Oil Cooler on a 82 seca750

1st post here after getting some great info from the archives here. Heres the question; will a Turbo Seca650 oil filtercover/oil cooler adapter screw onto my 1982 Seca750 oil filter threads. I would like to keep my oil cooler when its hot out in the summer. I can't try it out but I can get a setup for cheap.

 

I posted this in mods, but maybe better luck here. 1st post here after getting some great info from the archives here. Heres the question; will a Turbo Seca650 oil filtercover/oil cooler adapter screw onto my 1982 Seca750 oil filter threads. I would like to keep my oil cooler when its hot out in the summer. I can't try it out but I can get a setup for cheap.

 

dunno

 

It should. The motors are more or less the same casting and the same oil filter is used in both. I can swap the bolts on my 650 and 750 back and forth as desired. I'd get the cooler.

 

Thanks, I'll try it out. If it doesn't work I can always ebay it for a little loss or gain. It should help my crankcase from getting too hot.

 

Yes, it will. Go for it!

 

Be sure to get the threaded extension that fits where the oil filter bolt is screwed into. And, the rubber shock-mount bushing that goes on the top center post of the cooler. There's already a braze-on for the bushing right on the frame.

I had to move the horns on my 750 when I put a 900 cooler on my Max. I wound-up with horns on the rear of the bike just ahead of the turn signals.

In Massachusetts, the inspection for horns is a joke. Just as long as something makes a noise when you press the horn button; you're good-to-go.

Leave the cooler on the bike. An engine having its oil cooled a bit is a happy engine.

 

Hey Rick, I've got a question that maybe you....the oil cooler expert!.....might be able to assist me with.

I've got an '82 XJ650 Maxim. Bought a complete cooler assembly off a
'82-3 650 Turbo on eBay. Came with the cooler, lines, and the distribution housing (or, as Yamaha calls it, the Adaptor Plate)----the round cast aluminum piece that the oil lines bolt onto. That's all it came with.

So I looked up all the parts on bike bandit website, and ordered all of the missing pieces, as well as all new o-rings, mounting bushings, clamps, etc.

But I noticed on the part numbers between a non-turbo 650 and the turbo 650 oil filter system that ALL the parts are the same EXCEPT for the outer cast, ribbed/finned "COVER". Before I put all this stuff on and crank it up and screw things up royally, can you (or anyone else?) tell me.....is there really a difference in the outer cover (part #1 in the parts diagrams under the oil filter section diagram & parts list) between a 650 turbo and a 650 non-turbo system?

Thanks!

 

If we're talking about the "Cover" that slips over the Oil Filter.

I think they all have some fins for at least some marginal cooling effect. I don't know of one without the fins.

I looked at a few on the Parts web site ... all looked like they were made from the same mold.

 

Hi Rick.....well, it's the cast aluminum ribbed/finned "cover" that the bypass valve (bolt) goes through.....it's the outermost part of the entire oil cleaner system....it's the thing that you actually see on the engine case.

I looked it up on the XJCD and it says that the turbo model oil filter cover interchanges with the 650 and the 750 Midnight Maxim and the 650 Seca (non-turbo) models, so maybe it's just painted black instead of being natural finish??????.....and that acounts for the different part number?

It wasn't a question of whether this outer cover is ribbed or not.....I would assume that all versions are.....it's whether the 650 turbo and the 650 non-turbo outer covers are the same and can physically be interchanged between such models. So I don't end up hating myself after I crank it up.........thanks!

 

You're good to go ...

The cooler on my Max came off a 900. It's a Big Sucker. But, the lower-end stuff bolted-up easy as pie.

I'm having dreams about ordering the spin-on filter adaptor from Mike.

 

It's a direct bolt-on: everything lines up perfectly. I've got one on my 750/650 mongrel, and the only fiddling was to make a small bracket to hold the hoses to the head.

If you need them, the hose o-rings and the rubber bushing for the cooler's top mount are still available from Yamaha. The bracket to hold the hose is not.

There are at least two different XJ oil coolers: the 650 Turbo's is a bolt on to the 650 Seca non-turbo and 750 frames...the European bikes all came with oil coolers.

The 900's cooler is noticeably taller, with slightly shorter hoses to keep the total length the same. In a 650 or 750's frame, the 900 cooler's two lower mounting bolt holes are ~1" too low, needing a simple adapter.

The oil cooler adapter/wafer is the same for all.

 

Okay Rick and Bosozoku, thanks, just wanted to make sure. My life won't really be complete, either, until I get one of those spin-on adapters too.

Also, I cut the hoses and spliced in a 180" oil thermostat into the cooler system. Fits like a charm. And I also ran across a NOS hose-to-engine clamp set-up on eBay, so everything is now "just right"............

P.S. think a XJ550 Seca front fairing will bolt on to a 650 pretty easily?
Were some type of special turn signal assemblies used with the fairing models?

 

Chacal: Mike O's spin-on adapter has an option for plumbing for an oil cooler. Is that what you need, or do you have it plumbed in using OEM ports?

I did an oil cooler conversion for my KZ but it was a PITA.

 

Spinalator: wish I could get my hands on one of those spin-on adapters. I've had an order in since April (or thereabouts).

I actually have the stock adapter plate that fits against the engine case....it came with the cooler and the lines. I bought all the other little tidbits from bikebandit. My question concerened the outer filter "cover"....the finned cast aluminum piece that the by-pass valve/bolt unit goes through. Is that piece the same between a turbo and a non-turbo model?

 

That I am not sure about.

I have the non-oil cooler spin on adapter. Took a long time, but Mike delivered in the end. I also ordered a YICS tool and he came through a little quicker on that. I wasnt in a hurry so it was no big deal to me, but there a few others that were quite upset with him and he almost said F-it and stopped prodeuction for a while. I really like his work so I thought it was worth the wait.

 

Yes, from what I've heard and seen (on his website) his stuff is absolutely "top shelf". Wish everyone's parts were as good as his......

 

If you're talking about the oil filter housing, the answer is yes. It even fits early FZRs, amd they all take the same paper oil filter.
