Interstater (NH TS-100A , 115A , 125A & 135A Asy. Manual) 06/04
Modify Exhaust on Tractor:
1. Modify Tractor Factory Exhaust
System. The Exhaust of the tractor must be
modified to move exhaust (muffler) in closer (8-1/
2" Closer) to the hood of tractor to give the
Interstater clearance when wing is folded into the
transport position. This should be done before
the wing mower is mounted.
2. Remove Old Exhaust System. The stock
factory muffler is removed first, this will be saved
as it will be reused after the exhaust pipe to turbo
has been changed.
3. Remove Existing Exhaust Pipe to Turbo &
Existing Exhaust Mounting Bracket. There are
four socket head bolts that hold the exhaust flange
to the turbo, these will need to be removed com-
pletely. There is a stock mounting bracket located
at the outer corner of the cab that supports the
exhaust pipe. This bracket will be removed also.
(See Figure 2). Lay the Bracket and exhaust pipe
aside as the kit will include replace Pipe, Bracket
and Fasteners.
4.
Exhaust Relocation Kit. The new Exhaust
pipe, mount bracket, clamp and flange mounting
bolt will be included in Exhaust Relocation Kit P/N
