Odd Gen Tray

Just got home and ready for the first project.  When trying to find the thump in our gen set I found a badly deteriorated rear mount.  I am going to pull the set and do a mod, Marks MAZ including powdercoat, replace the mounts and isolators, and the insulation as well. 

Reading the other posts I saw that my tray does not have the same pattern as the other 8k 270s.  Should I replace it, bolt plate over it or weld?  Was this pattern found on other trays?

Thanks

Just curious, what's the story with the two loose wires on the lower right in pic # 1 ?

Those are from the resovoir.  It was crimped completely closed with a mudobber attempt on the far end.

Yes it is clear plastic from the resovoir.  The overflow end was crimped shut the other end was blocked with mud.

Bill any good reason to cover those openings?

Your photos look identical to ours.  Not sure what you are concerned about.  We painted generator, tray bottom and top, put new mounts and isolators and new foil over original insulation.  But we did not see any reason to remove generator or tray, as we could just pivot generator about mounts while painting.
Did run into an issue...  found radiator bottom isolator bolts not glued to rubber isolator, which probably allowed radiator to move about a little during engine vibrations.  The 'failed' isolators did not cause any problems and the broken isolator was only found when we replaced them with new ones purchased from Power Tech.  Well a short time later, one day we found the bottom of the radiator had broken its solder joint and leaked coolant.
Determined that the new isolators did not allow the rad to move about and the rad bottom could not take the vibrations, putting more pressure on the soldered end, which may be the weakest part of the radiator.
If we had left the broken isolators in place, we would have been better off.
Our fix was to remove bottom two isolators and support the radiator bottom at its strongest point with new rubber mounts under the tank.  That is, after we had the radiator bottom tube soldered at the leak breaks.
Bottom of gen compartment drops off by removing 4 fasteners, allowing complete access to back of generator from bottom.  Sitting with our upper body behind gen, we did find a very small oil leak at the oil pressure sender, that we did not know about.

Thanks for your insight Barry.  Since I am unfamiliar with the need to separate the radiator, I was going to do Marks modification as a preventive project.  My concern, after seeing many of the pictures, was that I may be dealing with a repair or replacement that would require a different approach since the tray was stamped for a different product.
