I haven't replaced shifter coupling bushings in a long time. Last time I did one, the shop that was pressing the pin back through the rod cracked the cage, and I want to avoid that.
Any tips, tricks, etc. to aid in pushing the pin back in (like chilling the pin, heating the rod end , etc.)? |

Any tips, tricks, etc. to aid in pushing the pin back in (like chilling the pin, heating the rod end , etc.)? Warming/chilling will help and has no downside. I initially tried using a press but it was awkward and had the potential to break the cage if I wasn't careful -- so I used a hammer. I held the rod/cage firmly in one hand and drove the pin in. I did not rest it on an anvil, I just held it. It worked well without a chance of breaking the cage. |

LUBE.
Heat and chill the parts should slide in like butter. I put the fire wall bushing in a coffee cup of water microwave to boiling. Goes in real nice. |

Thanks for the replies. I actually had an auto repair shop do it for me, as I needed the bearing races pressed in the new front rotors anyway. The service writer (guy who did the work) used to run a Porsche shop. Joe, I tried to install the firewall bushing like you described. I heated it up 3 times in a coffee cup, and it wouldn't go in. It didn't really get all that soft, even after nuking it. I then tried to heat it up with a heat gun, and I 'almost' got it in. Is it possible that the bushing is the wrong size, an inferior grade of nylon, etc.? |

I didn't use heat - I put mine in as far as I could get it in with my hand and then smacked it in with a hammer. Works fine. |
