Engine assembly issue with 1200 upgrade...Need help

[Spartacus]

I bought the 1250 upgrade kit from NHRS. I was working on the engine tonight. I went to put the pushrod tubes back on and they won't fit. It seems the side of the tube is hitting the 4th fin down preventing it from seating correctly.
Comparing the new jugs to the original ones it seems the 4th fin comes out farther than the old one.

Anyone have this issue? Any suggestions?

here's a coupleof pics

the later 1200's case is wider. you'll have to file the fins to fit the tube, i had the same problem fitting big jugs on a 80" evo. Did you get new tubes and rods with the kit? They'll probably be different also.

no new tubes or rods


yeah I was thinking i'd have to grind it. Thinking about useing a Dremel

call Dan at NHRS he will explain what you need to do...Have fun keeping the seals on while seating the base plates for the tubes!!!....fun fun fun

I called Dan. He said no one has ever had this issue. He suggested grinding the fins

try to use files, theres not enough control with a dremel
