I have a Trav Vac 880 which has been wonderful, but has started to burn quite a bit of oil. I am planning on pulling the engine off and going through it to find the culprit.
First I have to get the impeller off which is where I am having an issue.
The following pictures show the impeller, the impeller mounted to the engine shaft and the hex screw.
I have not been able to get the impeller off the shaft. The hex screw appears to be locking the key into the key seat. Off course I stripped the hex screw. Couple of questions. First how best to remove the damaged flush hex screw (screw extractor)? Second any thoughts on this set up and how to remove the impeller?
I am guessing that the shaft might be tapered, but I am thinking the hex screw needs to be removed first.
I appreciate any thoughts and suggestions. Greg
