Need advice putting on a flywheel

[BenF Lurker Find all posts View Profile Close BenF]

Hi, have a 2003 5 speed I'm trying to put on a v6 but the rear end of the crankshaft is too big to fit the flywheel on. Engine is out of a 2003 but had an auto. I took off the driven plate and spacers.

Any chance you can post some pics?

they are an extremely neat fit
you most likely need to run some emery paper around the spigot for the flywheel & inside the flywheel to clean of some off the build up

use the bolts to pull it on tightening them up evenly around

if you have a set of verniers give it a quick measure just to be sure !!

The crankshaft output is too big. It's 52mm whereas the hole in the flywheel is 41.13mm. I have a feeling the crank output has a boss on it for the auto, where I'm trying to fit a manual flywheel. Wanting to know if anyone else has seen this and if there is a removable boss

did the flywheel come with the gearbox?

wasnt there a change in the engine size on the V6 ??

is the crank bolt pattern the same ?

I'm putting a new engine in my car. Flywheel was always on the car. Stud pattern is the same. New engine is same year '03 as car but was out of an auto Prado

Auto and manual box 1GR's in the Prado run the same crank, there's a spacer on the crank for the TC flex plate (on the auto obviously). Can you compare the two engine's cranks or don't you have the original motor any more? It's not out of a Hilux is it? There were a few changes to the crank and flywheel part no's over the years in that model.

Mine is a manual 03 Prado. New engine is from an auto 03 Prado. I believe hilux didn't get 1gr-fe till 05. When you say spacer do you mean like thin steel spacer behind and in front or something more?

I never saw the original crank got the car with engine pulled out already

Have you taken the flex plate off that new engine yet? What does the crank look like behind the plate?

Long story short, this the second engine I've tried, did take the flex plate off other (later model) engine, but not this one yet, as it looked the same with plate still on. I've just found some pics online that I think answer my question, looks like it's just a spacer that makes it look same as later model. Will check in the morning. Will let you know how I go - thanks for help hopefully will be aok
