Please help! We just got a 1969 Mobil Broom truck and I know nothing about them. This one has a problem with starting. (I think someone hooked up a cut off somewhere). Also I need to replace the broom and don't know how. PLEASE HELP. I'm ready to drive it off a cliff. We also just got 3 old Tymco 600, a Tymco 300 and some sort of flush truck. I will be needing information on these once I find out all the information and what is broke. Any information is helpful. Thank you in advance.

Well robert, is the mobil a gas powered sweeper? if so is it a inline 6 ford?
Do you know what model it is?
If it is a gas/gas M-7 I can help. if not then someone else may take a stab at it.

Sorry Dwan I haven't been able to find any markings on it. I will keep looking for something on it. Sorry, I've just been really busy with building a mobile pressure washing truck and trying to fix our old flush truck.

The trouble will be, is Mobil-Athey went through several ownerships & incarnations. So it'll be impossible to track down any types of manuals, unless you found one in an owner's hands somewhere.

But a starting problem would be an issue for a regular automotive mechanic, me thinks. That wouldn't have anything to do with the sweeper itself. Maybe it has a murphy kill button somewhere?

One type of mechanic that might know about the older mobils, would be agricultural mechanics, who deal with harvesters and field equipment. Harvesters have elevators and such, and the older ones, would be chain drive/mechanical (pre hydraulic) like the old Mobils, I would think.

Thank you

Thanks to both of you. I am trying to get over to it this week. To much work not enough time. I do remeber that I was told that someone bypassed the Murphy Switch at one time. I just wish I knew how to get more hours out of the day.
I'll post here as soon as I find out more information.
Thanks again.

This stupid Mobile Broom

OK I found out that it is a Mobile M-7. Both engines are gas. A 6 & A 4 I think. My brain was'nt working this morning. I also found out that the side brooms are bad, the rear broom needs to be replaced, ( it's a chain driven), and the kill switch is dead. Hopefully I can at least by pass the kill switch to see if the stupid thing even starts. It's been parked outside in a field for awhile. I also wrote down the information off the plate in the cab on the drivers side dash. It has a model number, serial number and both motors serial numbers.

Thanks again,

Any machanic that works on ford motors should be abe get it running within an hour. You will need
fresh battery
fresh gas,
You may also need
battery cables (ground, battery to starter solenoid, solenoid to starter.
12 gage jumper wire about 3 ft long
misc hand tools
and the basic knolage of how a carberated 6 cilinder ford motor works.

Caution working under the hood should only be done if you know what you are doing as serious injury or death may occure!!

Good luck and keep us informed.

I have a M7 and it is a good sweeper but reverse in the automatic transmition seems to be a weak point.

Well, did you get the thing going? Those chain-drive mechanical Mobils were great sweepers! They left nothing in their path :shock: But they were a mechanic's nightmare :twisted:

As soon as hydraulics hit the market in the early 1970s, the chain-drive mechanicals were soon ix-nayed in favor of the hydraulic motors. By the mid-1980s, you could scarcely even find the chain-drive round-nosed anymore. They were great sweepers, for their time.

Still Playing with it

Still trying to get it going. With leaf season and all the rain we just have no time. Hopefully I will get time early enough to have it on the road before spring. Thanks again for the info.

Sorry to everyone that has helped me with this stupid broom. I gave up for awhile on it. Other things took priority. I will try to get back to it soon.
Until then I just had to say thanks. I just bought a 1997 Elgin Whirlwind L that I'm sure I will need some info on.

Thanks again,
