Inner Primary Replacement Project Complete : V-Twin Forum: Harley Davidson Forums

Well, it took me about a week but I finally got my new inner primary on yesterday and was able to finally get the LowRider back on the road. I'm really impressed with the new inner primary from Cal Products. This thing is much more heavy duty than the OEM - check out the pictures. You can see how much more thick the walls are over the OEM. It feels like it weighs about twice as much. You'll also notice there are no oil feeder holes in this new primary. If you want to run the original oil lines in/out your primary then you'll have to drill a couple holes. Installation was a breeze - this thing bolted right up and all guts went in without any modifications.

As for the overall project, there were a few minor problems along the way but nothing major. The big pain was getting the starter bolted back on, because one of the bolts is in a very awkward position and tough to get started straight.

Good job MTG. Yea dude, the thickness of the walls is very noticable.

Didn't you say you had to bring it to a shop for part of the install?

Looks good.

Very, very cool.

Just curious, what year is your scoot? Looking at your pic of all the pulleys installed, I am jealous!. Mine does not have the idler setup, and your front pulley is definately different from mine. Mine is an '83 FXSB and has a factory belt pirmary setup. I really like yours much better and want to know how I get one.

Just wondered where you got the setup and about how much it was?

Thanks,
Michael

Nice job. The front belt drive looks like a Primo based on the idler.

New Ultra nailed it - it's a Primo setup.

MadMike: The bike is a 1980 Low Rider (FXS). The original primary was chain drive. The guy I bought the bike from installed this belt drive. You can get them through most of the aftermarket dealers like J&P Cycles. It's a 1 1/2 belt (11mm). I think you can get a Primo setup like this for $300-400. You can use your current clutch plates.

JetDoc: There's a fork assembly that's activated by the solenoid and attached to the starter drive. The fork is held in the primary by a long slotted head bolt that's very difficult to remove unless you have a impact driver. If you look on the outside top of your inner primary, right under the oil tank, you'll see the head of the bolt I'm talking about. The new primary also doesn't come with a bearing for the transmission sproket shaft. The last thing is the idler. I'm not sure if the bearing is pressed in our what - maybe NewUltra can shed some light here, but I didn't want to screw it up, so I just let the shop put it in.
