Hi All. =20
My wife recently purchased a Wilcox & Gibbs Industrial 5-Thread Serger (515=
-4-52). The handwheel and crankshaft mechanism are completely stuck and on= ly rotate about 1/8" in either direction. I got it to work briefly when we= first set it up by strongly turning the handwheel until it rotated, I put = the belt on the handwheel and it worked fine for the evening. The next mor= ning it had frozen completely and will not turn regardless of how much pres= sure I apply.
Through my investigations, I found that the Differential Feed Shaft and Lev= er are stuck as well.
I opened the machine to the best of my ability apart from removing the oil = pan and opening the main body - I put in new oil, and oiled all sections of= the crankshaft, all ball bearings and bushings that are accessible.
I cleaned the needle/looper section extensively looking for anything blocki= ng these parts and nothing is abnormal.
And after spending about 6 hours trying to get it to work, I put the machin= e back together and turned away IN FAILURE!!!
SOOO - if there is anyone out there that can offer any advice - or point me= in the right direction - I would be eternally grateful.
Thank you in advance!
