Jansku99 Posted April 15, 2014 Report Share Posted April 15, 2014 Hi! I have D shaped pistons and head with lugs under 1 & 4 cylinders. I'm doing solid 3F lifter conversion and need pushrod lenght and original parts number for that pushrod. Heard that it was same as 4K-u? We don't have 4K-u's here in Finland so that is why I need parts number to order from Toyota. Will 3K or 4K rockers work? Thank you already! -Jansku99 Quote Link to comment Share on other sites More sharing options...
springersrolla Posted April 15, 2014 Report Share Posted April 15, 2014 I'm at this stage in my build also. i have sourced 3f lifters, and have the twin squish 5k head/bottom end, the pushrods you need are 179-180mm long. 4k rocker gear will work, pushrod needs ball end for lifter cup end for rocker. good luck with it all, i don't think toyota make 4ke/u rods anymore so probably custom. check out toyodiy.com to wig out a part number, just make sure u cross reference them as theres 3-4 diferent rods available 1 Quote Link to comment Share on other sites More sharing options...
Jansku99 Posted April 15, 2014 Author Report Share Posted April 15, 2014 (edited) Toyodiy doesn't show lenghts, but Japan KE70 with 4K-U engine shows part number: ROD, VALVE PUSH 13781-13010 It cross-references to other Japan models with 4K-U and 4k-J engines. European models INCLUDE Liteace with 5K, KE70 Corolla's with 4K and Starlets with 4K. Shows 3F 13751-61020 lifter there too, so I think that it's the right one. When I go to work next week I will ask from our parts vendor - I work at Toyota dealership as mecanic - If they are still avaible from Toyota or do I really have to pay 150€ for custom-made pushrods from Esa Peltonen... How about camsafts, are there differences with hydro and solid cams? If there is, what is different between them? I managed to scrape outer camshaft bearing a little during disassembly, how do you change them as they are in the cylinder block? I assume that there must be some kind of special tool for that as they need to be straight and in correct place? Or should I just ignore that one scratch, maybe sand it down a little with 1000p sandpaper? Thanks already! -Jansku99 Edited April 15, 2014 by Jansku99 Quote Link to comment Share on other sites More sharing options...
springersrolla Posted April 16, 2014 Report Share Posted April 16, 2014 the cam bearings need to be pressed out, not sure if u need a drift or what, i can't comment on the scratch, you know its always there if u leave it but, i had my camshaft reground and it was originally a 5k hydraulic, its been ground for solid, no idea what was done Quote Link to comment Share on other sites More sharing options...
GJM85 Posted April 16, 2014 Report Share Posted April 16, 2014 I had the cam bearings changed at the local engine shop. I picked the block up and there was a score mark in the first bearing. It was likely honed because it was smooth. I was told it wouldn't be a problem. It's been 2 years. Hasn't been a problem. Quote Link to comment Share on other sites More sharing options...
tojo2 Posted April 16, 2014 Report Share Posted April 16, 2014 check out regular 4K from 82,83,84. Most here have lugs under 1& 4 and no, theyre not 4k-u or j. Quote Link to comment Share on other sites More sharing options...
