Cool Video Wildman. We have about the same amount of snow here in Milwaukee. Looking for temps in the high 40's this weekend, so goodbye snow.

Attached are pics of my new toys, yet to be worked on.

I like those projects... about the same as my waiting list.

Great project pictures and winter videos! I'm still working on fiberglass repairs on my Tricart over the winter, and it's coming out fairly well. The Max VIII has been occupying most of my project time, but in the lull's, I lay another layer of fabric, sand, repeat.... The next couple months will probably see the fabrication of the new driveline and rebuild of the parts I'm reusing. the engine, mount and associated parts were all missing, so it's a grand opportunity to make some minor mods.

Just bumping this thread up. I just joined and will be looking for all the info I can get on the Tr Cub's. I have two that have been in the family since new from what I've been told. I grew up on them. Both are complete but need to be cleaned up and I do need some parts. Hope to get some great info!

Hyper... Welcome to the board. Us Trikers need to stick together on here.

I replied to your email with some more info.

Unfortunately, there's not much for parts available anymore. Some of the common items like bearings etc. are still active parts in the New Holland system under the same part numbers. Many items were common go kart and minibike components of that era, so some stuff came be found at those sources. Everything else you have to make or have made.

Looking forward to seeing photos of your Tricubs posted here.

Thanks Wildman and thank you for the email. The part I need most is a differential. I just got off the phone with a local chrome re-plate company and will hopefully get the handlebars over there as soon as I can. I'll get some pic's up in the next day or so.

Hand onto your checkbook when you get that plating done. I had all the Tricart, Tricub and Minicub handlebars, brake levers, etc replated, but Ouch! Fortunately there's not much chrome on those things.

Well I've got most of the one tri cub disassembled. My current dilemma is the rear axle/differential. All the bearings will need to replaced and the one jack shaft has a slight bend to it along with the idler gear. The bearings being bad in the rear axle is what took out the diff. So if you plan to run one of these make sure the rear bearings are good because so far finding a diff is becoming a challenge. Here are some photos of my two, I posted a bunch!!



















Here's my current situation. An old repair due to the differential failing. This was caused by bad rear axle bearings.

[HyperXCF]

Just spoke with my local New Holland dealer about the rear axle bearings (41448). They are available and cross to a Case IH# 56499R92. About $20 a piece.

Well need to edit this as I found the Napa replacement part numbers for the rear axle and jack shaft bearings:

Axle-New Holland #41448 Napa# RA014RRB $17.39

Jackshaft-New Holland #66006 Napa#RA010RRB $16.69

Thanks to Wildman the idler sprocket at TSC could be part# 1182009. I haven't checked that yet but looks like to be the one.

Gas tank is a Briggs & Stratton #290816. The common metal gas tank that came from 8HP Briggs. Not cheap! Lol

Seems like a pretty inexpensive repair. That's cool that the parts are all still readily available too.

Here is a link to a differential axle that Northern Tool sells for go karts. It might be just what you need.

I know somebody else that was trying to retrofit that axle into a Tricub. The biggest issue is that the original axle is 7/8" and Northern axle is 1". He was going to try and find 1" bearings with same OD as the 7/8", so he could use the same flanges and not need surgery on the frame. I haven't spoken with him in a while, so I don't know if he was successful or not.

I was able to get over to our local small engine repair shop/junk yard. As soon as I showed a pic of the differential I was looking for they knew exactly. They said that Toro small riders used them a long time ago and that was a common axle assy used in homemade gokarts. Well needless to say they had a assy. with the tires. The assy had one short axle and one long. I needed another axle because my original one could not be used due to the previous repair. So I pressed off one of the diff gears from the short axle. Wow, that was really one there but came off with no damage and I will be able to press it back on to my other good axle. Now the other Toro long axle is about 1 1/2" shorter than the original Tri Cub axle. It still goes into the wheel hub a safe distance but I might have it lengthened just to make sure. I've been busy with other things but at this point I have and located all the pieces to completely get both of these Tri Cubs back together in working order. Now time to get parts washing!!

Inside of the diff. Not very heavy duty feeling!

[wildman]

That's cool to have identified that diff. Do you know which Toro family of mowers that they came from? If those bevel gears are only pressed on, you should be able to make axles (or have made) any length you want from some basic 7/8" shaft mat'l.

[HyperXCF]

I have not yet indentified what Toro(s) they came from. I looked around the lot hoping to find a complete unit just for that but they didn't have anything that old. As far as the axles I will be able to use what I have with no issues which is good. But your right, it would be easy to have some made.
