Oil is seeping from the oil cooler fins!
The new one is discontinued, so I spent several minutes patrolling Yahoo Auctions.
Used parts on Yahoo Auctions are expensive, which isn’t ideal, so it’s a tough call.
It’s important to look at the photos and feel the seller’s kindness. Also, keep in mind the risk of failure when considering the price—it’s deep stuff!
Lately there’s a lot of it on Yahoo Auctions. Oil-cooled bikes are old too.
Now, I’m reusing images from the CMS.
The component parts are basically the same, so I’ll compare them.
| GSX-R750 (GR71) including RR GSX-R1100 (G/H) | GSX-R1100J (special? countermeasure?) | |
| Oil cooler assembly | 16600-27A01 | 16600-06B10 |
| Right hose | 16470-06B00 | |
| Left hose | 16460-06B00 | |
| Union bolt (top) | 09360-16002 |
Oil cooler assembly
GSX-R750 (GR71) including RR, GSX-R1100 (G/H) 16600-27A01
GSX-R1100J (special? countermeasure?) 16600-06B10
Only the J type has a different part number, but it’s interesting that G/H are the same.
Oil cooler hose
GSX-R750 (GR71) including RR: right 16470-27A00, left 16460-27A00
This appears to be 750-specific.
GSX-R1100 G–J: right 16470-06B00, left 16460-06B00
This appears to be 1100-specific.
Union bolt
09360-16002 (common after part number change)
Looking at it this way, I thought the J type was special and could use anything.
Roughly speaking, when I measured with a meter, they seemed to be the same.
The number of stages is the same too, so I thought they were identical, but actually they’re subtly different.
• The height of the boss where the union fits is higher on the J type (roughly 10 mm, unmeasured)
• The oil cooler mount (lower) tab is shorter (it would be loose without extension).
It works, but without extending the tab it becomes loose.
What was supposed to be a simple swap ended up taking some time.
If your oil cooler is broken, it looks like it might work but actually doesn’t—maybe it’s a trick question.
It’s deep stuff. What exactly did the J type cooler improve anyway? A mystery.
