A couple of notes to add that might help someone.
1. Score a line on the hose (the metal part the banjo bolt goes thru) and the reservoir body so you know how to orient the hose when reinstalling.
2. Igofar's ATF-acetone penetrating fluid has merit. If you don't trust him, here's extra "proof."
"Machinist’s Workshop Mag™ recently published some information on various penetrating oils that I found
very interesting. Some of you might appreciate this. The magazine reports they tested penetrates for
break out torque on rusted nuts.
They are below, as forwarded by an ex-student and professional machinist. They arranged a subjective
test of all the popular penetrates with the control being the torque required to remove the nut from a
“scientifically rusted” environment.
Penetrating oil .......... Average load
None ........................ 516 pounds
WD-40 ....................... 238 pounds
PB Blaster .................. 214 pounds
Liquid Wrench ............... 127 pounds
Kano Kroil .................. 106 pounds
ATF-Acetone mix ....... 53 pounds
The ATF-Acetone mix was a “home brew” mix of 50 - 50 automatic transmission fluid and acetone. Note
the “home brew” was better than any commercial product in this one particular test.
Our local machinist group mixed up a batch and we all now use it with equally good results.
Note also that “Liquid Wrench” is almost as good as “Kroil” for about 20% of the price.
Steve from Godwin-Singer says that ATF-Acetone mix is the best and you can also use ATF- lacquer
thinner 50 - 50 mix."
3. As well, I was careful when removing the adjuster knob to not lose the ball bearing or spring. However, when trying to reassemble it the ball bearing shot like a bb out of a gun into the world of the lost. After saying a bad word once I figured; well, do I have any ball bearings here, to which I had a brainstorm. I went over to the bench and dug out a couple of old bearings and popped the smallest open. The ball bearing worked but was a bit small. I opened a second larger bearing and voila, worked like a charm and no visit to the hardware store. I aslo have another 5 or so spares if I lose it the next time I R&R the preload.
