1955 Jaguar XK140 MC roadster (SP)
Total restoration
Restoration Log by Dan Mooney





 
Specification (briefly) for this project is as follows:

Total Team CJ restoration with numerous performance and reliability upgrades.

 
 

 

Your chassis has now been repaired, blasted and powder coated!



Cutting out rusted area at rear of chassis












Trial fitting newly fabricated replacement panel











Welding repair panel in place










Inner surfaces acid washed and coated with wax












Chassis number by right hand rear engine mount










After sand blasting back to bare metal, the chassis
has now been powder coated












Time to start rebuilding and installing the
suspension and drive train



The first two photos in the sequence below show how we modified your oil pan baffle. Originally the XK baffles were welded to the pan, which made it virtually impossible to properly clean the bottom of the pan. We cut the baffle out and install brackets with threaded nutserts down the sides of the pan, allowing the baffle to be unbolted to properly service the inside of the oil pan.
