Superpac 6620 1999 Parts Catalog

Let me tell you what happens when you order a seal or a hose without a factory part number. You get the wrong part. You lose a day. The machine sits. That’s why I keep a copy of the Superpac 6620 1999 Parts Catalog on the bench next to the torque wrenches. It’s the OEM document, 66 pages, printed on Superpac’s own press in Canada, and it covers every roller with serial number 101521 and up. If you’re turning wrenches on a 6620 compactor, this is the reference that keeps your rebuild from turning into a scavenger hunt.

Frames & Cowling Breakdown

Section 1 of the catalog breaks down the chassis into individual groups: ENGINE HOOD GROUP, FRONT FRAME, ARTICULATION, REAR FRAME (two separate sheets, because the left and right halves differ), FRONT PEDESTAL, ROPS, SEAT, and DECALS. Each group has an exploded drawing with numbered callouts that match the parts list. Need the ROPS hardware kit? You look up the illustration on page 1-7, grab the part number, and call your dealer. No guessing. No aftermarket cross-reference that might be off by a thread pitch.

Engine & Controls: What the Manual Covers

Section 2 is dedicated to the engine group and all the control linkages. ENGINE GROUP, RAD / OIL COOLER GROUP, AIR CLEANER GROUP, ALTERNATOR, STARTER & FUEL LINE – it’s all there. The forward/reverse control plate and throttle cable assemblies are drawn with every bracket, bushing, and spring. If you’ve ever had a throttle return spring break and tried to match it by eye at the parts store, you know why having the OEM part number matters. This catalog gives you that number. Period.

3 Drum Assemblies Detailed

Section 3 covers everything that spins and compacts: DRUM ASSEMBLY – DRIVE, DRUM ASSEMBLY – ECCENTRIC SHAFT, and DRUM ASSEMBLY – CARRIER. Also included are the drum scrapers for both smooth and padfoot configurations, plus tires and rims. The eccentric shaft assembly is where most vibration issues start. The factory drawing shows you the bearing stack, the seal orientation, and the exact part numbers for each component. You don’t need to measure the old bearing – the manual tells you what it is.

How to Order O-Rings Correctly

On page 2 of this catalog, Superpac includes a dedicated section on ordering O-rings. It identifies 37° J.I.C. flare and standard SAE O-rings with cross-reference to the part numbers. If you use the wrong O-ring material on a vibratory roller, you’ll be chasing hydraulic leaks every 50 hours. This manual tells you which O-ring goes where, so you order the right one the first time. That’s not a luxury – that’s basic shop discipline.

Quick Reference Chart – Filters and Belts

Flip to the Quick Reference Chart for Filters and Belts on page 2 of the overview section. It lists every filter and belt on the machine, sorted by serial number range. Engine oil filter, hydraulic return filter, air cleaner element, fan belt – all with the Superpac part number. No need to decode aftermarket lookup tables. The factory part number is right there. That chart alone is worth the price of the access.

Source Validity: OEM vs Aftermarket

I’ve been burned by third-party parts catalogs that re-draw the illustrations and omit the OEM part numbers. This is not one of those. This is a scanned copy of the original Superpac parts manual, part number 208185, dated September 1999. The pages are clean, the callouts are legible, and the indexing works. If you need a part for a 6620, you pull the number from this document, not from a forum post. Aftermarket documentation? Leave it for the pickup trucks. On a compaction roller, you want the factory spec. Automotive Industry Overview has plenty of examples of what happens when parts are mismatched – but your roller doesn’t care about examples. It cares about the right part.

Frequently Asked Questions

Does this catalog include torque specs?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views. Torque specs are in the service manual. Don’t guess a bolt torque from a parts drawing.

What serial numbers are covered?

Rollers with serial number 101521 and up. If your machine is older, check the front cover – the manual specifies the S/N range. If yours is earlier, you need the previous edition.

Can I use this to rebuild the engine?

You can use it to identify every nut, bolt, seal, and gasket in the engine group – section 2-1 shows the complete engine assembly with part numbers. But for assembly procedures, clearances, and torque sequences, you need the service manual. Parts catalog tells you what; service manual tells you how.

Is this a photocopy or a reprint?

This is a high-resolution scan of the original factory manual printed in 1999. The pages are not retyped or redrawn. The part numbers are the same numbers Superpac stamped on the original print. Order the part, and it’s the right one.

You’ve got a 6620 roller on the shop floor with a hydraulic leak in the steering plumbing, or a worn eccentric shaft bearing, or a cracked engine hood. The factory manual is the difference between fixing it this afternoon and waiting for the wrong part to arrive next week. Access the Factory Manual now and keep it on your toolbox tablet or printed out. Your machine – and your wallet – will thank you.
