435 injector

[Anonymous-0]

I changed injector up to the s-35 injectors I timed them the same as the manual said too, but I get a lot of white smoke and its hard to start, should they be timed different?

S series injectors are junk. You want the N or C series.
Which tool did you use and what spacing did you set the injectors too?
As long as the 17 to 1 S series pistons and sleeves are in there.The engine won't fire when cranking on the starter at temps below 45F.The 21 to 1 N series are required.
The cam follower and valve springs will be weak too. They need to be upgraded with the latest from Detroit Diesel.

When you say you changed "up to the S 35", what injectors were in there?

Iguess I got comfussed on the information on all the posts on this subject I should have went back and read them again ,I thought that they came with N-parts and the upgrade was to S-series.Ibuy parts from PC industry and stewart & stephenson and neither one have listing for n-35 injectors, the injectors I pulled out just had 35mm ,I used the J1242 to set the new ones,It is around 40 temp here, I had a 435 that put new sleeve kits in and injectors and I just had the parts man get the factory parts ,and it would fire as low as 35 temp,so right now for my set up Ijust reringed it ,sleeves were good,end gaps good,do I have the right injectors?and I probably need to check my compression.

It will NEVER EVER EVER start worth a darn or run without smoking. Until the p.o.s. S series injectors are traded at the DD counter for C35's.
"S" stands for "Smoke".

The compression will NEVER EVER EVER be worth a darn with the p.o.s. 17 to 1 S series pistons.Nor start worth a darn. Until it's 21 to 1 with N series pistons.
If you ground the valves and seats which sinks the valves into the head.Which increases combustion chamber volume and lowers compression;therefore reduces ignition heat while cranking.

DD parts are noted for being cheap and readily available. You can get an entire DD sleeve,piston/o'ring and piston ring set. For less $$$ than just a set of rings for most other diesel engines.

Don't forget the blower seal and cam follower/valve spring updates. It's a shame when a freshened engine puts a valve through a piston.Or has a runaway that ends with a bang.

didnt mean to hit a nerve, The cheapest I can find kits for 2-53 are around 300 a hole a set of rings 60,are you seeing kits for less.
