Faunsdale, AL | Couple of pointers...........
If you are working with one that has been converted to ISO barrels, the operating levers will be pinned onto the small vertical shaft that runs up through each barrel. Drive out the small roll pin that holds the lever on and then you can drive the soft plugs out the top of the SCV by tapping on the bottom of the shaft where the lever was removed. Many times the leak is only on that shaft with it's two tiny o-rings and backup rings and you can replace them from an o-ring kit. The soft plugs will go right back into place and seal just fine with a smart tap with a hammer in the center.
If you are only working on the barrels, you can avoid removing the cover with the flow control lever through it on those converted SCV's by taking the lever off the flow control shaft. It is held on by a tiny roll pin. Do not turn the shaft before putting the lever back on as it is possible to get the lever on backwards and mess up the flow control function. Fast will not be fast etc. Once that lever is removed, the operation shaft will come up through the top where the soft plug was. If working on original style with welded steel operating lever/shaft, it must come out the bottom anyway, so you can easily get the E clip off the top of the shaft without removing the cover with the flow control shaft through it.
On converted units, the snaprings retaining the barrels in the housing at the back are sometimes hard to remove. Two screwdrivers or a screwdriver and a sturdy pocket knife will get them out. Take a screwdriver and wedge between the barrel/collar and the snapring and prevent it from twisting in the housing while you pry the opposite end out of the groove. Many times, the whole ring just spins in the groove as you pry up on the ends with a single screwdriver. | |
