Pretty much all the modded drives now are used drives...that was waaaay back when Dan had an inside man at the Lehman Trike plant.
Anyone??Hi guys, I've just done this mod on my c50 (vs1400 drive) I had the c50 shaft milled back by 3/16th at the end and shoulder as per the photo at the start of the thread and I had the stock spacer milled down 2mm, Everything is working great and I'm loving the bikes longer legs and more relaxed cruising ability, I was wondering if anyone could help with a question I have? What are the stock lengths of the 1400 and 800 spacers before being milled down to 2"7/8 Thanks.
Thank you so much you were very helpful :wayhappy:You use the spring from the 1400 drive, you can use either spacer even though they are different and yes you have to machine the shoulder back below the splines otherwise you will jam into the coupling and damage the receiving splines. You need free movement in and out .
You will also need the oil/grease seal for a 1400 drive and ensure you generously apply moly 60 grease to the splines at both ends of the shaft as well as the splines on the inner hub of the wheel. Apply an rtv/permatex sealant where the final drive connects to the frame/drive shaft tube to keep water out.
I am sure you will be smiling once you get the new drive in and take your first spin on the highway.
