Hesitation from 2 gear to 3rd gear

[jelliottoregon]

Hey guys my 60 started hesitating today while driving from the end of 2nd gear to the beginning of 3rd gear. 1st and 4th are fine while driving. I noticed after getting it back from the mechanic there is a pipe from the air intake that goes straight down into the exhaust manifold that isn't all the way connected could that be part of the problem? HELP!
Best regards-

What year?

True 60 series, or the 88-90 62 series with automatic transmission?

Not sure what pipe you're referring to but yeah, sounds like its not a coincidence. Hook it back up.. If it is the warm air intake off of the air cleaner that shouldn't really be an issue. Otherwise there are a lot of pipes there and they all do something.

If it is part of the emissions that will effect the acceleration and so on. Just an FYI, a lot of mechanics don't like working on landcruisers, don't know why, maybe a familiarity factor.

His 60 is an 87 I believe.

John had it Kief. Just a FYI.

[jelliottoregon]

Yes its an 87 and yes it does look like the warm air intake off the air cleaner. Any other ideas?

So for the first time driving longer distances yesterday I had some hesitation problems while accelerating in 2nd and 3rd gear. I spoke to John the land cruiser mechanic I've used in the past and he thought it could be a fuel pump issue or an emissions problem. Today driving around GP no problems at all. What the heck is up with that? Does this make any sense to anyone? I'm tempted to do some longer driving around again tomorrow to see if I can make it do it again. The only other factor is I was pulling a raft and trailer yesterday but can't imagine that would make a difference.

Does anyone recommend a particular shop manual for my 87 60 series? I know Garrett mentioned something a few weeks ago but I forgot. It looks as though everyone is right I need to become familiar with this thing otherwise it could become very expensive to keep running to the mechanic.

Get the factory service manual FSM. worth it's weight in gold!

[Ebag333]

Pulling a trailer can definitely make a difference.

If it doesn't do it without pulling a trailer, but is reproducible while pulling a trailer, then you'll have a better idea of what it could be.

I'd try and replicate it, if you can.

[TOY350]

I still have my FSM from my 60 that you can borrow Jesse.

[jelliottoregon]

Garett,
I've searched for the manual a little on SOR etc but I'm not sure its the exact manual you have. Can you give me the exact title to ensure I buy the correct manual? I appreciate the offer to borrow yours but I have a hard time borrowing things when it's something I really should have myself.
Thanks-

[Kief]

Try wheeler too, ask for the cash discount.. worth a shot. They will have an engine manual and a chassis and body manual.. I think there is even and emissions manual too-not that you want to own it. If you aren't planning on tearing down your rig it may not be necessary to get them, Haynes makes a dang good manual and I often look in those just to get a little more insight on how to do things without all the special SST tools.

[TOY350]

The part numbers from Spectre are:

221-03 Engine, I don't have this
221-46 I have this one, big and thick and expensive. Available to loan
221-45 this one might be overkill

Like Kief said try Wheeler and ask for Steve in parts, he should be able to beat Spectre's prices if you talk to him about it.

I'd love to go for a ride and check it out.

Wouldn't have any time till this weekend though...

Curtis

[2ndGenToyotaFan]

Or keep checking Ebay... I found mine with a 19.95 buy it now price....

[Ebag333]

Is the 60's FSM downloadable for $10 like the 80's?

[jelliottoregon]

The 60 hesitated almost the entire way home tonight:( I guess its off to the mechanic soon. I was hoping it was a fluke episode the other day. John was thinking about trying an electric fuel pump and if thats not it looking at the smog stuff. He suggested it might be better to eliminate smog components and go to an aftermarket carb like a weber instead of chasing smog problems.

[Ebag333]

Sounds like a good plan.

[jmkfj60]

Jesse, If you go with after market carb, let me know how you like it. I have been thinking of having the same thing done to mine. I'm never going to sell mine, and I don't live in a county that requires smog every two years so it would be an option for me. I don't even know if I would be able to pass smog as it is now.

Jesse,

I don't see any mention of where you are with regards to basic scheduled maintenance items such as plugs, cap & rotor, fuel filter, etc.

Any one of those could be causing your issues and should be addressed first.

oh I hope you are not in for a bad day with that rig. lemme ask you if your hesitation is steady state (fuel I hope) or on acceleration and gear changes; reason being I am having a flashback to my '40: bad merge experience on I-84

PO had it since new out of SLC and looked like he changed the oil maybe once and used half sand, half coal dust when he did it the first year of owning it; the oil pump was so worn that the lobes had been ground down to points so that when shifting gears (2-3) the lash that was created in the pump housing got taken up suddenly and the points came together stopping the pump momentarily, in turn stopping the dizzy which shed its fly weights in grand fashion, then stopping the cam and breaking it in two, all at the same time stopping all noise from under the hood. that was my second grenaded dizzy, PO claimed he replaced one before I got it too, so third possibly. Snapped cam was a bitch. good thing I was a 19 year old dumbass with a '55 and F parts motor. Those cams are not exactly the same though.

please excuse my doom and gloom, I'd hate you to go through all that.
what is your history with the '60, what kind of maintenance do you do? how comfortable are you with getting into the guts of the thing?

if you pull the dizzy and put a long standard screwdriver down the hole when the oil is drained you should be able to feel the oil pump working- hopefully smoothly- but if it feels like it has a dead spot from one direction to the other, like maybe 10-15 degrees of rotation you should be looking for a pan gasket and oil pump.

I sure hope it's just a fuel pump daiphram, what does your oil smell like? IIRC if your pump is shot it will dump fuel into the block? maybe there is a weep hole like on a water pump? I forget. A new pump is not expensive, or you ought to be able to get my old one from Rredfj40, It's 'as removed' but worked when I pulled it off a rolled 86 '60 some years ago. ('60 convertable cruising the junkyard)

HTH, and good luck.

[jelliottoregon]

This is a vehicle that has been very well taken care of by a good friend who I bought it from a month ago. All regular work and repairs has been done by the local toyota dealership. I just had a tune up done a few weeks ago. The hesitation is on the acceleration. I plan on having a local land cruiser mechanic do the work as I have little time or experience with this stuff. I hope its something easy.

If it comes down to it would you guys suggest/recommend rebuilding the carb or replacing with a weber or non us carb and removing the smog?

[RredFJ40]

hung out in the 60 section at all? Aisin's are fabulous carbs and a rebuilt one from JimC or Mark Algazy are worth their weight in gold. Aftermarket carbs are a cop out or a compromise at best, just a work around. It may look cheaper early on but the amount of work you'll put into one making it run right just isn't worth it. Then again, you may get lucky.

[knoll0351]

The first real engine mod I did on my Zuk was the weber carb, and then pulled all the smog stuff off. When it worked it was money, but as red stated it was alot of work to keep it "tuned". Conatantly cleaning the float bowl or tracking down vacum leaks around the seals... I'd definately go for his options if it was me. All in all fuel injection is the way to go

spoken like a guy who has kept a '60 together, probably the best one to take your advice from.

I'm a at best after all my years of trial and error, and take my scaremongering with a healthy serving of salt while your at it.

bottom line do what you are most comfortable with, sounds like the truck is in good hands

[jelliottoregon]

I dropped it off tonight. I'm hoping for a fuel pump fix but if it does turn out to be a smog/carb issue I'll post up with the details and ask for more opinions.

I'm no pro. I think I may be blessed more than anything. 255K miles and still going. Planning for a future diesel swap (crossing my fingers that it isn't soon). I wish I knew what I know now before I bought my first cruiser.

[tblume]

amen to that.
