I use a Deraile cooler with press-on fittings. Just using hose clamps left me with some generous leaks. Using liquid Teflon thread sealer around the male ends stopped the leaks and has lasted for a year so far with no further leak problems. The sealant doesn't harden so is easy to clean up if disassembly is required. Be generous when applying around middle and base of fitting, but make sure that no sealant is at the tip and can enter the line. No drying time so you can test it immediately. I picked up mine at the auto parts store.

I didn't use this brand but here's a link to Loctite's products.

Thanks guys. As always, great info!

I got a nighthawk cooler for basically nothing. Now I am going to blow all the money I saved buying the cooler on Russell SST lines and fittings. I'll let you know how it goes.

What would it take to get this oil cooler to fit on my '79 CB650?

It's off a 1984 CB 650 SC Nighthawk. I have a '79 CB650. Mounting the radiator is no problem, I can build something for that. I just need to know how to mount the "adapter plate" or whatever it's called. The thing that goes between the oil filter and the engine. Would this even work?

hmmmm,velllly interesting

I have been wondering about that too. I did consider buying one just to see if it will fit, but so far I haven't gotten that far.

You'll need the through-bolt and housing from the donor bike.

There are two different ways the "adaptor" plate fits:-
(1) with a short steel piece that holds it to the crankcase and the oil filter bolt fits into this

(2) with a "long" oil filter bolt that goes through the adaptor plate as well so you need an extra "O" ring when you do a filter change

Are these parts that I can get from Honda? If not, where would I find them and what dimensions should I be looking for? Any pictures of what they should look like?

Yas001 · « **Reply #158 on:** July 20, 2006, 09:46:05 PM »

The picture you posted just looks similar to CB750F's oil filter casing. CB750F got double layer casing like this. If filter element is the same as your bike's, I thing just screw both piece in to the crank case... Did you try? Where did you get that any way?

Yas001 · « **Reply #159 on:** July 20, 2006, 09:51:03 PM »

Correction!!
The picture looks like the filter casing is your bike's original and you got only oil cooler out/in put part... You need to get longer...how do you call? the core part of filter with thread on it. I bet CB750F's part will fit. Just like I said on the previous post, CB750F's oil filter casing is double layer, so the core is about 3/4" longer than other CB SOHC4 models. Good luck!!

Pinhead · « **Reply #160 on:** July 20, 2006, 11:19:36 PM »

I haven't got it yet, that's a pic off of eBay.

Is "the core part of the filter with thread on it" like a hollowed-out tube with threads at one end and swiss-cheesed for oil flow? I wonder if it's the same threads... I'd be willing to bet Terry in Oz would know...

Yas001 · « **Reply #161 on:** July 21, 2006, 02:38:49 AM »

If I am not wrong, all SOHC4s are same. Only difference is the length between CB750F and others.

Ibsen · « **Reply #162 on:** July 21, 2006, 03:33:38 AM »

You didn't mention if the oil cooler is from a 1984 650 nighthawk, but the 84 650 Nighthawk and the 79 CB650 share the same oil filter.

See attached photo. This is 1987 CB750F's oil filter unit. Doesn't it look similar to the 650SC's?

Nate · « **Reply #164 on:** October 15, 2006, 10:18:06 AM »

After searching the board here i was only able to determine one thing, the oil filters are the same for the 83 CB650 engine as the 80 CB650.

I've seen a few 83 CB650 oil coolers around ebay. Does this plate match up with the 80 CB6560 oil filter mount? Also if it does match I would obviously need the longer oil filter bolt. Does the thread direction and size of the bolt match up?

Thanks for any expert advice

crazypj · « **Reply #165 on:** October 15, 2006, 10:23:07 AM »

If its a 'sandwich plate' cooler it should come with an adaptor to lock plate onto crankcase and use all the stock parts.
Honda use the same filter on all the (aircooled, non spin-on) fours and the filter housings are the same diameter but different external lengths.

Not being a smart ass, but dummy that down for me a bit. I'm no the brightest bulb in the pack.

The adapter plate attaches to the crankcase then the bolt and cover works the same as the stock one does?

So that would be a yes on the 83 adapter, cover, and bolt to fit the 80???

Thanks for the prompt response

Pinhead · « **Reply #167 on:** October 15, 2006, 10:32:53 AM »

What about the '79?

Nate · « **Reply #168 on:** October 15, 2006, 10:39:15 AM »

From what i've read and people i've talked to the 79 and 80 models are identical on the bottom end. There was some variation on timing and perhaps the cam(don't recall specifically). The 79 model supposedly has a couple more ponies on tap as a result. But if it works for the 80 it should work for the 79.

All of that is of course unless you're watching the same ebay auctions as i am. If that is the case, no it is totally different and won't work

hymodyne · « **Reply #169 on:** October 15, 2006, 10:48:01 AM »

a note,

in my haste for all things good and great for my bike, a 500/4, I picked up one of these coolers from ebay, after reading that it would "probably" fit my bike; in short, it didn't the filter bolt needed, a longer version of the one normally used, will not fit through the standard oil filter housing of the 500. a difference in diameter of about .5mm keps the longer bolt from fitting through without widening the opening in the filter housing.

secondly, the adapter plate for the cooler will not fit the crankcase of the 500 or 550 ('71-76), there are cooling fins on the case that will block the adapter plate from properly seating against the case.

I do want to run a cooler on the bike, but rather than alter my engine anymore than necessary, I bought an adapter plate from terry in Australia.
now the issue is how to adapt the bolt-on hoses from teh stock adapter plate to the non bolt-on lines on the aftermarket plate from down under.

I'm almost ready to chuck the 650 cooler all together, and get either a lockhart or other generic cooler that can be connected to my shiny new plate.
so terry, I may be emailing you again soon...

I know the post was about 650 coolers for 650's just different years, but i also know that other folks like the idea of coolers on their bikes too, so this post is just to try and keep others from investing in parts that they enevitbly can't use.

hense the trip to the experts here at sohc forum

nickjtc · « **Reply #171 on:** October 15, 2006, 11:57:41 AM »

Does a 650 need auxiliary cooling? The oil filter housing (as already mentioned) has a larger capacity than on the earlier engines, with attendant advantages in cooling. It also has a fairly significant oil pump to move the oil around.

If the extra oil cooler is fitted what are the chances of the engine running too cool?

Nate · « **Reply #172 on:** October 15, 2006, 12:26:01 PM »

I do mostly in town riding. It gets pretty hot in stop and go traffic. I can't imagine a small cb650 cooler would over cool the oil.

I've seen those billet oil dipstick coolers, anyone used those? Do they really offer much in the way of cooling?

Not to worry, I don't have enough money to buy one right now even if it went for $10 including shipping...

Well hey i'll be the guinnea pig then, and let you know how it works out.
