Stud through heat exchanger

[twin whackas]

My buddy had a stud pull through his track and gouged the front heat exchanger. Tried to have it repaired and it is still leaking. Does anyone know if you have to pull the motor out to remove the front heat exchanger out and replace it?
Thanks
Mike

The motor can stay. Need to pull subframe and one of the cast side frames, I pulled the chain case side.

pulled mine out two weeks ago to have it welded, i pulled the motor and the clutch side cast frame. yammie rivets are a must for reassembly.

Cold weld! works like a dream. Multiple miles on mine with fix, no problems.
