Sanden 508 R&R

uzzo2 on Wed March 26, 2008 11:23 AM User is offline

Year: 1986
Make: VW
Model: Golf
Engine Size: 1.6L D
Refrigerant Type: r-416
Country of Origin: United States

hello all, i'm new to the forum and needing a little advice. i have a 1986 VW Golf with a 1.6L diesel that i got in 2001 from a friend. the a/c did not work when i got it so i ordered a new expansion valve and drier and charged it up with r-416. it worked great, would freeze your nose off it got so cold. however, its had a lot of other mechanical problems that has left it sitting quite a lot over the last 5 or 6 years. i think i now have all the problems straightened out but no a/c. i tried to charge it the other day and the shaft seal is leaking on the compressor, was leaking so bad that it was pushing the oil out. the compressor is a sanden 508 model#9288 which has the horizontal suction and discharge ports. i have searched extensively and can't hardly find a new one and the remans are $250-$300. i've seen several 508's on ebay for less than $200 but they all have the vertical ports so i'm wondering if i could get 2 male to female 90's and put that compressor on with those ports facing the ground, screw the 90's on and then my hoses and a new drier. or, i'm also wondering if that won't work could i exchange the rear head from my compressor to the other without any problems. i'm not doing a conversion, just going to stay with the r-416 since i have some of that laying around and trying to get off as economical as possible since i'm out of work right now due to an injury on the job. thanks in advance for any advice.

If it's just a shaft seal issue why not just change the seal. Sandens are known for shaft seal issues! Should be a shop locally that can replace a seal for you. Other wise you will need some compressor tools to do the job.

thanks trb, i've done quite a bit of a/c work due to i used to be a heavy truck mechanic and it came with the territory, no formal training, just picked it up on the job learning from other guys. all i ever did was r&r, never actually worked on the compressor maybe a clutch or 2 some years back. how much trouble is it to change that seal and what kind of tools does it require? i'm assuming there would at least need to be a seal puller of some sort.

Procedure will be similar to this along with removing the clutch hub.

Try www.sanden.com for their service manual for seal change procedure.
You have the old style axial sealing mechanical seal (carbon against metal), not the better double lip seal that was introduced about 1989/90. The mechanical seals need to be lubed by running the compressor every 2/3 weeks so they would not dry out
Cordially,

Oops, see Tim already posted seal R&R procedure.

i can order everything i need from ackits.com? i'm also trying to print the procedure you listed above but my printer is cutting it in half for some reason. i've went to the sanden website as ice mentioned to try and print it from there and that looks like a little different procedure with the newer type seal.

ok tim, thanks, are there any other tools needed other than what's in the seal service set for removing the clutch assy? and, how much for the new compressor if i want to go that route?

To do a shaft seal in my opinion you need these tools.

91000-A

91273

New Compressor with Clutch $ 334.00 plus freight.
