Metal from the recycling yards is dirt cheap.]]></description>

			<description><![CDATA[Hmmmm....about $90 for a blank (undrilled) and close to $300 for the hub with the bore already drilled. Yikes! These must be pretty special!]]></description>

			<description><![CDATA[I just looked again at the spacer on the UH site. It is made the same as mine with the recess machined to clear the crank bolts, the outer holes match the sleeve mounting holes. I refer to this spacer as a cap because it caps the crank bolts in the flywheel.]]></description>

			<description><![CDATA[Yes Guy it just creates a flat backing plate for the sleeve and gasket to mate to. Mine caps over the flywheel bolts because that is what made sense to me at the time. I was being thrifty, thinking I could have it made localy rather then get it from UH and save some $. I was wrong spending twice as much as getting what they have. Oh well...I do suppose You could have a spacer sitting on top of the crank bolts and not have a rim extending down to the flywheel suface. Much simplier.]]></description>

			<description><![CDATA[Greg, I noticed that Universal sells a spacer without a cap that goes between the sleeve and the flywheel. I'm wondering why you chose to create a "cap" along with your spacer? Is it just to keep the grease in?]]></description>

			<description><![CDATA[Mike, I built up the engine stand per plan using the provided mod. drawing for the EJ22 from UH. I changed or altered nothing. The rearward engine mount bolts go straight up through the center of the short upright square tube risers and upper stand rail, then through the 1" square tube spacers and into the engine block threaded holes (M10 1.5). When time came to fit the engine to the stand I was pleased to find the mounting positions all lined up as required. I did need to shim the rearward mounts aprox 3/16" using washers along with the 1" spacers to level the engine fore and aft. This could have been that my bent angle iron forward mount tabs stood a bit too tall. I didn't drill the mount hole s into the angled tabs until I marked there location as the stand was fit to the engine, but seeing how it all work with the plan dimensions, doing it over I would drill the holes as indicated, they are correct. The bearings for the drive shaft have 3/16" shims under them to compensate for the shiming up of the emgine.The upper prop drive pulley fits in the provided space no problem, I too had my reservations about this wider pulley, but it works just fine. I used 3/4" aluminum "lite Bar" for the tightening spacers under the upper bearings and that got the belt tension pretty close. The spacers you see are the designed method of tension, removing them allows the slack to install the belt and line up the pulleys. To tension things up the forward shim is put in place and then simply use the prop shaft as a lever to tension the belt and slide the shim under the rear upper bearing. I will however add a idler pulley to the mix to compensate for stretch and run in of the belt as I move on with the build once I find a suitable pulley. UH I don't believe uses idler pulleys. I can only think that they shim the shaft up a bit over tight and run it in. Anyway....Thats the way thing went together for me. I did find that with the engine bolted up there is clearance for the stock oil filter , but not enough to remove it. I went to NAPA and found an oil filter that is about 1/2" lower (NAPA GOLD 1064) and that resolved the clearance problem. I am really happy with the whole setup as she sits right now. It is amazing to see that when the engine is running, nothing moves!! I just have the stand sitting on the wheeled platform I made, and it just sits there, no vibration at all, just smooth. Its really cool. Well, that got long.... I hope it cleared up some things for you. I would be happy to take actual measurements of anything you would require for your planning, just let me know. Best of luck with your build and keep us all in the loop. Greg]]></description>
