Pedal to the Metal

Hi guys! Super new here, just arrived home with a 1998 Thomas 30ft Bus.
When driving it home seems like I have to floor it to get it to go. Guess I'm not use to having to really put my foot down to go. Just wanted to make sure this is totally normal. Or if there might some transmission issue going on behind the scenes.

Any info on how buses usually feel and drive let me know. This is the only bus I have ever driven.

Thanks in advance!

Tim

Buses are heavy beasts and can take some power to get them moving.

What engine and trans does your bus have? What speed and rpm did it go to? You may be governed at a low speed or just have a not as powerful package

Thanks for the Reply JJ!

I looked at the paper work. Looks like the Engine is a ER3126B190
And the Trans is a AT545

Not sure what that means.. the bus is flat nose, and 30ft, so sort of smaller side in terms of giant buses... but still a good amount of room.

Whats your thoughts on those?

Also another off question, I want to drive the bus across my front yard into the sideyard.. Do you think it will eat the grass up? Would you put something on top of the grass?

Thatís an older cat 3126

Should have plenty of torque for pulling the bus

Watch out for injector cup leaks on that engine

Just do a google search for 3126 injector cup

This guy has lots of good videos about the 3126 available on his channel

Welcome aboard. I got to floor my bus too. Don't park in soft ground. It will sink.

It takes some effort to move them for sure, especially on the highway. Around town shouldn't feel too bad, I never really go above half throttle until I'm getting on the highway. If yours is geared like mine, you'll never be below half throttle above 55mph or so, it's just spinning too high.

Sounds like a 190hp version of the 3126 engine, is it a MVP rear engine bus?

Thanks everyone for the info! I truly appreciate it. At times, it feels like I bite off more then I can chew with this bus.. Its still parked in the front making all my neighbors grumble.

Yeah the engine is in the front.

I'm going to buy plywood and steak it to the ground. Do you guys think this will help with the sinking or create more problems?

I have a new worry about the turning radius to make it into the sideyard. does the back wheels need to be in place before a turn, or will they follow the front wheels? Not sure that make sense.

I have a 11ft gap to get into the side yard, and require going around a bush to parallel it with the fence.

Any thoughts would be appreciated!! thanks again!

It takes some finesse to learn to drive the bus. I found I could slowly go through the gears at low rpm, but you would only be going 20mph or so. If you need anything near 55+, you just mash it to the floor and let it catch up. There is very little actual motion at the end of the pedal sweep that actually makes you accelerate.

Well I went to move it to the sideyard and it didn't turn over... Noticed their was only one battery, it was at 50%. I am charging it now.. Hope that fixes it. I took it on a 100mile ride home 2 days ago, and it has just been parked ever sense... Any other things to check to get it to start?

Okay I Am in! in the sideyard. I ended up buying 2 new Group 31 Batteries and it started right up! I also pulled over the curb and grass no problem. Fit like a glove. So excited. Let the real conversion begin!!!
