Always lube o-ring and seal interior with mineral oil- I use "mechanics" torque on thru-bolts- too loose is bad- too tight, and you can break the bolt- or sometimes strip the threads- but as I remember- 20 Nm comes to mind....just have to have a feel for it-- after about the first 500 I d...

use the thickest o-ring on H-6s-- use an awl to pull out snap rings- My seal puller works on new seals= but is is a factory made tool with a 2 inch twister knob... Even though it's thicker than the OEM? I can't seem find my info, what's the torque spec on the long tie bolts for the case sections? W...

I hardly do enough to warrant something like that.

I installed a new shaft seal and complete compressor rebuild kit on a HR6 in 2014 but it leaked oil every winter. I wasn't sure but the first one was indeed a double lip style and one member stated that he has never had a double lip seal leak! I used the seal protector tool but I guess I'm just luck...

Do you have a recycling capable machine? I did email Mastercool asking what SAE standards the Recoverymate conforms to.

No, we are not both wrong. Recycling is done by a recycling machine. That machine will properly separate the oil and filter the refrigerant. This refrigerant can be reused in anyone's vehicle. Next we have recovery machines. They do not filter or separate oil. The Mastercool filtering system provid...

Thanks for the replies, I would assume that my refrigerant management station would have a built in filter that filters impurities before filling a air con system on a vehicle? Not sure how whatever you are using works but I "assume" that it charges with virgin refrigerant that needs no f...

I do not think Bill has it completely correct. In MVAC, refrigerant CAN be recovered and reused in another owner's vehicle. We are both wrong is seems! https://www.epa.gov/mvac/epa-regulatory-requirements-motor-vehicle-ac-system-servicing I though that I read what I mentioned at the EPA site unless...

I don't think R134A or any other refrigerant gets old. Most wouldn't reuse anything but they do sell inline filters to remove oil, dirt, etc. and it is legal under EPA rules that one can reuse refrigerant if it goes into the same vehicle or any of a fleet under the same owner.

The only possible leak that is somewhat hidden is the shaft seal. In order to see it you must remove the clutch plate and some may have a wiper also which a wad of felt material.
