I came across some dangerous rot in my chassis, just underneath the engine. The chassis is made of what looks like a cheap nasty folded metal sheets, and prone to rot.
Worried I could bend the whole chassis while sharp breaking ( yes, that bad...) I took the engine and gearbox out and the doors, and tipped the whole R4 in some tyres.(If you maintain some blocks under the hubs, and piut the tyres in the water gutter in the roor, it wont damage nothing.)
I then used some mig welder and welded some serious sections of thick metal sheet 40x5x0.5 cm along the main spars.
This substancially reenforced the chassis, and made in the process a very useful "skidplate". Everything is painted black and very difficult to see that this repair took place. I think i won in terms of preservation of the chassis. The MOT man is happy as well, and his little hammer sails through it everytime. (No, i aint gonna tell him...)
I write this so you can check very carefully if your R4 is suffering from the same, in this area which we normally dont have visual acess to.
Have a nice week.
