Hello all -
Was wondering if I may enlist the assistance of the experts on here with regards to these reports. My expertise in interpreting UOA's is pretty much limited to wear metals and monitoring for any issues.
The reports are from two newly acquired assets with unknown service history - they are a 2005 and 2005 Bombardier BR180 tractor (snow groomer). Both units utilize a 11 gallon hydraulic system and a 16 gallon hydrostatic system. Fluid spec for both systems in both tanks is ATF Type F (Ford ESW M2C33-F) or ATF Type A, suffix A (GM test, DB236.2).
Wear metals appear to be fine but what I cannot interpret are the fluid properties numbers - what is the oxidation, nitration and acid number indicating for a course of action?
We are also trying to verify what fluid is in these tanks ( due to Type F not readily available, I am suspicious there already has been mixing with some other fluid during past services?). Was hoping from these reports to determine what oil may be in there??
Last, any suggestions on this application if we decide to switch out from not so common anymore Type F - the selling dealer insists we use Type F and I say there are better alternatives as long as we do a complete swap over to that fluid (no mixing). I do know the service guide for these machines calls out this spec: Vickers Vane Pump Wear Test 1,000 psi, 176°F/80°C, (ASTM D-2882).
These units will stay outside in temperatures typically from 0° - 32°F, and will be started outside, no tank warmers.
Thank you very much in advance for your help with this!!!
Bernie
