tk sltci throttle valve

[froggy]

does any body no what suction pressure an sltci throttle valve should be as i have seized compressor for the second time im new to tk have only worked on carrrier units which use cpr valves which dont seem to cause to many probs

[cadwaladr]

flush that system why did the first compressor fail? and how long was it before the second one failed.

[charlie patt]

both evaps running max 34psi best to check just after df is the receiver glass dirty as cad suggests? how much oil is left in comp? also check it has a mop tev as they had a mod but if throttle valve ok it cope is it mainly on frezzer work

[gravy258]

all set at 28psi for R404a

[froggy]

the compressor snapped the crank oil was clean and full and is only running chilled +2 on compartment 1

[Robert Hilton]

Was it a rebuilt comp? Were OEM parts used or imi?
Was the flywheel house removed at some point?

[charlie patt]

what happened to old comp boke up?

[froggy]

compressor was a reman no signs of houseing being removed

[gravy258]

was it a LS compressor? and does the compressor still turn, or has it seized then the engine has snapped the crank?
Or is it a alignment problem with the drive coupling or compressor to engine?

[froggy]

yes it was a large shaft comp not seized snapped at the balance point also had rubber clutch bushes missing if throttle valve u/s would snap a crank ?

[charlie patt]

possible after df or on freezer work but they are pretty durable comps

[gravy258]

nah slugging wouldn't snap the crank, thermo king can handle that OK,
a misaligned pulley/clutch or alignment of compressor to bellhousing would.
If the throttling valve was letting in say 100psi, the engine would overload
