Fan Bracket Bearings

[PJCB]

I did my timing belt, water pump, thermostat and oil seals this weekend (Thanks guys for the step by step write ups in the tech section). As seems to be quite common, the bearings on the fan bracket just aren't as smooth as one would hope. A definite wrrrr noise when you spin it. I put the original back after seeing there was no easy fix other than getting a new one for many $$$.

As discussed on other threads, lots of guys spoke of seeing if they could press the existing shaft and bearings out and find off the shelf replacements. Now... I dont have a spare one lying around but someone on this planet must

This is a call to mankind... please try and press the shaft out and see if it can be R&R'd with new bearings... pleeeezeeee..... I'm sure brand new bearings would make our engines even smoother.

I tried, put it in a 20 Ton press... and broke the frame.. no way to pull the shaft and bearings out...

That sucks. I briefly considered putting mine on the press, would've certainly done the same thing if I had.

- Were the bearings going bad, or was this PM?
- How much was the new fan bracket?

 

[PJCB]

Yea real sad... why the hell don't they make these things serviceable.

I saw they were leaking grease when removed the bracket to replace the TB bought a "generic " one at a parts store for $130... that lasted for 6 months... it broke.. the shaft and bearings separated from the bracket frame and damaged my radiator.... then I bought the OEM part for $220 ( and a new radiator)

no problems since... this is the only issue I have had during my 8 years and 102K miles with my 100.

I am telling all this story to tell you go OEM....

I replaced mine during the 2nd 90k

Anybody have one (not broken) that I can dissect? I'll pay shipping, or pick it up if it's anywhere around west Michigan, Chicago, Milwaukee.

Ever find one? Or anybody else been successful at dissecting?

 

[scottm]

No, and I'm coming up on my 200k service.

Mine gave out at 280k miles... just baught another OEM for peace of mind.... one less thing to worry about when driving thru Death Valley!

I've one lying around in my scrape aluminium pile. Looking at it, i see no way to DIY the bearing.

I just did it last weekend I agree I do not see anyway of swapping the bearings out on this thing either.

I recently acquired a 20 TON press and also have old fan brackets from the 2uzfe and 5vzfe. Now, I have a project to do on the weekend! Thanks for the idea.

I had no choice but to use an aftermarket Fan Bracket, but pretty happy with the Dorman version of the part so far. Highly recommend changing it after 200k miles TB service and I will replace probably every 200k thereafter until it rusts away.

Sorry to tell you any aftermarket will not last 200K. So, be ready in about 50-80K miles. One of the Hayden or 4-seasons idler bearing I installed in the drive belt has developed a significant play (had a minor play when it was brand new) just at 5000 miles!

FWIW: None of the Hayden idlers pulley's I installed had play out of the box. I did notice they are slightly nosier than the OEM. Unfortunately The King is gone to it's new home. It was my tester for the bearing, so I've none I can watch to see how long they last.

I do have long term test of a NAPA bearing in the drive belt tensioner, it's outlasting the factory.

Must be you don't have any kids! Keep us updated.

Can one of you post a picture of this part? Front, back and bearing number if possible. I have no idea what this looks like as I have not been that deep in the LC or 4runner. I have good luck with NAPA bearings.

One of my main jobs in the winter is removing old bearings from machinery that has has been subjected to severe abuse. Most are rusted or broken off entirely with just the race left. I can count on one hand the times I have used the press. Most times it just breaks the part as stated above. Usually I soak the race repeadedly with penetrating oil overnight. Then using a vice holding the part I use an arc welder with a bead on the bearing it can be removed with a punch and a BFH. Have some H2O available as the old grease will burn.

Here is a stolen pic off the interenet of a new one the second pic is of the shaft/bearing failure itself on the backside of the bracket

Here you go:

Looks like JAPAN KOYO RR6 (may be RRG) then in small print 614.

One test is inspecting for oil leak. See leak, this one doesn't pass. So this would make this an oil sealed bearing. I'd guess; it's pressed into housing then onto shaft. This would be difficult, even if, bearing can be found. As would be hard to press without damaging the bearing

Getting mine replaced right now, lucky for me the guys noticed it during water pump, timing belt, etc dissection and replacement
