Gearbox linkage, clutch line and bleeding the clutch

Some progress with the MR2 🙂 I got parts for the gearbox linkage and I installed most of them, just to test how the stick shifter works and feels. There is some looseness with the shifter base, but I think that will be easily fixed.

Starter motor was easy to install, just two bolts (39 Nm of torque) and that was it. 🙂

After starter motor I installed everything that was missing from the clutch, mostly lines around release cylinder and some other stuff.

I also reworked some parts of the clutch hose and rerouted it. I found out that my original route was not that good if you wanted to do something to it later. The hose is now attached to the original clutch line brackets and is covered with clear vinyl tubing at some corners. (pictures later)

When everything looked good, I was ready to bleed the clutch. Some small leaks, but tightening fixed ’em.

Bleeding was quite easy, but afterwards I found out that while I pressed the pedal it didn’t do anything. Release cylinder just sat there and didn’t move at all. I think it must be the master cylinder, so I need the rebuild pack for it.

I’m still missing (I have no idea where it went) one of the big bolts which attaches the gearbox to the block. A/T and manual have different bolts and the biggest one for the M/T is not available anymore. Part number is 90119-12109 and measures for the bolt are as follows: 12-1.25P x 102-30

Maladar is still sick. Get well soon!

Sick leave from garage

I’ve been sick for at least week, beginning from the gearbox swap. Maladar has been sick even longer, but he tells me every time how vodka helps! 😀

Well, at least there is some progress, I ordered parts to attach the shifter cables and some rubber grommets. If I’m feeling good enough, I’ll go and get the parts from Toyota Tsusho Nordic.

We noticed that the longer drive axle for manual had some damage on in (repairable, but probably an awful job). We measured the A/T drive axle and it was nearly the same length and we decided to use it so we wouldn’t need to fix the correct one. I later checked the lenght difference from the repair shop manual and the A/T drive axle should be about 1cm longer than the manual drive axle.

I’m not sure if that really counts, but we’ll see. The length difference might come from the stubs connecting to gearbox, but I’m not sure.

Edit: Just checked the part numbers, and the part number for longer drive axle excluding the stub is different between M/T and A/T

Clutch piping 2

Clutch pedal felt bit funny, so I opened the master cylinder. Full of something that looked like… shit.

The other cylinder was fine

One of the pipes I did – and some of the pipes I practised with

The other end of the pipe. I tried to pump some brake fluid through the whole system (the beer bottle is there for the brake fluid), but then I found that the master cylinder was full of shit.

The hose is tucked next to gas tank but it is not properly attached yet.

Clutch piping

I bought some Copper-Nickel tube to bend the pipes myself for the clutch. Toyota dealers were not helping this time, the original pipes were not available anymore. I also found the correct pipe fittings for the M12x1 thread and some other parts.

I was mentally prepared for the hardest part, the pipe going under the car. It turned out to be extremely difficult.

Everything went well to the point when I noticed that I had bent the pipe too much and it had collapsed. I got really pissed and left the garage to think the whole thing over again. Next day I got a call from a friend asking about computers, but some reason we soon spoke about the cars. He then wondered why I didn’t get a steel braided line for the clutch and I had to tell him that my local hydraulics shop couldn’t make me a hose with M12x1 ends. He couldnt’t believe me, so I said that I’ll call the hydraulics shop again.

The answer was still “no”. Not possible for M12x1. Rare thread.

Then, suddenly, I found a adapter to change the M12x1 to M10x1, and voil

Lower than your nans tits

I have a small vacation on the lovely island of Malta (and Gozo). I left my AW11 in the garage, just when I got the clutch piping and adapters for it (more about that later). I hope if Maladar has some spare time, so he could squeeze the long clutch pipe under the car.

What caught my eye was this:

rat3

rat2

rat1

My first thought was “Wow, a rat!”

I’ve seen a lot of cool cars on Malta, but this was a total surprise! Roads here are in such condition, that you really can’t drive this low rat here. So, extra points for bravery and you could turn a pot hole into a bump with beetle, if you are not careful. I’ll take my bigger camera with me next time… 🙂

Status upgrade

We haven’t done much during the last week. We’ve been looking for parts to build the clutch line from frunk to the engine compartment. Also missing is the flexible part of the clutch line between chassis and gearbox, but I think I can order one from UK.

Maladar said that we could install a fuel pressure regulator next to fuel filter and I’ve found a possible oil leak near the tubing which cools the engine oil. We’ve also compared the transmission mounts and the top one seems to be different, front and rear one seem to be nearly identical between A/T and M/T. The mounts I got with the M/T are in pretty good shape, so it seems I’m going to use ’em.

Maladar also discovered that one of my drive axles might be damaged, but after going through part numbers, it seems that we can build one good one using parts both from M/T and A/T axles. I need to take some pictures of the axles, I’m not certain if my english vocabulary would do if i tried to describe the problem 🙂

Using A/T axles with M/T isn’t possible. The axles have different axle ends (stubs?) and seems that A/T is bit wider and the axles are therefore shorter. Still, most of the parts between axles are interchangeable.

AW11 as it looked couple of days ago:

Drilling holes for the clutch

The A/T model AW11 doesn’t have holes drilled for the clutch pedal, but for some reason, they’re marked on the metal, if looking from inside. Two smaller holes for attachment and one for piston link.

I’ve already started drilling the holes here, but the markings inside the car can still be seen. Even the mat against metal has holes already for the clutch.

And from the other side:

For the center hole, Maladar did a papercut model so we could drill it from the frunk. We marked the hole area and used a very scientific pliers-method to find the center of the drilling area.

Then some drilling and filing.

Looks weird. There is a clutch pedal 🙂 …and A/T brake pedal. There is no need to change the whole brake pedal assembly, only the pedal part.
