2007 Electra Glide Ultra Classic.
55k miles, Big Sucker AC
S&S Powertune Duals.
Have the S&S 551 cams to install, decided to MAYBE have a local indy do it for me.
He asked about the cam plate and pump, told him I wasn't planning on replacing those.
He said he has NEVER replaced cams without replacing pump and plate.(I dont believe that)
The 551's aren't a MAJOR upgrade cam so I'm thinking the stock stuff could handle it just fine...........
Thoughts on doing the plate and pump with the cams?
EDIT.........now he says he WONT do the swap without replacing the plate and pump, so..........
cost..........$2700
Replace cams
Install NEW Cam plate and pump
Dyno tune...........

Me thinks it premature to insist on replacing plate and pump before even seeing the condition of those parts. Is the tech planning to replace the pump and plate with OEM parts or upgrading? Why not DIY the project and decide on replacing plate and pump after seeing the condition of those parts?
Yea he said he wouldn't even do the job unless the pump and plate were replaced with S&S parts.
He said he does a compression and leak down test as well as other things to make sure it dyno's ok.
Seems like a lot money considering I supply the cams.
If you were doing your own work, you could check OP before tear down with a gage. Then tear down and careful inspect pump with precision measuring tools to a service manual specifications. Then pull the top plug in cam plate and flush it. Then carefully inspect bearings.
When you pay someone, the above cost more then the parts. And if they happen to miss something, and have to go in again, and it's the pump or plate or trash they missed, and they say you need to pay more, then you are going to be unhappy and them to.
Let them call the shots and explain what they are guaranteing.
there is no need to replace those parts unless you find an issue when disassembled. they are NOT a requirement, but they are nice. id find a different tech, or do it yourself and take it in to get tuned.

remember that the 07s all have the hydraulic cam plate stock, not the older spring loaded chain tensioners.

I am with marcodarq. I think that refusing to take the job unless OEM parts are replaced with S&S parts without even looking/inspecting the OEM parts is ridiculous. Find another tech or DIY the job and find a tuner other than the current tech. Harbor Freight compression tester and leak down kits won't break the bank and you can DIY the tests as well.
Agreed that it should be checked before deciding on replacing the cam plate and pump. But at 55k miles, I'd replace them while I was in there, if it were mine. And at that point, it's not so much labor because you are there already, it's the cost of the parts, which aren't cheap.
The shop has to warranty his work and protect his reputation, so perhaps he is being cautious. Mabey he has run into this previously and doesn't want to be bitten or have an unhappy customer. But making that demand seems a little much. He could always mentions it a potential item of concern based on mileage to make the customer aware of the possibility it will be needed.
Early Twin cams have a low pressure oil pump with minimal volume. Also they used a spring loaded timing chain tensioner. Not sure what year they tarnsitioned to the new high flow low volume pump and hydraulic chain tensioner but for me if your in the cam chest and your year does not have the improved design you should change the cam plate and tensioner. I went through the original and a 2nd set of tensioners in less than 50K miles before I installed the fix. New High Volume Oil Pump ASM and Billet Plate to support those 211 cams. Purchased this kit before I realized the extent of my problem..
