I reply to every thread Posted May 6, 2004 Share Posted May 6, 2004 Short of ringing Swindon does anyone have a handy " cut out & keep" guide on how to shim the Tappets when converting hydraulic lifters to solid when using the inserts? (ie not "real" solid lifters. Thanks Link to comment Share on other sites More sharing options...
Paul McKenzie Posted May 6, 2004 Share Posted May 6, 2004 Matthew, I reckon you'll get most of what you need from Oily's K-series tuning websire here. Anything else you need and I'd go direct to Oily Paul Link to comment Share on other sites More sharing options...
I reply to every thread Posted May 6, 2004 Author Share Posted May 6, 2004 That all seems to be about K's. I appreciate the theory is the same for VX's but do you have to shim to the individuall cam? Link to comment Share on other sites More sharing options...
I reply to every thread Posted May 6, 2004 Author Share Posted May 6, 2004 I'm revealing the true extent of my ignorance now but what is the purpose of the shim? Link to comment Share on other sites More sharing options...
Sheds Moderator Posted May 6, 2004 Share Posted May 6, 2004 As I understand it on the shim and bucket type cams the purpose of the shim is to get the right valve clearance. If I am not talking about a totally different system from that on your car, you measure the valve clearances and write them down. You then drag the followers and shims out and measure the shims with a mic. A bit of arithmetic takes you to the shim thickness required for each valve and you swap them round/replace them accordingly. As things wear I would expect progressively thicker shims to be required.

Peter T Posted May 6, 2004 Share Posted May 6, 2004 Yes that sums it up, you will find that no two lobes are the same, most xe heads take around 5-10 hours to shim properly from scratch, this time obviously includes grinding each shim which is monotonous to say the least Support the 7 Society......

Swiss_Tony Posted May 6, 2004 Share Posted May 6, 2004 Peter Its good to see that you finally listened James Su77on Se7ens Link to comment Share on other sites More sharing options...
Swiss_Tony Posted May 6, 2004 Share Posted May 6, 2004 Matthew Depending on where you get the shims from they can be bought un-finished in a few sizes. Have a bit of a work out roughly what size you need and get ones which are as close as poss. It saves a lot of time etc having to machine them as much. IIRC Arrow and QED do them in a few different sizes. Not sure about SBD though. Good luck James Su77on Se7ens Link to comment Share on other sites More sharing options...
Peter T Posted May 6, 2004 Share Posted May 6, 2004 Yes james, it does take a long time to do Support the 7 Society...... Ehhh? Link to comment Share on other sites More sharing options...
Anthony Posted May 7, 2004 Share Posted May 7, 2004 Hi Aves, I can recall doing this on 8V twin cam fiat, same process, time consuming and need to grind shims to fit. Lots of assembly and disassembly, but very satisfying when it is done. As James says, try and get understanging of sizes you need and then go shoping with a micrometer. Best regards Anthony Raceco can on and it looks stunning Link to comment Share on other sites More sharing options...
