Hi,

Anyone rebuild a Wilbur's type 633 shock themselves?
If not, who is the go to for quality and price in USA?

Glenn

Here is a pic of my shock. I know it's a 630 series but with external reservoir, not sure of model.
Shock has started to leak, so want to do a seal and fluid change.

I have used this company for ages. They are competent professionals. Based in New Jersey, so relatively close to you, they also handle Hyperpro, YSS and reluctantly, Öhlins. They also rebuild the "non-rebuildable" BMW ESA shockies.

Thanks Two, I just sent an inquiry to EPM.

I had one redone by Ted Porter's Beemershop. They probably don't have the best prices but are reasonable and they know Ks.

Nitpicking: Wilbers, not Wilburs.

If the horse can talk then you have to address him as Mr.

Flighty.

Sometimes threads just take 'flight'.

Now we've got flying horses?

Quick reply from EPM and I will be sending my shock and adjuster to them.

"Unfortunately, we’re unable to sell repair parts for Wilbers shocks due to company policy. If you are not a suspension professional, it’s not recommendable to try a shock service on your own due to the attention to detail required to properly disassemble and reassemble the parts, as well as missing the vacuum pumps required to fill them correctly.
 
You’re looking at ~$200-$220 for the shock service, $75 for the service on the Hydraulic Preload Adjuster, and a turn around time of 1-2 weeks once the shock arrives here.
 
Thank you,

Given current labour costs in the powersports biz, that seems reasonable to me. They quoted me $295 all up on a rear ESA shock for a late model Beemer, which BMW say is not rebuildable. Nudge, wink.

I had them build a to-my-spec Hyperpro rear for my Big Block. It is a thing of beauty, simple, but highly adjustable. The first rebuild, mileage not limited, is free.

For those closer to the west coast of the US, I do also recommend Ted Porter. Get on the phone with them and you will either come away a suspension specialist or your head will explode!

Yes, this is very reasonable.

Nice quick turn around by EPM For USD 240. I got the shock back Friday night and got it mounted and adjusted Saturday.

When the tech was done repairing, he called me which was a nice touch. He said there was no hard parts damage and asking if I had any questions. I asked him about my external pre-load adjuster and he said that it was good for 11mm of adjustment.

A = 452 mm
B = 462 mm
C = 476 mm
Length of shock exposed rod = 70 mm
Static Sag = -( A – B) = 10 mm; Ss/70 = 10/70 = 14.2%; Road setting approx.10-15%*
Dynamic Sag = -(A-C) = 24 mm; Sd/70 = 24/70 = 34.3%; dynamic sag should be approx. 1/3* of the total wheel travel

Money well spent! Good service, useful information, and a quick turnaround time. This too has been my experience in dealing with EPM both as a dealer and privately over the years.

Just took my rig out for a test ride on rough roads which many are around me, and it is perfect! Probably the last ride of the season.

Goodonya! It nearly always amazes (used to, at least) me how little the "ramp" for preload adjustment actually is on a quality piece of suspension. In the case of your Wilbers, 11mm. I had an öhlins for an R1150RT rebuilt by a professional outfit some years ago, after a punishing ride to Alaska from Washington state and back, and was told the preload range was barely 6mm. Of course, in the real world, it feels as though it is doing the job of levelling once you make the adjustment. That 6mm - or 11mm - translates into much more spring movement or tension when fiddled with.

Yes, my thoughts as well. I expected the adjustment range to be greater but it works!
