Exhaust header pipe nut tool

• Print this section

I extracted this recommendation from Ralf Brinkmann off of the Yahoo! Loopframe_Guzzi news group. In Ralf's own words:

I use "DIN 1810 A" wrenches - very common and low priced in Germany (DIN = German Industrial Standard).

Here are a few places where you can purchase the special hook wrench that will permit you to easily tighten and loosen the exhaust header pipe securing nuts. You'll need one wrench. The outside diameter of the exhaust nuts is 1111111 mm.

Rivet removal tool

• Print this section

Allows removal of the rivets which hold the plate onto the steering head. Instructions:

• Place the tool inside the steering head.
• It's helpful to shine a light up the steering head while you look down.
• "Feel" around using the point to find the hole where the rivet is.
• Use a 7/16" wrench to turn the nut and advance the point to push the rivet out.
• You may want to put some tape over the outside of the rivet so it doesn't drop and get lost.

Valve spring compressor tool

• Print this section

I first purchased, bent upon first use, and returned this Craftsman valve spring compressor. Maybe it will work for you, but it didn't for me.

Next, I came across an original valve tool on ebay. It is quite well made but I found it difficult to use.

I finally decided to make my own, homemade valve spring compressor. I'm certainly not the first person to make my own, but I thought I'd share my experience.

• I first picked up an 8" C-Clamp from Harbor Freight for USD $8.55. A 6" C-Clamp is easier to find, but does not quite have the opening needed and the throat is too narrow to get to the exhaust valve (although it works for the intake valve). The C-Clamp I found has nice smooth, fine threads...which give a much better mechanical advantage over rougher, coarser threads. I already had an 8" Craftsman C-Clamp, but its threads were rough and coarse, so I decided on the Harbor Freight C-Clamp.
• Next, I picked up a 3/4" electrical conduit coupler from my local Ace hardware store for less than USD $1.50. The diameter is just right for fitting over the collar. I then had to grind out large chunks on two sides to facilitate removal and installation of the split collets.
• Finally, I welded the coupler to the C-Clamp.

There you have it. About USD $10.00 for a specialized tool that works absolutely beautifully!

Wrist pin puller tool

• Print this section

I extracted this recommendation from Charlie Mullendore of Antietam Classic Cycle off of the Yahoo! Loopframe_Guzzi news group. In Charlie's own words:

I made a wrist pin puller out of a PVC pipe nipple, a 3/8" stove bolt w/nut and some washers. Ground the head of the stove bolt down to the same diameter as the piston pin and wrapped a little duct tape around the shaft so that it would fit into the pin snug. Cost me about USD $2.00 and worked just fine.
