i recently bought a taishan dragon 270 and was wandering what the compression release was used for and how is it suposed to be used. never saw this on one.
Compression releaseon a diesel engine is a starting aid. Activating it by pulling a cable or turning a lever causes one set of valves to open slightly, temporarily disallowing compression. The starter motor then has a much easier time turning the flywheel, saving wear and tear on itself and on the battery. It also turns the oil pump, which then starts pushing oil back into the now-empty passages. My procedure was to open the compression release, engage the starter, then watch the oil pressure gauge. As soon as it was spinning fast enough to indicate pressure on the gauge, I'd let go of the compression release. Except in the coldest of conditions, that was usually enough to start on the first try.i recently bought a taishan dragon 270 and was wandering what the compression release was used for and how is it suposed to be used. never saw this on one.
First thing to do is to make sure the linkage from the operator station to the valve cover is actually connected - on both ends. Then confirm that - when engaged from the operator station - there's actually rotation visible at the point where it goes through the valve cover. If those two things are happening - and you still have no compression release - only then should it be necessary to remove the valve cover. Let me know what you find before actually taking the cover off, and we'll go from there.I have not tried to adjust compression release. I assume one removes valve cover. From there, are there any alingment marks or does one adjust nuts on linkage whatever so valves open just slightly or what?
