Popular Post Testament Posted September 16, 2018 Popular Post Share Posted September 16, 2018 pretty common for this to be the case, gearbox gear the same as its much cheaper/easier to design it so you only need to change the small gear. the probably just have more/less tooth contact depending on the number of teeth and it doesnt matter because the load is ngeligible. you want more turns of the speedo end per turn of the gearbox output shaft so if the existing gear is 18 teeth you want one with less teeth/what johnnyfive said the other option is to take the clear plastic cover off and use some twink to change the numbers on the speedo. the correct reading for a landcruiser on the extreme right hand side of the dial is "PERIL" 9 1 Quote Link to comment Share on other sites More sharing options...
Seedy Al Posted September 18, 2018 Share Posted September 18, 2018 Diesel run away. ..... So I had my diesel in my hilux start running away from me this evening while going down a decent hill. I wasn't able to pull off the road till I got to the bottom. However at this point the engine stopped running and I assumed it had demo'd its self. The trail of smoke Dow the Road was epic. A cop also happened to be behind me at the time lol but thankfully he understood when I said the motor is now dead. So once he felt I was very surprised to find it still had some oil in it and it still ran once I primed the fuel system again. First thing I had done while going down the hill was turn the key off to cut the fuel. Was one hell of an experience. Anyway question. Can anyone think why it would manage to stop once on flat land? Its a none turbo. Unfortunately was all caused by blow by I would say. 1 1 Quote Link to comment Share on other sites More sharing options...
M.H. Posted September 18, 2018 Share Posted September 18, 2018 Could oil pool somewhere and run in once on enough of an angle? 1 Quote Link to comment Share on other sites More sharing options...
Yowzer Posted September 18, 2018 Share Posted September 18, 2018 Option A: rings are chooched and pumping plenty of blowby into the intake under deceleration Option B: (if it's one of the versions with a throttle plate, which I'm guessing it isn't) rings are chooched and pulling in oil directly under deccel. Option C: Add a turbo to make use of the extra fuel 1 Quote Link to comment Share on other sites More sharing options...
Yowzer Posted September 18, 2018 Share Posted September 18, 2018 That's pretty weird though, oil pooling in the intake perhaps? Quote Link to comment Share on other sites More sharing options...
Seedy Al Posted September 18, 2018 Share Posted September 18, 2018 Yeah I know why it started running away lol. Bit gutted im now going to be pulling the motor down for a cheeky ring and head over haul. Its a Toyota L. So the 2.2. No throttle plate etc. Had noticed it had been getting a little smokey recently and been making an odd chuffing noise. Im more gutted as I was actually about to chuck it up on here for sale. Ah well.

ajg193 Posted September 18, 2018 Share Posted September 18, 2018 Anyone know how well Bosch LSU 4.9 sensors work in non-automotive environments? Looking to measure the oxygen percentage in an argon environment. @Roman ? Quote Link to comment Share on other sites More sharing options...
Roman Posted September 18, 2018 Author Share Posted September 18, 2018 Not sure but just keep in mind that it can only go from about 8:1 to 22:1 so might not work at the sensitivity you need. And keep in mind it heats the sensor tip to 850 deg which sounds not fun if its potentially explosive Quote Link to comment Share on other sites More sharing options...
Roman Posted September 18, 2018 Author Share Posted September 18, 2018 And you really need gas flowing past the tip to get a good response. If its just in still air it might be unresponsive. Quote Link to comment Share on other sites More sharing options...

And keep in mind it heats the sensor tip to 850 deg which sounds not fun if its potentially explosive A lambda value of 1 (14.7:1 AFR with petrol) is theoretically oxygen content of 0 %. The atmosphere will be argon (inert) and will be venting past the oxygen sensor. The application is a furnace for casting magnesium. The existing oxygen sensor (over 10 years old, custom made) died and a replacement unit would be over $7,000. We're thinking we could replace the setup with a 4.9. 1 1 Quote Link to comment Share on other sites More sharing options...
Roman Posted September 19, 2018 Author Share Posted September 19, 2018 Oh yeah good point about lambda 1. duh. There's a diesel specific version of the 4.9 that I think has smaller inlet holes to the sensor to prevent damage from particles etc, might be a good one to get for that application Quote Link to comment Share on other sites More sharing options...
Testament Posted September 20, 2018 Share Posted September 20, 2018 theyre cheap enough now its almost worth just trying to see how it goes. some things can stuff with the sensor though, like leaded fuel shortens their life probably because some things coat something on the sensor so if theres some other off gasses or particles in the vent line it might not last long. do you know what type of sensor the old expensive one was?

ajg193 Posted September 21, 2018 Share Posted September 21, 2018 We bought an innovate LC2 + 4.9 sensor (had to change the output range using supplied programmer software) and I made up an LCD display using a Nano (convert lambda to %O2) and put it in a nice box. Tested it out using argon from the tig welder and it went straight down to 0.0% O2 (reading 20.9% in free air), so it looks like it will work. Assembled it onto the furnace so it should be ready for testing on Monday assuming the instrument grade argon arrives. Also, don't have sensitive electronics like arduinos near (older?) tig machines when running, it corrupts the memory instantly. If it works that means a saving of about $9k 5 2 Quote Link to comment Share on other sites More sharing options...
SOHC Posted September 23, 2018 Share Posted September 23, 2018 Would anyone in auckland have a bearing puller to get a bearing from a blind hole? I need to pull 2 bearings one has a 40mm ID and the other is about 30mm? Quote Link to comment Share on other sites More sharing options...
kws Posted September 23, 2018 Share Posted September 23, 2018 Could you use grease and a punch to hydraulic it out? Much like you do for pilot/spigot bushing Quote Link to comment Share on other sites More sharing options...
