#4 main bearing cap "stuck"

[Wayne G.]

Just finishing up the teardown on a JDM 7mgte. I got to the main bearing
caps to remove the crank and cap #4 (the one with the thrust washer) refused to come loose.
(yes the bolts are out). I don't want to pound it or risk stricking the crank etc.
Whats the best way to disloge this thing. It is almost ready to go to the machine shop.
All wear items will be replaced, oil pump, bearings rings, seals, mhg with studs
etc,
Any tips??

Drop the bolts back in then pull them 3/4 out of the cap squeeze them together and rock the cap back and forth using the bolts as leverage while pulling upwards gently and it should pop off!

1J's method works easily. I did it and the yjust wiggled out. It's a tight fit.

Sweet! That's the same method I have, Ian.
Good to know that I figured that out myself, and you've been building engines for a long time and that's how you do it.

Eric: If they're a loose fit ya have troubles !

Kurt: Yep been doing that way all my engine building life not sure if anyone showed me or like you I just did it that was cos it works!

That worked fine with the other caps but the #4 is blocked in by the counter
weights which will make it hard to get to. Also the the dip stick guide is in the way---

Will try lifting the crank see what happens.

Wayne: Turn the crank a bit

Well since number 4 has the thrust washers, I find a piece of wood and a light hammer, tapping on both ends of the cap lightly helpes to free it. Then use the method mentioned above to finish the job.

Lifting the crank worked great-thanks for the replys
