I'm working on a front manual PTO

[72fj40]

First of all, I must say this site is awesome. Thank you all.

I picked up a questionable 126 about a month ago, along w/some interesting PO mod's. 1st I rebuilt the carb to see if the K301a was good. I got it running w/a knock, then noticed the front pulley was loose, so a new keyway was in order. Tuned it up, adjusted the valves, trued up the head w/a new head gasket, went thru & cleaned up the brakes, wire brushed the deck & replaced some bearings, made new baffles, then paint, fixed the wiring along w/a new volt reg. So now it runs good, w/a very small amount of blowby. Again, thank you for having all this info so handy.

Now for the PTO, The 1st time out w/the 126 I noticed the blades were slowing down in heavy grass. I pulled the type "A" pto & disassembled it. The clutch is cracked & the pressure plate & the pulley side are pitted. I'm thinking about machining these surfaces & has anybody just flipped the pressure plate over? Then all I have to do is get a clutch kit.

Here some pics for your enjoyment.

What is the black paint you used on the underside of the deck?

if the backside of the pressure plate is perfectly flat, i would think flipping it over would work. I have a spare pto that was pitted on the pulley and the pressure plate. My pressure plate is not flat on the other side, so i used sandpaper on a piece of glass to sand the pulley and pressure plate. I removed the pitting and the plate and pulley are perfectly flat.

I used a big cupped wire brush on my big grinder to knock down the surface. Then I used rustoleum rust reformer & gloss black. On something like this I like to apply 2 coats w/a brush. I found this holds up well, & my high pressure washer won't peel it off. The deck was pitted on the bottom, but still pretty solid. I hate to say it but...The top got gloss white, it was what was on my shelf.

I took my front pulley & pressure plate to a friends, he basically has a machine shop in his garage. We chucked up the pulley into the lathe & cleaned up the clutch surface. I would have thought the pulley was cast steel, but its not. Its cast iron. There was no real good way to put the P/P
on the lathe, so we used the surface grinder to true it up to a point. I got it home & was able to get it much better. I used a large flat file making sure to keep it flat on p/p surface & rotated it every so often. The file will show the untouched low spots. When I thought it was getting close I lightly painted the surface w/primer & did the 220 grit sand paper on glass trick as shown in the tech section for head gasket replacement. The low spots will still have paint. I repeated this several times. When I was getting real close, I put down the file & went w/150 grit on glass, paint,220 grit, Repeat. There is 1 low spot, my .0005 feeler gauge wouldn't go under a straight edge. I did this to the back side of the p/p, the used side was just too pitted.

I ordered parts today, hopefully I have results by the end of the week.

Well after some shipping snafu's I finally got my parts, set up the PTO & installed it per the service manual. I have since cut the grass several times & attacked some heavy tall grass & the blades never even thought about slowing down. All is good. I wanted to make sure I finished this post w/the results. I don't know how many times I've searched on various subjects on projects I want to do & end up on an informative thread & at the end of it the OP says "I'll let you know how it works" & never replies back. This seems to be one of the most common problems w/most websites similar to this 1. It just drives me nutz. The main issue I found on this site, is the search function doesn't reconize 3 letters or numbers. So searching for PTO & 3 number CC models becomes difficult. Anyways, all is good & thanks again for such a great website. Ken

Glad you got it fixed!
