A new PD4107 Owner

Shagger · August 18, 2013, 11:46:17 PM

Hi everyone,
I have just brought myself a GM PD4017 #1027. It has been sitting in a shed for the last 18 years. It was started 8 years ago by the sons, after the owner passed away. They started it and said that it fired up straight away. When I tried to start it, it would turn over so I put it a float and got it up to my shed. There was still air in the tyres and we put air in thru one of the valves and the airbags loaded up and we managed to tow it out of the shed and the brakes worked too.
I have since found a detriot guru (40 years living and breathing Detriots) who pulled the engine out and we found that 2 of the pistons had corroded onto the liners. He believes that moisture some how got into the exhaust, and with condensation and evaporation over the years worked its way up and into the 2 pistons with their exhaust valves open. Anyway I am on my way to rebuilding the engine so I can drive it at least.
Everything in the engine bay is original. there are only a couple of screw on filters.
I am open for ideas about anything but I would like to know if anyone has changed the exhaust muffler and how they got it out. It looks like I have to take a panel out to the engine bay to get it out and if anyone knows where to get another muffler from or if there is a better / quieter one available.
I also have a broken top manifold
Once I have it running I will be looking at upgrading bits and pieces of it and will be looking for advice from any experiences along the way.
I will get some photos up once I get into this and get it back together
Thanks

Welcome shagger! This is a great group, lots of experience here! You should start by editing your signature and give us you location and basic information on your bus, look at mine as an example. Is the bus converted? Good luck to you! You are lucky to have the bus inside to work on it!

They had an optional muffler mounting by the fan on rear side between fan and radiator. Some have commented that a hole in the top of the inboard muffler could cause a fire in some situations. I believe it was designed to be removed in a pit. Had a hanger from top to support it. Changing to the opt one will require different pipes also. Luke probably can get/ carries what is needed.

Congrats! I am also a new owner of a 4107-1118. Where are you located? I'm in Southern California. It's nice to keep in touch with other new baby buffalo owners.

There was still air in the tyres

I'd guess north of the USA border. Or, across the pond?

I believe he's from the land down under.

Welcome, Shagger, to the joys of GM bus ownership. Nice to have another member of the V-drive club.

Welcome. Can't help you with mechanical inquiry but congratulate you on the acquisition.

Bob wins the door prize of one expired transfer for getting Shagger's location correct!

PD4107-1027 was delivered new as fleet number 705 in June of 1967 to Ansett Pioneer, HQ'd in Melbourne. This is one of a 15-bus order placed thru GMOO-Australia. (GMOO = General Motors Overseas Operations)

Yup, it's a RH drive coach! Here's a pic of it's sister, PD4107-1031, fleet #709:

"Or, across the pond?"

Australia is across a pond!! Just way, way south and not the one going east.

Look at his email it was ".au" that would be Australia.

Gaday Mate, welcome to the board enjoy your ride and ask questions where needed.

No argument here. Just trying some humor? Sorry.

Shagger · September 19, 2013, 12:55:32 PM

Wow,

Thanks guys for all of your replies. Yes I live in Australia, On the Gold Coast which is similar to your Miami as far as it is the tourist mecca of OZ.
I have just last week end had the motor running ( still out of the bus) and over the next few weeks I will be painting the motor and cleaning the engine bay up before I put the motor back in and then it should run.
chessie4905: I think you are right about muffler coming out thru from underneath and I would be interested in looking at the optional exhaust mounting. I am not sure who "Luke" is
RJ: Thanks for the photo, Thats what she look like except the windows have been changed to having sliders at the top to let some air in.
How do I change my Signature, add a photo and give basic info on the bus? I would like to add things on. I tried to add a photo once before but the photo was too big.
Yup new guy syndrome.

The same colours as it was when they first came over
