TJT Vario Spring/Honda PA50II Rear Pulley ??

King Drunky JCams /

Hey All,

A quick question for those who've cracked open the rear "driven pulley" on a honda hobbit to install a TJT spring.

I might be getting a TJT variator... I wanted to be prepared.

So, I removed the driven pulley using my handy honda tool #07933-1480000 and it was super easy.

Upon inspection of the pulley, and upon looking in the manual I've got, I noticed that another honda tool is used in in opening the rear pulley to get to the spring inside...

First obstacle, I don't have a socket that huge for the nut on the back, it's gotta be a 26 or bigger... What did you use?

2nd challenge: find honda tool #07933-1480100... DO YOU HAVE IT?

Let's talk if you can help me out...

Thanks in advance.

Thanks Ed.

This pic should clear up what I need.

Looks like removing the pulley in the last step can be done on an arbor press or a hydraulic press or possibly in a vice if you are careful.

Re: TJT Vario Spring/Honda PA50II Rear Pulley ??

I heard you can order the tool from any honda shop. I also heard that tjt spring is way too stiff.

Re: TJT Vario Spring/Honda PA50II Rear Pulley ??

Its a easy tool to make.

Looks like you will have to make the tools just need to know what size the threads are research you have a welder :)

I used this tool with a slide hammer btw.

Yeah Tommy, you actually told me that once... so, in conjunction with my scooter shop friend, I might have found some other alternatives...

For now, I just wanna crack this bitch open!

Also, I plan to call the local honda shop where I bought my other honda tool... they actually had the PA50II clutch tool on the shelf all dusty and forgotten... I was shocked!

Ed, not sure I can see all the bits and details, got any more pics?

The derbi is alot easier to switch that out. The tool I made also removes the clutch same thread.

I will buy the spring as I want to snap a crank :)

The pulley puller was unavailable on www.bikebandit.com, couldn't even find the other part # try www.hdlparts.com

Re: TJT Vario Spring/Honda PA50II Rear Pulley ??

nooo, dont waste your money on that puller...

Re: TJT Vario Spring/Honda PA50II Rear Pulley ??

...give me one sec and i will type up a way to disassemble the rear pulley

Re: TJT Vario Spring/Honda PA50II Rear Pulley ??

hold the pulley like this:

i used rope rather than the belt

then insert a wooden dowl, or something similar, into the hole and beat down on it with a mallet. it just needs a sharp wack and the whole thing will come apart. it will most likely spring apart and end up somewhere on the floor but there arnt many parts to it so you shouldnt lose anything.

i think that picture is one of silverfox's, i will try and find the original thread

Re: TJT Vario Spring/Honda PA50II Rear Pulley ??

wow, dunno why that post didnt work.

hold the pulley like this:

i actually used a piece of rope, but you get the idea.

then insert a wooden dowel, or something similar, into the hole and beat down on it with a mallet. one sharp whack should cause the pulley assembly to fly apart, it will probably spring across the room but there arnt many parts so you shouldnt lose any.

Re: TJT Vario Spring/Honda PA50II Rear Pulley ??

right, why isnt that pocture working?

the rest of my post reads:

i'll try the picture one last time, and i'll also attach it

joew was the hobbit/pa50 tech from what I have read.

Re: TJT Vario Spring/Honda PA50II Rear Pulley ??

Has not been around these parts for years.

Re: TJT Vario Spring/Honda PA50II Rear Pulley ??

What ever you do be very careful to not bend the inside moveable sheave. It is very thin and very easy to bend. I speak from experience. They are impossible to find also.
