PamPoovey Posted January 27, 2015 Share Posted January 27, 2015 Has anyone ever rebuilt one? If so, what would be the steps, what do I need to look for if it's not warped or anything? Also, I was looking at RockAuto for parts and it was suggesting a fan clutch wrench. Is that absolutely necessary? I will be doing the work myself and just want to make sure that I have all the necessary equipment before I leave myself stranded. I will be replacing all the belts at this time, including the timing belt and water pump. Any advice is greatly appreciated! On that note, I also saw a speciality tool for the pulley, is that also a good tool to have on hand? Thank you in advance for your help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

k9sar Posted January 27, 2015 Share Posted January 27, 2015 never replaced mine. I shot it full of silicone cause it was noisy as hell. Let us know how you make out. We're here to help Link to comment Share on other sites More sharing options...
PamPoovey Posted January 27, 2015 Author Share Posted January 27, 2015 (edited) It's so lovely having all of you blokes as my cheerleaders! It has been noisey for over a year, about a week ago, it began making it sound like my truck was reving at higher RPMs, and after two days, it returned to being noisey and hasn't been that higher sound since.

stabworthy Posted January 27, 2015 Share Posted January 27, 2015 I have pinned many fan clutchs in my life. Mine is ... "stuck in the on position" for like 6 years, it's whatever. Buuuuttt I never used no fan clutch wench , 10 mm and breaker oil. But if you are getting to the timing workings , you will need a pulley puller and it's helps to have a chain wrench and 1/2 breaker bar. Link to comment Share on other sites More sharing options...
Precise1 Posted January 27, 2015 Share Posted January 27, 2015 LC-9 in the FSM basically doesn't say anything about rebuilding it and doesn't even have an exploded view so... I think I see how to disassemble it, but have never considered trying to rebuild one. If it has play or feels crunchy, the shaft might be scored, but other than that it is 'take it apart and find out' in my book. Ok, because I was curious... by a mechanic with a Nissan part. (With the runway at St Martin and a gratuitous turtle) https://www.youtube.com/watch?v=LpzJsav3rsw And... https://www.youtube.com/watch?v=N_GkuTgJr3w I'd say you are SOL, but... Hurah, hurah, sis-boom-bah! Take it apart! Take it apart! Yay! B 1 Link to comment Share on other sites More sharing options...
5523Pathfinder Posted January 27, 2015 Share Posted January 27, 2015 (edited) Never rebuilt one, not even sure they can be! As far as replacing it, no wrench is needed. Remove the small lower piece of the fan shroud, unbolt the rest of the shroud and remove. Then you can remove the 4 10mm nuts holding the fan clutch onto the water pump. The drive belt can be left on to assist in holding the pulley(you may have to use a flahead screwdriver to hold the other nuts/studs).

k9sar Posted January 27, 2015 Share Posted January 27, 2015 mine sounds like it's full of gravel again but it's too damn cold to do anything about it. Don't think I have to worry about overheating due to a failed clutch. Link to comment Share on other sites More sharing options...
adamzan Posted January 28, 2015 Share Posted January 28, 2015 Last winter mine seized on and was making my heat, well not so hot. I drove without it or any fan for over a week and the temp stayed the same. Then again it was -20. Link to comment Share on other sites More sharing options...
PamPoovey Posted January 29, 2015 Author Share Posted January 29, 2015 Thank you all for allllllllllllll your help and putting in the time and effort to find me the videoes! I am soooo grateful for the advice on what tools to buy and what socket size I'll need. There is play with the fan, it does still function. I tried to get silicone spray in there, but sucked with the betls in the way and it being 6º, I wasn't going to work on my truck just yet (since I only have the street to use as my work area due to living in an apartment). Thank you again!!!!!!!!!!!!!!!!!!! Link to comment Share on other sites More sharing options...
Kingman Posted January 29, 2015 Share Posted January 29, 2015 Make sure the pulley doesn't have play in it when you're wiggling the fan as well. If so the water pump is toast. Just sayin'. 1 Link to comment Share on other sites More sharing options...
PamPoovey Posted January 29, 2015 Author Share Posted January 29, 2015 Precise 1, I agree, I am SOL.....Thank you for that. I ordered today... Stabworthy or one of you other kind gents, can you tell me what I will need the chain wrench for. Link to comment Share on other sites More sharing options...
Precise1 Posted January 30, 2015 Share Posted January 30, 2015 You are welcome, but sorry, yes, that is what I have always done; just buy another one... To hold things still while you loosen the bolts, but unless they are rusted in place, this shouldn't be necessary. They are only 10 and 12mm nuts and bolts and you can hold onto the fan somewhat to keep things from rotating if you don't take it completely off first.

k9sar Posted January 30, 2015 Share Posted January 30, 2015 I use a long thin screwdriver wedged between the fan shaft and one of the other bolts. Crack each loose while you have something to brace then it's easy to remove without holding it tight. Another way is to use water pump belt itself. Either clamp 2 sides of it together or tie a rope around sides and twist until the belt is WAY too tight on the pulley. That will use the engine to hold things in place while you remove those pesky little bolts. and a ratcheting box wrench works great 1 Link to comment Share on other sites More sharing options...
