Motor Trike questions

Post by alwrmcusn »



I have a 2008 GL1800 MotorTrike.
I found, downloaded and printed a MotorTrike document addressing some maintenance points. I am not very mechanically inclined and have some questions.
The document (a portion of it) is included below:

2. Grease rear universal joint every 5,000 or when the oil is changed.

3. Inspect and tighten all jam nuts. Make sure a medium grade loctite is used (Blue).

4. Grease two swing arm pins on the shoulder where ladder bars rest every 24 months or every 15,000 miles.

5. Use a dry silicon spray and/or white lithium grease to protect heim joint from wear. (3M makes this product and can be purchased at any auto supply store.)



My questions are:
What grease do I use on the universal joint?
What is a "jam nut" and where are they located?
What is a swing arm pin, where is the shoulder that the ladder bars rest on?
What is a "heim joint" and where is it located?

My suggestion? For the first oil change and U-joint greasing, get it done by a friendly shop, that will let you watch. Have the mechanic show you these points, even if it costs a bit extra. The actions are fairly simple and straight forward, but a picture is worth a thousand words. Any good grade grease in a tube will work for the Universal joint (U-joint), however a synthetic bearing grease is probably the best choice. That way, if you forget to grease it at the 5K mark, it will be okay.

Thanks for the prompt reply. I believe I can do the actual "work", but I still need the other questions cleared up for.
I usually change my own oil & filter, I can probably even do my brake pads but some of that terminology is new to me.

Okay, then I can help with a bit of what you asked. Any normal tube of grease will work for the U-Joint, jam nuts are either nuts with a plastic coating inside to keep them from backing off, or two nuts on the same fastener which are tightened against one another. A heim joint is very distinctive and can be seen here:

You can get a service manual for one of the Motortrike kits here: It may be similar enough to help.

Thank you again for your reply. I assume the heim joint is a part of the MotorTrike Razor conversion of course but where under there and what does it do? Is it part of the axle, the drive shaft/U-joint, suspension?

According to the manual for which I sent a link, the heim joints attach the ladder bars at the motorcycle frame and at the trike kit axle, so I would think they are stabilizer ends. What they do is allow freedom of movement in several directions so as to allow the ladder bars to twist rotationally. It is explained on page 11 of the 91 page Motortrike Service manual at that link. Just right click on the link and choose "save content as". It will save to your computer as a Motortrike Service Manual.

Thank you, I'll give that manual a good read. I think I'll need to go to Harbor Freight and purchase a grease gun also. :)
