Type2 split and bay Push rod tube, adjustable
fits all type 1 engines 1200 - 1600 ccm
If the crankshaft stroke has changed, the original push rod tubes may no longer adapt in length, in which case use the adjustable tubes shown here.
They adapt by extending them between the crankcase and the cylinder head, then tightening them with nuts to obtain a waterproof result. They are also very suitable as a repair to replace tubes without disassembling the motor or cylinder heads.
Remove the rocker arm axle with the push rods, remove the tubes and mount the adjustable tubes. If you still discover a leak after a while, tighten the nuts and the problem is solved. If necessary, use new seals.
These adjustable tubes are made of blue anodized aluminum, an O-ring seal ensures the sealing between the two parts.
Note : During assembly, check that the push rods move freely and do not touch the inside of the tubes, which may occur with some cylinder heads and/or in combination with a modified valve geometry. If this is the case, you can work slightly the inside of the tubes until the push rods run freely, but check the thickness of the aluminum.
