Electrical trouble shooting
Unfortunately, we don’t have much to report since we are still trouble shooting. We did figure out that while we see many advantages of having a pusher bus, one major disadvantage is that a pusher has extremely difficult engine access. Still, even though we didn’t expect the starter to be the issue, we decided to take it off just to rule it out.
In order to fit between the cooling fan and the engine, we first had to remove one of the fan supports. The only way to do that was by cutting part of the support spindle and push the rod out. We unbolted the bump plate from underneath the engine once the rod was removed. This is a thick steel plate that prevents the engine from getting hit when the bus drives over a big rock, or highway hazard. Clearly that had happened before because three of the bolts that hold the bump plate in place were completely flattened.
Dismantling problems
With those two items removed (this was a two-day process) we gained enough space to be able to disconnect the hot and neutral wires from the starter. That said, since I am right-handed and can I only can fit my left hand in the area we need to reach, so it took several hours to get it done. Then it was time to get underneath and remove the two bolts that hold the starter onto the engine.
Having the bus in a storage space with a gravel and dirt lot slows down the process. Between the wind and other vehicles driving through the lot, dust in the eyes in an issue. Safety glasses do not help and goggles won’t work with the limited space we are working in plus we are dealing with the excessive outside temperature. So in short; are we having fun? No, most certainly we are not. That said, if we get the bus running before we hit the 20 year mark the satisfaction would be tremendous!!
Never give up
Laying on the gravel and dust to remove the bottom bolt from the starter was easy. Fairly decent access and space to move the ratchet. Getting to the top bolt, which is hidden into an inaccessible space above the starter, was a whole different challenge. Eventually we managed to get it off. We used a ratchet with a 3ft extension and loosened the bolt while standing behind the bus and ratcheting inside the engine compartment. It is amazing that getting a bolt loose of a bus part that has no issue, still feels like a victory. How deep we have sunk…
Once the starter bolts were loose, we had to get back under the bus and slide the starter over hydraulic and fuel lines all the way aft. From there we could maneuver it between engine and aft hatch to pull it out. On the bright side: the teeth on the flywheel look excellent end we didn’t see any rust.
The only thing we did notice to be wrong is that the little starter wire clearly had a break in the connection because it did not have to be unscrewed but pulled right off. Could this really be the cause of the problems? We doubt it, but it would be great if it was. And as mentioned earlier, it would not be the first time that a simple connection break is the reason of a skoolie no-start.
Now that the starter is off…
We took the starter home and put it on the work bench for a test start. It runs with light noise, but not sufficient to be an issue. Some of the teeth are slightly warn and so is the core. But all in all it is not a bad starter for the amount of mileage that is on this bus. So we will clean it up some more and then put it back.
We also still have to replace the boost pressure sensor. Problem is that we simply cannot reach it. I am afraid we actually have to cut the bench inside the bus to get access to the top of the engine where this sensor is located. That is a problem for later this week after we put back the starter…
