Hi: Looking for some advice. I need to replace the 2 brake springs on my WD on the right side. Of course, in order to do this, it appears the seat needs to be removed. The actual brake cover removes fine, the seat not so much.

Is there a correct method or a better phrase "path of least resistance" in removing the seat to replace both right brake springs? Also are these seat parts available if i get in trouble? For now, I just tightened the bolts on the brake cover back up. Much easier to drive with no brake springs than no seat. Thanks in advance for any assistance!

I don't remember the seat removal being a big deal. Unbolt and remove...do spring work and bolt back on. What am I not seeing?

Thanks for your reply. In my case I see 3 possible options and there certainly could be more. It appears a person could remove the top shock bolt or the bottom shock bolt and either would accomplish the task. However ,mine have never been removed. The bolts are like wielded in. The bushings are really in tough shape I goggled around and it appears that replacement parts called a bushing seat bolt, a seat bushing only or perhaps both. Looks like they run around $20 a piece. I was hoping to avoid all of this at this time and just replace the 2 brake springs which I have on hand.

The 3rd option appears to remove a large bolt at the base of the seat which would eliminate dealing with the shock bolts/bushing entirely. Would this be the preferred route? Or is their another way that is a "best practise" when removing this right brake cover plate.

Thanks.

It's been a long,long time but I thought the seat is held on with the same two bolts/cap screws that holds the brake covers.

Just Two Small Bolts They Hold The Seat And The Brake Cover On Then You Can Replace The Spring Through The Top Not Hard To Do

I wish it was that easy. There is a large bolt that attaches the seat to the frame in front of the front of the brake cover. The brake cover can not be removed unless either the front bolt is removed or the rear shock is removed so that the seat can be tilted back to remove the cover This is a later model WD. Serial number: #104589. Hope that helps. Thanks.

Just take the brake cover off that side and do it all through that hole...fairly easy to do and I've never had any problems doing it that way. I always use a real hard piece of #9 wire to latch onto and pull the larger spring through the hole...it's easier that way to me.

I Never Take The Seat Apart To Change the Springs Front Bolt Will Come Out If You Pull The Bracket Up When You Loosen The Bolt I Worked On Allis For More Then 50 Years But You Can Take The Front Bolt Out To Make It Easy

EP,

If the bolts you want to take out are usted solid which is pretty typical of these old machines. You may have to cut them off ant remove the seat. That large front one can be a real pain. You can get all the parts but plan on several hours fighting the rusted items.

And several dolars to get the parts to put it back together. The good news is if you invest the time and money you will really enjoy having brakes and a seat that can be removed in your life time too!:)

Regards,

Chris

Not a problem. If WD, remove two bolts in cover and tilt seat back out of the way. If WD45, remove two bolts on cover, one bolt behind housing and remove seat assembly. MACK

Ive removed the complete seat assembly from both My WD45s take it off as a complete assembly don't disassemble it or remove the shock unless your putting new bushings in.
