As it seems like you will be devistated when your precious 7115 is done I'm going to buy that pepsi can and then place it into a delicate collection and maybe draw 'Scraps of 7115' on it LOL 1 Link to comment Share on other sites More sharing options...

It's parked behind 7294 on the dead track in RTC. Right next to the three BAE Novas that are being commissioned... I'd be surprised if a single C40LF lasts into 2019. Those are in the absolute worst condition out of all buses from what I can see. 1 Link to comment Share on other sites More sharing options...

GORDOOM Posted November 4, 2018 Report Share Posted November 4, 2018 Will the older engine affect the longevity of the ‘99s? Or will there also be Orion V Suburbans hanging around that will make them less oddball within the fleet? 1 Link to comment Share on other sites More sharing options...

That is why many agencies are rapidly retiring their Series 50 coaches. They're old. The age issue is an additional reason why they're on the way out. It wasn't a good engine, even when new. As for S50Gs; down here in LA both LAMTA and Foothill Transit still have coaches operating with this engine. Link to comment Share on other sites More sharing options...

It wasn't a good engine, even when new. Don’t know where you sourced yours, but the 200 odd diesel versions that my property had before the EGR change came about were excellent engines, sharing the legendary reliability of the 60 series. There’s a reason they were so common in trucking. The only thing so stay on top of was the main part that made them different from the 60s...being a 4 cylinder, there’s a gear driven counterbalance assembly to cancel out the inherent vibrations 4 cylinders produce. Bearings can spin out of them, triggering low oil pressure shutdowns. Won’t take out the engine, but will require a tow. Comes out as a complete subassembly once the oil pan is off. ^This thing. 1 Link to comment Share on other sites More sharing options...

The counterbalance shaft is the primary target of my comments. Many agencies had difficulty with them. The late busdude.com used to comment on how Pierce Transit was having them fail at high rates; Detroit warrantied them for x miles after a rebuild and they would rarely make it that far. PT was tracking the failures closely, and would regularly send in warranty claims. The charter company I worked at did a bunch of S50 repowers in the mid-00s on their two-stroke fleet. As you note, some of the EGR versions, which I had the pleasure of driving extensively, had issues, especially with power. And we did lots of counterbalance assembly (or off-set balance shaft) swap outs in our shop. We'd occasionally get a failure a long ways from home, stranding the bus/group until we could get a replacement bus out there. 1 Link to comment Share on other sites More sharing options...
Bus_Medic Posted November 5, 2018 Report Share Posted November 5, 2018 Admittedly, stranding 47 passengers overnight in a remote location isn’t something we had to deal with. The TTC sourced their remans directly from Detroit Diesel, never had any real longevity issues with them, but it would need to be replaced at least once during the life of the engine...which for us, is about 5 years, or 250 000/300 000 km (give or take) As I recall, there was never a hard prescribed service life. We dealt with such volumes of parts that warranty claims were assigned to a couple of dedicated guys in our central shop downtown, out of sight for the most part. We’d just tag them and they’d leave on a skid. Through experience, we deduced that when it started throwing multiple codes for low oil pressure, that was where you looked first. 1 Link to comment Share on other sites More sharing options...

I never heard the bus go by unless it was a Series 50. In that case, my room vibrated. If anything else was assigned, I might as well have not been on a bus route.

Aren't the C40LFs being swapped though? Pretty sure all the old C40HFs were. Also I just keep forgetting about NABI... Link to comment Share on other sites More sharing options...
