My contact in Lacrosse has retired so now I'm forced to go through the normal channels & talk with the regular tech support guys. (bummer)
This was the first time I've called up there in over 5 years. Now there is a special toll free number for all of us regular schmucks & a serial number is required for each question.
I'm trying to measure the impeller to diffuser wall clearance with the straight edge which is suppose to be .000 to .005. I have measurements as high as .038 & as low as .014. No matter where you take this reading, its different. (these were also the measurements during disassembly)
My only purpose for calling them was to inquire about this sloppy machine job & find out if this was the norm for these impellers in the extended capacity machines.
I've seen this before, just never this bad. In the past I've adjusted the shims to put the low spots behind the wall & keep the high spots no higher than .005. Obviously, with my differences the way they are, I'm gonna be way negative with the low spots. I haven't checked the depth of the track but rest assure I will know the thickness of the inner impeller wall & the depth of the track going forward monday. Maybe I'm making too much out of this, who knows?.
I guess the most annoying thing about my call was the excessive questions:
Have you talked to the local office about this? (are you kidding me?)
Why were you inclined to tear this machine down?
Are you sure the bearings were bad?
Did the local office participate in the diagnosis? (are you kidding me?)
Then he wants to know what type of thrust bearing clamping system I have. I tell him I have the flat ring that bolts to the bearing bracket. Then he tells me there is a modification for these extended capacity machines. A newly disigned bearing bracket that takes a different type of mounting ring that is suppose to have less chance of distorting the bearing race. I ask if there is a bulletin. He tells me I have to go through the local office. Are you kidding me?!?!?
Of course this modification is costly but it reduces the chances of pre mature bearing failure. I guess my question at this point is: How is this a modification & not a recall??
Either way, if I want to persue the new & improved bearing bracket/clamping system, I have to go through the local office. Like thats gonna happen.
Has anyone heard of this?
I've got other sources I'm checking with & if I find anything worth adding I'll do so.
As far as the sloppy machine job on the impeller goes, I have to conclude that its normal because I wasn't going to get a specific answer. What a P.I.T.A. this whole ordeal was.
Of course I'm sure he took my reluctance to be too specific or answer all of his questions in a completely forthcoming manner as a sign of incompetance.
If all of a sudden I find the local office involved, I will blow a gasket.
