Hello, i need to replace or do a overhaul on my steringservo pump, the pump have 3 intakes/outtakes, i have hydraulic brake servo too.. and i feel the brake is a little bad now,and i dont have no steering servo left.

i have search for overhaul kit for this pumps but can only fint sealing kit? what is bad in a pump when it not work good if any knows? thanks for answers..

Have the pump a product number that i can find easyer a identical pump?

I assume this is for your 1979 D88. There are several rebuilt pumps listed at Rockauto.com, both with and without the reservoir. Your old reservoir is easily swapped over to the new pump body if you choose to go that way. I assume your pump looks like this:



Of course your problem will be, does RockAuto ship to Norway?

Seff

They ship to Denmark, so I think they will.

Oldsragger

Oh, thats look what i needed! i will see if they can ship to norway too.. do you have the part number on this? cause when i search on the 81model 307 5.0L and 79 D88 i dont find the pump with reservoir. i dont know what is custom or orginal on my engine so it have not been so easy to search for parts. do i need to shift the pulley wheel too?

Oldsragger

i found a better pic of my pump..this is the same...found from a D98 350 diesel



i think i will order this

joe_padavano

I assume your car was a diesel originally, as only the diesel cars used the hydroboost brakes. When searching for parts like this, you will usually need to search using the original engine, not the current one. Looks like you found it, however.

Oldsragger

Yes that is true,in the car document it have been a 350ci gas engine before so i think it have be a replacement engine, and it have been smallblock chevy and now the little 307ci. is it normal the hydroboost will be weaker when the pump is bad? cause i feel the brakes be a little bad... the rockauto.com ship to norway but it was a little expencive..i try to give a search on ebay on same part number and i found the identical steering pump, so i have order from there now it will be nice to get back the unmucle servo again

anyway thank you very much for the help!..

Hello again, i use this same tread to ask my question ,i don`t know what the last owner on this car have done on my olds 307 about what is orginale ... today i removed the steering pump and remove the alternator bracket, the steering pump bracket and one smaller bracket....i add a pic of this...can someone tell me it the small bracket is orginal for this engine? it seems to can fit cause the hole in the engine block and like that.... the reason i ask is cause the steeringpump pulley have stand very wrong ,and the other pulleys standing straight on line.. i have only 1 v-belt for all the pulleys, but i think it should be one v-belt for steeringpully and 1 v-belt for the alternator. i only use a big v-belt now for all the pulleys and the steering pump pulley have not so much contact on the v-belt .. does any know what is the orginal v-belt size should be for the steeringpump pulley to camshaft or fan pulley?

my v-belt today look like this...

Bracket for the alternator, on the downside..

Is this small bracket nessesary?

To answer your question of "is this bracket necessary?", absolutely. That small bracket runs from the bottom rear of the PS pump to the side of the block and is necessary to maintain proper tension on the belt. More importantly, there are two spacers, one that goes between the pump bracket and the front cover of the engine on the bottom bolt and one that goes between the side of the block and this small bracket. Use of these spacers is mandatory to get your belts to line up.

Oldsragger

aahh i see, ok, yes i found 2 diffrent spacers, but the bolt in the block for the small bracket was not there, i will try to find a bolt that fit,and spacer. then i think i have all the parts i need anyway. i just was confused cause the pulley from steering pump was not on line with the other pulleys, maybe the reason is not right spaced with spacers. hmm i will look closer.

Oldsragger

Hello, here is some few pics of my spacer, i think this is the orginal?

IMG-20130907-01624_zps363ee176.jpg

I tested the small bracket today, i found a bolt that fit in the engineblock too.. but i see it is space between the spacer and the bracket in the front... so i think the big bracket should stay between like the picture?

IMG-20130907-01626_zps14aaffd4.jpg

And here is the thin spacer..it stand right here?

IMG-20130907-01628_zps3148b030.jpg

joe_padavano

The thin "spacer" in the photo is a washer. You are missing one of the correct thick spacers.

Nope. The spacer goes on the stud first. See the drawing in this thread:

https://classicoldsmobile.com/forums...p-spacers.html

Oldsragger

oh, ok, so maybe i only have that small spacer, and have to find something that could replace the big spacer then.. if i can just use the washer with the spacer in front..maybe it will be thick enought... that tread u gave me was interresting.. hmm i see he write about the size, but what is the height in MM (millimeters) ? :

Large spacer, goes between block and rear-projecting "wing" of pump bracket, at hole that is the frontmost of three that could hold a motor mount:

0.402" height
0.467" ID
0.816" OD


Small Spacer, goes between timing indicator and lower front hole of pump bracket, at stud that goes through the top hole of the timing indicator:

0.631" height
0.400" ID
0.563" OD

joe_padavano

Multiply by 25.4

Oldsragger

thanks.

well anyway, now i have found out what i need, i need 2 small v-belt of same size from crankshaft pulley to water pulley, and one new v-belt from waterpump pulley to steeringpump and alternator pulley. if i choose this method i will get the v-belt on line.

i can understand what the old owner have done with this v-belt alternativ that was before,and spacers on other places that should be like orginale,with only 1 v-belt.

Now i hope i have done it like it should be. (i use some washers to replace the orginal spacers)

Looking good. By the way, I've done exactly this in the past when I couldn't find that lower rear spacer:

jcdynamic88

I don't believe your belt routing is correct,outside (largest) groove on water pump should only drive the alternator,next groove in should drive the power steering pump and inside one is for a/c compressor.the outside groove should only go to the alternator and not the power steering pump.

Oldsragger

Ok yes maybe, i dont have A/C or sign that it have been a/c in this car before,so i dont know :/ , but if i could have it work like my plan is now, will it be a risk for the v-belt been destroyed? im thinking most of the inner v-belt from crank to waterpump pulley,maybe i should install a ticker v-belt ,cause this i found is a little thin i see... anyway i will have it better than it was before i hope.

i will see when iv got the 11x1200 v-belt i will try it from the outside groove from waterpump to steeringpump and alternator to see if the vbelt will be on line.

jcdynamic88

jcdynamic88

the "washer"in the picture is the correct "spacer" for this application on the p/s bracket to side of block,because this car was originally a diesel it has a bracket between the motor mount and block that acts as part of the spacer.the thread you directed the op to is for a gas engine and the spacer is different.

Oldsragger

aha ok, maybe that is the story, but if it was a diesel car before,do you think it have A/C before too then? i dont know..maybe it have a a/c delete kit,and new fan cover in the firewall. sins you told me about the diffrent pulleys.

in the paper of the car with car information, that should stand a 350cid 5.7l gas engine in the car.. but maybe that was the engine who was replaced after the diesel. the gastank have gaslines forward and backward before too.

jcdynamic88

although i'm sure it's possible to come without a/c I've never seen one of those cars without it.i don't know how you can have the belt go on the outside groove of the water pump and on the power steering pulley with proper alignment.why wouldn't you just put the belt from the water pump to the alternator as it was meant to be?the correct belt for the alternator to water pump pulley is a 7430 and the p/s belt is a 7445

jcdynamic88

I've never seen this vintage olds with hydroboost that wasn't a diesel originally,i believe the 8th digit in your vin would be a N.

Oldsragger

Hmm the reason i don`t can use the outside waterpump groove on pulley to alternator is cause i will not have the steering pump pulley on line with the groove in the middle, so if i use the outside groove i can have alternator and steeringpump pulley on line. I have a v-belt now that fit outside groove to alternator that i just tested,,its was about 11x1905mm i think. i will search for that numbers on ebay,thanks.

if i should use own belt for alternator i must modefied the spacers again and the steering pump pulley will not stand on line. anyway i will see better when i have install the steering pulley on

jcdynamic88

I can't help feeling that something is being lost in translation but based on the pictures, you have the right pulleys and you are not that far off on the spacers,you definitely have the correct spacers for the side of the block if you put them in the right place,it appears you don't have the exact one for the front lower mounting.are you sure you have seated the pulley on the pump all the way?if you have it shouldn't line up with the outside groove on the water pump.i think if you don't have two belts you will have problems driving the p/s pump and alternator without slippage.

Oldsragger

Hmm i don`t know, i will wait for the new v-belt that i have plan to test on the outside groove, and test how it will work, i install a second v-belt today from crank to waterpump, i will buy the 7445 v-belt too,or a belt in same size,in case i have to use the middle grove for only p/s pulley. I just have to install the p/s pulley on the pump first, then i can see better how it will fit with the grooves on the waterpump.

This is really a mistery, nothing fits when i try to use the orginal spacer method, well so i install the bracket like it was before, and i use 1 v-belt from crank-waterpump-servo to alternator pulley, it works ok, iv got the orginal belt size for the servopulley, it would be the best option,but then i have to move the alternator on other side of the engine like this pics of the first alternative...



or build the alternator more forward,cause the alternatorbelt from waterpump outside grove hit the servo pulley.. anyway..i made me a homemade install tool for pulley too..

This was the first alternative i do, but the v-belt slip on the alternator when i steering left or right or use the brake,it was to noise for my ears,




the homemade tool,i welded a big bolt on a smaller bolt that fit the crank,weld a big washer on the outher ring of the bearing that not hit the inside ring,then i use a smaller washer for the inside ring on other side:

IMG_20130921_170738_zpsc828a26a.jpg

and this is why i could not use own v-belt for servo pulley, cause the alternatorbelt hit the pulley in worst case i could build me a new alternator bracket for the other side of the engine if i will do that... but now it work great with the old alternative i have..
