before teardown , you need to check the following:
take oil sample of the unit and see what is the oil condition
how many operation hours of the unit (very important)
perform a vibration analisys (very important)
before open the machine will be better make a prediagnostic

regards

You can find the tol in the IOM manual use 19XL teardown book. I go off of oil sample depending on type of load chiller runs at and Carriers wonderful design with no rear motor bearing your low speed is ussally done also. Take it down and put new bearings in regasket it.

holy cow., you already took down the compressor and now you ask for help , manual ?!!?
what am i missing., or shall I say what are you missing?

5 years seems a little early. Maybe just do a front end now but even that may not be necessary. The best thing to do is take an oil sample and see what shows up in the oil. If there is no tin in the oil then chances are your bearings are fine. Leave it sealed unless there is a real reason to mess with it at this point. Once the hours get really up there then you could consider doing it for exploratory reasons.

Here it is.

I believe the factory bearing clearances are listed in the SOM. If you've ever torn down a 19D series low pressure machine, you have a pretty good idea what to expect.

I need to check all bearing thrust and I dont have documentation to find allowable tolerance

You shouldn't need a complete overhaul, was there a bad oil sample or just wanting to check thrust?

HELP

5 years is a decent time to pull the kingsbury thrust and adjust/replace the pads,etc. Not sure you really need to go into the low speeed side of things. Everything will pull out the nose and reassemble back thru the nose. JMHO

Five years was standard on the old low pressure machines, but on the high pressure machines it mostley based on hours. To inspect the bearings and the shafts you have to take the compressor all the way down, so you might as well change the bearings.

5 years seems to be a standard around here. most companies do a 5 year inspections on machines like these. It is not fully torn down, but i kinda agree.

then it must not be a 19, cause my boss told it was, and said i had to take out the high speed. But told me to do my homework on a 19xr.

If you are going to go through all of the trouble to tear down the chiller you might as well plan on rebuilding it. Five years sounds kind of early to be tearing into it. I would go on hours instead of years. If there isn't a large number of starts, and you are not having any problems, I wouldn't tear into it until it had a least seventy thousand hours.

Carrier Chillers

Carrier chilling equipment nomemclature is as follows:

05 Series are open drive recp or screw compressors only
06 Series are Hermetic recp or screw compressors only
16 Series units are Absorption units, water cooled cond.
17 Series units are Open drive centrifugal chillers, water cooled cond.
19 Series units are Hermetic centrifugal chillers, water cooled cond.
23 Series units are large tonnage Screw chillers, water cooled cond.
30 Series units are recp or screw package chillers, air or water cooled
32 Series - electronic controls, motor master, PIC I, II, III.

Hope this will clarify some questions.

Klove is correct........... just with more parts.

The "gearbox" on a 19XR is essentially the same type that is on a York.

I may be wrong but the 19 series doesn’t have a gear box.

The 17 series low pressure had a gear box.

I need some help with a carrier 19xr ( hi pressure)
