Finally got the engine running after all my problems! <img src="/forums/images/graemlins/lol.gif" alt="" /> But I have a few new problems. I didn't set my timing yet or anything, but my truck now idles at about 500RPM.. I'm thinking it's supposed to be a bit higher than that.

Also, my brakes dont work.. I dont' know if there's a common problem with this if a truck has been sitting for a year. I press the pedal down, but there's no pressure at all, unless I pump really fast.

Also, with the brakes, when I do pump them fast, my idle goes even lower than 500RPM, almost stalling the engine.. any insight on this?

And another question... I'll probably figure it out on my own, but none of my driveshafts are hooked up.. but when the engine's running, and the 5-speed in nuetral, the tranny still spins... it doesn't go fast, but it is spinning.. is this normal?

Thanks guys... Once these are figured out, I wont' be asking many questions.. I'll be answering instead! <img src="/forums/images/graemlins/notooth.gif" alt="" />

Pointing towards vacuum so far...

It's normal for the trans to spin like that. Caused by friction from the thick gear oil.

Yup. If it's a carbie you'll want to set it at 700 RPM but if it's an auto you'll need it at 750 RPM, both R and RE



Bad master cylinder, mine did the same thing. Don't drive it.



Yes, this is the vacuum brake booster, which takes vacuum directly from the manifold to boost the brakes, makes it easier to push the pedal, ever driven an older vehicle w/o power brakes? Idle goes down when another vacuum source is introduced into the system, tempoarily causing the engine to run lean(rich?) for a bit, untill the diaphragm fills.....ever seen the size of the vacuum hose that goes to that thing?



I would assume so, prob has to do with not having d-shafts for friction/resistance......



We all learn someplace!! I've learned a TON here <img src="/forums/images/graemlins/kewl.gif" alt="" /> <img src="/forums/images/graemlins/kewl.gif" alt="" />

I agree with everything above.
I just logged on here a couple weeks ago and I'm learning alot I didn't know.

Alright, is there a certain way to point to just the master cyclinder? I dotn' want to start spending money on parts that may or may not fix it.. know what I mean!? <img src="/forums/images/graemlins/smile.gif" alt="" />

Also, how do i set the RPM on a 22RE? Do I have to mess with the timing, or is there a screw that I mess with like on the 22R?

is the fluid level low in the master cylinder reservoir?

set your timing before you set your idle. it is almost directly affected by it. your timing is probably a little retarded.



yes these are symptoms of a bad master cylinder, but they are also symptoms of air in the lines. dont go throwing parts at a truck unless you know for sure whats wrong w/ it.



this is normal, and your truck will do this even when the wheels are on. if youve ever jacked the back of your truck up, turned it on and put it in neutral. youll notice the wheels spinning slowly. theyll spin faster if you slightly push the shifter towards a gear even w/o pressing in the clutch. this is called viscious revolution.

Ok, I'll probably mess with the timing tomorrow afternoon.. so hopefully everything goes good with that.

Thanks again guys.
