Clifford, I don't know about the turbo having to be removed, but it probably does. I've never had to remove the blower on the 8V, there is about 3-4 inches of clearance but you have to get the cherry picker as tight to the head as possible or you'll hit the lip of the tailgate opening. It does help to remove that silly coolant housing on the front of the engine, that thing will take up every bit of space. Good Luck! | ||

I think that back in the days of Greyhound revenue service, they would roll the whole engine cradle out for almost any maintenance. With the right tools and dolly, it was pretty easy. Perhaps not so poorly designed when you consider that. | ||

Len is correct... Trailways wrench twisters could actually remove and reinstall a power pack in a single shift and have the bus back on the road by he time the next shift came in. My PD4103 had a power pack swap in 1966 and according to the logs and W/O's I have for it, it took two guys 6 hours and 28 minutes from start to finish. The nice thing about being a mechanic back then is you didn't have to fuel the beast up, wash it, mop the interior or wash the windows when you were finished. | ||

by all means, remove the blower, but you may still have a clearance issue with the tailgate. Just be careful. | ||

I have a 4905a in the shop my question after looking at it for a week Not very much time and you can simply remove the engine. With Hound the complete R&R was done in 6-8 hours , with 2 experienced folks and the engine cradle handy. Lots easier to work on where you can get to stuff , and easier to upgrade to things like new hoses with out being double jointed. Being able to see what your doing , priceless! FF | ||

Again, Fred is right... it's so much easier to pull the whole power pack, do the work and push it back in. The time you take to remove the blower and reinstall it is about 20% of the time needed for a whole R&R. Thanks Fred, BTW, why are you in here so late this fine afternoon? | ||

I had a mechanic work on mine and he told it was less time to pull the engine. Eight bolts and a lot of fluids. hardest part was the drive shaft. He used a forklift with a chaine . whole unit came out in about seven hours. Now if you need to get into the top of your engine, there is an opening inside of your coach in the back that will let you get down near the top. Had a started rebuildt and told the mechanic to go that way and said no, he could do it with another machanic and a pipe. He changed his mine in hurry. | ||

You would have to tear the bedroom apart to get to the hatch on this 4905A why people cover the hatches remains a mystery to me good luck | ||

Mike, Trying to remove a head through the access hole is a real PITA. I tried it twice, and just pulling the power pack was a whole lot less work. For me, pulling the head from the back isn't that difficult, but trying to explain how I do it is difficult in this flat forum. I am not articulate enough to explain what I mean in the proper terms. I would advise anyone that is doing heavy work to a transverse mount bus engine to just pull the power pack. Pulling the drive shaft isn't hard, just remove it from the spline as you go. | ||

Fred is probably taking a break from excercising those new S50 horses......got to break them in gently you know I Wish, there is a long way between "running" and usefull in a bus. Things like air lines , new power steering lines , water to the heaters/defroster . Batteries , start + house , a trace to run the air cond , and all the rest. Happily we did purchase a boat that can be towed by the VL. AS most know the Sportscar 4106 has limited tongue weight ability , so 6000 lb tows is a no,no. http://www.yachtworld.com/core/listing/pl_boat_detail.jsp?&units=Feet&id=2020355&lang=en&s lim=broker&&hosturl=northeastyachtsales&&ywo=northeastyachtsales& This is short enough to keep the total bus + trailer length under 65 ft , the state requirement in lots of states. For a diesel guy 3500rpm cruise is new , but Im told the 305 Chebby is fine with it. FF |
