassis. I considered doing that at one point, so I even contacted a company which performs hot galvanization of metal parts.

The process consists of dipping the chassis in a pool of acid first (to eat away all the dirt, rust, paint, etc. and to etch the metal), then dip it into a pool of acid neutralizer, and then in a pool of hot molten zinc at about 450 C.

They told me that small truck chassis are susceptible to warping at such high temperatures and that I would have to sign a document where I accept all the risks of the procedure.

There is an alternative process called cold galvanization which is performed just after sand blasting the chassis. It does not involve any acids, and the zinc can be applied only to the exterior surfaces, so the interior of the chassis will not be treated.

All in all, it does not pay off. Better to obtain another better chassis.

Bear in mind that the average truck chassis is often a open c section design and is intended to provide some flex from one end to the other. A 4x4 chassis is a closed box section with numerous cross members and isn't really intended to flex much at all. Hence why it's a common practice with the old defender to hot dip galvanize. Equally though a land rover comes from the factory pre corroded unlike a Jimny.

I know Citroen 2CV chassis' got galvanised, and it was possible to buy a new chassis in a galvanised state, but I think they were a 'C' section rail as are many pre-war cars. Some pre-war racing cars had sections welded in effectively making a boxed section for bettter tortional strengthen. These often had large lightening holes cut into them to reduce weight

I haven't heard of anyone galvanising a pre-war chassis and I've been involved with pre-war cars since the 1980s - these cars are 80+ years old and still being dug up from old outhouses where they've been stored in often unfavourable conditions - they get sandblasted back to bare metal and the usual paint finishes applied (I favour two-pack paint) . Any cross-tubes get pumped full of Dinitrol or Waxoyl and they should be good for the next 80 years.




Any rotten parts of the chassis rails are simply cut out and replaced - same with any cross-tubes.
The hardest bits to replace are the castings that were riveted onto the chassis in which the cross-tubes fit

Bent chassis are straightened using heat applied at various points - but I imagine that must be a fairly specialist job as you'd need to fully understand what your doing in order to acheive a straight chassis


IF IT AINT BROKE, KEEP FIXING IT UNTIL IT IS
