Build My Mountain Bike Hauler

Sorry I couldn’t make it man, you didn’t need hearing aides last time you helped me swap an engine!

 

[davegonz]

LOL! I was listening to music on my headphones before Kelly came over. Guess I just left them on.

you need a speaker man,,, those "hearing aides" will let someone like me sneak up and take advantage of your sexy self

Updating this thread with what has gone on this week. The 1FZ is on the way to California. The buyer is 10 miles from where my Troopy came from.

I was finally able to load the engine on the engine stand and started to tear into it. The intake was clean.

 

[davegonz]

Check out the block. No serial number! Replacement engine?

 

[davegonz]

It is an HD. I need to clean the water port.

Clean that sucker out. Thats what it looks like inside. Also replace that fitting.

Muriatic acid wash for the block. Clean all of that cooling jacket. You don’t want that shït in your cooling and HVAC system.

Same press fit as the metal pipe on the other side?

Yessir.

Some updates on the engine. I pulled the con rod bearings, and they all looked good. Cylinder 5 did have a mark on the bearing surface but I was not able to feel anything with my fingernail. The crank was fine, too. That was the worst looking one.

 

[davegonz]

Number 2 bearing in comparison.

 

[davegonz]

The bearing number was #4. The bad part was that I ordered STD Taiho bearings.

 

[davegonz]

So, with a suggestion from John at @Radd Cruisers , I plastigaged the Taiho STD to see how it measured against the #4 stock bearing.

Taiho STD measured to be around 0.002 inches.

The original #4 measured at .0015 inches.

The STD Taiho were on the high end of the standard oil clearance which was probably OK, but I decided to just order some #4.

 

[davegonz]

I cleaned up the motor and degreased all the crud off of it and primered it.

 

[davegonz]

Here it is after painting it with KBS Coatings motor coater.

 

[davegonz]

This is for @OGBeno who gave me s*** about the bypass pipe (scroll up). Man, removing it was a pain in the ass! I ended up using a pilot bearing puller as recommended in another thread.

 

[davegonz]

New bypass water pipe installed.

 

[davegonz]

I also installed a new cam seal, water pump, tensioner, and timing belt. Easy to do with the engine out.

 

[davegonz]

The timing belt cover was cleaned up and repainted with SEM Satin Black paint.
