With the priority flow valve installed, no-work pressure tops at 20 bar; still quite a lot of wasted energy, but much better than before.
The next thing I did was swap out the many different flexible tubes that had built up over many years, to a common fitting. I put in steel tube wherever...
After I added the system pressure gauge on my instrument panel, I saw that pressure would go really high when RPM was up. It rose in a linear pattern, clearly a flow restriction. I did some testing to find out where the problem was; disconnecting the lines and running the oil into a bucket...
The hydraulic pump feeds a long steel tube that runs to the rear valve block; I rerouted it to run to a 3 lever valve block near the steering wheel for the front end loader and hedgecutter (and whatever comes later).
First, I made a tubing bender that mounts on my workbench for the heavy...
Engine reassembly is stopped while I wait for the last little gasket.
So here is some of the hydraulic system upgrades I made, which could be of general interest. I did these over some years, but I'll start at the front end.
The European version of the Mercury 85 shipped with a 14cc pump, the...
It was still running smoothly with a blown head gasket on number 2; I don't know how that's even possible.
The tin is looking pretty bad, OH insists I fix that.
A few pictures of the top end rebuild I'm working on right now.
While bringing the tractor into the garage, I saw that the left wheel had a loose bearing; bolts had come loose. I had to take it all apart to clean and repack the steering bearings (taper roller bearings), and I put in proper...
Long time since I posted here...
I've done some work on the old tractor, rerouted and upgraded the hydraulic system, and at the moment reassembling the top of the motor. It had a blown head gasket and the smoke was getting pretty bad.
I'm only waiting for the exhaust flange gasket and I can...
thanks for the recommendation, we'll give it a try.
We just watched "Squid game".
It was ok, but nowhere near meriting the massive hype.
We started with English dub but switched to original language and English subtitles, which is better.
The dubbing misses the intonation, which is important.
I did the same thing; went from 2 single bars to 2 crossed bars, doubling the blades.
My deck is bigger though. 1/2 ton and 9-1/2' wide.
I figured the only reason not to was if there wasn't enough torque available to do the extra work.
The deck maker says 20hp, and my tractor has 85Hp, so...
They held without complaining.
I've only used it that way a few times, but I don't expect any trouble.
The main difficulty is that my FEL doesn't have enough tilt to dump the concrete. I solve that by lifting a little, then tilting the forks back, then the mixer drum forward so I have more...
Lots of things...
My back doesn't like heavy lifting, but my tractor doesn't mind in the least. To pour concrete, I just lift the whole mixer and take to to where I need it.
I added some plates that clamp the mixer to the forks.
4wd 4 ton mobile scaffold;
They seem to be a domestic Portuguese transport company. So no, I haven't tried them.
For this sort of thing I'll use cheapo grips from an area DIY store, ebay Spain, or Amazon.
