Ont R Centurion is running

[Mike Cecil]

Centurion oils as per EMEI (Aust) VEH M360 issue 2, November 1973:

Main engine: OMD-110 (O-180) viscosity, cS at 210 deg F= 9.7 to 13.0
Gearbox: OC600 (O-208) viscosity, cS, at 210 degrees F = 29 to 32.
Final drives: OEP-220 (O184) viscosity cS at 210 deg F= 15.6 to 18.0

Oil specs from DEF (Aust) 206A.

From my limited experience, leaving any vehicle for years without turning a track/wheel will allow the upper part of the seals not in the oil to harden and when eventually run, to leak. This Cent was a gate guard for a long time, I seem to recall.

Nice job, Malcolm - congrats, it has come a long way since I saw it.

Tony and Richard, that's some good information on the oils in the Centurion. Thanks. I don't know what oil is in the transmission and final drives as it was changed before I got involved, but the leakage is bad enough it is not likely to be completely fixed by going to a thicker oil so I'm going to bite the bullet and change the seals.

Mike is dead right. This Cent was gate-guarded in the late '70's, we got it in the early '90's, and I left the transmission and final drives that had sat static for at least 40 years as-is. Considering they only need new seals, I got off easily!

Sorry I scooped your premier driving the Centurion. It was just too good a sight to pass up.

There is a Centurion in Hull parked at the Regiment de Hull armoury. As I recall it was at Cote de Neiges armoury in Montreal, and made the road trip at least ten years ago when the then-serving Reg Force WO made some kind of deal. I think he retired and may have left the area.

From conversations, the interior is complete and was preserved, if that is the right word, with a liberal spraying of oil. On hot days the oil would drip out. It might be a candidate for parts swaps.

No problem, Terry.
Thanks for the info on the Hull tank. But actually, our tank is pretty complete in the interior. I suspect our tank was one of the last to be taken out of service so it wasn't gutted for parts.
