85 supra problems.

[s13kid]

car died. thought it was the fuel pump.

today i had the cap off the distributor and found out that the rotor dosnt turn when the engine cranks.

Im thinking the timing belt went? Just woundering if somthing else would cause this.

crank, alternator ps and ac pullies all spin when its cranking.

[s13kid]

I just got back from removing the top timing belt cover. we cranked it over a few times.

All the pulleys spin. Crank, AC, PS, alternator. but the Timing Belt didnt move an inch which is why the rotor isnt turning on the distributor.

When we went to start it the engine shook a little it seems like the crank and pistons are doing there thing. I thought that the crank turned the timing belt as well but maybe im wrong? or does it sound like its shot.

[DustinsDuster]

the timing belt drives the cams and the distributor, the starter turns the crank and therefore everything else. sounds to me like a broken timing belt. pray you dont have an interferance engine...

[s13kid]

the timing belt seems to be intact and has proper tension... I guess this is what i get trying to daily drive an 85 toyota.

any info from anyone would be a big help. Im some what stumped to what is going on inside the engine right now.

[DustinsDuster]

remove bottom timing belt cover and make sure the belt is undamaged and free of debris.

it is possible the belt broke, and became tangled up in the bottom half of the timing cover where you cant see

[s13kid]

I would love for that to be the case. I'll run down after work and get the belt off.


* there was alot of shit in the timing chain cover... it looked almost like steel wool maybe the belt just kind of tore itself up...

[krustindumm]

Nowhere can I find it specified to be an interferance engine, which generally means it is not. No guarantees though.

Just wondering, is this the one with huge 18" Team Dynamics rims?

[s13kid]

no.


** update **

i found a tooth off of the belt wedged between the idler pulley. I am sure thats what the problem is now. I looked around and it is not a interference engine so there shouldnt be any major damage.

I need to go buy a breaker bar before i can get the crank pulley off so im hoping to have the belt off sunday and i'll go order one and hopfully it'll run again.

Thanks for the help.

[DustinsDuster]

use a large box-end wrench as a breaker bar...

[s13kid]

I was using a 1/2" drive ratchet and the cheater bar im using is to long to fit over the ratchet and under the car. I was going to just crank the engine over to break it loose but i cant do that until i get a nice breaker bar that fits.

unless sombody else has a better idea on holding the pulley still so i can get some force on it?

[krustindumm]

socket that fits the end of the ratchet + an extension for a cheater. idk what your using to hold the crank still though, i usually use an impact on crank pulley bolts.

If you've got nothing to hold the crank still, turn the engine to BDC of the compression stroke on cyl 1. Remove the spark plug and dump in gear lube. Then you can pop it loose. Suck the lube out with a liquid extractor. Before you put the plug in (after your done) crank the engine over with a rag over the plug hole to clear out any left over lube.

[s13kid]

i was just going to let the starter motor do all the work...

[JJ240]

Electric impact if you don't have an air compressor.

[s13kid]

I borrowed a impact but couldnt fit so i tried a swivle and it busted. Breaker bar got it off though. now i've got to borrow a pulley puller and i should be able to have the belt off tomorrow.

[s13kid]

great news... I took a chunk out of the pulley. cant find any remanufactured ones anywhere. Curious to as if this chunk missing will fuck me over or not, i'll post a picture of it later.

[s13kid]

as of now im looking to find one used. I found one vendor that sells a 5m crank pulley/harmonic balancer and its 304$.

here are pictures of the pulley and belt.

[s13kid]

wow there blurry as shit. sorry

[s13kid]

alright i just found a new pulley. Should have the car running next weekend. thanks for all the help

[JJ240]

new pulley works, otherwise take that one to a machine shop and have them rebalance it with the chunk missing.

[DustinsDuster]

how the hell did you break that chunk off?

[s13kid]

pry bar.. the pulley was coming off really slowly so i was like, i'll give it a shot pulling the other direction and it bent a little. then my dad taped it with the pry bar and it poped off.
