well, backwoods, that is exactly what mine was doing, and i just put an IP in last weekend. but i am surprised that there are no codes. when you say it feels plugged up, does it feel like it lost power right now, and sounds different?
you don't have to be EXACTLY at TDC no. 1, just knowing you are there is fine. the gear will have a bit of slop, and you have the slots in the IP itself. that is why you want to look at where the IP nut wear marks are on the old IP. that is a good starting point.
is there a mark where the OS sits? should be on the passenger side. if it is an older pump, it may not have it, but if pump has been replaced, may have a black line.
thanks, mitch, i talked to my local mechanic too. he said the same thing. what is the relationship between TDC offset, and actual IP timing? i think i'll leave it, seems to run well. no advanced ping, and power seems to be about the same.
actual install by a mechanic? probably, 700-900 labor. actual time to install? took me about 8 hours, but was my first time! and peace of mind, as long as it runs, i'm happy! as far as house calls, it may take me awhile to get there! LOL anything for a buck!
now, if you are like me, and you don't have the money to buy a tech2, or any other tool to help you time the truck after reassembly, hen go to you local shop, and ask if he can help you fine tune your truck. if he is like the one i have in town, he hasn't done a bunch of diesel trucks. he may...
now that everything is cleaned and prepped, it is time to install the new pump. there is a small dowel on the pump drive. a newly remanned pump will usually be set to no.1 TDC. it is nice to have that buddy around to watch where that dowel is as you slide the pump into the hole. have him, or...
now that the pump is out, it is a great time to clean around the intake holes, and INSTALL THE IP GASKET. be sure to remove the old one, or you may be disappointed when a leak presents itself.
no, matt, the bolts you are looking at are holding the IP driven gear to the pump. the nuts that hold it on are on the opposite side. you can see them without any dissassembly.
now that you have the back of the pump freed up, you have to free up the front. you have to find TDC no1 cylinder. the way i did it was remove the no. 1 glow plug. have a buddy turn the engine clockwise while you hold your finger lightly over the glow plug hole. when you feel a rush of air...
now remove injection lines from pump. to make things easier, i completely removed lines from drivers side. that gained me enough room to get the pump out.
