2305 Valve Settings

ejb17 · May 1, 2009

We bought a used 2305 a month or so ago and forgot to order the service manual. It now has 43 hours on it and it sounds like it may need a valve adjustment. It has a tick that is audible. Could someone please give me the settings. A guy I work with has an older 2210 but do not know if they are exactly the same valve spec. Thanks in advance.

I would call your dealer and let them know that you have a ticking motor. The last thing I would want is a warranty voided because it was worked on internally by an owner.

If my engine was ticking at 43 hours, I would have my tractor at a GOOD dealer and expect it fixed and noted under warranty. IMHO, you engine should not tick at 43, or even 400 hours.

You are correct and I agree-but-I know a valve check is normal maintanence and they will charge me. I work on class 8 trucks so I can do it and if it still ticks afterwards it is headed right to their door. How does warranty work when I bought it on a private sale? The same dealer the previous owner bought it from is the same dealer I use-just different location.

The warranty is the warranty. It works like a car. Call your dealer with the VIN.

I agree, checking valve tolerance is not a big deal. BUT, I am sure they will know someone has been "inside" the motor since the wrench will take off some paint.

I also do not think it would be charged to you. But i completely understand wanting to do the work yourself, knowing its correctly done. You just put yourself in a situation (maybe) if you do the work youself and its more serious.

I would take pictures and document what you are doing, just incase this tick is a piston.

nmu98 is right... let the dealer know about the problem - first - before you do anything!

Don't put yourself in a poor negotiating position by giving them some 2nd thoughts about what you did or did not do to the the tractor..

Usually there is no warranty on used tractors.

I was told by the JD dealer that the warranty on the 2305 I am buying is transferable. told same by another JD dealer and he was talking about a 100 hour used 2305,said remainder of warranty went to new owner. SO if yours is still within time limit should be covered,I would think.

Valve Clearance Adjustment
Reason:
To maintain proper clearance between valves and rocker
arms for maximum compression and valve train life.
Equipment:
Feeler Gauge
10 mm Box End Wrench
Flat Blade Screwdriver
17 mm Wrench
Procedure:
1. Park machine safely. See 撤ark Machine Safely on
page 3 " in the Safety section.
2. Engine must be cool (room temperature) before valve
clearance is checked.
3. Open hood.
4. Be sure ignition key is OFF before attempting to turn
engine by hand.
5. Remove air cleaner assembly and bracket.
6. Remove rocker arm cover.
Note: Top Dead Center (TDC) is when the piston is at
its highest point of travel in the cylinder on the
compression stroke. Number one cylinder is located at
rear of engine (flywheel side).

7. Locate timing marks on the flywheel on the right side of
the engine behind the fuel filter.
8. Turn the crankshaft in the direction of engine rotation
(counterclockwise). Align number one (A) TDC mark on the
flywheel (B) with timing mark on flywheel guard (C).
Note: When number 1 top dead center mark (B) is
reached, the rocker arms for the number 1 cylinder will
be motionless as the crankshaft is rotated. If rocker
arms are still moving when TDC is approached, rotate
crankshaft one full revolution and try again.
9. Try to move rocker arms and/or push rods for number 1
cylinder:
If rocker arm and push rod are loose, the piston is at
TDC on the compression stroke and you may proceed to
step 11.
If rocker arms and/or push rods are not loose, rotate
flywheel one revolution (360ｰ), and recheck rocker arm
and push rods.

10.Measure and adjust valve clearance only on the four
valves indicated above with black arrows while number 1
piston is at TDC on compression stroke.

11.Slide feeler gauge between valve cap (C) and rocker
arm to measure clearance.
T6105BF
12.To adjust valves, loosen lock nut (D) and turn adjusting
screw (E) until blade of feeler gauge can be inserted
between rocker arm and valve cap. Turn adjusting screw to
obtain a slight drag on feeler gage. Hold adjusting screw
while tightening lock nut.
13.Recheck valve clearance after tightening lock nut.
valve cap
14.Check that valve cap (F) on end of valve stem remained
seated on valve and inside valve spring retainer.
15.Turn crankshaft pulley one revolution (360ｰ) to the
number 1 TDC mark again. This puts the piston in number
1 cylinder at TDC on the exhaust stroke.

16.Measure and adjust valve clearance on the last two
valves (black arrows) with number 1 piston at TDC of
exhaust stroke.
17.Install rocker arm cover and bolts to specification.
18.Install air cleaner bracket and air cleaner.
Specifications:
Valve Clearance . . . . . . . . 0.15 - 0.25 mm (0.006 - 0.010
in.)
Rocker Cover Bolt Torque . . . . . . . . . . 11 Nm (97 lb-in.)
