Post subject:  King pins
I'm the midst of fitting new king pins. About the third or fourth I've fitted to various 2cvs over the years.

The drivers side was straightforward but the L/H one is causing a problem. Firstly I hand to grind down one of the shims/washers so I could fit the dust cap thrush washer and 2 shims in. I centralised them with the ECAS dummy pin from underneath. Hub moved nice and free, a fraction of vertical movement. New king pin banged in but is now stuck solid at the point it's entering the bottom bush and the hub also stuck solid! :? The king pin passed through the bush prior to fitting.
The hub may not have been the one I took off but I can't see that making any difference. Can anyone please offer any advice? It's a mystery to me. Am I missing something glaringly obvious? Thanks in anticipation of being embarrassed!

The kingpin could have expanded at the top, because of the hammering, and is then running stuck in the top bush, or some metal of the swingarm is scraped off and got stuck in the lower bush.
Hammer it back up, and measure the top diameter of the kingpin.

Thanks for your input AZS. I follow the logic there, the drift has certainly deformed. I'll have to take the arm off to give me enough room to hammer the pin back out. I'll let you know how I get on!

If the top of the king pin is mushroomed, push it back out not through the arm. You run the risk of removing tiny amounts of ''meat'' expanding the hole. Then standard size 17 mm pin will be loose. Also place cobber or bras washers between the drift and king pin to absorb the shock.

Thanks for advice Viking.
Found the problem after taking the arm off. Looking from the underside I could see broken metal. On extracting the pin the thrush washer (the one with the grease grooves) had disintegrated. With my continual hammering I was forcing some broken washer and pin into the bush, consequently jamming the swivelling joint and pin. Don't quite understand why this happened as the dummy aligning pin was (as I thought) keeping the washers and dust cap in correct positions. It was held in place with some dense foam so as I hammered, the dummy pin was being absorbed into the foam.

Thanks again for the advice

the pin in the kit is too loose - use the old KP

There isn't any dummy pin in the tool kit. They are aligning tolls for top and bottom bushes. As Sean write, push the old pin in from underneath to steer the washers etc

According to the instructions that came with the kit (ECAS some years ago now) step 14 "............insert dummy pin (shortest rod), check vertical clearance, step 15 ......remove dummy pin then coat in plenty of grease and re-insert and support underneath by something that will give as the pin is knocked through....."

Tool number 6 is to align the bushes not a dummy king pin. Use the old pin
