I’ve so far cleaned the valve block, well the bits I can get at. One of the valve guides was broken and I’ve made a replacement. Well I made two, the first made of stainless steel I orientated the mounting holes 90 degrees wrong! So, the second was made of just ordinary steel as drilling a small hole through the base of the guide a long way in SS wasn’t fun first time around.
Not sure how the original cast guide was broken as it’s buried under a plate that covers the gubbins. The plate is circa 3mm steel that covers it, so nothing could have knocked it. The broken part was still present and trapped beneath the plate which was handy to take dimensions off. The part has a small spigot on the underside.
The orginal broken part is in the left, the new fitted part in the centre, and the billie do 1st attempt on the right!……I’ve just noticed that the part it fitted the wrong way around!
Ive taken out and cleaned all the valve stems, they were dirty indicating that the inside of the block is also dirty and needs a clean.
Getting the stems back in, especially the one with the ball bearing under it was interesting. I eventually used a bit of grease to hold the spring in place whilst I lowered the stem into the hole onto the ball. Im hoping the grease won’t affect anything.
