Thanks for helping out Don! I would like to compare the ones I have in the trailer to yours to check the angles.
Don,
AM55357 is the 44 degree helix for the 82-84 Liquifires, (>-190,000). "I think" the AM55070 is 38 deg, as it fits the 80/81 Liquifire that came with the Comet 102. I want to compare to Pat's helix since I don't have any parts books with me, and jdparts.com does not list the helix angle for the AM55070, but does show the AM55357 as 44 deg.
See you guys in St. Germain!

Joe, the Fine Tune Manual is the greatest for these type things. They list all the helixs

Is the only difference the bushing material?
Are they dimensionally the same and can be interchanged?
80 Liquifire (purchased 1996 ~ Running)
80 Liquifire (purchased 2010 ~ Running....Now)
80 Liquifire (purchased 2011 ~ Not running - I officially have a problem now)
83 Snowfire (purchased 2014 father/son restoration project)
78 Spitfire ~ sold (should have been shot for this)
I think it's safe to say yes. The "AM" indicates an "assembly" (more than one part together, in this case a bushing and a cast helix M68534) so since the casting is the same I have to think the part number difference is based on the bushing. I'm not a JD engineer but I did stay at a Holiday Inn Express last night.

I just wanted to say "Thanks" for straightening me out on the helix angle for the 80/81 sleds. I never fail to learn a new detail about these old girls, even helix angles.
And yes, I quick trip to my fine tune manuals, (that I do have in TX) would have answered that question. Glad you got it taken care of Don!
