It states I have to remove the camshaft pulleys as well to get to the rear timing cover in order to replace the h2o pump. Is this true for a b18b?

Just wondering if anyone had the helms diagrams scanned.

TIA

 

Anyone??

 

The water pump is driven by the timing belt, so you will have to remove the cam belt cover and also remove the belt to replace it, its held in by 4 (i think) 10mm nuts and is fairly simple to replace.

 

Good luck getting the crank pulley bolt out. I think my was torqued to over 300 ft/lb's and it took a 3/4 ratchet that was 18 inches long and my dad who weighs 200 putting all of his weigh on it to break that bolt loose. PITA I'd have to say. Three different impact wrenches didn't even come close to breaking that bolt. Plus, this was with the motor out of the car and on a bench.

 

Spray some Metal lubricant on it and let it soak for a while.

 

Spraying metal lubricant on the crank pulley bolt won't do anything. since the crank pulleys are in the way and there is no way for the lube to get anywhere near the bolt, you'd be wasting your time.

 

Use an air gun or get that crank pulley remover for like $65.

 

I used three different impact wrenches that wouldn't touch that bolt. since that was the last time i plan on doing a timing belt in that car, I didn't feel that the 65 bucks was worth it.

 

I don't have a Helms diagram scanned, but it does say to remove the camshaft pulleys and the back cover to access the water pump.
Here are some tips I posted on doing a TB/WP job on a 94 GSR B18C1: https://honda-tech.com/zerothread?id=421701
As far as the crankshaft pulley bolt.....if you don't have access to air tools, dont even start the job. Every mechanic I haved talked to from shade-tree backyard types to Honda Dealership techinicians say those things are a bitch to get off. I dont even know why they bother selling that stupid $65 crankshaft pulley holder. I mean, if an air impact wrench can barely get the bolt off, how the hell could a person apply that much force? The tool is just a pulley holder to keep the crankshaft pulley from turning while you "supposedly" loosed the bolt. The only problem is you need to be like Hurcules or Arnold to get it loose by hand. If you have a friend at a shop or who has air tools, get them to pop the bolt, then tighten it back at say 200 ft lbs and take an easy drive back to your garage. Then, you should be able to get it off without an air tool using breaker bar, whatever.
By the way, I could not get my crankshaft pulley bolt off until I removed the extenstion I was using on my air wrench. Once I took off that extension - bam, it came right off. I was using a Sear air wrench rated at 600ft lbs of takeoff torque running on a 6HP 150PSI sears compressor set at 95 psi.
Good luck amigo !

 

Nah, the crank pulley remover tool works fine. Got mine off. Just use it and a breaker bar.

 

Get the Moroso crank pulley tool. I have broken loose plenty of crank pulley bolts with it. Motors with like 200,000 miles on them. And believe me, I'm definitely not hercules. And yes, you do have to remove the cam gears, because you have to remove the timing belt cover.

 

How difficult is it to break it out with the pulley tool? I am not muscular but I would definitely want to do it myself instead of paying someone to change my belt.

 

Moroso crank pulley tool is worth it's weight in gold if u can use it enuf to justify it's cost
