LAN e9 empresas y tribulaciones, an epiphany in 042BBlau. OPUS MAGNA. XXXXXXXXXXXXXXXXXXXXXXXXXX

of oil pumps, oil dipsticks,

I have put a new oil pump, two surprises and an anecdote

The first surprise is that there are no pumps on the market, normally you have to renew the one you have or look for another used one, good luck with it! it is not easy to find

the second is that the new replacement pump (which I bought 6 years ago) is different and does not fit, let me explain...

This is the new replacement model, it changes the fastening of the front sprocket going from a plate with three screws to a single central nut, (by the way it is rare metric and rare thread step)




In addition, observant people can see a prominent cup in the suction end, and this is the other surprise, it does not fit in the carter, so you have to cut the cup, it does not look elegant, but it is worse to leave the carter open ;-)





here with the bowl cut:








And now the curiosity, I have wondered how the oil dipstick looks down there, well this is the answer...

matching the level (in the photo the engine is not level as it would later be in the car)


this would be approximately the situation of oil level in the middle




and one last thing that I have learned, and that is that the pump must be assembled with oil so that it is primed, otherwise it will not suck...

BTW, i do have 8 nuts for sale, i was forced to buy 10, i installed one and i will keep one as a spare, so if you plan to install this type of oil pump and you need a nut, do not hestate to ask for it. buyer will pay postage.

the old version...




some details....


- in green the old system with three screws
- in blue the old type suction cup
- in red the two distancers that must be placed to get the correct tension

plan to install anciliaries and renew eccentrics and make a nice valve adjustment calmly
 
some more...

careful, this will fall down when upside down

the seal sits flush with the wall, see the needle bearing below

to extract this one use a proper stick and hit from the other side

to extract the needle bearing and the seal use a 18mm hex vase, and a proper tool to not hit it with a hammer

this setup works very smoothly

if you place a piece of paper pressed upon the cage, the needles will not fall down

hi, @Stevehose

i do have a concern as i found a discrepancy: the position of the saft seal in the steering pump, as i have seen in your pics (see below)

it seems that you put the lip with the spring on top:

but as per my pics on disassembly it is clear that my seal appeared to be mounted just the opposite:

once extrated you can see the seal to identify the sides:

now see the seal and see the spring on the other side

IMHO, you should not tap the rubber side when introducing a seal, as you did (@Stevehose ), that is why the seal has a steel cage to be pushed from that side


comments ?
 
another point @Stevehose

you did a profoundness gauge check

in my case i found the needle bearing to be simply bottomed in place, and found a gap between bearing and seal, see here:

can not tell the relevance

regards
 
I probably put the seal in backwards unless it happened to be that way upon removal for me, fortunately no leaks and working fine all these years. I did the measurement per the manual instructions and I definitely had room for adjustment before bottoming out. Great pics.
 
Gear box speedo pinion and seal

you probably will remember this pic from @Stevehose

He was the first to tackle this job

so I have done it myself

you can see the old black rubber seal still in its place

the small steel sort of thick washer is out a bit PITA by the way
