    Shovelhead 4-speed Rebuild

    I have a 1984 Shovelhead FLH 4-speed, built in June '84. Chain primary, belt final drive. 1. I have ordered and received 601-050 Mainshaft Support Bearing which is described to fit 70-84 BT 4-speed. The OD of 601-050 is 2.002 inches. The original support bearing in the inner primary is 2.045 inches, making the 601-050 too small. In addition, I have received 601-003 James Primary Cover Gasket Kit which contains the Inner Primary Mainshaft seal. This seal also measures 2.007 which is too small for the inner primary. Question- Is it possible that my inner primary is a model change as this bike was manufactured near the end of the model year? Does J&P have a Mainshaft Bearing and Seal that will fit this inner primary? 2. The existing tranny Mainshaft is an Andrews P/N 208800. This shaft is 13.75 inches long, approx. I need to replace this mainshaft. Does J&P have a part number for this shaft? Thanks.

    that andrews number crosses to our 620-797, which says it is for 1985-86, so i'd say yes, yours was built with 1985 parts, which is not surprising, 1980-85 were nightmare years for parts guys, no rhyme or reason to some of the things harley did. the seal number crosses to 6100105, and i believe 600-855 would be the correct bearing, but i cannot independantly verify that. however, it does have the same outer diameter, but the inside diameter is smaller than that of the seal

    tpgulch, i happen to have the same bike as you and installed main bearing 601-050 in the spring and it was a perfect fit. 1984 shovel flh, belt final drive. go figure. I also used the cometic brand primary gasket kit and everything fit perfect. guess i was lucky.

     Take it easy or any way you can get it.

    Yep, sljb I think that's the way its supposed to work. If I ain't mistaken, I think mine is one of the last ones built before the Evo and 5-speed. Probably used some '85 parts to finish it out.

    Re: Shovelhead 4-speed Rebuild

    Steve, I've received the parts recommended. Mainshaft 620-797 is perfect, as is 600-855 bearing. However, the seal 6100105 has too large an ID. The OD of the seal is 2.057 which is close enuf, but the ID is 1.20, too big. (shaft size is .985). So, I have the seal from the James kit 601-003 which has the correct ID but too small OD, and the seal 6100105 which has correct OD but too large ID. I need a seal which has 2.050 OD (approx) and a 0.98 ID. Any suggestions?

    i don't have a micrometer, but i pulled 6200060, which is for the early FLH, and the 85 fx with rear belt drive, and it matches your description. fitment doesn't match, but it looks like the right one, about 1 inch inside, 2 inches outside by my tape measure
