Fan Clutch Removal - How to get this thing off?

[modustollens]

That's good news - at least the parts are available and not too expensive. I'll see if I can get the old one off somehow.

The vibrations and noise are only really noticeable at idle. Once it spins up fast it is imperceptible. I am afraid that the fan assembly could blow apart and send shrapnel around.

Thanks,

If you roll newspaper and put it in the fan when idling will it decrease the fan rotation speed?
If visco clutch is die fun will stop. If fun will cutting newspaper it means it works properly or it is trigged.

[modustollens]

I would think yes - it seems to be freely floating on the shaft. It will turn either way. So I suspect any resistance placed on the fan will stop or slow its rotation when the engine is running.

BUT! My friend, winter in near!
With bad fun your engine will warming much faster! LOL

[modustollens]

I finally got the thing off! It appears to be a normal part so I definitely missed something. Anyway, the engine runs a little warmer when idling but not appreciably. I drove about 30 km on the highway at 80kph and the temp was normal; though once I turned off-road and stopped it warmed up a bit (obviously the latent heat from the highway); but it soon cooled down once I was moving on the steppe's dirt track.

Anyway, there are still many issues with this old, neglected machine but it gets me to work and back and gives some fun on the weekend. There are a tonne of electrical problems, the inside interior is a mess - like and old farm truck - I doubt the clutch and brake fluids have been changed in 20 years. I still need work on my manual glow relays - I wonder if enough power is going to them - how many amps should the second glow relay draw?

There is some voltage leaks too and I often disconnect the battery overnight. The dashboard had a major short circuit one time and was smoking - no flames though; an electrician rewired it but in such a way that the battery is always on. Not sure if that is worth addressing given how much of a mess the wiring is in. I don't want to spend a lot of money fixing this old thing though labour costs for mechanics here in Semey, Kazakhstan are peanuts - not sure how much they charge per hour of work but I bet it is less than 10 dollars an hour. Wine-maker - do you know the hourly rate or do they even charge by the hour? The labour to pull out the old engine and put in the new one was only 300 dollars. The mechanics here - Russian speakers - used google translate to tell me my machine is "an old bucket of bolts."

I should take it in and get all the fluids replaced. At the least the new engine I put in it runs really well. It starts a little rough when cold (hence I wonder if enough power is going to the busbar) but after 5 minutes it is smooth and after it warms up for 1/2 hour or so it has a good kick. It would be nice to ride in a well-maintained machine just to get a good comparison. Anyway, this machine was the only 4x4 near the budget I had set and it was still higher than what I had originally wanted to spend.

The question now is how cold will it get before it will be too cold to run given that I don't have a place to store it inside and there is no power outlet where I park for a block heater and an intermittent auto-start is out of the question given that all the starting relays must be tripped using manual switches I have wired up into the dash.

The oil in there now is 10w-30; perhaps as it gets colder I should replace that with a lighter oil? I would like to drive all winter but I suspect when it gets below -40 c - and it certainly will get much lower than that - I will be taking a taxi to work and back and have no fun driving on the weekends.

Thanks for the help guys! Once of these days I will make a good video documentary of this old machine which, to be honest, I rescued from the scrap heap!

Hi!

Do you driving without fan at all?

Sorry, can’t help you with second relays amps. Electrical issues is scaring me lol.

I hope, you have a big fire extinguisher or two in the boot after smoke under dash panel.

Why shouldn’t you change your Patrol to another in better condition? Here, in Kazakhstan cars prices doesn’t falls fast from year to year. You can buy this http://kolesa.kz/a/show/12563117 for 18 000$ and after 2 years of not extreme riding sell it for 16 500 - 18 000 $ in good condition.
Many little fixes in your old, with prices 100-200$ in the long run will be much more than costs of maintenance of new one.

Cost per hour counts only in major or official car service stations. In small service stations they take in to account only price for whole works. It is doesn’t matter works will busy 2 hours or 7 hours costs will be the same.

Google translator – connecting people LOL. Next time, say him that your car much better than new Lada Niva. Because Niva, became rust bucket of bolts after 2 years of usual city use.

Manual glow plugs switch is better and faster decision in your case.

I use Liqui Moly 10W40, but our winter not colder than -25. Usually -3 / -10. Your new engine also not so new for using light oil. I think the pressure will be low in working temperature range.

Sorry for my curve English.

Yes - I am driving without the fan. The engine is about one needle width warmer than it was with the fan, only now there is far less vibration and noise.

I'll keep working on the glow relay; though I think I need to understand more how it is supposed to work before I can manually control it. For example, does the first glow relay heat the glow plugs only at the start or does it occasionally heat depending on temperature? I was wondering if my manual secondary relay is making the plugs warm enough. Still, this morning, the glow plug indicator light only flashed for about 3-4 minutes; so, it warmed up pretty quickly.

That patrol you linked to is very nice; but, I can't afford to have that much money tied up in a car - lots of bills to pay back home; indeed, I had to double what I had wanted to spend when I first moved here given that the cars here are very expensive. Plus, I did not want a passenger car - the roads in Semey are like a war zone and I want to be able to get out to the countryside - an escape from the city! So, my options were limited. This old patrol was the cheapest 4x4 that did not look like it would snap in half if I hit one of the many holes in the road here in Semey.

I need to find a good source of used parts for my old machine and slowly fix it up - maybe I can sell it for a good price when I leave here? It is in far better condition than when I bought it, that's for sure.

Today I went to shop and bought a new air filter and I had the fellows at the garage put the machine on the lift and check the differential oil and transmission oil. Plus I had them grease all the grease fittings on the steering mechanism, the grease fitting on the front wheels and on the drive shaft.

I don't need this machine to be pretty or even run perfectly - but it has to be reliable - I don't want to get stuck in the middle of nowhere!

Thanks,

MT

According to manual



First glow relay heating glowing plugs depending of time with 2 second pauses – third draft.
The second relay called – heat holder relay.
Also plugs working only if temperature of cooler less than 75 degree.
So, we can suppose that heating time is not depending from outboard temperature and depend only from temp of cooler.
Mine plugs always works constant time +40 or -20 outboard.

But, I’m not electrician so I can make a mistake.

This GU is just for example and I agree, the price is high. Look around for nice GQ with price around 7 000-8 000$ without major problem. I think it is possible to find one. For example like this http://kolesa.kz/a/show/12564702 actual price will be 8 500$ I suppose.

Roads in whole CIS are similar. For example Federal road in Siberia


and


of course this is the worst case at all, but some of them are somewhere near this.

What is good price?

For example the cheapest Patrol in KZ is http://kolesa.kz/a/show/12501602 but actual price for it will be 5 200$ I think.

There are a few roads like that here in Semey and I have taken great pleasure getting my machine covered in mud. The city roads flood with water with even a slight rain, so it is nice to be high up. The city roads are actually rougher than the country roads though. There are massive holes and rocks and broken pavement everywhere.

That is a good diagram - I looked for it in the English manual and found it - that it not in the 2.8td engine supplement but I found it in one of the other manuals.

I paid less than 5000 for the truck I have now - but it had a major problem, though the replacement engine solved that. I suspect I paid too much and could have haggled the price lower, though I did get it much lower than what he asked This was before I found out about Koleza too, which would have given me more market information. Still, I was trying to stay within my budget; My machine will sell, but for how much? I have already had people asking me about that. Either way, having a machine is better than no machine; and it will cost money for the latter.

Thanks for the help.
