All season excavator hydraulic oil 👍 cheap because you buy it in huge quantities and need only half a litre for a motorcycle oil change, works great even in sub zero temperature riding, change it frequently and it's the right stuff. Great for 2-stoke transmissions and Montesa Cota 4RT transmission which is separate from the engine oil.

Teteer-totters or anything that moves makes for a dangerous demonstration, same with wood. Concrete patio stones with holes drilled in them and lag bolts into inexpensive landscape timbers is perfect. You build ladder like structures and bolt them together like natural rock formations. Sprayed on concrete over wire mesh forms would be even better. Build your whole section to assemble onto a tilt box trailer and you have an impressive mobile trials section that every class can ride.

Threaded rod, large socket, couple of nuts 👍 so easy, the sleeve part is cut out of a spent CO2 canister like they use in paint ball or pellet guns. Use the same tool to insert the new bearings, no hammer and no heat is required because you can pull the bearing straight in or out.

On the mono bloc 4 pot clippers that have no cotter pin or bolt holding the pads in place, the pistons on outside are prone to seize. Watch for wear on only one of the two pads if your brake is weak. I literally forced the working pad to stay retracted and by applying hydraulic pressure at the lever the seized side popped free. Corrosion on the inside of the 2 aluminum threaded plugs is suspect and I've only seen that problem on that one specific model calliper. I think it was 2017 they used that brake model extensively.

First the rod will be too short by the diameter of the ballbearing that was suppose to be in there and second; the ballbearing is in there to isolate the spinning parts from the non-spinning part (the actuator rod) so if you left the bearing out, first hint would be not enough adjustment and if you worked past that issue, the next problem will be the rod will want to spin when pressure is applied to the actuator. If the ball bearing doesn't fall out using gravity try a magnet.

Cleaning and lubricating Plain roller chain Remove and place the chain inside a large (4 litre) disposable plastic oil jug. Add kerosene or your favourite cleaning fluid. Close the container, agitate and then drain off the dirty solvent, repeat process if necessary until the chain is clean inside and out. Now pour thick gear oil into the oil container along with your chain. (inexpensive chainsaw bar oil works dandy and is available in a variety of weights) Shake and then leave it set until lubricant has completely penetrated into the rollers and pins of the chain. Hang the chain on a hook over a catch pan until all the excess oil has run off, wipe the chain lightly and re-install on your bike. Ride motorcycle vigorously and repeat Unsure how much your chain is bagged out, then lay or hang it next to a length of new chain, if it's stretched out by one link over the length of ~100 link chain then your chain is stretched by 1% and on the way to needing replacement soon if you want your sprockets to last.

I don't even need to read the thread to know that if a 4RT gets hard to start or outright fails for no obvious reason, it needs a valve adjustment. Not a check or inspection, but a very careful and accurate reset of the valve clearances.

CMA is nothing more than an event insurance broker that periodically records the event results that somebody else built and participated in. If that's all you ever expect from them then you won't be disappointed.
