Toyota Coaster Motorhome Conversion – Floor Installation and Wheelchair Lift Dismantle

There are some days that are just disappointing and our last day on our Toyota Coaster had us walking away with a frown. Not today, today would be great. We just knew it. Our goal was to dismantle our wheelchair lift and replace our damaged sub-floor.

The wheelchair access in our Toyota Coaster was at the rear of our bus, and opens like a ”clam shell’. It is not a standard lift however, and when discussing with people who install the wheel chair ramps, they stated it looked like it actually came off a Ford van or similar, and was made to fit the Coaster. 

As it was made to fit, it has been completely welded to the chassis. Of course we would pick one with something non-standard and difficult to remove. Either way, we decided to still give it a go, and remove what we could. 

Dismantling the wheelchair lift – 

The easiest place to start was the hand rail, and fold out ramp. These were held in place by a few bolts and were easily removed. 

This now just left the main lift. There was a steel plate on the main lift area, and underneath it ran all of the electrics. The electrics looked like they were connecting each bit of the lift, and needed to be disconnected for us to be able to remove the pieces. So it made sense that we had to start by removing the steel plate.

A lot of the small screws in the steel plate were threaded so it took a fair amount of effort and frustration to try and undo them. Two of the screws were unable to be taken out and a grinder was required to cut the heads off. 

After all of the screws were removed, we were able to remove the steel plate. This allowed us to access the electrics underneath. 

We were right. The wires ran under the metal plate and linked everything together. 

After reviewing the wires (and much to my disagreement!) Shane decided to cut the wires leading to the first piece of wheelchair lift he detached.

‘Check it’ he says. Of course I was not surprised to find it no longer worked. Shane had broken the electrical circuit and now we were stuck with the wheelchair lift down. This became priority number one now as without the electrics, there was no manual way that we were aware of to be able to close it again.

To fix this, Shane got some female insulated electrical blade terminals and a switch. He stripped the wires back, crimped the terminals on and connected them to the switch. 

For anyone out there like me who doesn’t understand that, he basically fixed the broken circuit by adding a new end and reattaching it to where he had cut it off from before. Kind of like cutting a circle, taking part of it away, and reattaching the ends to make a smaller circle.

So now the pieces of the lift had all been disconnected, and the electrical circuit was fixed, we were only left with the ‘clam shell’ doors. 

Replacing the Sub-Floor – 

If you haven’t read the previous post to this one, Shane and I had some damaged sub-floor at the rear of our Toyota Coaster motorhome. Water had leaked in via some damaged seals, and the back 30cm needed replacing. 

If you want to see how we removed the damaged sub-floor, you can read about it here. 

It was now time to replace the floor with some new wood. 

The original sub-floor we removed was 15mm thick. We wanted to replace this with marine plywood in case there were any future leaks. Unfortunately, we were unable to find 15mm marine ply to replace it. We decided to buy 6mm and 9mm marine ply which we would glue together to make the 15mm.

So how did we do it?

• Start by measuring the wood, and mark it up with a dark sharpie (or similar). 
• Use some clamps, and secure the wood to a solid and stable spot ready for cutting. 
• Use a jigsaw to cut along your marked lines. 
• Make sure the wood fits into position, and adjust and cut as necessary. 
• Once the wood is ready, remove it from position and spray the metal floor of the bus with some sort of Rustguard and allow to dry. 
• Apply a layer of liquid nails to the metal of the floor, ready for the new wood to sit on top. 
• Lay down the first layer of wood, and then apply more liquid nails in between the layers, and place the second layer of wood into position. 
• Place something heavy on top, and allow to sit until set. 

The sun was setting and it was time to reflect on the day we had had. The day started well. Then after multiple trips to the shops and the issues with the electrics we were feeling quite certain it was going to be another day of disappointment.

But it wasn’t!

We fixed the wheelchair lift and removed what we could. We cut all the wood, and replaced the sub-floor. It was a day of teamwork with our wheelchair lift and sub-floor, and we got there.

It all went well, except our sunburn… that was another story!
