Chassis work begins

Since my last post I've been working mainly on my chassis. I got it back from sand blasting and promptly gave all the 'good' parts a coat of epoxy metal paint. It claims to be able to be applied straight to clean metal. I figure sandblasted is pretty clean so I went with it and it's come up well. I used Dulux Metal Guard, Satin Black. I'll give the whole thing another coat once all welding work is finished.





The paint looks quite glossy while it's wet but it dries flat.

First repair job was the front of the chassis rail, I cut the square cap from the front of the rail, removed the dirt and debris, wire brushed the inside and splashed some rust converter around inside. Followed by welding a new square piece of steel on the front.


Bulkhead outriggers were next, passenger side was repairable so I chopped out the swiss cheese sections and the angle brace. Cut new steel, welded in, then linished back to smooth. I used a piece of 30x30 angle iron to replace the brace. The original was a piece of folded steel, so I smoothed the sharp angle off the new piece for the original look.




Drivers side outrigger was beyond help, so I took some reference measurements and cut it off. You can buy replacements but as it's a pretty basic piece of fabrication I made my own. I cut the square blocks off the original and welded them to the new one, so it looks authentic.





I have only tacked it to the chassis, I'll fully weld it once the bulkhead has been fitted, just incase there are alignment issues. Although given the variations from side to side on the chassis, I guess you could drive a truck through Land Rover's tolerances, so it should be fine.

Next was the rear cross member, the most common area of a Land Rover chassis for rust to inhabit. I considered patching it, but it looks way too rusty on the inside, and it's made of all sorts of intricate folds so would be hard to replicate the parts. So I wanted to remove the cross member without disturbing the chassis rail ends (which also need repairing) so that I can measure their original length to re-create them. Before cutting, I made a jig so that a new cross member can be fitted in the exact same place.


Took a lot of perseverance with the angle grinder, but I got it off without cutting through the chassis rails, well what was left of them. I then made a cardboard template to give the shape and length of the ends of the rails. Then they were cut back flush with the spring hangers. The reason I'm doing this, is so that I can use a new crossmember without the extension rails, as the type with extension rails make the repair really obvious as it slips over the existing chassis. This way my repair can be more or less hidden.

Chassis work is on hold now until I can get my hands on a new crossmember. Still unsure whether I will buy one locally or from the UK. Still need to figure out what is cheaper.

While all this chassis work has been going on, my order from LRdirect.com arrived with all the parts to start assembling the rear axle.




'Distance Pieces' shrunk onto the stub axles using an induction heater.



Diff centre fitted with new gasket. Pinion seal and mud slinger also replaced. I need to wait until the axle is back under the chassis with some weight on the wheels, so I can torque up the pinion nut.

Then assembled and fitted the hubs and brake backing plates. I haven't set the hub end float, as they may need to come back off to fit the brakes, but it's good to have it all together loosely, just so the parts are all accounted for.

Leaf spring refurbishment

Spent Queens Birthday long weekend working on making the leaf springs presentable. They were in pretty bad shape, a lot of rust and pitting but they still have a reasonable curve in them so I'll take a punt on re using them. If I had the money I would buy new springs but if I was replacing everything this project wouldn't be happening.

So first I stripped the spring packs apart. The leaves were so rusted together that I had to use a hammer & chisel to separate them. Next was the challenge of removing the spring bushes. I made a puller with some M12 threaded rod, some tube and a boss I turned down to a diameter slightly less than the bush.

  
Once apart, I buzzed off as much of the rust as I could with a wire brush on the grinder.


I then applied CRC rust converter to help with the remaining surface rust.

And reassembled and painted.



Another spring related job that needed doing was the spring plate/shock absorber mounts. The original pins were really worn and beyond repair, due to the shock absorber bushes collapsing. I dissected them and cut the pins from the plates. Cut some new shafts from 3/4" stock and welded them back onto the plates. Should be good for another 40 years



I'm expecting a package from www.lrdirect.com any day now, which has all the seals and gaskets etc for me to reassemble to rear axle, so expect a post about that soon.

In other news, I've put the engine on an engine stand so that I can move it around.


And the chassis is off to the sandblaster tomorrow


Stay tuned..

Long overdue update

It's been over a year since I posted here so I thought i should bring the blog up to date, incase anyone out there actually reads it! ...
