How is a jackshaft (#138151) secured to the frame?

Details:

How are the two bearing plates attached to the gokart frame? Can they only be welded or can they be bolted for making adjustments or replacing parts (such as bearings, gears, etc.,? I can see the need for future chain adjustments on the drive side as well as the need for adjustments on the driven side, but how do I go about it? Welding pretty much does away with adjustments, but I am not sure how to do it otherwise. Thanks for your help!

You would need to weld the bearing hangers to the frame. For future repairs you would replace the sprocket.

How many r.p.m. is it ok to turn these bearings

Details:

I am currently building a go kart with an oversized engine.
The problem is the engine has a reducer, (from a parts washer) I am speeding the rpm back up (potentialy with this kit) I am mounting my clutch on the end of this shaft because of the low engine final drive speed. I will be fabricating strong bearing mounting plates due to the torque. Just need to make sure I can spin these bearings about 5,225 r.pm. (that would be the max) Thank you for your time, James

The manufacturer does not offer an RPM rating on these bearings. These are light duty bearings and would not stand up to that high an RPM. The torque converter would engage at 2000 RPM and that would be the maximum recommended RPM.

There is no advantage of one over the other. It is just a different way of doing the same thing.

Azusa Jack Shaft Kit - 3/4in. x 14in. Length 3.9 5 7 7

DESCRIPTION IS WRONG! This product description states #40 size chain and it is not! It is for size #35. 40 and 35 are not even close to being interchangeable. They seam like quality parts but completely useless with the described #40 chain size. November 28, 2011

Kit fine, bearings Junk. Don't let the picture fool you into thinking that the bearings are usable. They are not. Otherwise it's a fine product. May 27, 2010

kit parts contained all nessassary pieces to complete project. excellent quality parts February 16, 2010

Jack Shaft Kit I was working on an old mini bike for my grandson and in trying to get everything put togeather we needed to do some changing so I ordered this shaft kit and was able to make everything work and made a boy very happy. October 19, 2009

Jack Shaft The jack shaft came just as expected and worked perfect for my application (Not a normal application for such a product as this). The bearings work fine, but looking at them I wouldn't expect them to hold a large load of weight. October 19, 2009

JackShaft Kit The kit was as described but the bearings were a joke. They looked like the type of bearing you would find on a "cheap" wheel barrow. I was afraid to use them. I had to turn around and and order a Pillow Block set with some decent bearings. This of course delayed the project. I wouldn't have minded paying a little more to get somthing I could use. The item description should have listed the part no. for the bearing that were included and offered an option for better bearings. You should also list a Pilow Block Setup in the same section of the catalog. August 11, 2008

jack shaft kit All of the parts were of good quality. I modified things a bit as my son built a custom cart from scratch. The kit parts worked very well. If you're going to do heavy off roading as my son does you may want to use heavier bearings but the ones supplied with the kit are fine for a track cart. October 26, 2007
