head torque specs

[lvhdude]

I had the rear rocker box bolt come out and wedge alongside the exhaust valve spring. It ticked for awhile and I couldn't figure what it was till one of the keepers came out and it went to running on one cylinder. Probably hit the piston and bent the valve. did it at an idle, so I'm pulling the head today. one of my dilemmas is I am not at home and do not have my manual. Can someone provide correct torque specs for the top end? Head bolts, rocker boxes, rocker covers, intake, exhaust, etc? Much thanks. 95 FXDWG stock (pretty much) engine. Also I've been told that 35 lbs is a good alternative to the torque/turn method used by harley, any thoughts? Thanks again, lvhdude

Info from 93HD manual FLT and FXR

Head bolts, be sure holes are clean and dry

Torque sequence

Front Cylinder #1 front left #2 rear left #3 front right #4 rear right
Rear Cylinder #1 rear left #2 front left #3 rear right #4 right front

Clean bolts and lubricate (engine oil)

start at cylinder head bolt #1 and torque to 7 ft lbs than tighten bolts #2 #3 #4 to 7-9 ft lbs

Start again with head bolt #1 #2 #3 #4 and torque to 12 - 14 ft lbs

mark a line cylinder head aligned with a mark on the head bolt and
follow the same torquing sequence and tighten each bolt a 1/4 turn

procedure is finished


Push rods (stock) rear exhaust purple
rear intake blue
front intake yellow
front exhaust green


rocker boxes,
Slowly snug lower rocker box fasteners in small increments using cross pattern. 5/16 bolts torque to 15-18 ft lbs 1/4 bolts torque to 10-13 ft lbs


rocker covers
10-13 ft lbs cross pattern small increments


intake,
intake manifold to cylinder 6-10 ft lbs


exhaust,
not sure flange square to cylinder as possible and snug
equal torque on each nut

Hope this helps

Hey lvhdude how did things work out?

[lvhdude]

It went togeather perfectly, after some hunting for a head gasket. I bought a kit off e-bay that was a very nice kit wit everything, head,(2 sets) base, rocker boxes, intake, carb, exh, all the good stuff but the gaskets were 10and 15 thousands thicker than what came out. I ended up buying a solo gasket from the dealer that was the same part # as what came out and the motor runs great. Oh yeah the kit had all the push rod tube seals, and valve stem seals too. Reliant gasket, 48.00 +10 for freight. Found a pair of manlet SS exhaust valves delivered for 24.00 as oposed to the dealers 52 for 1 valve. dealer was around 100 for a gasket kit. Anyway thanks for the torque specs and sequence. She's up and running great. Joe.
