I think Chrysler called the nylon coating Silent Glide, as it was to make the chain run more quietly. They came in from 1965 on and lasted the life of the engine series. Other manufacturers did similar. It is also quite a saving in rotating mass, being able to use an aluminium gear, although it is half engine speed, and the chain is still heavy. It is good that they didn't bother with a chain tensioner to fall apart!

Any Jensen with the Chrysler V8 and a nylon covered gear, the gear absolutely has to come out, teeth missing or not! Replacements in nylon are not available. It was a hot topic in the 1990s, we assume most were done back then! It is easy to check these days with a phone, pop out the distributor, and stick your phone in and take a photo towards the front of the engine. Here is one I did earlier :shock:! Looks like this one is due!

Quick question John, where did you get the Gasket seals from - usual suppliers or eBay?

I normally buy a couple of FelPro full engine gasket sets $60 or so, from Summit racing or Jegs in the USA and pinch bits from those, and a new valley pan tray which is not included, which I then reuse. I like to order a mechanical fuel pump and a couple of sets of alternator brushes, starter motor brushes, and two sets of blue Streak contacts breaker points and condensers for Mk1's. I do reuse Blue Streak points after dressing the contacts and keep them on the same distributor. Basically light stuff that doesn't cost too much to post. I am startingto experiment using decent quality Silicon sealant on some joints, after finding that the Range Rovers of the 1990s switched to no gaskets only silicon, so I have some of that to experiment with. No results yet. I am often out of the UK so having Mopar bits shipped from the UK doesn't make sense. I do save the old iron water pumps and want to rebuild them with new seals and bearings once I get a decent press setup, but for convenience a modern alloy pump with stainless impeller is sensible, but I don't mix delicate gaskets and heavy items in the same international parcel anymore!

Please can someone tell me how to take out the plunger / valve. Circular Clip removed so thought it would just pull out. Hoping to replace the seals.

Kind regards,
Karan

Karan, look underneath those plastic node inserts, you may find a circlip or similar, I haven't stripped a FAG one but that is where it is on a Girling oneImage

Hi Grant, I have removed the circlip and a retaining washer behind the circlip but I still can’t pull the plunger out with the plastic nodes. Strange to say the least - will dwell on it for a bit!!

Grant, are you saying that I should remove the plastic node and that there could be another circlip behind it?

Yes, I can't promise, but maybe under the rubber grommet, go careful with those plastic nodes though Karan because they can go very brittle, on a Girling Master cylinder on a MK2 under the reservoir inlet closest to the servo there is a circlip..so I was guessing the sort of same for the FAG one :wink:

Karan... there is nothing under the nodes, you need to use a little compressed air, look here >>> viewtopic.php?p=204742#p204742

Thanks Grant and all others on the link. Got there. The compressed air did the trick and it was spectacular.. The back plunger was not coming out but I noticed that it was held back by the center bolt on the main body of the cylinder - guess this is normal / the norm.

Compressed air worked a treat. There is a bolt on the outside of the cylinder that is screwed down to hold the rear spring plunger in as you compress it. This allows you to then compress the front spring / plunger (yet to work out how to do so - will likely clamp it down) to fit the back retaining washer and circlip..Anyway, do I undo the bolt on the cylinder slightly to release the rear spring / plunger after it is back together or not. It was left screwed in when I took it apart but I am not sure if that is right!!!

I should imagine the bolt is supposed to fit into the gap of the plunger Karan to allow movement backwards and forwards as you need movement, but also to keep it at a position not allowing it too far forward, but lets see what others sayImage

Good idea, I have put it back to how it was for now. The tip of the bolt is holding back the plunger and it is fully screwed down. This puller that was used for pulling off the timing belt wheel was good at compressing the springs to get the final washer and circlip in. It’s a lot stiffer when I try to push the plunger in manually.Will put back on and bleed and test later.. Thoughts on that bolt from anyone would be appreciated. Kr Karan
