Replacement of Sanden A/C Compressor Shaft Seals

This video shows how to replace the front shaft seal on Sanden 5 and 7 series compressors. These compressors are commonly found on Dodge trucks as well as universal Sanden applications.
CORRECTION: FRONT HEAD TORQUE SPEC 23 FTLBS.
Video is for instruction only, we no longer offer the kits. Ebay maybe a good source

10 Star tutorial, Bob you are the man!

ASMR videos are stupid and make me anxious. This is what relaxes me. Tear downs and rebuild videos. Thanks Bob from Century Auto Air Conditioning

[@Poppadee78]

Thanks for this information and great video! Just out of curiosity what oil did you apply while reassembling ?

[@juniemoskito4520]

for sure bob, your videos helps me a lot..thanks

[@DIY-Teacher-Guy]

Great help thank you. A recon pump for my Ford/Mazda is more than ZAR 3900.00 I am going to do my own front seal replacement :-)

[@rajanne2947]

Thanks a lot!

[@spelunkerd]

Very clear explanation from your videos, thanks.

[@johnckyap]

Cool !!!! now i don't have to replace a recon compressor which is always the same advice given by the air cond specialists and use my existing original compressor by just replacing the seal .

[@Probedude2000]

Is the seal install tool larger in diameter than the shaft surface it ultimately seals against or the same diameter? From the video it appears the new seal is pretty tight on the tool.

[@kitastan]

If there is a little scorring or scrathes isn`t it better tu polish the shaft ? I did it on mine just to be sure there will be no leak.

[@Gamerminecraft-j2h]

I can do that without opening the compressor,just install in the outside basically,I made special tool to install shaftseal in the compressors

[@robertdevonald]

Can I ask you a question? Can I change from an A/C sd7 H compressor to aa A/C sd7 V compressor.

[@devinfox4058]

So compressor has to be emptied and removed? Can this be done on a vw w/o removing the unit?

[@bobsteinmann5793]

No, unit must be discharged and off vehicle.

Hey Bob great video. I've done fs10 before with good outcomes but rate now I'm doing a FS20 which has the seal installed from the inside. I ordered a FS20 seal kit part number MT2051 but it didnt come close to fitting (to big OD and to small ID) so I tride a FS10 seal kit MT2035 that fit perfect but leaks bad. any recommendation on the proper seal.

[@zvwxxy]

this is available sanden shaft seal?? i need to replace.

[@brittanyhaynes4510]

I could make those install tools if I had the dimensions of them? Simple bridge port item.

[@lxgadzam]

Are the shaft seal install tools specific to each pump manufacturer and where can they be purchased?

[@sajjadasadpour5943]

Thank you.

[@rafaelmiranda9701]

ty bob , very good go at it about it

[@ariskeram5770]

Does it really fix compressor leaks?

[@bobsteinmann5793]

Nope. Just wanted to do a video....🙂

[@ariskeram5770]

I know you are kidding... 😁

[@Parkerplaysperc]

what size is that big O ring?

[@Omri617]

great video!

[@javidasgharzadeh413]

very good.

[@halleffect1]

will this procedure work on the SD7B10?

[@anansanitchai7818]

Good!

[@lockerpful]

mineral oil is not compatible with R134a refrigerant

[@bobsteinmann5793]

Correct. However the very small amount used to repair a compressor is insignificant. Pag oil draws moisture to itself so it is not used on o-rings seals or fittings.

[@teravolt6113]

@@bobsteinmann5793 Double end capped PAG isn't hygroscopic by the way.

[@teravolt6113]

The mineral oil problem is only that it won't be carried around by the R134A (it will soon leave the compressor without lube; the same problem happens with PAO oil and R134A) but the very small quantity that you put on o-rings and seals isn't enough to cause this problem as long as you fill the compressor with the proper oil type.

WARNING: This video does not show the old type key shaft Sanden, you have to take the key of of the shaft but worse still the knocking out of the seal as shown in the video will break the spring loaded spacer that has a plastic part, i know of 3 people that have watched this video and broken that part, plus 2 of them have also damaged the roller bearing metal holder too. If you have a key shaft on your compressor be very very careful with the shaft seal, it will save you $$$$$$$$

[@bobsteinmann5793]

Many Sanden compressors built before this unit may have a keyed clutch shaft. It is easily removed. Once it is out of the way, the procedure is the same and you will not damage anything as long as you use normal care. Yes you can do damage to the housing , and bearings if you are not careful where you place the tools before applying force. Thanks for bringing up the keyway issue.

[@mohamedakeel3282]

@@bobsteinmann5793I have the old type of seal with Spring loading. Unfortunately i damaged it when i removed. Can i replace with the new type

[@bobsteinmann5793]

@@mohamedakeel3282 yes, the lip seal type is a better option. you will need to purchase a lip seal installer/protector tool to do that. Also, kits come with an aluminum spacer ring that goes under the new seal to space it properly.

[@DortuAirCond_ACmobil]

This needs to be done carefully so as not to damage the seal.
