I don’t really take Golden Week holidays. Beautiful bike weather—should I take a day off? I take time off when I feel like it.
That’s the perk of being self-employed. (*´ω｀*) The breeze is cool and the sunlight is soft—how can I not ride on a day like this? When I revved it up, something smelled a bit like oil… But I tend to put off working on my own bike.
Finally got it on the lift to check it out…
Today’s maintenance & tool log
Vehicle:Kawasaki GPZ550 (ZX550)
Work: Removing old oil seals from the engine (or suspension).
Tool tested today: The seal puller from **STRAIGHT**, a tool maker known for great value. It’s an item that’s been getting buzz online and in the community—”Does that puller actually work?”

This spot tends to leak quite a bit. The outer diameter is small relative to the inner diameter, and the oil seal is thin. It seems like a structural flaw… typical Kawasaki.
And they use that weird metal-shell seal design… I hate it.
I think I had some old stock lying around… Found it! (*´ω｀*)92051-005 I’d like to find a compatible replacement, but I’ll let this slide for today!
Attaching the STRAIGHT seal puller to a slide hammer
The STRAIGHT seal puller I raved about the other day didn’t budge against Kawasaki’s metal shell… My usual homemade slide hammer also struggled…
So I made an attachment to fit the STRAIGHT puller tip and did the work this time. The result was a huge success! This is turning out to be a really useful tool.
When I pulled out the oil seal, oil came pouring out—I panicked.
It’s totally different from Suzuki… I was caught off guard.
Anyway, I’m glad it came out safely! (*´ω｀*) Now future work will go much smoother.
If you’re not confident removing it from the outside, it’s better to remove the cover. But then again, that increases the work by five times…
I applied fluorine grease to the lip section, so there shouldn’t be any issues for a while. Rubber seals go in by hand, but metal-shell ones need to be tapped in.
This OEM oil seal is a bit questionable, so I’ll look for a replacement from another manufacturer. There’s some depth to it, so I’d like to gain a bit more clearance.
Despite being made in a rush, it did its job well.
Testing the Rumored Tool! Removing Oil Seals on the GPZ550 with the “STRAIGHT” Seal Puller.
Vehicle: Kawasaki GPZ550 (ZX550). Topic: Tool review and oil seal replacement. Details: Removing decades-old, rock-hard oil seals from vintage engines can be a nightmare. Today, I decided to test out a dedicated tool that’s been highly rumored in the mechanic community: the Seal Puller from the Japanese tool brand “STRAIGHT”. Using leverage, the tool is designed to hook under the seal and pop it out without damaging the engine case. Verdict: Using the right tool changes everything! With a bit of protective cloth for the fulcrum, the stubborn seal popped right out. It’s an incredibly cost-effective tool that saves a lot of time and frustration. Highly recommended for classic bike maintenance!
