Timing marks 2000 Ranger 2.5l missing

[davemmiller]

After the timing belt broke, I had the opportunity to replace it and learn about this truck. wasn't thrilled about any of it. The worst part of all of the process was the rear Timing cover was partial. Basically the plastic around the bolt holes was still there and some parts connected to the front cover.

When setting the timing it was fairly easy until it came to the cam. There are no markings on the block, they were on the missing part of the rear cover. I used the picture in the Haynes manual and placed it at the 5 o'clock position or very close to it, made sure the oil pump was at the 12 and the crank was at TDC (key at the 12 o'clock), released the tensioner and then rotated the crank 2 times listening for noises such as grinding and clatter.

I returned all the things back to their places, torqued them down right and finally put the battery after two days and made sure it was charged. I got in, turned the key, heard the fuel pump and proceeded to crank the motor. it turned over with no problems but never started. is it possible that the cam is off?

If it is a timing issu due to the cam, does anyone have a picture of the rear cover that I can base my cam position on? I do need to get a new rear cover but it'll be a week or two. Now that I know how to replace the belt, it should only take an hour or two to replace it. I also have some other things to do at the same time.

Any advice would greatly appreciated.

First make sure the crankshaft position sensor is not damaged, a very common problem when the belt brakes.
This is the most accurate way to set cam timing without marks. I have used this process for years. the rocker cover has to be removed. With the belt removed turn the cam until the #1 intake and exhaust lobes form a V shape. Balance a steel plate 2" x 9" on the lobes.(I have used a block of 2x4 wood) then measure from the block to the valve cover mating surface and make both measurements equal. The camshaft is now at top dead center. Now turn the crank shaft to TDC (key straight up). Reinstall the belt and set tensioner. Esslinger sells a block of aluminum called a "E" Plate for about 5 dollars plus shipping. Like they invented the plate!!! Sorry I don't have any pics of the process.

Here's the mark for the camshaft sprocket:

You're right about the other two being at 12:00 O'clock as well. Just make sure you've got "triangle to triangle" and "diamond to diamond" and you should be good. Good luck.

Perfect. thank you. I found the piece of the inner cover which is missing the diamond. what a pain this has been. I am pretty sure I have it lined up properly. we'll know soon enough. I found the true timing mark for the oil pump.

upside for now has been being able to make all the adjustments with the front cover off since I am unable to attach it until the inner cover is delivered. I think I'll have the process down to 2 hourswhen I get it. thank you all for your help.

I just noticed the diamonf on the cam. is that supposed to be at the 12?

the cam and the oil pump have the same gear... like above said.. diamond to diamond and triangle to triangle

it dosent matter were the umused mark points
