Mercedes o305 new conversion

Postby menimerc » Tue Jan 24, 2017 10:17 am

Hi everyone!
New here, just started gutting a 1980 o305 old sydney transport bus! I picked it up off a mate for a fair price.
I hope to convert to a nice modern simple motor home. budget and time frame TBA....... hahahaha
Its a very ambitious project and have so manny questions!
I have the manuals if anyone wants them let me know, they are now converted to PDF and easy to share.
A few questions
Has anyone done this bus before? I am having trouble finding some already done 305's..... why?
If there are people out there please send me some advice or things you wish you knew before you started!
If anyone can help me gain privilege to message people that would be great. Reading posts can get you some info, but I wold love to ask more detailed questions to individuals.
Has anyone removed the rear doors from the air compressor system? is this easy? I plan to put my shower where the rear door is.
Advice on second hand windows, sun roof, doors, side mirror etc would be greatly appreciated.
anyway, thought I would start a thred to share my progress and ask specific questions to the Merc o305
watch me on instagram fumble through the process @menithemerc

The problem with most 0305's is they are geared for city life, most will only do 80km's top speed, ok around town but not real good on the hwy but you may be lucky and have a hwy diff in it.
Not sure what state you live in but talk to an engineer before you start as any modifications will need to be signed off by an engineer if you want to register it as a motorhome.
good luck with it, it's a big job but one bite at a time and you'll get through it.

You need to know what you have, you have told us you have a M/B 0305,but mk what 1,2,3,4,5.,when you go to M/B dealer they are going to ask that question,as some parts are interchangeable some are not

A 1980 bus would have to be one of the later Mark II's.

THERE IS THREE MANUALS PRINTED I have all some time it pays to have all different changes make it hard to service or get parts I found most buses in city service are not all the same in parts tourist one have different gearboxes so better to obtain ZF manual with all types

The speed/gearing is not so much of a problem. Higher speed diffs should be readily obtainable, but you will lose some pulling power for take offs and hill climbing. Depending on where you intend travelling, the time advantage may be negligible.

But the other "city" impediment is that it is a low height (not "low floor") chassis, so you don't have a lot of under floor space for storage, etc. A high floor coach chassis gives you space for water tanks, sullage tanks, etc which you will probably need for "environmental" approvals, especially if you intend fitting a shower.

Removal of the centre door should entail little more than capping off the air lines to it, and isolating all the safety interlocks into the braking system.

Ah no, spare parts blokes don't give a . . . . . , All they will want is a chassis number. MK1 through 4 are O305 chassis so that side is all the same.

Now in saying that, don't waste your breath with Mercedes for parts, go through multispares and whites diesels
