Canada Day was a blast!
“Head host” Aden and Oscar were there opening 730 at 5:00 pm. We were near Patterson SkyTrain Station. This was the first major event where our younger volunteer hosts would take the reins from Lawrence. We did have a wee bit of a problem with power but it is rare that the wonderful staff of all the Burnaby events let us down! One, Doug, welcomed me back…… before long the organizer Amber showed up with a battery pack, but unfortunately it was dead. No problem Doug saw the problem and had a generator to us by 6:30, long before dark. Aden made the executive decision to have sales because we had no power and up to our hips in people. Good choice, they sold everything. Almost the bus too! (Photo, below: Aden Wong)


Everything went smooth. We had over 4000 guests visit 730. Milan decided to wait until the fireworks started before we tore down…… didn’t want to interject my experience in too much so we did. And now the young ones know why I started load up early, by the time we left the thousands of people that were just enjoying the fireworks were now trying to trample us to get past us
to get on the SkyTrain… ooohhh myyy! I thought that Aden did an outstanding job managing the event!
Feel very sorry for driver Evan!
Years ago when Harry was our driver, he always stayed until the end of the day. He didn’t host and at first I wasn’t sure what he did. Then one day I realized that he was across the street, out of sight taking in what was going on at the bus. So I always kept my eye open to find Harry and he would give me a wink when I did. Well I find myself doing the same now, watching, making sure everyone is ok and there in case the new leaders need some advice.
Sure was nice to not have to stick around until the bus left.

A big “thank you” to: Bryan Larrabee (delivering driver), Evan Russell (return driver) and hosts:
Aden Wong. (Leader), Matthew Walker (who also took photographs), Oscar Kapsa, Sue Walker, Francis He, Ewan Streit, Max Chang and Rod Chew.

And the day marked a successful return to duty of museum bus, TDH4512 (#730). Our mechanical team led by Sean Keating overhauled and resealed the Torus fan. It suffered an oil leak last year. Sean investigated the incident and discovered that somone had ‘bodged’ a fix to a problem of a blocked radiator. We can speculate that BC Transit mechanics looked at the problem and decided that a workaround was cheaper than flushing or recoring the radiator. R They deactivated the radiator shutters, and bypassed a valve to run the fan constantly. It is not unreasonable to assume they did this because the coach was very new to its retirement.
- The Torus is a fluid coupling device that connects the engine to the radiator fan.
- It uses engine oil and a vernatherm valve (a temperature-sensitive valve) to regulate the amount of fluid in the coupling.
- As the engine heats up, the vernatherm valve allows more oil into the Torus, increasing the fan speed to improve cooling.
This system was designed to provide variable fan speed based on engine temperature, improving efficiency and reducing noise compared to a direct-drive fan. Explanation courtesy of Bus Conversions magazine via Co-Pilot.
It was an easy expedient, but had one rather signiciant downside: when the engine was started, until the oil warmed up, rather thick fluid put extreme pressure on the fan seals. These leaked oil, covering the engine hood with engine oil. After years of service, these eventually gave up, allowing oil to pour out of the fan. Thank you, Sean and the mechanics!
