Krice58 178 #1 Posted 4 hours ago Just picked up this 79 C141 for cheap not running. Found out the lobe on cam for fuel pump was rounded so I put an electric pump on it. Runs good, shakes like crazy. What are you guys doing for replacement bushings on this shaker plate? This is my first one with this setup, all my others were mounted directly to frame.

ri702bill 12,828 #2 Posted 4 hours ago (edited) You have 2 choices for ridgid mounting. One is to purchase the Ebay available CNC machined ones ( I have a used set on a C81 - works great). Or measure the gap from the underside of the plate to the top of the frame & fill it with solid spacers of your making.... IMHO - replacing soggy useless laminated mounts with the same is a waste of time & money. Edited 4 hours ago by ri702bill Share this post Link to post Share on other sites
oliver2-44 11,697 #3 Posted 4 hours ago Wheel Horse Parts and more sells nice machined solid ones Or you can work out a stack of appropriate sized washers. 1 Share this post Link to post Share on other sites
ebinmaine 80,333 #4 Posted 4 hours ago Replace with solid. I'm not sure who sells them. I've seen pics of someone on here that showed a home shop made set. @Ed Kennell ??

Not saying it was or wasn't, but I've never seen a cam lobe worn down by a fuel pump arm. However, an electric pump is a good replacement. 3 1 Share this post Link to post Share on other sites

And eliminates the risk of a leaking diaphragm pumping fuel into the crankcase and destroying an engine and possibly the operator.

I’d never seen it before either. 1 Share this post Link to post Share on other sites
Krice58 178 #9 Posted 3 hours ago How do you install the bushings? I’d assume you’d have to lift the engine somehow? 1 Share this post Link to post Share on other sites

Sorry no pics Eric, but I have eliminated this engine mounting design that depends on four rubber sponges and the drive and PTO belt tension to position the engine. Some I replaced the rubbers with solid spacers and some I cut the angled wings off the cradle plate, removed the tapered bars and bolted the plate directly to the frame with the correct spacers to put the engine at the correct height. All worked well and IMO had the same or less vibration than the rubber mounts. Here is a link to my Low Rider build where I altered the cradle plate to a solid mount. Page #2 shows the mods.

However, an electric pump is a good replacement. There really isn't much of a lobe to begin with but for the sake of discussion: My C160 would be a beast to get the carb primed if I ran out of gas. so I thought the pump was bad and replaced it. Couldn't get any gas to the carb at all. I unbolted it with the lines connected and could get it to pump like crazy by hand. Tried installing it like 10 times with no luck. Went electric and never looked back. 3 Share this post Link to post Share on other sites

I used the steel plate mounts from two sets and turned up solid interlocking aluminum halves & centering rings. Then I powdercoated them all... Those are now installed on the other C81 i purchased from @Sparky. They look almost identical to the OE ones... 2 Share this post Link to post Share on other sites
pfrederi 21,055 #14 Posted 1 hour ago or get a lower PTO hoop holder (or make one) and use spacers like this 3 Share this post Link to post Share on other sites
Goldnboy 1,149 #15 Posted 1 hour ago I just went the rigid mount bushings from performance machine and design...and they do work...but the installation is definitely not easy...if I were to do this again I would do what @pfrederi did above. 2 Share this post Link to post Share on other sites
