Oil cooler

[Flash]

Any ideas on putting an oil cooler on a motard. I want to increase the oil capacity (hopefully double it) as well as keep it cool when the turbo goes on.
Ideas!!

:edit - moved this thread to the workshop section:

On my XR600 powered supermono I stuck an earl's TT350 oil cooler on it (which I got from a wrecker), although this was fairly small and wouldn't add much in the way of capacity. The whole oil system on the bike was hand made by me though, so it was basically guessing at the best of times! :D I've got some web space dedicated to it here (http://members.iinet.net.au/~nmilne/supermono) if you're interested.

BUT, what you're talking about does sound like a fine idea. Mount the oil cooler somewhere under the steering stem, run the oil feed from the output of the oil pump into the cooler, then back in to the oil feed into the tank in the frame. You'd pick up a bit of capacity from both the cooler as well as the braided lines it runs through, but if you really wanted to get tricky then you could build in an aux oil tank into the thing as well rather than relying just on the capacity of the side tanks on the rad plus the rails.

Hey Ash are you having trouble with the Husky, why do you want to put an oil cooler on it? What brand of oil are you using and how often do you change it?

I think that says it all :D :lol:

I had a look at your supermono project. I didn't realise that you were so hands on!! Have you still got it?
Did you do it for a reason (to race a class) or just to see if you could?
I have to look at how to get oil from the pump and then return it. There is no provision for the to leave the engine except the oil pressure line going to the head. Which I'd rather not use. I want oil there as quick as possible when I start it in the morning.
I'm getting the manual out tonight to see what I can do. :up:

Yeah, still got it, still sitting in a corner of the shed gathering dust :roll:

I actually built it because the supermono class sounded interesting and I thought about having a bit of a go at some club racing, even as slow a plonker as I am. Unfortunately by the time I got it on the track the class had well and truely died in australia :cry:

Isn't the husky a dry sump motor? I just assumed it would be ... if it is then there should be a feed going out to an external oil tank (typically the frame, behind the steering head) which you can use. If the husky motor is wet sump i'd be surprised, but it might have some ultra trick internal baffling or pumped reservoir?

The only problem I had was that the fittings were specific to the thread and size of the taps in the frame, so I ended up cutting the end fittings in half and having someone silver solder on some new ones which matched the braided line I was using, then ground down the sides so I could get an open ended spanner on them when doing them up...

No mate it's wet sump no oil tank on this puppy (doh)

[Wobbly]

Are you sure its wet sump? I didn't think they'd made wet sump dirt bikes for years ... according to the husky site the SMR450 is dry sump (http://www.husky.com.au/2004bikes/motard/sm450r/sm450r.htm). If it were wet sump I'd have thought it'd need a way big oil capacity and some fairly serious internal baffling.

Can you take a look at your bike at the location marked below and see if that's an oil line? Maybe they're just well integrated and harder to see than your standard dirt bike ones?

Nup, definately no oil running through the frame on this puppy.
It maybe scavenges from the gearbox and uses that as a reservoir?? :shrug:

[Wobbly]

Hmm, very interesting ... what it might do is have an internally cast gallery that actually acts as a separate oil tank ... honda do this on their ultra trick RC211V motogp bike, so if it does you're in good company!! 8)

So where do you fill the oil then, is that the main filler just above the clutch?

[Wobbly]

In any case then getting an oil line to run externally will likely be a bit of a nightmare ... we're talking engine out, cases split machining type of nightmare, unless you could use something like the oil feed line from the filter to the head, but then you need to start looking at the amount of impedence you'll be introducing with the filter and whether the pump is up to it and whether this could have an affect on something else, such as a filter by-pass circuit or flowing more oil to another part of the system ....

Do you have a lubrication system diagram? There's normally one in most workshop manuals ... which i'm sure someone would have scanned up on the internet somewhere...! :lol:

I was thinking that I may have to increase the capacity of the pump, but I'm not sure yet. I had a feeling that I may have to do some welding for the oil return etc but I wasn't sure yet of the details. Good idea on the oil gallery diagram, I'll look into that.

I found a sight that has a picture of a smr 450 that has an oil cooler. somewhere in the freaky text it says that they believe that it is Eddie seals X game bike( this could be bullshit though :? )
Any how here is the link.
