My only thing I think I would have done differently is make it so the shaft would be thicker till it got to the pulley so it could run up against something, but I assume that was done because you don't really know where the pulley has to ride yet. Exactly. I have no idea where it's going to sit. I'd like it to be closer to the engine and then I could shorten the shaft. It looks like if the pump sits in that far though, it would be pushing the outlet barb close to the engine and make pretty much any hose kink trying to bend as needed. Really haven't spent any time on that part yet.

I got the Central Machinery 20 ton press setup yesterday. Pretty happy with it. It looks like they have improved it since the reviews that I've watched. The biggest complaint was taking so long to get the ram down to the work so lots of people installed an air hydraulic jack. Now they've changed the layout and in the top position the ram is about 1" above the arbor plates. Assembly is also different. Now the majority of the frame is pre-assembled and welded, instead of being all bolted together by the user. Pretty much just stand it up and bolt on the feet for the frame assy. Then install the jack and ram and press table. I did 1 mod immediately. The pins to hold the press table can slide out either way. I drilled near their ends and put pins in. Probably not something that would ever be a real problem, but I like it better that way. I may want to do something about the jack handle. That's still cheap junk. It's a 2 piece handle that is wobbly when linked together.

I previously had the A frame 6 ton. I need to do something with those pins like you did. Dropped one once and in the basement when one of those goes bouncing off whatever it decides to hit was quite jarring. Those things seem to be like pickup trucks. As soon as people start finding out you have one, everyone wants to "stop by" haha.

Coming together nicely! Impressive work!

I gotta ask..Does the entire pump mount consist of a single bracket with no means of setting belt tension?I went back and looked at Larry's and it looked the same...No secondary attachment or belt tension method..

Yeah. That's how they are on the karts too. They just have a bracket for that one bolt and swing the pump then tighten the bolt at whatever tension they're after.

Errr,Dont like that "one bolt holds the planet" setup!Could a bracket be fabbed up to attach to a few parting flange bolts for a simple jack screw tension adjustment?That would stabilize the single attach so the natural twisting motion would be in check...

I'm sure it could be done. I had the same thought initially, but then figured the karts get away with it. I made the 2nd 1/8" plate today and it seems to at least mostly eliminate the flex, but the 150XL is way tight. The alignment of ports ain't great with the 160. I was running out of daylight if I wanted to be able to cut grass so that's as far as I made it.

What are your thoughts of an idler/tension pulley??Yeah more parts,but look at the belt layout of any modern car!
PS,I think most kart races are short(30-45 min),T2 can be spinning a kart pump waay longer than that!!

It's a good idea, but implementing it may be fun.

On second thought,it would be just one more failure point..

I gave up on the 150XL belt. Tried a hose with the 160 and it wasn't an issue like I thought. I figured it would kink trying to bend as it needed to be, but it seems fine. I cut the shaft on the adapter nut down a bit. The brackets were smoothed out. Need to wait on paint. I ordered 3 160XL belts from McMaster-Carr so they'll be here tomorrow. This one was borrowed from the router test rig. I just got standard XL belts. They have silicone heat resistant belts with kevlar in them, but these are ~$6 each and those are ~$30 each. Hopefully these work fine. In the meantime I'm gonna clean the whole CVT and change the gear oil. Already changed the spark plug. Not saying this will be the final iteration of this idea. I still think I like the idea of a rotor mounted pulley better than the crank mounted pulley. I do like the idea of a turnbuckle style tension adjuster too. If it works OK, I don't know if I'll mess with it or not for sure.

I can't wait to see how this works. Going to be very interesting.
