Title: 37N Andrews Cams
Post by: KnuckleDragger on May 09, 2019, 11:55:25 AM
Hello....
Im installing a set of 37N andrews cams and changing up the support plate to hydraulic tensioners on my 2005 softail They are calling for 25355-06 support plate and 26037-06 oil pump. Are the 2007-2016 hydraulic support plates not basically all the same? Can i not use any support plate from these years?

Thx for your input!! :pop:

I think the plates are the same except that later ones eliminated the bushing on the crank area. #25355-06A.

Yes, they are functionally the same. Use which ever year you can find.

I believe there are differences in the oil passages between TC88A and TC88B support plates, you may need to ensure you get a plate with the proper oil passages.

The oil passage difference is a function of the A and B engine cases.  Both cases use the same support plate.

your Bike is an 05. You could do an Andrews 48n too!

most pros will recommend more compression over stock for 37s.  i'd agree if you like torque down low, the 37 needs to be wound up to feel good with stock compression.  mines a 95" and it still feels a little lazy, but it's a softail so doesn't take much to get it moving.

Why not get the heads ported and valves reworked to run more lift, then go with 57's.

Ooooookkkkkk..... :bf:

So i got this 97 build back together....fires up slick as sh**....run it 15 secs....oil pressure light still on ....shut it down...check oil ( just in case ) ....oil is right up .....fire it back up , still no pressure, lights still on.

I updated the camplate/oil pump with a 2005 hydraulic(worked perfectly in the 2005) took it apart, cleaned it up , lubed it good before i assembled it. I know in the 1999 models there is one oil gallery that has to be plugged on the plate. but this bike is a 2006 softail.

Any input before i rip this cam/ oil pump chest apart again?
Im going to grab an actual oil pressure gauge from shop tomorrow and check the pressure manaully but its clacking a bit so i think the pressure is nil.

I ALWAYS pull the plugs and fuse and turn a engine over until the oil light goes out wait a few minutes and do it again to prove it wasn't a fluke after major engine work before it is started. Sounds like you need to go back in and find the reason u have no oil pressure. Bob

Looks like you have to rip out the camplate again and check for proper installation of o-rings, softail engine needs three o-rings: two small ones between camplate and engine case and the large one down low between oil pump and engine case. Also verify carefully the correct re-assembly of the oil pump towards the cam plate.

It has happened to me twice, one of the o-rings behind the camplate fell out at assembly. My fault.
