Test Drive Adventure, need advice HR Ambass 36PST
Hi all,
Sorry to come in hot needing help in a hurry but I guess that's this happens sometimes.
We having been working towards the purchase of a 2002 Ambassador 36PST (Cummins 300HP 6BT) for about 3 months
The unit had a leaking head gasket which the dealer finally fixed so I took it about 60 miles down the road to Cummins today to have the engine checked out.
It threw the "code of death" for the injector pump (maxed out at 250 instances in the last 120 hours) but otherwise checked out ok. I plan on requiring the dealer to have this replaced prior to delivery.
BUT.... then this happened.
I thought on the way to Cummins that the unit was struggling on the hills. I don't know the grade but I do know that the level bubble was all the way to the front. The unit lost speed and I ended up with it on the floor. It didn't seem to gear down like I would think it would and then it would surge, miss - something and the warning light would flash once each time. It did this on about every steep hill. Speed would go from 65 approaching to 45 ish at the top (depending on grade / length) - all climbs about a mile say.
Temp was about 200, oil pressure around 60, RPMS about 2000, full boost. A/C was off. RPMs also went down as I climbed.
I tried to downshift using the buttons (Allison 6 speed) but didn't seem to react as I expected so I stopped.
Is this typical behavior? I mean surely the warning light isn't, but is the power where it should be? I know it's hard to say without knowing the grade. I have video if I can post it.
Thanks in advance!
