jackshaft

Looking for quality jackshaft and hub bearings. Part numbers from a supplier would be appreciated. Thanks.

I have a new jackshaft kit that I won't be using. Shaft is 9 1/4" long, and the gears are 13 and 18 tooth. All parts are new. Looking for $40 shipped...and I always like me some trades!

Just my take on the dirt bug jackshaft, using a Comet back plate that didn't end up being used for our go kart. Used the angled holes to clear the muffler, but had to raise the engine up with a piece of 1/4 aluminum I had. Just so the back plate wouldn't hit the motor mount plate. Have a 22...

Okay guys I need some suggestions. I am building an older bike, don't know the manufacturer, most likely off brand from wards or something. I am to the point of designing the driveline. I am working with a 3.5 briggs with 11 clutch sprocket and 60 tooth wheel sprocket. Due to alignment problems...

My original Jackshaft assembly was the one part of my bike that I always looked at with regret. It really was a bad design and was 'flexy', which caused my chain to throw a couple times. It didn't take long before some torque was applied to the wheels and the mounts bent. I was actually glad...

Hi, I am a new member at OldMiniBikes. I have a question. I have a Baja minibike (not the doodlebug) its is the mb 165. I took out the old engine and bought a new 212cc predator engine to replace it. the jack shaft is pretty old now and I wanted to take it out entirely and make the chain going...

I have a PMR Jackshaft and a Briggs & Stratton engine pictured below. The bolt pattern on the PMR doesnt match the value cover on the engine. Even the center hole on the PMR is to small for the small outlay near the shaft. I can easily expand out with a drill press but I am wondering about...

Tireless research by the Powell experts have shown these to be an accurate substitute for the originals. Even the brown seals are a match. The same bearing fits the wheel hubs and that goofy one-sided jackshaft assembly. High quality made in the USA bearing...something of a...

Hi everyone so a few years ago i started restoring what i believe to be a sears mini bike but some personal issues have gotten in my way. I am finally now working on the bike again i have almost all my egg in a basket but i can't seem to figure out this jackshaft gearing as it was missing as...

so guy how do you put on a bonanza chain guard bracket

I am looking for a jackshaft that requires no welding . I'm looking for a jackshaft for my boonie bike. I was thinking of just going down to a machine shop and asking how much it would be to make a copy of an original boonie bracket. I was wondering if there's anything else out there ? I saw...

Looking for a long (10 3/4") Bonanza jackshaft for the 1400/1410 style bikes used with the outboard sprocket. mine is still useable if I reverse the way it sat (the bearings ate into it a little bit over the years) but would like a new one, and I dont think I will be able to make the cuts for...

I'm needing a jackshaft nut is there anything special about this nut, Is it something I can get at a hardware store? I'm seeing prices as high as 13.00 for it. I bought a used Mb165 and I'm replacing the jackshaft the one on it has had the sprockets welded on and I have not received the new...

I'm setting up the jack shaft sprockets on my Tom Thumb. What combination do I need.? Please don't tell me that technical stuff:laugh: I have a 11 tooth clutch and a 60 tooth sprocket. I don't need to go fast........Just putt putt along. I have in my stash a 11,12 and 13tooth small...

Starting a ground up project with a custom frame for my son. I plan to use a predator engine with a tav. Assuming I will need to use a jack shaft, I will also be building a rear swing arm. What size sprocket should I put on the jackshaft to keep the ratio 1:1 with the driven clutch pulley from...

Which would you rather have on your mini comet Tav or PMR Jackshaft Kit and why.

Can u do away with the jackshaft on a mtd mini bike

Here's a set of Jackshaft Plates. Bearing hole is 1 3/8", Plates are 1/8" thick. the mounting holes are slotted 5/16". These are almost the same as the Comet brand. They are New Old Stock. They'll work on Trail Horse, Roper, and other frames already set up with the tabs, or you can weld your own...

I bought a 1966 Taco 66 that the restoration had already been started. It is missing the jackshaft and all I got was the four bearings with retainers, one small and one larger sprocket and three small spacers. Since I did not take this apart, I am not sure how it goes back together. I also have...
