Timing Chain Guide Pin Puller HOWTO?
 

I was asked by email, how the heck does the pin puller sold (I think) by Sir tools work. Well, as shipped, it isn't obvious (had me going for a minute when I bought it) because it is shipped screwed together differently so that parts won't get lost. The two annotated pictures below explain how it is assembled in "working" mode and how it works. You should lightly oil this before and after use. Note the caveats in the pictures about keeping the tool parallel to the head. As long as you do this, and screw the threaded rod ENTIRELY into the pin (having cleaned out the threads in the pin), the tool will work very well. Operate it cockeyed, or only use a few threads into the pin, and something "bad" might happen.

When the job is over, reassemble it to storage (trapping the main threaded part) and put it and the other threaded parts in a bag. I actually STILL have all the parts, which in this house, is some kind of FREAKING miracle.

Thank you for the descriptive explanation and pictures. I was able to follow this already this evening and pulled the rails without a hitch. Thanks again!!

BDBENZ :D

Many of us, myself included, cobbled up a tool that works by using a bolt with the proper length and threads, stacking washers under the head of the bolt, and iterating by adding washers until the pin is out.

Like Kestas said, I just used a bolt with washers, no problems here...

Ditto. Bolt and washers. Cheap. Like me. :D

What's the thread size of the internal of the pin; if someone knows offhand? Thanks.

Isn't there a timing cover fastener that threads into the pin? Just remove that bolt and match up the threads and proper length. I have buckets of old bolts and I always luck out finding what I need off the shelf.
