The long block rarely wears out on its own. What these engines need is resealing at the front cover, rear main and pan, plus attention to the killer dowel pin, which usually gives no warning before it drops.\u003c\/p\u003e\u003c\/div\u003e\u003cdiv class=\"sds-copy-guide\"\u003e\n\u003ch2\u003eEngine components on the 1989-1993 RAM 5.9L Cummins\u003c\/h2\u003e\n\u003cp\u003eThe first-gen \u003ca href=\"\/collections\/cummins\"\u003e5.9L Cummins\u003c\/a\u003e is a cast-iron block and head with a solid-lifter camshaft, and the camshaft and injection pump are gear-driven off the front of the block. Blocks from 1989 through 1997.5 use 14 mm main-cap bolts, and the factory connecting rods are forged steel. A 1993 D250 was documented at 620,000 miles with the engine untouched except for valve adjustments, so for most owners the parts on this page are about leaks and the front gear train, not worn-out internals.\u003c\/p\u003e\n\u003ch2\u003eWhat fails and why\u003c\/h2\u003e\n\u003cp\u003eThree problems bring first-gen owners here:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe killer dowel pin.\u003c\/strong\u003e The dowel that locates the front gear housing can work out of its bore with heat cycles and vibration and drop into the timing gears. If it wedges between the cam gear and injection pump gear, it can crack the gear, the cam nose or the housing. A cracked gear housing is a cam-out job.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront cover and crank seal leaks.\u003c\/strong\u003e Oil weeping behind the damper and down the front of the block is common on engines past 25 years old. With the front cover off, replace the front crank seal and the cover gasket.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear main and pan rail leaks.\u003c\/strong\u003e High-mileage engines drip at the bellhousing seam and the pan rail. The rear seal is serviced with a wear sleeve.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe factory harmonic balancer is also an age item. Its rubber bond degrades over decades, and because the RPM sensor reads notches in the damper, a shifted damper can upset the engine speed signal.\u003c\/p\u003e\n\u003ch2\u003eStock replacement vs. upgrade\u003c\/h2\u003e\n\u003cp\u003eFor a reseal, stay OEM-grade: genuine Cummins and MAHLE gaskets and seals and a stock-replacement balancer. Rebuilds and power builds are a different job. One documented high-output 1993 engine went together with stock-compression MAHLE cast pistons, shot-peened factory rods with ARP rod bolts and a fire-ringed block. Heavier valve springs and pushrods go in when you run an exhaust brake or a bigger turbo, and XDP's performance balancer is the alternative to a stock-replacement unit.\u003c\/p\u003e\n\u003ch2\u003eWhat we carry\u003c\/h2\u003e\n\u003cp\u003e\u003ca href=\"\/collections\/cummins-genuine-parts\"\u003eCummins\u003c\/a\u003e genuine parts: the front crankshaft seal service kit, front timing cover with crank seal, timing cover gasket, camshaft gear, standard piston kit, upper engine gasket kits, rear main seals including one with a repair sleeve, the oil pump and the harmonic balancer. \u003ca href=\"\/collections\/mahle\"\u003eMAHLE\u003c\/a\u003e brings head sets, cylinder head gaskets, the lower engine gasket set, rear main and timing cover seals, a rear main seal set and a front cover gasket.

The Cummins front timing cover, the Cummins and MAHLE timing cover gaskets and the Cummins and XDP stock-replacement balancers are listed 1989-1993 only, and the Dorman vacuum pump is 1989-1991. The standard Cummins piston kit starts at 1991.5. Piston cooling nozzles need a second look: the factory-style nozzle sold for the 5.9L is listed for 1994-2002, so confirm the listing covers your block before you buy. For front-cover work, 20 bolts hold the gear cover, and you will want a seal driver, a brass punch, a feeler gauge and a barring tool. Never turn the engine with the timing pin engaged; it will break off in the front cover.\u003c\/p\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eWhat should I replace while the front gear cover is off?\u003c\/h3\u003e\n\u003cp\u003eThe front crankshaft seal and the cover gasket at minimum, plus a killer dowel pin tab if there is no proof one was installed. Cummins offers a front crank seal service kit and a seal with wear sleeve, and both Cummins and MAHLE make the 1989-1993 timing cover gasket. Getting there means pulling the fan, shroud, belt and damper, so look over the accessory drive while you are in there.\u003c\/p\u003e\n\u003ch3\u003eIs the killer dowel pin really a risk on a 1989-1993 engine?\u003c\/h3\u003e\n\u003cp\u003eYes. The 1994-1998 trucks see it most, but first gens are in the affected range, and it can happen at any age. The prevention tab is held by the neighboring gear cover bolt and physically blocks the dowel from backing out.\u003c\/p\u003e\n\u003ch3\u003eWill a 1994-1998 12-valve rebuild part fit my 1991 truck?\u003c\/h3\u003e\n\u003cp\u003eOften, but not always. Many rebuild parts span 1989-1998, while fueling parts and the turbine housing differ between non-intercooled and intercooled engines, and some parts on this page carry narrower ranges.

In fact, it works with the frost plug in place, blown out, or leaking due to the robust 0-ring seal.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cdiv style=\"margin-left: 40px;\"\u003e\n\u003cul\u003e\n\u003cli class=\"li1\" style=\"margin: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-kerning: auto; font-optical-sizing: auto; font-feature-settings: normal; font-variation-settings: normal; font-stretch: normal; line-height: normal; font-family: Helvetica;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003e\u003cspan style=\"font-family: tahoma, geneva, sans-serif;\"\u003eBolt-On Installation\u003c\/span\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"li1\" style=\"margin: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-kerning: auto; font-optical-sizing: auto; font-feature-settings: normal; font-variation-settings: normal; font-stretch: normal; line-height: normal; font-family: Helvetica;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003e\u003cspan style=\"font-family: tahoma, geneva, sans-serif;\"\u003eFor Rear Coolant Freeze Plug\u003c\/span\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"li1\" style=\"margin: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-kerning: auto; font-optical-sizing: auto; font-feature-settings: normal; font-variation-settings: normal; font-stretch: normal; line-height: normal; font-family: Helvetica;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003e\u003cspan style=\"font-family: tahoma, geneva, sans-serif;\"\u003eRemoval Of Old Freeze Plug Not Required\u003c\/span\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"BD Diesel","offers":[{"title":"Default Title","offer_id":50374650855712,"sku":"1040022","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0916\/3043\/6640\/files\/bd-diesel-1040022-killer-frost-plug-plate-1989-2002-cummins-5660575.webp?v=1779547029"},{"product_id":"hamilton-cams-07-s-001-performance-cummins-12-valve-springs-1989-1998-cummins","title":"Hamilton Cams 07-s-001 Performance Cummins 12 Valve springs (1989-1998 5.9L Cummins)","description":"\u003ch2 data-start=\"0\" data-end=\"439\"\u003e\u003cstrong data-start=\"0\" data-end=\"86\"\u003eConical Beehive Valve Springs (155 lbs Seat Pressure) – Retainers \u0026amp; Locks Included\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp data-start=\"0\" data-end=\"439\"\u003eUpgrade your 12-valve Cummins valvetrain with our\u003cspan\u003e \u003c\/span\u003e\u003cstrong data-start=\"139\" data-end=\"172\"\u003eConical Beehive Valve Springs\u003c\/strong\u003e, delivering\u003cspan\u003e \u003c\/span\u003e\u003cstrong data-start=\"185\" data-end=\"213\"\u003e155 lbs of seat pressure\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eto keep valves firmly under control up to 4,500rpm\u003cstrong data-start=\"260\" data-end=\"273\"\u003e RPM\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eor\u003cspan\u003e \u003c\/span\u003e\u003cstrong data-start=\"277\" data-end=\"288\"\u003e65lbs\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eof boost\/drive pressure.

If you are thinking it is too small for your hp goals, think again.

On 1989-1993 trucks, exhaust manifold bolts loosen and manifold gaskets leak under heat cycling, which shows up as ticking at the head, soot streaks at the manifold and creeping EGT. On the same trucks, the intake grid heater sits between the air horn and the intake manifold on its own gaskets, and a leak there shows as a boost hiss at the horn and oily residue around the flange.

On 1991.5-2002 engines, the tandem vacuum and power-steering pump can leak engine oil where the power-steering pump shaft enters the rear of the pump. It drips on the floor from the pump area, and it has its own reseal kit. On 1998.5-2002 24-valves, the crankcase breather sits at the front of the engine. It can push a lot of oil out on steep descents and drip on the driveway, and it is often mistaken for a front-axle seal leak. Dodge TSB 09-002-02 moves the breather inlet back alongside the engine.

A 1998 Ram can be a 12-valve or a 24-valve, and many engine parts do not interchange across that split, so identify the engine if you are ordering other parts with this seal.

Every 5.9L Cummins through 2007 vents the crankcase through an open road-draft tube, and on second-gen trucks that drip lands near the front differential yoke, where it has led to plenty of needless yoke-seal replacements. Rule the breather out first. If the crank seal is the leak, this kit is the repair.\u003c\/p\u003e\n\u003cp\u003eThe other reason to keep this seal on hand is any job that takes the front cover off. On 12-valves the big one is the killer dowel pin: the steel dowel that locates the front gear housing can vibrate out of its bore and drop into the timing gears, where it can crack the cam nose or the gear housing. KDP issues affect 1989-1998 12-valves, with most failures on 1994-1998 engines. The fix is a tab held by a gear-cover bolt with thread locker, and the standard advice is to replace the front crank seal while the cover is off. The same preventive fix is offered for 1998.5-2002 engines, done when the front cover or crank seal comes off.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cul\u003e\u003cli\u003eOne Cummins 3937111 Genuine Front Crankshaft Seal Service Kit\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eQuality Materials\u003c\/li\u003e\n\u003cli\u003eDirect-Fit Replacement\u003c\/li\u003e\n\u003cli\u003eGenuine OE Component\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eAbout Cummins\u003c\/h2\u003e\n\u003cp\u003eCummins started in Columbus, Indiana, in 1919 and still calls it home.

The best-known threat to it is the killer dowel pin. That steel dowel locates the front gear housing on the block, and heat cycles and vibration can work it out of its bore and drop it into the timing gears. If it falls into the oil pan, no harm done. If it wedges between the cam gear and the injection pump gear, it can crack the cam gear, the cam nose or the gear housing, and the worst case is an engine that cannot be repaired.\u003c\/p\u003e\n\u003cp\u003eThe 1994-1998 P7100 trucks are the highest-risk years, because the heavier pump adds vibration to the gear case. The 1989-1993 VE trucks are in the affected range too, and some 1999 24-valve trucks have had it.\u003c\/p\u003e\n\u003cp\u003eIf you are replacing a cam gear, the gear cover is already off, and that is the time to deal with the cause. A KDP tab is held by the neighboring gear-cover bolt with red thread locker at 18 ft-lb, and it physically keeps the dowel from backing out. Replace the front crankshaft seal while the cover is off, and let the RTV on the cover cure 24 hours before you start the engine.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOne Genuine Cummins camshaft gear, part number 3929028\u003c\/li\u003e\n\u003cli\u003eGear only: gaskets, seals and KDP hardware are not listed with it\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eAbout Cummins\u003c\/h2\u003e\n\u003cp\u003eCummins started in Columbus, Indiana, in 1919 and still has its headquarters there, with more than a hundred years of building diesel engines behind it.
