Came in the door as a 3400 freebe. The p/c was fried big time. Got a used 3800 P/C.
Then found the seals were shot as well as the main needle bearing were shot.
Ended up as a full rebuild including paint with clear-coat and a rim sprocket with 20" B&C.
The chassis is a later version with large diameter oil cap and hex rear iso mount and 1/4-20 screws, unlike the early thin round tube & 10-24 screws.
